Rubber Extrusion
Cold Feed Pin Type Extruder
for Processing Rubber Compounds
|
 |
Features of the RMS PME:
Screw
The screw is designed to ensure the highest output of compound with the lowest temperature, while maintaining homogeneous
extrudate.
Hopper
Wide hopper opening to handle wide feed strips. A liner with spiral undercut passages to ensure an aggressive feed. Feed roller is driven from the screw shaft and our special design ensures no contamination of the forward feed roll bearing. Hinged assembly for easy cleaning. Feed roller to prevent contamination.
Pin Barrel Section
The barrel is a steel fabrication. Liner is a replaceable bimetal liner. Pins are readily positioned in rows at a fixed pitch. 
Gear Reducer
The reducer is a fixed ratio vertically or horizontally arranged double reduction unit with a minimum of 1.5 service factor and supplied with an integral thrust bearing and lubrication system.
Extrusion Heads
Single and multiple cavity heads. Innovative design and manufacturing using CAD/CAM. Standard or custom designs available to meet product requirements. Single, dual, triple or quadruple compound heads.
Feeders
Automatic slab feeder complete with metal detector, safety reverse and interlocked with extruder. Available for 24" (600 mm), 36" (900 mm) and 48" (1200 mm) wide.
