Rocket groups are located at the end of the injection screw and serve as the most important for the injection system. A rocket with suitable tolerances will ensure the correct and smooth operation of the injection unit.
Rocket Groups with Protective
Rocket groups are parts that are subjected to very high pressure and corrosion. In particular, the point where the rocket and the ring are in contact with each other is subject to very high corrosion. With the special welding of these zones, the service life of the rocket group gets 2-3 times longer.
