Scope of application for planetary screw barrel
For good plasticizing effect,we have different designs of planetary screw barrel to meet customer's demand.Our factory manufactures with high-quality material, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
The company adheres to the customer as the center, to strictly control the quality of the production process, the implementation of lean production management to ensure that the quality of the testing process continues to be effective, excellent product quality. To meet the requirements of different customers with efficient production capacity and timely delivery capacity. The company has many years engaged in the design of plastic machinery parts, processing of professional personnel, and can provide customers with door-to-door mapping, design, transformation, custom, and other services, and to undertake all kinds of wear and tear of the repair work.
We are a professional manufacturer of screw barrel.
Our company implements scientific management, well equipped with different kinds of advanced processing and inspection equipment. This provides a solid foundation for our quality products.
