Our Custom Coating Solution masters these challenges
- To improve the handling, the coating chamber door opens sideways; the opened chamber door can be swiveled by 90° so the loading and unloading can take place from the left-hand side
- The coil is arranged at a certain angle to the deposition technology to ensure a constant coating thickness distribution
- The LGD® (Lateral Glow Discharge) process is used for etching and improved coating adhesion
- To guarantee a uniform coating, the teeth and the back of the saw band are coated by different cathode types
- The coating process takes place at a maximum temperature of 500°C to ensure that the physical and chemical properties of the saw band remain unchanged
- Coating increases the lifespan of saw bands and improves the cutting performance during sawing; the development of tool wear is reduced
In order to meet the product-specific requirements of WIKUS, we designed a turnkey system with a PVD coating unit operating at a high vacuum as well as a tailor-made single-chamber cleaning system. The saw bands are wound as a coil and are both cleaned and coated with the same product carrier to avoid additional effort.
The Pi603 is the first PVD coating unit for WIKUS. It was built in 2006 and is still working perfectly today. Our design proved to be very user-friendly. Even Customers who are not experienced with such technologies can operate this unit with ease. Pursuant to the open-source principle, we transferred our knowledge to WIKUS. This enables WIKUS to benefit from the advantages of LARC® cathodes and flexibly combine as well as develop its own coatings.
