MIM Typical products And Application area

The development of Metal Injection Molding(MIM)industry was reviewed.The production methods of MIM powder and some typical MIM processes,which were the two chief fadors affecting the MIM industry of 21st century.

Aerospace industry: aircraft wing hinge, rocket nozzle, missile tail, ceramic turbine blade core
Automotive industry: ignition control lock parts, turbocharger rotor, valve rail parts, automotive brake parts, automotive sunblock parts
Electronic industry: disk drive components, cable connectors, electronic shell, computer print head, electronic packaging
Armory industry: mine rotor, gun trigger, armor-piercing projectile core, crosshair, cluster arrow projectile small arrow
Medical treatment: orthodontic brackets, internal suture needles, biopsy forceps, radiation shield
Daily necessities: watch case, watch strap, watch buckle, golf ball and tee, sports shoes buckle, sports gun parts, document binding puncher machinery industry: special-shaped milling cutter, cutting tools, micro gear
MIM requires fine raw material powder to ensure uniform dispersion, good rheological property and large sintering rate. Therefore, the price of MIM raw material powder is about 10 times that of traditional PM powder, which is a key factor limiting the wide application of MIM technology at present.The ideal MIM powder is powder size 2~8um, loose packing density 40%~50%, shaking density more than 50%;The powder particles are subspherical and larger than the surface.At present, the main methods of producing MIM powder include carbonyl method, high-pressure gas atomization method, ultra-high-pressure water atomization method, plasma atomization method, laminar flow atomization method and powder coating method.
