Parts cleaning in the metal working and tooling industry

REQUIREMENTS

The cleaning of electric motors requires fast, damage-free and complete cleaning, often for inspection or repair. Oily windings, dirty end shields, rotors, bearing covers, etc. are cleaned.

In precision mechanics, in summer or at high outside temperatures, care must be taken to ensure that the cooling fins of the electric motors (and, if applicable, the heat exchangers) on the machine tools are dust-free and properly cleaned. Otherwise, the cooling system will not be effective, the bath temperature cannot be kept constant, and trouble-free operation cannot be ascertained.

OUR SOLUTION: LOW PRESSURE HOT CLEANING

Low-pressure hot cleaning, on the other hand, offers a gentle and cost-effective alternative: Even fine lamellae are reached and can be cleaned without damage at a low pressure of up to 7.5 bar. At the same time, the high working temperature of 95°C ensures efficient and fast cleaning.

With the right nozzles, cleaning can also be carried out between the plates and slats. If necessary, an alkaline or acidic cleaner can be added at a low dosage.

Dirt is removed and transported away with low pressure and low water consumption, and the process water can be recycled in the unit using a special recycling process. This reduces disposal costs and protects the environment.

Another advantage is that even large and unwieldy heat exchangers can be cleaned on site, as the ph-cleantec units are mobile and self-sufficient due to their tanks. This saves time by eliminating assembly and travel times, and is efficient because the heat exchangers can be directly reinstalled instead of being sent in and/or centrally cleaned.

YOUR ADVANTAGES

• Efficiency/quality: Fast and thorough cleaning, especially of oily contamination, due to the high working temperature of up to 95°C. With the right nozzles, cleaning between the plates or lamellae is also easy.
• No damage: Thanks to the low pressure, even fragile parts such as the lamellae are not damaged.
• Mobility: Cleaning on site - the units are mobile and self-sufficient - saves travelling and reloading times.
• Occupational safety and environmental protection/chemicals: Very few chemicals, if any, are needed; this protects the environment, increases occupational safety and reduces costs.
• Economic efficiency: Significantly less working time for cleaning, as well as for travel and reloading times; fewer chemicals.
• Universal applicability of the hot cleaning devices: These can be used for maintenance and servicing or for cleaning machines and parts.
• Overall: Comparatively low investment and hardly any running costs, but high efficiency, excellent quality, and no damage.

OUR SOLUTION

• Low-pressure hot cleaning units operate at 7.5 or up to 14 bar and up to 95°C
• Fast and efficient cleaning due to less manual handling
• Mobile along the production line or permanently integrated into the production process.
• Autonomous thanks to the integrated 60-litre tank
• Easy connection to the building's water and power supply system
• Possibility of adding alkaline detergents for more intensive cleaning
• Water recycling for better protection of health and the environment

YOUR ADVANTAGES

• Gentle and efficient cleaning even of nano-coated surfaces
• Contamination from solids, oils, etc. at temperatures of up to 95°C is cleaned off quickly and easily; with cold cleaning agents, this is only possible with great effort and time
• As a rule, 80% less cleaning time by spray cleaning with hot water compared to cold wash tables or cold cleaning agents
• Up to 95% less chemicals and water consumption
• No splashback, no aerosols, therefore unproblematic use inside the workshop
• Devices can be used universally for various other applications
• Forgoing chemicals protects health of employees, the environment, and saves costs
• Economics: Low investment, hardly any running costs, excellent quality, and significant time savings

REQUIREMENTS

Hydraulic blocks are used in a variety of applications. Cleaning the often complex blocks is a particular challenge, as the hydraulic oils as well as all dirt and dust residues in the complete block must be removed, but at the same time accessibility is not given, especially for conventional cleaning methods.

OUR SOLUTION

With the help of low-pressure hot cleaning, dust- and grease-free cleaning is easily possible even without aggressive cleaners.

Thanks to a wide range of spray tools and nozzles, even deep passages and channels can be cleaned very well. With the help of blind hole nozzles, even the bottom of deep blind holes can be reached and cleaned, and with flexible nozzles it is even possible to clean “around the corner”. Due to the low pressure, the contamination is rinsed out completely and without any problems.

