Two Stage Twin Screw Extruder Machine Price Plastic Extruder For PVC
Screw Kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material. Screw component made of high speed & wear-resisting steel.
By means of the replaceable screw barrel sections, the processing sections is devided into individual zones. The barrels are heated electrically. In addition, the barrels are provided with longitudinal bores for cooling with water. Uniform temperature distribution, namely on the circumference of the eightshaped barrel bore, is achieved by a reverse forceflow temperature
control circuit. Connections of pipes for temperature control are
in groove-tongue design to balance alternating thermal stress and avoid leakage.
1.The first stage is a parallel co-rotating twin-screw extruder with sufficient mixing function to realize the plasticization, mixing and homogenization of the material, and there is no back-pressure reflux of the head, so as to achieve the best mixing state of the materials.
2.The second stage is a single-screw extruder with low speed rotation, which can achieve the extrusion of material insulation and avoid decomposition in overheating processing.
3.According to the characteristics of materials and process, it has higher production efficiency and productivity.
4.It is suitable for the processing of all kinds of heat sensitive materials, such as PVC, XLPE, LSHF flame retardant cable material, high mineral powder filling, shielding material, etc.

Extensive heat and mass transfer, narrow residence time distribution, large surface to volume ratio, continuous operation. Ideal for high viscosity, high temperature reaction systems.
Continuous polymerization or reactive extrusion like dynamic vulcanization, crosslinking, grafting, and chain extension of PUR, PA, POM, PEI, PC, PMMA, PBT, PPS, etc.
Product Description: According to appearance design, it can be divided into close barrel, open barrel and venting barrel. According to the liner, it can be divided into integrated barrel (without liner) and with liner barrel. Diameter: 12-350mm Material: Company adopts imported HIP process of powder high speed steel, and precision CNC machining of the cylinder is adopted to make its accuracy level, wear-resisting and corrosion resistance be consistent with the origin first-line brand abroad; Cost performance is superior to the similar imported products.
