Plastic and rubber extruders are industrial machines that melt and shape polymers through a screw or ram to produce continuous profiles, tubing, film, and pellets. They vary from single-screw and twin-screw designs to specialized co-rotating or counter-rotating configurations for compounding, blending, and venting. Common in plastics and rubber processing, extruders require precise temperature control, feed systems, and downstream equipment for cutting, cooling, and quality control.
Check screw and barrel wear, gearbox and motor condition, control panel functionality, heater zones and thermocouples, maintenance records, availability of spare parts, and compatibility with your tooling and raw materials.
Hire a heavy-equipment carrier experienced with industrial machines. Drain fluids, secure moving parts, skid and brace the machine, provide accurate dimensions and weight, and confirm crane or forklift access at both ends plus insurance.
Perform daily cleaning of the hopper and feed, regular lubrication, monitor motor amps and torque, verify heating control accuracy, inspect seals and screw wear, and schedule periodic gearbox and screw rebuilds.
