The company covers an area of 80000 square meters and is a professional manufacturer of screws and barrels. Jinhai Screw Products was founded in Through more than 30 years of practical innovation and the unremitting efforts of two generations, our products are distributed throughout the country, and our quality and service have received widespread praise from both internal and external manufacturers. Our company meets the needs of both internal and external customers with a new business philosophy and technological equipment. The company mainly produces various injection molding machine screws, material barrels (nitriding, bimetallic spraying), various chemical fiber extruder screws, material barrels, various plastic single screw extruder screws, material barrels, various conical twin-screw, material barrels, various parallel twin-screw, and material barrels. Over the years, our company has adhered to a customer-oriented service attitude, continuously pursued product perfection, continuously innovated, gradually reduced management costs, and taken the path of a professional and service-oriented enterprise, with the Jinwei and JinHailuo logosChuangzhong, Haopin, and various screw barrels are made of high-quality alloy steel 38CrMoALA. After negative ion nitriding, the products have high wear resistance, corrosion resistance, and improved service life. Screw types: gradient type, mutation type, wave type, double screen type, cone type, diversion type, separation type, exhaust type, pin type, multi variant type, hybrid type, double head, triple head, multi head type, granulation type, etc. The compression ratio of the barrel screw can be designed according to different products and formulas.

　　Screw type

　　Length to diameter ratio: L/D=15-60

　　Screw can be selected according to different plastic products, and different screw compression ratios, length to diameter ratios, and barrel shapes can be designed according to different raw materials and products, with different exhaust systems and IKV forced feeding systems.

　　Applicable plastic range: PVC

　　PP

　　PE, PO, PPU, PU, OPP, PC, ABS, PA, PET, PPR, EVA, PPS, PBT and other plastic extrusion molding, EPE pearl cotton foaming, and various waste plastic recycling pellets.

　　Machine barrel screw, different types of screws are selected for different raw materials, with high output and good plasticization. The material of the barrel screw is forged 38GrMoAlA, which has been quenched and tempered, normalized, and precision processed before gas nitriding treatment. Depending on the different raw materials, alloy powder can also be sprayed on the inner wall of the barrel and the surface of the screw. It has a long service life and good wear and corrosion resistance.
