Zhoushan Dinghai Jinsheng Bimetal Plastic Machinery Manufactory specializes in the production of single- and twin-screw plastic machinery and its associated cylinders and accessories. Strong technical force, and equipped with advanced special equipment and strict testing methods. The product materials are first made of high-quality alloy structural steel 38CrMoAlA, refined by quenching, forming, qualitative, nitriding (or spray welding double alloy), fine grinding, polishing and other processes, so that our products have good wear resistance, resistance The advantages of corrosion and longer service life are the preferred products to replace imported screws. At the same time, in order to meet the different needs of the majority of users, the factory also provides screw and barrel remodeling design and real sample mapping, and can use dual alloy powder repair technology to repair worn screw and barrel.

We solemnly promise that we will provide quality and cheap products for our customers at home and abroad, in return for our customers' reputation and recognition.
