Our Company
Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. is a high-tech enterprise specializing in the R&D, production and service of metal powder injection molding (MIM) and ceramic powder injection molding (CIM). The company has a production workshop of more than 6,800 square meters and a production team of more than 230 people. It has a complete production system of design-mold
opening-batching-sintering-machining-grinding-polishing-assembly.
Our company can produce various structural parts, functional parts and appearance parts with complex three-dimensional shapes according to the needs of different customers. Products are widely used in 3Chh, lock industry, watch and jewelry industry, medical equipment industry, household appliance industry, automobile industry, communication product industry, etc. Based on the talent team graduated from the Department of Powder Materials, the rigorous and standardized control process is the basis for each Industry customers provide quality products.
Watch-case: protect the watch movement from foreign dust, liquid or shock damage or even damage, while providing a unique appearance for the watch. At present, the mainstream materials are 316 stainless steel and 304 stainless steel. Among them, 316 stainless steel (also known as fine steel) is the case material of mid-to-high-end watches, which contains molybdenum so it is corrosion-resistant. Mainly used in the food industry, pharmaceutical industry and surgical equipment, quality determines the grade, skin-friendly and low-sensitivity is very friendly to the human body. In addition, the case materials include 18k gold, silver, titanium alloy, etc., which are all excellent case materials;
Mold and Gage
1. Mold service life: usually semi-permanent. (except lost foam).
2. Mold delivery time: 10-25 days, (according to product structure and product size).
3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.
