Reciprocating screw injection modules can be equipped with a choice of four plasticizing screws. All hydraulic functions except back pressure are controlled by on-off valves, meaning there are no sensitive servo controls.
A friction coupling connects the screw to the injection piston ensuring perfect alignment and easy screw removal and a patented position resolver ensures excellent shot-to-shot repeatability.

Machines customized for preform production may be equipped with two-stage injection units.

Distributed I/O

The injection control cabinet is mounted on the injection unit, eliminating the need for routing long cable bundles from the main controls cabinet.

Customization examples

• Multi-material injection, two-stage injection
• Increased injection speed and/or torque
• Custom screw geometries and shut-off nozzles