In this way, low-pressure hot cleaning meets the high cleanliness requirements of the hydraulics industry with regard to residual dirt and solid particles.

Further advantages include low water consumption, which reduces costs in terms of water, but also of chemicals that may be added; moreover, the cleaning medium can be re-circulated, and residual oils separated in the special collectors of the SR units. Therefore, no separate washing station with oil separator is required.

• Economics: Significantly less cleaning time, no or hardly any chemicals.

Overall: Comparatively low investment and hardly any running costs, but high efficiency and excellent quality.

PREVIOUS TECHNIQUE

In this specific application, retarder shafts were produced on a contract basis. The manufacturing process of these shafts included, after the actual machining, a tempering in oil as well as a downstream blasting with steel balls. The tempering oil hardened when the shaft cooled down and bonded blasting material to it, especially in the internal thread of the hollow taper.

Further cleaning was not carried out, as all the methods tested so far - cold wash table, washing machine, ultrasound - had not produced satisfactory results.

This led to very costly complaints and, in individual cases, to the return of entire semi-trailers full of goods. This problem is completely "off the table" with the introduction of our technology.

YOUR ADVANTAGES

• Efficiency/quality: Fast and thorough cleaning of the tempering oil in specific cases or of greasy and oily contamination in general. With the right spray accessories, even cleaning inside a component is possible without problems.
• Automation: Easy integration into semi- or fully-automated production processes.
• No damage: No damage to sensitive parts thanks to low pressure.
• Mobility: On-site cleaning – devices are mobile and self-sufficient.
• Occupational safety and environmental protection, chemicals: No or very little chemicals are required; this protects the environment, increases occupational safety and reduces costs.
• Universal applicability of the hot cleaning devices: These can be used for maintenance and servicing or for cleaning machines and parts.
• Economics: Significantly less cleaning time, no or hardly any chemicals.
• Overall: Comparatively low investment and hardly any running costs, but high efficiency and excellent quality.

REQUIREMENTS

Castings are made from a wide range of materials and in all conceivable sizes. Especially in the case of smaller units, accessibility to the inside of the body for cleaning is not readily feasible.

In these instances it is usually a matter of cleaning off fine chips from the machining process, including oil / cooling lubricant and the so-called casting sand.

PREVIOUS TECHNIQUE

Typically, compressed air is used in the hope of completely blowing out contaminants, or ultrasonic cleaning technology is used in suitably sized baths. Both alternative techniques are not considered reliable and are rather an attempt by the user to minimise complaints.

OUR SOLUTION

With the low-pressure hot cleaning method, excellent results are achieved in practice even when cleaning complex cast bodies. These can be ideally cleaned in the parts cleaning level of the devices of the SR family. Even hollows and interior spaces can be reached and rinsed out with the help of various nozzles, such as the flexible nozzle (see accessories), despite the difficult accessibility.

Compared to ultrasonic baths or washing machines, low-pressure hot cleaning is therefore a much more efficient and faster process that is also significantly more cost-effective. Thanks to the low pressure of up to 7.5 or 14 bar, damage-free cleaning is possible without any problems, even on sensitive components.

If necessary, alkaline cleaners with corrosion protection may be added.

In this particular application, tests were carried out at the customer's site, using cast bodies covered with a Makrolon sheet. Cleaning was demonstrated using a flexible nozzle SR-FX in the cavities of the cast body.

YOUR ADVANTAGES

• Efficiency: Contaminants are softened at up to 95°C and removed with minimal pressure.
• Time saving: This results in considerably shorter processing times and higher cleaning quality.
• Quality: Thanks to the flexible nozzle, even hard-to-reach areas, in this case even cavities, can be easily attained.
• Medium: Cleaning with water, if necessary with the addition of approx. 3% alkaline cleaner, or deionised water.
• Environment/chemistry: Therefore minimal use of chemicals, thus environmentally friendly and cost-saving.
• No damage to the workpiece, no rust formation.
• Increased safety at work: No risk of injury, no/low use of chemicals.
• Easy handling motivates employees.
• Economics: Low investment, low operating costs, high efficiency, and top quality.

