Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. specializes in the production of metal injection molding parts. The company has long-term strategic cooperation with domestic Yongyao, Desheng, Sanming and other rotary hook production international companies such as Japan's Zovin rotary shuttle, and Italy's Simon and other enterprises. Metal injection-molded hook case, material After joint research and efforts with Central South University, the products produced by the company not only have good wear resistance, but also have high hardness. Each year, Desheng supplies 600,000-800,000 hook cases, and 10 other manufacturers. -300,000 bobbin case supply.
Process advantages of metal powder injection molding
1. High degree of design freedom: Compared with other metal forming methods, MIM can manufacture more complex parts. Basically all structures that can be realized by injection moulding can be used on MIM.
2. Wide range of applicable materials: MIM is almost suitable for most metal materials. Considering the economy, the main application materials include iron-based, nickel-based, copper-based, titanium-based metals or alloys.
3. Excellent physical and chemical properties: Since the sintered density of MIM is very close to the theoretical density, its physical and chemical properties are also very good, such as mechanical strength, which greatly surpasses traditional powder metallurgy.
4. Exquisite appearance: The surface roughness (Ra) of the MIM sintered blank can reach 1 μm, and a dazzling appearance can be obtained through various surface treatment methods.
5. High dimensional accuracy: MIM can generally achieve a tolerance accuracy of ±0.5%, and with other processing methods, higher dimensional accuracy can be obtained.
6. Strong mass production capacity, flexible and changeable: MIM can be adjusted flexibly to rapidly increase the output, from hundreds of tablets per day to hundreds of thousands of tablets per day, with rapid response.
7. The processing concept is environmentally friendly: the utilization rate of raw materials is close to 100%, which is a near-net-shape technology, which can effectively avoid material waste.
