Twin Screw Plastic Extrusion Sheet (PET) Unit & Multi-layer Co-Extrusion (PP, PS) Machine

Twin Screw Plastic Extrusion Sheet (PET) Unit:

• The main body used to produce PET sheet material, is a double screw extruder. With this, power consumption in drying pre-crystallized material can be reduced. Featuring high productivity low power consumption and excellent plasticization capability.

• The screw barrel adopting the blocking structure is mesh conjugated double-headed thread. Since its designed and optimized by computer and manufactured precisely, this component features excellent self-cleaning as well as interchangeability.

• The screw part of screw component is designed according to customers' material and process technique, it is optimized on the basis of experience in screw configuration research and design over the past several years, and upgraded with update software technology. Based on these, several functions with different needs can be realized, such as plastic transfer, mixed refining, shear&dispersion, and material filling in exactly in excess PET material.

• The cylinder is designed with a double vacuum exhaust path, to make ensure vapor and other volatile gas can be fully discharged.

• The extruder is equipped with a melt dosing pump to ensure the stability of output melt and voltage. Similarly, the pressure and speed loop is controlled automatically.

Advantage of total machine unit:

• The units with more than one extruder technology should be used for the production of multilayersheets such as PP, HIPS, PE. meet the needs of different sheets. Widely used in thermoforming, printing, hardware packaging.

• Single screw extruder sheet machine with a new type of screw structure, feeding stability, melting and mixing low melting temperature, high capacity.

• The whole machine adopts PLC control, realization of parameter settings, data and feedback. Automation control alarm function.

• Equipped with capacitance metering pump, precision multilayer distributor, flow with double blade gap, adjustment layered more evenly.
