MIM(Metal Injection Molding) introduction
MIM(Metal Injection Molding) is a forming method by injecting the plasticizing mixture of metal powder and binder. It can be consisted of 4 steps:
1, Mix the powder and binder, and then pelletize the mixture;
2, Injection molding;
3, Remove the binder to get the 100% metal parts;
4, The last is sintering.
Some sintering products may need to do further densification processing, heat treatment and machining. Sintered products not only have the same complex shape and high precision as plastic injection forming, but also have similar physical, chemical and mechanical properties as forged parts.
This technology is suitable for mass production of metal parts with small shape, precise and complex 3D shape, and has special performance requirements.
Application of MIM:
Metal powder injection molding has been widely used in mechanical
industry, electronic industry, automobile
industry, office automatic industry, watch, photoelectric
industry, medical devices etc.
1) Computers and auxiliary facilities: printer parts, core, striker
shaft pin, drive parts
2)Tools: such as gun drill, drill chuck, power tools, hand tools,
wrenches and other spare parts, milling heads, nozzles, etc.
3) Household appliances: such as watch case, bracelet, electric
toothbrushes, scissors, fans, golf head,
simulation jewelry,
tool heads and other parts;
4) Medical equipment parts: dental orthopedic frame, orthopedic bracing parts, scissors, tweezers;
5) Electrical parts: such as micro-motor parts, electronic parts,
sensors, cell phones etc.
6) Mechanical Parts: complex parts such as small loose cotton,
textile machines, sewing machines,
office machinery, and other machinery parts;
7) Automotive, marine parts: clutch inner ring, radial inserts,
fork sets, distributor cover, car airbags, car locks;
8) Oil drilling with various special-shaped carbide nozzles.
Commonly used materials for MIM process and their application fields:
