280T PVC Pipe Fitting Injection Molding Machine ZH-280

The ZUIHUI ZH-280 is a medium-large tonnage heavy-duty servo injection molding machine dedicated to industrial PVC production. Optimized for high-viscosity, corrosive and heat-sensitive PVC materials such as UPVC and CPVC, it is specially designed for mass production of large PVC pipe fittings, profile sections, anti-corrosion structural parts and large sanitary PVC products.Equipped with 2800kN high rigid clamping force and a large theoretical injection weight of 797g, the machine adopts a professional anti-corrosion and low-shear plasticizing system. The hard chrome-plated corrosion-resistant screw and barrel effectively prevent PVC decomposition, carbonization and yellowing during molding, and resist erosion from corrosive gas. The upgraded plasticizing torque ensures uniform melting of high-viscosity PVC materials and flawless surface quality of large products.With customized servo closed-loop precise control system, it realizes gentle and stable adjustment of temperature, pressure and speed, perfectly matching the sensitive molding characteristics of PVC. It effectively eliminates common defects such as shrinkage, voids and stress cracking. Featuring large mold capacity, stable mold movement and reliable low-pressure mold protection, it supports long-term high-load production of complex large PVC molds.Widely applied for large-diameter PVC pipe fittings, electrical conduit parts, industrial anti-corrosion plastic components and PVC profile products, ZH-280 serves as a flagship dedicated machine for high-stability and low-defect mass production of medium and large industrial PVC products.