REQUIREMENTS

In some processes, our equipment can be integrated into the process chain semi- or fully automatically. This is successfully used, for example, in the production of solar elements, flanges, connecting rods and in pipe cleaning, where robots are also used in some cases.

Tubes, for example, can be cleaned very effectively with the aid of a nozzle ring and a device from the 2000 series, which achieves a correspondingly high throughput.

The requirement for a high degree of automation in industrial parts cleaning does not necessarily imply the use of complex cleaning systems with high investments – in some cases it can also be realized in quite simple ways.

The components can be brought to the cleaning station via simple transport systems and, after cleaning, move on to the next processing steps. Depending on the geometry of the parts, the actual cleaning cell can be very compact.  

In a specific case, where connecting rods had to be cleaned in a series production, our unit was converted for continuous operation. The spray guns were replaced by ring nozzles actuated by a slow solenoid valve. The cooling lubricant of the machine tool was used for cleaning. This was circulated, with correspondingly optimum lubrication and corrosion protection properties and minimal costs for procurement and disposal.

Integration into the automation system was achieved by means of a simple control technology, whereby the cleaning device was integrated into the control technology of the system.

YOUR ADVANTAGES

• Efficiency/quality: Fast and thorough cleaning. With the right spray accessories, in combination with a robot if necessary, problem-free cleaning even of complex surfaces.
• No damage: Thanks to low pressure, no damage to sensitive parts.
• Extremely flexible thanks to various nozzles; can be used for all types and sizes of (metal) components.
• Simple conception ensures manageable investment with shortest realization time.
• Space-saving system that can be easily integrated into existing layouts.
• Full integration into existing parts transport system.
• Cleaning of parts also possible with cooling lubricant from the machine tool - thus optimum lubrication and corrosion protection properties.
• No splashback, no clouds of droplets, no aerosols; expensive housing can thus be avoided.
• Occupational safety and environmental protection, chemicals: Little or no chemicals required; this protects the environment, increases occupational safety and reduces costs.
• Recycling of process water via special sedimentation process and waste water filtration.
• Overall: Extremely low investment and hardly any running costs, but high efficiency and quality.

SEE ALSO

The video cleaning with robots shows how such systems could work in practice.

REQUIREMENTS

In this specific case, electrical connection parts made of brass, which are produced by machine tools with cutting oil cooled technology, had to be cleaned.

Large quantities - approx. 500-3500 pieces per shift - and different part sizes - L = 10-100mm, Ø = 2-50mm - had to be cleaned.

PREVIOUS TECHNIQUE

In continuous production, the workpieces are cleaned by hand in boxes next to the machine tools using petroleum and then blown off with compressed air.

OUR SOLUTION: LOW PRESSURE HOT-CLEANING AS ALTERNATIVE

With the help of low-pressure hot cleaning, the workpieces could be cleaned easily and considerably faster. Because of the high temperatures - up to 95°C - drying is much faster, so that (expensive) compressed air is saved. Thanks to the low pressure - up to 7.5 or up to 14 bar - the parts are not damaged.

In particular, expensive solvents that are harmful to health and the environment could be dispensed with.

In this particular case, no limescale stains remained on the surface. This could be solved, if necessary, with a stainless steel unit in which deionised water is used.

All in all, this resulted in a considerably faster and more cost-effective process, which also protects people and the environment.

YOUR ADVANTAGES

• Quality: Unimpeachable quality, no damage, no rejects.
• Efficiency: Significantly faster than manual cleaning (previous method).
• Environment/health/work safety/chemistry: No chemicals, therefore environment- and health-friendly, higher work safety, and significantly lower costs for working time and chemicals.
• Compressed air: Significant savings on compressed air.
• Universally applicable device: Ideal for parts cleaning, machine cleaning, automation.
• Economics: Low investment, low running costs, significant cost savings, and top quality.

REQUIRMENTS

Highly polished workpieces must be free of grease after engraving in order to be painted in a further step.

In the application, visible parts had to be cleaned that were integrated in a lift and in the operating surface.

PREVIOUS TECHNIQUE

In the particular application, it was almost impossible to clean the components because they were too large for ultra-sonic baths or clear rinsing baths; these methods were therefore not viable from a financial point of view.

