This laboratory twin screw extruder operates efficiently with adjustable speeds ranging from 0-280rpm or higher, catering to different processing needs. The screws are made from wear-resistant alloy steel (W6Mo5CR4V2) and chromium-molybdenum alloy tool steel (40CrNiMoA), ensuring high hardness (HRC60) and superior wear resistance.
Enhance your extrusion processing with the laboratory twin screw extruder, designed for high precision and durability.
Applications
The laboratory twin screw extruder is ideal for:
- Mixing and plastification of engineering plastics, modified plastics, recycled plastics, and masterbatches
- Homogenizing plastics, color sampling, and filling modification
- Extrusion processing experiments for various polymer materials

The mandrel is made of 40CrNiMoA chromium-molybdenum alloy tool steel, while the threaded components are made of W6Mo5CR4V2 wear-resistant alloy steel with a hardness of HRC60. The screw includes conveying blocks, mixing blocks, shearing blocks, banburying blocks, kneading blocks, countercurrent blocks, and modular building block components. The mandrel is connected with a gradually splined design and can be configured according to any material ratio to meet the needs of various extrusion processes. - Combination Method
The screw assembly follows a modular block-style design, and the machine barrel is composed of multiple sections, featuring a self-cleaning function. - Heating Zone
The barrel has 5 cast aluminum heaters, while the handpiece has 1 heater. Each heating section has a power of 1 kW, and the external parts are covered with a safety protective wind hood. - Cooling Zone
The entire barrel is equipped with a soft water circulation cooling system. Each section’s water flow rate is adjustable, and it includes a self-priming circulating water pump, a 304 stainless steel water storage tank, inlet and outlet water pipes, and electromagnetic valve components. This setup allows independent temperature control and cooling for each barrel section. - Electric Control System
The system uses a PLC programmable color touch screen, man-machine interface operation system, with dynamic display and monitoring of the extrusion process. It includes functions for temperature control, driving, speed, pressure, and interlocking intercontrol. - Power supply
AC380V, 50Hz, 3-phase 5-wire
