Extruder Machine SME Screw Element And Barrel Double Screw Extruder Parts Mixing Zone

Product Description

The SME screw element is a hybrid element with several reverse shallow return grooves on a conventional forward conveying element. When the material is transported, multiple strands of backflow are formed through the many shallow grooves on the spiral edge, and the ability to disperse and distribute is added. This element generates low shear heat, and the SME screw element has the lowest energy consumption of several screw mixing elements. Selection principle: It is usually placed in the melting section and the extrusion section of the twin-screw, and it is arranged between the 45 ° or 60 ° kneading blocks in the overall low-shear overall pattern of the full-screw to appropriately increase the distribution and dispersion of the melt.

Quality Control

1). Materials control: All the materials are purchased from the domestic brands or European twin-screw specialty materials suppliers, which tested by elemental analysis and metallurgical inspections to ensure the quality.
2). The internal splines is checked by the spline plug to ensure interchangeability of the elements
3). All components are machined by CNC machines to ensure the shapes and tolerances of the elements
4). Adopt the European high-speed steel powder processing technology, and do the treatment according to the strict heat treatment 4 process to ensure the wear and corrosion performance same as the foreign brands.
5). Professional technical team can not only provide timely and accurate mapping sample design but also the combination of elements of technical services.
6). There are various prepared technical information and the fixtures for the various brands extruders to ensure the timely lead time. The common components have a lot of stock, even the new one, it can be delivered within 45days.
7). The modern management system can ensure the products 100% qualified and tracked.
