For many years Tencheng has been committed to the research, development and design of extrusion die and complete equipment of plastic machinery. So we take the leading position in the design, technology, craft, quality and output in this industry. Our products can be comparable with international brand-name products, and have been exported to many foreign countries.
Tengcheng has excellent management and design talents, new design level, advanced processing technic, high-quanlity craft equipment, precision testing instrument and all kinds of excellent large processing equipment. For example: 10000 mm high precision surface grinder, 10000 mm gantry type nc boring and milling machine, which can fully meet all kinds of plastic products within 10 m (including 10 m), extrusion die in the range of ply δ= 0.005-100 mm and complete equipment of plastic mashinery. Mainly fit for the manufacture of single-layer, double-layer and multi-layer of plastic materials like PVC, PS, OPP, PO, PP, PE, EVA, PC, TPU, PUB, PVUD, etc.
The extruder is mainly composed of barrel screw, gear transmission system, measurable feeding, vacuum deaerating, heating, cooling and electro control components, etc. It is mainly used in plasticizing, extruding and forming plastic plate, sheet, film, profile, pipe, pelletizing, etc.
The extruder fits for thermoplastic film, plate, sheet, bar, profile, pipe, plastic granulation for PP, PE, PS, ABS, PMMA, PVC and so forth. Adopt different length to diameter ratios and compression ratios in screw aiming at various raw materials and product specs. Adopt different structures in canister. Select suitable canister, screw and drive mechanism to satisfy processing requirements of high quality product.Characteristics: High yield, low consumption.Thermal processing and fine milling for each gear in reduction gearbox with hard gear surface, compelled cooling system to ensure efficient, low noise and long lifetime.Geometric parameters, reasonable structure, the screw has different ratios of length to diameter and structures aiming at various raw materials and products to meet customers’ needs.There are two structures, ditch groove and smooth section in heating section of material canister to meet the requirements of various raw materials.Adopt high performance alloy steel in screw, material canister, feature in wearable, anti-corrosion, high intensity and so on.Tight and reasonable structure, convenient operation, simple maintenance.
These series are mainly used to produce cast film (stretch film, wrapping film), and fresh-keeping film. The production of the film has viscosity on one side or both sides which can be widely used in packaging of building materials, hardware accessories, etc. The screw and its canister are made of 38 CrNoALA alloy and nitrogen processed. They are of high hardness, strong erosion resistance and endurance. Advanced automatic control system for temperature control, T type die adopts multi-point adjustment, so that ensures a more uniform thickness of membrane material. Recycled water cooling device supplies good cooling effect. Rolling device adopts the friction-type winding, and equipped with edge-cutting devices and remaining recycle device makes the film rolled more neatly.
