Metal Powder Injection Molded Parts For Electronic Locks
There is a sufficient amount of chromium in the iron-based alloy to form a stable passivation film on the surface. Iron-based alloys with a chromium content of more than 10.5% can be called stainless steel. Stainless steel still has good oxidation resistance at high temperatures.

Process characteristics
1. Most refractory metals and their compounds, pseudoalloys, and porous materials can only be produced by powder metallurgy.
2. Because the powder metallurgy method can be pressed into a green compact of final size without or rarely requiring subsequent mechanical processing, it can greatly save metal and reduce product costs. When products are manufactured by powder metallurgy, the loss of metal is only 1-5%, while when produced by general casting method, the loss of metal may reach 80%.
3. Since the powder metallurgy process does not melt the material during the material production process, it is not afraid of mixing impurities brought by the crucible and deoxidizer, and the sintering is generally carried out in a vacuum and reducing atmosphere, which is not afraid of oxidation and will not give the material Without any contamination, it is possible to produce high-purity material.
4. The powder metallurgy method can ensure the correctness and uniformity of the material composition ratio.
5. Powder metallurgy is suitable for producing a large number of products with the same shape, especially for products with high processing costs such as gears. The production cost can be greatly reduced by powder metallurgy.
Stainless steel powder metallurgy parts processing flow
Raw material mixing → forming → degreasing and sintering → subsequent processing → finished product inspection
Mixing: Mix the required materials with a professional mixer and stir evenly
Forming: Press and form with a professional powder metallurgy forming machine and a special template (manufactured according to product design).
Degreasing sintering: control temperature and time according to different products
Subsequent processing: According to different parts requirements, the subsequent processing methods are different, including polishing, finishing, oil immersion, heat treatment, machining, etc.
Finished product testing: use different testing equipment for testing according to the product
