Threaded-body cylinders

Double-acting threaded-body cylinders are used when the return stroke must be effected in a certain time, e.g. with clock-pulse-controlled devices.
Of course they can also generate pulling forces.

These double-acting cylinders allow a space saving installation into the fixture body and therefore a hosefree oil supply. The double-wiper protects the piston and enables sealing with very little leakage. Sealing of the cylinders in the fit hole is made by two O-ring / support-ring combinations. Tightening of the cylinder can be made by a pin-type face spanner as per DIN  3116, so the collar can be immersed into the device, if necessary.

Injection mould

Cycle (portrayed in simplified terms):

1. Mould closed, substance injected
2. Threaded-body cylinder (5) moves out of the mould
3. Mould opens (the slide operates, the nozzle is free)
4. Workpiece will be removed from mould
5. Mould closes
6. Threaded-body cylinder (5) moves into the mould
1. New cycle
