Whether you're designing a single component or integrating a complete product line, JINXIN can provide you with engineering solutions that deliver the best performance levels for your blended applications. Blown film special screw
product description.

The blown film special screw enables the extrusion of the material melt at a lower temperature. The material is well homogenized by the shear action determined in the isolation gap. The melt plasticization process is controlled, that is, only particles smaller than the isolation gap can enter the melt channel.

Product advantage blown film special screw

The bolts are optimized by a separate screw and mixing element. The barrel is optimized with a grooved barrel and an extended feed section. Through the combination of a split screw and a grooved barrel, the following advantages can be obtained: the melting process of the material is optimized to increase the extrusion yield. The extrusion of the material melt at a lower temperature is achieved. The material is well homogenized by the shear action determined in the isolation gap. The melt plasticization process is controlled, that is, only particles smaller than the isolation gap can enter the melt channel. It provides a wide range of processing for different materials and is suitable for various polyolefin raw materials, especially suitable for HDPE, PP, ABS pipe raw materials.