Consequently, manual cleaning with rags was used. However, scratch-free cleaning was a particular challenge, as even soft rags left scratch marks.

OUR SOLUTION: MODIFIED 1000 SRE WITH SEPARATE RINSING SYSTEM

ph-cleantec recommended a modified 1000 SRE with a separate rinsing system.

The actual cleaning is done with alkaline cleaner and deionised water. The addition of alkaline cleaner reduces the aggressiveness of the deionised water; thus, a normal 1000 SRE could be specified instead of a stainless steel unit.

In a second step, the degreased area is rinsed clear with deionised water. This removes residues on the surfaces that cannot be removed later. This additional rinsing process thus generates a residue-free surface. The components can then be wet painted and installed.

YOUR ADVANTAGES

• Efficiency/quality: Low-pressure hot cleaning technology offers an ideal and efficient solution even for large components, saving time and avoiding rejects.
• Flexibility: Maximum flexibility with regard to quantities and sizes - no restriction to the dimensions of washing machines or ultrasonic baths.
• Cost-effectiveness: Until now, our customers were reluctant to sell highly polished versions because production and maintenance of the components were extremely costly and all residues were immediately visible. Since the introduction of our technology, this area has been highly profitable.
• All in all: Low investment, hardly any running costs, but high efficiency and perfect quality.

REQUIREMENTS

In the production of parts, components are often blasted with glass beads before coating in order to achieve optimum surface preparation with regard to adhesion and cleanliness.

In some cases, the glass bead residues adhere very strongly to the blasted parts and are difficult to remove. Especially in uncovered threaded holes and undercuts, glass bead residues can accumulate. If, for example, threads that are still contaminated with residues are then coated, the threads can no longer be used due to the residues trapped under the coating. The parts must be reworked or disposed of as rejects.

PREVIOUS TECHNIQUE

Previously, attempts were made to remove the residues by immersing the components in a solvent-containing liquid and then blowing out the parts with compressed air. This was only partially successful and led to relatively high reject rates.

YOUR ADVANTAGES

• Time saving/efficiency: Deposits on components can be removed from the components without residues and in the shortest possible time by using hot water. Time saving is often 80-90%.
• Quality: Even hard-to-reach places can be easily reached by using various spray tools (see accessories).
• Occupational safety and environmental protection/chemistry/costs: Use of harmful and expensive solvents is eliminated; therefore considerable cost reduction, and the entire disposal issue is avoided.
• Environmental protection/resources: Uses considerably less resources, including small amounts of water instead of large amounts of solvents. Process water can be recirculated for weeks, therefore also reduced waste water disposal.
• Mobility: Equipment is mobile, so cleaning directly "on site" is possible without any problems. This saves travel and reloading times.
• Efficiency: High temperature of up to 95°C contributes to fast drying of the workpieces.
• Additives: With suitable cleaners, the process can be used for iron phosphating and provides better corrosion protection through iron ions.
• Investment: Significantly lower investment costs compared to other processes.
• Universal usage of the hot cleaning devices: Also ideal for machine and parts cleaning in general.
• Economics: Efficient work, significant time savings and top quality, at the same time low investment and hardly any running costs.

AMORTISATION

Coating is usually the last production step before packaging and selling. If the almost finished workpieces have to be sorted out - after almost all other work steps such as (injection) moulding, turning, milling, threading etc. have already been carried out - this is highly undesirable and associated with comparatively high costs.

Therefore, our technology pays for itself within a very short time: Assuming scrap costs of only € 50 per part, a 1000 SR machine pays for itself after 130-150 parts less scrap.

Feel free to run a more precise calculation for your company numbers with the help of our amortisation calculator.

PREVIOUS TECHNIQUE

Large series are usually first degreased in immersion baths, then phosphated, and then dried with compressed air or hot air, often as part of fully automated processes.

For small series, on the other hand, this effort is not always worthwhile, and in these cases degreasing, phosphating and drying are usually done by hand. For degreasing, high-pressure cleaners are normally used with the appropriate chemicals, and this is carried out in special (and expensive) washrooms, oftentimes with appropriate protective equipment (protective suits).

As a result, three work steps - degreasing, phosphating and drying - are reduced to (more or less) one process step. Our customers regard this as a major competitive advantage for small series.

