Extruder Drive Gear Reducer Thrust Assembly Feed Throat

Digital DC, AC vector or brushless DC drive systems available for all polymer applications. Connected to gear reducer via fully guarded matched belts and sheaves allowing interchangeability to meet different torque and speed requirements.

Double reduction parallel shaft helical reducer with generous mechanical and thermal ratings. Self contained splash type oil bath.

Heavy duty cylindrical roller type bearings mounted in a separate thrust housing with its own oil bath which does not allow any cross contamination with the gear reducer.

High density class 40 iron casting jacketed for water cooling. The large rectangular feed hole is tangetial to the bore, which has a pressed fit removable bimetallic liner. A powder seal is fitted in the rear of the feed throat. A high capacity hopper complete with sight glass and dump chute is included. An optional dual shutter magnet box is also available.

Barrel Heating & Cooling Barrel Base

Screw

Processing control achieved via cast aluminum heating elements, each zone individually shrouded to guide cooling air directly over barrel elements. Cooling air provided by externally mounted blowers. Liquid cooling via closed circuit cooling pump system optionally available.

Centrifical cast bimetallic lined barrel, base material 4140 or JP38 tube steel, precision machined taper grip flanges threaded and welded for added strength. Designed for maximum operating pressures of 10,000 PSI. Optional superior corrosion, wear resistant and vented barrels available.

Heavy duty structural steel base provides for exact alignment between all plastification components. Extruder components including motor control panel and transformer pre wired in a compact unitzed package for easy component accessibility and minimal installation time. The front barrel support is heavy duty weldment with horizontally inserted dowl pins allowing for linear barrel expansion. The adjustment feature of the front barrel support allows for precise barrel alignment.

Single stage metering type, base material pre hardened 4140, chrome plated, colmonoy hardened flights, and optional coring for cooling. Special performance designs engineered to suit individual applications for superior outputs and melt quality available including barrier type and special mixing sections.

Control Cabinet Clamp

Base mounted control panel containing microprocessor based temperature controllers, circuit breakers, ammeters, load contactors, and control transformer for each barrel and die zone. The drive operator keypad station containing the following; speed regulation, start/stop, screw speed indicator, load indicator as well as other drive data and fault indicators which are remote mounted near head on operator side. A die heating stepdown transformer is included. Power requirements 460/3/60 standard, 230/3/60 or 575/3/60 available.

Three piece taper grip clamp with single swing bolt fastening capability provides positive seal and alignment between barrel and die flange. Two piece double hinged swing bolt design and adjustable hinged die support optionally available.

Optionally Available

Deltatech PLC-based touchscreen extrusion control system with multi microprocessor control, PID temperature control, closed loop speed control, direct access menus, full drive synchronization capability, alarm diagnostics, and RS232 communications.
