For ease of online reference, this metal molding process can be abbreviated to MIM. Otherwise, metal injection molding refers to a powder metal process. This process is characterized by the forcing of metal feedstock under pressure into a tool cavity. One part will be going through a de-binding process. This gets followed by a sintering process. This is necessary in order to produce the high strength metal part required.
A tool cavity is created by utilizing two hardened tool steel dies that have already been machined into shape. The majority of metal injection molding parts will be produced from stainless steel alloys. Otherwise, it is not uncommon for so-called exotic materials like titanium to be used in the manufacturing process. The main advantage of this metal molding process is that intricate parts made from stainless steel or other materials can be produced when not possible to die cast or machine with ease.
One used material is widely used. It has a low cost and non-permeability advantage for those industries concerned with the manufacture of electronic goods. The material has outstanding characteristics, namely anti-corrosion, dimension control, machinability and cosmetic polishing features. It has finishing characteristics suitable for PVD plating, painting and sandblasting work. Another MIM material being used is popular for its positive performance ratios on tensile strength and hardness.
This feature will generally apply to the structural part of the machinery being worked on. The material is martensitic and can harden quite considerably after being given heat treatment. This material can be applied to CNC, polishing and painting work. To close, here is a memorable acronym. PANACEA refers to ‘protect against nickel allergy, corrosion, erosion alloy. By now, this nickel free material’s standout characteristics would be self-explanatory, not so?
