SJZ型锥形双螺杆挤出机适用于各类PVC粉料挤出成型的专用设备，配备不同的模具及辅机可以生产各类PVC塑料管材、异型材、板材、片材、棒材及造粒。.

  螺杆采用油冷却系统冷却。机筒采用特殊风冷系统冷却。系统采用专用电脑控制。根据用户不同配方要求，配置结构合理螺杆，以达到塑化状态及物料质量。螺杆全部采用高精度专用数控螺杆铣床加工，可确保每台同类挤出设备挤出性能高度一致性。率先引入国际先进变螺距，变深度螺杆设计技术，使物流在螺杆中剪切、压缩更柔和，更接近实际需要。分配箱特殊设计，推力轴承格外加大，轴承采用原装进口，传动寿命高，可承受更大挤出压力。电器系统大限度采用进口原件，并具有多项故障报警功能，故障少，排除方便。冷却系统设计特殊，散热面积格外加大，冷却迅速，温控精度可达±1℃。

SJZ Conical Twin screw extruder is application for different kinds of PVC powder material extrusion, with different mould and downstream equipments, it can produce pipe, profile, plate & sheet, and pelletizing

Screw designed with oil cooling system, barrel use air cooling, with specialized computer system. According to different material and formula, we provide the most suitable screw geometry to achieve optimized plastization and premium quality of end product. All twin screw processed by CNC, this assures the constant performance of all extruder under the same series. First use the changeable flight distance and changeable channel depth technique to make the shearing and compressing more tender Special design for transmission box, equipped with imported bigger trust bearing，give a longer service life and higher pressure load to the transmission system. Electrical elements use famous international brand, less fault. Special designed cooling system, increase the radiation area, fast cooling and temperature controller tolerance less than 1°C
