For Sale - PCM - 3234 - Extruders

The Extruders base is fabricated out of mild steel plates, channels, the top of the base is machined to mount hopper block and barrel support bracket. The AC induction motor and reduction gearbox are accommodated on the base. Barrel cooling blowers are all accommodated inside the base.

The screw and barrel are made from special alloy steel. Barrel and screw are nitride hardened, fine polished and chrome plated. Screw is specially designed for LLDPE material. The function of the screw is to carry the material from hopper to die with homogeneous melt. For precise control of temperature the barrel is divided in to 5 zones. Thermocouples fitted on the barrel and Pyrometers on control panel are for monitoring and controlling of the temperatures in each zone. Die zone is mounted on die head for precise control of temperature of die head.

Barrel blowers are provided to maintain barrel temperature accurately. Finned cast aluminum shells grip the cast heating element and effect quick cooling. Water-cooling jacket is provided in hopper block. Water circulation in the jacket is necessary, for the safety of thrust bearings.

Thrust housing is constructed robustly from cast iron to hold the barrel horizontal. Barrel is fitted with heavy flange with high-tension bolt. It is having three bearings. One additional bearing is to withstand thrust pressure during extrusion. Seals are provided for restricting the entry of raw material in the housing.

Main drive is AC motor with heavy-duty gearbox connected through V belt and sturdy coupling.

Die head fixed with flange, Breaker-plate are duly hard chrome plated.

Water cooling tray is fabricated in SS 304. Sufficiently long and leak proof. Tray is mounted on stand guide rollers are provided to guide the strands traveling from the tray. Outlets are given at the bottom to drain the water.


Control panel is constructed in MS CRC sheet. Panel is powder coated in Siemens gray color. All switchgears are of Siemens make. Volt meter with voltage selector switch for incoming voltage. Temperature controllers with thermocouple, ammeter for each zone. Detail circuit diagram along with catalog specification and rating for each item.
