Best MIM machining parts corrosion test process and characteristics

time:2020-04-26Views:964 Author:Best Seiko
MIM machining parts are often used in our surroundings, and its arrival brings great convenience to our lives. The main reason for its popularity is corrosion resistance. Today Best will introduce the corrosion test of MIM processing to you. The corrosion test can be simple by immersion test. One of the corrosion tests applied to one of the MIM machined stainless steels was to immerse the sample 5 in 10 55 mm (0.4 0.4 2.2 inches) at room temperature in a 2% sulfuric acid solution for 1000 hours. However, it is faster to rely on a 6-minute immersion in copper sulfate solution to check for copper plating or other attacks (ASTM F 1089). Other tests of corrosion include 30 to 180 minutes (ASTM F 1089) boiling water immersion. An effective test, commonly used but not standardized, is to sinter parts immersed in chlorine-containing bleach and observe discoloration within one minute. Shenzhen Best Precision Technology Co., Ltd. is a diversified technology company integrating metal injection molding, metal and ceramic 3D printing, and metal jewelry development and production. Best Precision has reached a strategic cooperation with well-known domestic and foreign feeding companies (Kadem Feeding) and BSF for MIM product development and production, mainly for metal powder injection molding, metal powder injection molding, powder injection molding, powder injection molding, Metal 3D printing wire, metal powder injection molding factory, metal powder injection molding factory, powder injection molding factory, powder injection molding factory, MIM process, MIM processing, MIM factory to provide customers in various industries around the world with large quantities, high quality and reasonable MIM products at a price. The company has assembled a team of senior experts in technology, management and market development in the industry, adhering to many years of MIM technology experience and industrial production operation experience, with internationally mature MIM technology, efficient supply chain management and rapid and effective large Large-scale manufacturing capabilities provide customers with a one-stop solution from the preliminary design, sample development and mass production of MIM products. Introduction of MIM processing technology: Metal powder injection molding technology is a product that intersects and intersects with plastic molding technology, polymer chemical powder metallurgy technology, metal technology and metal material science. Sintering quickly produces high-density, high-precision, three-dimensional complex-shaped structural parts. The process technology not only has the advantages of less conventional powder metallurgy process steps, no cutting or less cutting, and high economic benefits, but also overcomes the traditional powder metallurgy process products with low density, uneven material, low mechanical properties, difficult to form thin walls, and complex structures. Disadvantages, especially suitable for mass production of small and complex metal parts with special requirements! Technical characteristics of metal powder injection molding: 1. Can produce parts with complex three-dimensional shapes, avoid multiple machining. 2. Product appearance finish can reach 0.5 ~ 1.6um 3. Product weight range 0.1 ~ 250g 4. Dimensional accuracy can reach ± 0.1 %-±0.3% 5. The relative density of the product can reach 95% to 99%, the mechanical properties are high, and the corrosion resistance is good 6. The thin-walled products can be manufactured, and the thin ones can reach 0.2 mm 7. The products can be post-treated (turning, infiltrating) Carbon, quenching, tempering, electroplating, polishing, PVD, wire drawing, laser engraving, etc.) 8. Parts can be manufactured in large quantities at low cost
