conical twin-screw and barrel
Detailed Product Description
Conical twin-screw and barrel is the very kind of screw specialized in direct extrusion of various types PVC powder. With the unique advantage of screw core cooling, vacuum exhausting, good self cleaning, easy laying-off, easy maintenance and low energy consumption, conical twin-screw and barrel can meet the technical requirement of material delivery, compression, mixing, exhausting and plasticization at a lower temperature. As a result, it gradually took replaced single-screw equipment in PVC field and was already broadly applied in PVC processing fields.
However, the increase of CaCO3 proportion when processing PVC products and appearance of new type of PVC material, led to the result of deficiency in anticorrosion, wear resistance , plasticization quality and output of conical twin-screw and barrel. According to the clients different requirement ,Jnha people designed the best configured screw by introducing the most advanced design concept of twin screw-thread, twin screw depth and twin conicity to achieve the best plasticization status and the biggest output. Jinhua people also introduced the internationally advanced heat-treatment equipments and technology to solve the problem of wear and corrosion of conical screw and barrel. Conical twin-screw and barrel is already successfully applied in the process of PVC sheet, pipe, sheet, pellet and mould, etc. Whats more, it successfully solved the technical problem of various low foaming, high foaming, high filling, wear and corrosion, etc.
Advanced production equipment are adopted is to ensure that all screws are machined with special high-accuracy numerical control screw milling machine as well as interchangeability.
