Technical Highlights

● Our screws and barrels are made of nitride alloy steel (38CrMoALA) with excellent performance. After thermal refining, qualitative, nitriding, quenching and tempering, the hardness reaches as high as 67-72HRC., wear resistant, anti-corrosion, high strength, good toughness, and excellent plasticizing performance. The barrel is equipped with a cooling fan and a cast aluminum heater, which has high thermal efficiency, fast and uniform heating speed.

● Equipped with a quantitative feeding system, frequency conversion speed control.

● The screw is professionally designed, and the mixing effect and plasticizing effect are good. On the bigger-end of the screw, the heat capacity is large, the screw groove is deep, the contact area between the material and the screw and the barrel is large, and the residence time is longer, which is good for the heat transfer. On the smaller-end of the screw, the residence time of the material is short, and the linear speed and shear rate of the screw are low, which is good for reducing the friction heat between the material, the screw and the barrel.
