The casting film extrusion molding equipment mainly includes main machine and auxiliary machine. The main machine is called extruder, which is composed of extrusion system (screw, barrel), feeding device, etc. The auxiliary machine refers to the subsequent equipment matched with it. As the core of extruder, screw has a very important influence on the quality and output of extruder products. The main function of a screw is to transport materials, heat transfer plasticizing materials and mixing and homogenizing materials.
Our company specializes in developing and manufacturing high quality and high precision plastic casting film extruder screw barrel. We can customize single screw, double screw and multiple screw according to customer needs. We use high quality 38CrMoALA alloy steel, surface treatment process includes: Tempering, nitriding, chrome plating, spraying alloy, with wear resistance, corrosion resistance, high temperature resistance, low temperature resistance, long service life, excellent plasticization, large amount of extrusion and other advantages.
1. Free combination design can be carried out according to the requirements of customers to meet the different needs of customers and the market to the greatest extent.
2. Widely used, unique screw flow channel design, can be suitable for different materials.
3. Good cooling effect, stable product quality, high output. The thickness of the film can be up to 0.017mm-0.08mm(the international standard is calculated as 0.025mm).
4. With high speed, stable performance, environmental protection, energy saving and other characteristics.
