Compounding With The Twin Screw Extruder

PURUI company make and design Twin-screw extruders are used for mixing, compounding and processing of viscous materials and are used in a variety of polymer applications. The twin screw extruder machines are used for the plastic extrusion process when two or more ingredients are mixed or compounded. The twin-screw extruder is well established in the plastics industry due to its flexibility, which allows for testing of different polymer formulations to obtain the desired results. When using the twin screw for compounding rubber and plastics, ingredients can be added such as fillers, antioxidants, and light stabilizers. The recipe of ingredients should be designed to allow the powder to run flood feed. This takes advantage of the twin screw extruder’s constant pump machine and achieves better dimensional control of the finished parts.

There are different variations of twin screw extruders to suit the application. They can be classified by the shape and the direction of rotation, co-rotating or counter rotating, of the two screws. The shape of the twin screw extruders can be parallel or conical. The two screws in a parallel twin screw extruder have the same diameter through out the length. They are used to process polymers such as nylons, polyolefins (PE, PP) and polyesters. The conical twin screw extruder diameter is higher at the feed end and smaller at the die end and are generally used to process PVC. Twin screw extruder is particularly useful in the production of rigid PVC and wood fiber blends.

including the incorporation of additives using the twin screw extruder. Please feel free to contact us, we are look forward to hearing you.
