Why is MIM injection molding better than die casting?
Metal injection molding (MIM) is a high cost and efficient production molding technology for precision and complex parts at present. It not only has high production efficiency and good production quality, but also has low batch production cost. Therefore, compared with the traditional casting process, the production cost is more cost-effective. There are many differences between MIM and casting in material, molding method and temperature. Now, Dongguan Zhenglang Powder Metallurgy Factory will share with you the reason why MIM is superior to die-casting molding.

1. Higher temperature: high temperature treatment, iron base and copper base sintered alloy
powder metallurgy
2. More corrosion resistance: copper based sintered alloy and sintered stainless steel can meet the requirements of powder metallurgy and die casting. Under the condition of using temperature not exceeding 65 ℃ and required medium strength, zinc die casting can replace iron base metal injection molding MIM products.
3. High tensile strength: the tensile strength of some iron base metal injection molding MIM sintered alloys is more than three times that of die-casting alloys.
4. High wear resistance: iron base and copper base sintered alloys containing lubricating oil can solve the problem of high wear resistance and high antifriction performance.
It is more appropriate to use metal injection molding MIM technology to produce precision and complex precision parts, stainless steel parts, and alloy parts, with greater production cost advantages and higher cost performance ratio. At present, 90% of precision small parts use powder metallurgy molding technology to obtain MIM parts. Precision and complex parts are also suitable for mass production.
