Twin Screw Compounding Extruder for Various Plastic Granules

The Introduction of Twin Screw Compounding Extruder

In the fast-paced world of plastic manufacturing, the demand for efficient and versatile equipment has led to remarkable innovations. One such technological marvel is the twin screw compounding extruder, revolutionizing the production of various plastic granules. Let’s delve into the intricacies of this advanced machinery and explore its applications, benefits, and the impact it has on the plastic industry.

The compounding extrusion process has been a cornerstone in plastic manufacturing, ensuring the uniform distribution of additives and materials.At the same time, the additives will change its original plastic properties, so that it has its own single plastic does not have properties.

For example,PP and GF glass fiber reinforced blending significantly increases the mechanical properties of the plastic (tensile properties increase from 20-30MPa of pure only PP to 65-90MPa, and bending strength increases from 25-50MPa to 75-120MPa , the flexural modulus increases from the original 800-1500MPa to 3000-4500MPa) Such excellent mechanical properties can replace engineering plastics ABS and ABS additive materials.

At the same time its heat resistance is better than ABS; some engineering plastics pass through coexistence with other materials compounding, it can be made into plastic alloy materials, which have better mechanical properties and lower costs, and can be used to replace metal alloys.  Traditional extruders played a crucial role, but the emergence of twin screw compounding extruders has elevated the game.