There are also considerable savings in chemicals: depending on the model, low-pressure hot cleaning devices have a throughput of up to 1.8 liters/minute (1000 series) or up to 2.8 liters/minute (1500 series), while high-pressure cleaners have a throughput of at least 20-30 liters/minute. To achieve the same concentration, the high-pressure cleaner thus requires at least 10 times the amount of chemicals. In addition, the cleaning medium can be re-circulated in low-pressure hot cleaning equipment, whereas this is often not the case with high-pressure cleaners. If the cleaning medium is circulated only 10 times, a high-pressure cleaner requires 100 times as much chemical as a low-pressure hot cleaning device - a massive saving given today's costs for chemical!

In addition, the ph-cleantec process is not only extremely cost-effective, but also particularly environment- and health-friendly.

YOUR ADVANTAGES

• Efficiency: Fast and reliable degreasing even of complex surfaces, corners and edges, bores, etc.
• Process reliability: All tests, such as drop test, salt spray test, cross-cut test, are passed without any problems.
• Working time: Fast and efficient degreasing. With the right cleaning agent, phosphating can be dispensed with - this saves working time and chemicals, and increases process reliability.
• Working time: WIth hot cleaning, large areas dry by themselves. Therefore, often only corners and lower edges have to be dried - this saves working time and compressed air.
• The result is three steps - degreasing, phosphating, and drying - in (almost) one!
• No damage to sensitive parts thanks to low pressure
• Highly flexible and suitable for all types and sizes of parts thanks to various nozzles.
• Low investment, especially for smaller parts; no need for separate washroom with corresponding underground systems. Minimal space requirements.
• No splash-back, no clouds of droplets, no aerosols.
• Occupational safety and environmental protection, chemicals: Little or no chemicals required; these can be recycled; this protects the environment, increases occupational safety and reduces costs.
• In summary: Comparatively ow investment and (significantly) low(er) running costs for chemistry and working time, yet high efficiency and process reliability.

REQUIREMENTS

Handguns consist of several components and need to be disassembled for cleaning. In the cleaning process mainly oil residues from preservation, residues of propellants, environmental dirt and the like need to be removed.

The geometries of the individual components are so complex and intricate that the weapon operator can only clean the components superficially using normal techniques. Especially for weapon overhauls in the police and armed forces, a professional and complete cleaning of the entire weapon is required. In this process, all weapon parts are examined for their suitability for use, wear, micro-fractures, etc.

Weapon components must of course also be cleaned during manufacture, for example barrels after honing.

YOUR ADVANTAGES

• Efficiency/quality: Due to high temperature and appropriate spray tools (nozzles), fast and thorough cleaning of even the "most impossible places".
• Fast drying of the individual parts or assemblies due to the high temperature.
• No damage to sensitive components.
• Cleaning inside the workshop is no problem: No aerosols, no VOC’s, no clouds of droplets, no splashback effects.
• Devices are mobile and generally self-sufficient.
• Occupational safety and environmental protection, chemicals: Only a small amount of chemicals is needed for temporary corrosion protection; this protects the environment, increases occupational safety and reduces costs.
• Hardly any waste water: Industrial water can be used in the cycle for up to 3 weeks. This saves chemicals and disposal costs.
• The hot cleaning units can be used universally, e.g. for maintenance and servicing or for cleaning machines and parts.
• Cost-effectiveness: Significantly less cleaning time; fewer chemicals and less waste water.
• Overall: Comparatively low investment and hardly any running costs, but high efficiency and top quality.

REQUIREMENTS

In the production of wooden trusses - which are mainly used as a static and visual element in building projects - a number of wooden boards are provided with a profile on their upper and lower sides and then glued together.

Wood glue is applied to the profile with the help of so-called glue combs, then hardener is applied with a hardener comb of comparable geometry. The tines of the glue combs apply the glue in very precise doses. The individual boards are then placed on top of each other by machine and pressed together. These combs are made of V4A stainless steel.

During production, the glue and hardener combs must be cleaned regularly, as they become clogged with drying residue (see left-hand area of the picture below) and can no longer apply the glue evenly and in an exact position.

