metal injection moldingMIM is developed from the integration of traditional powder metallurgy technology and modern plastic injection molding technology. , wax and other materials) are evenly mixed to make a feed with rheological properties, which are injected into the mold cavity (or multiple mold cavities) through an injection machine to form a part blank. After the blank is removed from the binder and sintered at high temperature, Various metal parts with uniform microstructure and highly dense materials can be obtained.
The electronic instrument industry is the main application area of MIM parts, accounting for about 50% of MIM parts sales in Asia. The miniaturization of electronic devices requires the production of lower-cost, better-performing, smaller parts, which is where MIM parts come in handy.
In the 1990s, the most widely known application of MIM was the tungsten alloy vibrator of the vibration motor of the BP machine. After 2000, stainless steel series began to be widely used, such as fiber optic connectors, hinge series of consumer electronics, mobile phone buttons, sim card trays, etc. The recent investment boom in the MIM industry is due to the wide application of MIM components in the mobile phone industry and the lowering of investment thresholds, which have attracted a large inflow of capital.
Fiber Optic Parts
The thin-walled (wall thickness less than 1mm) and complex-shaped optical fiber transceiver cover made of 17-4PH stainless steel is an ultra-high-speed transceiver parallel optical module used in network and telecommunication equipment. These thin walled MIM enclosures are supported by 4 thin struts supporting 2 parallel strips.
Other typical electronic industry MIM products
MIM products are also commonly used in the electronics industry such as disk drive components, cable connectors, electronic packages, cell phone vibrators, computer print heads, and the like.
