The Rewa technology expanding piston sealing machine seals the Rewa piston cleanly into the wax bed of the cartridge without lateral movements thanks to a calibration developed in-house. This ensures that the wax slides smoothly when the cartridge is emptied and at the same time guarantees the best possible seal during storage and partial processing. The Rewatechnik expanding piston capping machine places the piston into the filled cartridge with the required pressure, it is not susceptible to contamination and works practically wear-free, which means that the additional costs of the systems compared to competitor products are quickly offset. The only wearing part is the expansion ring, which has to be replaced after approx. 250,000 sealed cartridges. The "Rewa expanding piston and capping system" has proven itself millions of times over. Be it with aluminum cartridges or stainless steel cartridges. It can be integrated both in the laboratory and in complete filling lines. Depending on the viscosity, the cartridge sealing machine can be installed horizontally or vertically.
