For 310 ml + 150 ml standard cartridges, robust and powerful, very high efficiency, good ergonomics thanks to the rotating cartridge frame, black rod with a very hard surface, push block with 6000 N pressure resistance, integrated ladder hook suitable for tough substances, transmission ratio 18:1. With printed empty cartridge
Improvements:
Pressure/punching at the end of the rod as a "stop". When the cartridge is empty, the "STOP" marking triggers the relaxation of the cartridge press. The cartridge press is thus automatically relaxed when the cartridge base is reached. Overloading/deformation/breakage of the press is therefore impossible.
The rod relaxes due to the built-in spring at the end stop. The push rod can be pulled back/relaxed without any effort.
Painting of the press when assembled. This has the following advantages: the swing of the trigger lever (left - right) is better controlled during production; no risk of the lever jamming (due to the color strength in the axis opening).
