New design Zwergle-Duo Special for Storopack, the world's leading system supplier and service provider for flexible and tailor-made protective packaging (72 locations in 18 countries):
- 2 rotating turntables with universal holders for 2 chamber doctor blades up to 1250mm long
- 2 Tank system: Clean with alkaline cleaner
- Rinse with high pressure pump
- each tank with thermostatically controlled heating
Special challenge:
Since the customer requested that no solvent-based cleaner be used, greater mechanical effort was required:
- an additional (water) tank for rinsing after cleaning
- Additional tank heating to increase the cleaning effect of the alkaline cleaner
- more complex controls

Further development of SMT stencil cleaning systems:
After intensive testing, we have raised our SMT stencil cleaning systems to a new level in terms of cleaning time:
By using an extremely powerful washing pump with 160l/min in combination with our pat. Spray arms, the pat. Docking device for standard 25l plastic cleaning agent canisters and a fine filter, our systems are now able to create metal stencils in approx. 3 minutes. to be cleaned of solder residue and glue!!!
To our great surprise, this even works with “stretched” cleaner from KIWO (mixing ratio 60% cleaner, 40% water)
Thanks to our design, the cleaner heats up to 25 °C in approx. 30 minutes during washing mode (without heating!!)
At short notice, we demonstrate the performance of the system on site with your templates* and your operating resources.
(*Note: stencil size 555x555mm!)
After the system has been delivered, it can be inspected by our customer, who already has 12 of our systems in use, by making an appointment

- Program Sequence:
- Open lid with foot switch
- Equip the system with rollers (position by position)
- Close the lid with the foot switch
- Press start button
- The drive for the rotation of the rollers starts
- The wash pump conveys the cleaner from the buffer tank to the spray arm and cleans the rollers for an adjustable period of time, the cleaner flows back into the buffer tank
- After the set cleaning time, the draining time begins
- After the adjustable draining time, the 3-way valve switches (washing tank/high-pressure water tank), the high-pressure pump conveys the hot water from the buffer tank to the mobile high-pressure nozzle assembly and cleans the rollers (first position 1, then 2, then 3 > depending on the program selection). The water flows back into the buffer tank*
- After the high-pressure cleaning, the roller is blown off with compressed air via the mobile nozzle assembly (first pos. 1, then 2, then 3)
- After blowing out, the 3-way valve switches again (high-pressure water tank/washing tank)
- program end
* After an adjustable cycle time, the high-pressure water tank is partially emptied via a solenoid valve and automatically refilled. This saves a lot of fresh water and requires far less energy to heat the water.

Our latest project: parts cleaning system for
Task:
Cleaning of Porsche deep-drawn parts in a continuous process (system length max. 3m, belt speed approx. 1500mm/min), which come coated with adhesive oil directly from a 1600t-Schuler press.
After intensive tests with cleaners and solvents from countless manufacturers, we found that this approach would not lead to success.
The cleaner simply ran off the deep-drawn parts without any effect. Only after a longer exposure time, which unfortunately is not available to us in the continuous system, success was shown.
Based on our findings, we found a solution without the use of cleaners to largely remove the adhesive oil from the parts. We are also developing a simple oil separation device.
Of course, we submitted this solution to the patent attorney!!
November 2022:
The raccoon 2.0 SMD stencil cleaning system is now only supplied with rinsing.
Through intensive testing, we were able to increase the performance of our washing pumps from the original 70l/min to 160l/min.
In the future, all SMD stencil cleaning systems will have the self-priming washing pumps with a capacity of 160l/min!!!, of course in combination with our dockable 25l canisters (protected for use!!).
With this combination, the cleaner heats up by 8°C within 10 minutes during the washing process !!
In addition, the new generation raccoons have 20" stainless steel filters to ensure the higher flow rates and pressures.
