Injection unit

ENGEL LIM injection units

ENGEL LIM injection units are available both in execution with conveying screw and with injection piston. Special check valve types permitting immediate and accurately repeatable closing are used with both sys-tems, The check valve, in combination with the accurate dosing, is a prerequisite for reproducible shot weights.

ENGEL LIM-screw injection unit

Due to the better feeding effectiveness of the screw, screw injection units are recommended for high viscosity LSR materials. Screw injection units are also used for smallest shot weights.

The double plunger injection unit for large shot volumes

Due to the shorter cycle times, the smooth processing and the excellent physical properties of LSR, this material is increasingly used for the manufacture of large-volume moulded products. With the ENGEL LIM-double plunger injection unit volumes up to 10.000 cm3 can be processed economically. Each of the two liquid silicone rubber components A + B is directly supplied into the double plunger injection unit.