OUR SOLUTION

So far, and in the absence of alternatives, the glue and hardener combs are cleaned either purely mechanically or with a high-pressure cleaner. Both cleaning methods frequently entail deformation of the tines. The resulting alignment effort leads to substantial time delays, and the glue heads need to be exchanged regularly.

Due to the low pressure and high temperatures, ph-cleantec was able to achieve excellent cleaning results very fast, and without damaging the tines. This was achieved using a 1000 SR and the cleaner 2022 HDF. The glue combs could therefore be made available again for production much more quickly. Both the glue and the hardener are acidic media that can be neutralised with the 2022 HDF.

YOUR ADVANTAGES

• Efficiency/quality: Much faster and very thorough cleaning of the glue combs, tines and nozzles. The high temperature of up to 95°C helps to liquefy the glue and hardener residues and thus to wash these off easily.
• Nonetheless, no damage to the tines due to low pressure
• High temperature contributes to very fast drying of the workpieces.
• Mobility: Cleaning on site - the devices are mobile and self-sufficient - saves assembly, travel and reloading times.
• Occupational safety and environmental protection/chemicals: Only very limited amounts of chemicals are needed; this protects the environment, increases occupational safety and reduces costs.
• The waste water situation is considerably alleviated, as process water can be used in the cycle for up to 3 weeks. This saves chemicals and disposal costs.
• The hot cleaning devices can be used universally, e.g. for maintenance and servicing or for cleaning machines and parts.
• Cost-effectiveness: Significantly less working time for cleaning, as well as assembly, travel and reloading times; fewer chemicals and less waste water.
• Overall: Comparatively low investment and hardly any running costs, but high efficiency and top quality.

REQUIREMENTS

Brass instruments are highly sensitive and are therefore cleaned almost exclusively by hand in a laborious and lengthy process. The various individual parts such as the valves and valve slides, mouthpiece and leadpipe, as well as all the curved parts such as the tuning slide, present particular challenges. Damage must be avoided at all costs.

OUR SOLUTION

The low-pressure hot cleaning process of ph-cleantec offers an excellent and highly cost-effective alternative. The low pressure of between 3 and 7.5 or 3 and 14 bar is sufficient to rinse even curved parts without any problems. The high temperatures of up to 95°C loosen and remove contamination.

With special nozzles such as the flexible nozzle or the needle nozzle, even interiors can be perfectly cleaned. Importantly, cleaning only takes a fraction of the time used when manual cleaning manually.

Equally important: Nothing is damaged and the process can take place inside the workshop without harming people or the environment. In addition, there is no need for (expensive and environmentally harmful) chemicals, as the cleaning effect is achieved through the high temperature.

The best way to see this for yourself is to watch the video of Lüttke Blasinstrumente in Volkerts­haus:

YOUR ADVANTAGES

• Efficiency/quality: Fast and thorough cleaning. With the right spray accessories, also easy cleaning of valves, curved parts, internal parts, etc.
• No damage: No damage to sensitive parts due to low pressure.
• Extremely flexible thanks to various nozzles; can be used for all types and sizes of brass wind instruments.
• Mobility: Cleaning inside the workshop – devices are mobile and self-sufficient, no major splash-back effects, clouds of droplets, aerosols, etc.
• Occupational safety and environmental protection, chemicals: No chemicals required; this protects the environment, increases occupational safety and reduces costs.
• Universal use of the hot cleaning devices: These can also be used for e.g. maintenance and servicing of other machines and equipment.
• Economics: Significantly time savings on cleaning, and no or hardly any chemicals.

REQUIREMENTS

A large number of filters are used in industry for a wide variety of applications: air filters, oil filters and hydraulic oil filters, grease filters, soot filters, mesh filters, expanded metal filters, electrostatic filters, fabric filters, baffle separators, lamella separators, demisters and stainless steel demisters, expanded metal mesh filters, and other filters up to and including air conditioning systems.

What they all have in common is that cleaning is often particularly challenging thanks to the complex and sometimes delicate surfaces on the one hand, and the usually very oily and stubborn deposits on the other.

Washing machines often do not reach the inner zones, and high-pressure cleaners would destroy the filigree surfaces. Many companies therefore outsource this task to third parties.
