JIEHUANG China MIM parts manufacturer is mainly engaged in the production of (metal powder injection molding) precision metal parts and the provision of related solutions. The MIM products can be divided into two categories: precision metal structural parts and appearance parts, including power support parts, volume support parts, camera brackets, Structural parts such as threading sleeves and plugs, as well as delicate-looking power interface parts, smart watch cases, smart ring inner shells, drone remote control shaft brackets, headset accessories and other external parts.
The main application terminals of JIEHUANG MIM parts include tablet computers, smart touch capacitive pens, smart wearable devices, aerial photography drones, etc. Among them, smart wearable devices are growing rapidly. In addition, the company’s MIM products also include USB charging interface shells, annular cavities for 5G base stations, and automotive shift knobs, etc. The product services and application fields continue to expand to the automotive and 5G fields.
MIM has obvious advantages over traditional metal forming processes
MIM (metal powder injection molding) is a near-net-shape technology that combines traditional powder metallurgy technology with modern plastic injection molding technology. It is mixed into a uniform feed, and then injected into a mold to form a green body, and then the green body is subjected to degreasing treatment, and then sintered to densify the metal powder, and finally the finished product is formed.
Post-processing technology: including shaping, metal processing and surface treatment (including PVD, CNC, laser engraving, sandblasting, polishing, grinding, etc.), of which the company can make self-made processes including shaping, sandblasting, grinding, and CNC.
Inspection: The inspection contents include size inspection, appearance inspection, deformation inspection, etc. Common defects include concave points, multiple materials, gaps, defective door panels, crushing injuries, etc.;
Core technology: At present, the MIM China industry has not achieved batch automatic detection. The core reason is that the downstream demand iteration speed is too fast. If automatic detection equipment is used, the frequency of replacement or parameter adjustment is too high.
MIM metal injection molding process has the advantages of unrestricted structure, high product precision, and low cost.
For complex parts, traditional metal forming is usually to first decompose and make a single part and then assemble it. MIM process is more economical through overall processing and simplification of processing procedures.
Moreover, the cost of traditional metal forming increases as the complexity of the parts increases. The metal injection molding companies keeps the cost unchanged by increasing the complexity of the mold. The higher the product complexity, the more economical the MIM process and the more obvious cost advantages.
