Metal injection molding (MIM) enables mass production of complex shapes. It is a method suitable for mass-produced items with intricate designs.
This is an introduction to Metal Injection Molding (MIM). It is a method suitable for mass production of complex shapes with product weights of approximately 10g to 20g. (When exceeding 30g, it tends to be more cost-effective to perform additional processing on precision cast products.) The method offers high freedom of shape, allowing for sharp edges, irregular holes, and three-dimensional shapes. We can accommodate quantities starting from several hundred pieces per lot. We specialize in small quantities of diverse products. Please feel free to consult with us. 【Features of Metal Injection Molding (MIM)】 ■ High dimensional accuracy can be achieved. ■ Surface roughness is approximately Rmax 8μm, and it is possible to achieve sub-micron surface roughness with processes like glossy barrel finishing. ■ Heat treatment and surface treatment equivalent to that of melted materials are possible. 【What is Metal Injection Molding (MIM)?】 It is a method that combines the technologies of plastic injection molding and metal powder metallurgy. It achieves mechanical strength close to that of melted materials, which cannot be obtained through powder sintering. Metal powder is injected together with resin to form the shape. After that, solvent debinding is performed, followed by vacuum sintering. At this stage, the product dimensions shrink, requiring expertise and experience.
