Metal Injection Molding for Smart Wear, Consumer Electronics and IT Fields
The demand for small, precision, high-volume components has allowed MIM to flourish in the electronics industry. The electronics industry is a major user of metal injection molded parts. Our MIM process can produce smartphone camera housings, buttons, folding phone hinges and connectors with complex geometries.
Electronic devices continue to be miniaturized, requiring parts to become smaller, perform better, and cost less. This is where metal injection molding can bring its advantages.
Our non-magnetic material technology uses cobalt-chromium-molybdenum alloy F75 to produce hinges for folding screen mobile phones. It is thin, non-magnetic, has no interference with electromagnetic signals, is extremely corrosion-resistant, and has a bright appearance.
We use titanium alloy and 17-4PH stainless steel to injection mold the parts in the hinge of folding screen mobile phones. Folding screen mobile phones and other electronic products (such as laptops and smart glasses) require a large number of hinge-type parts, most of which have complex structures and high hardness. Injection molding technology is the best method for manufacturing such parts. The popularity of foldable screen mobile phones around the world has become an important driving force for the rapid development of the MIM industry in recent years.
We also produce injection-molded buttons for smart watches. The products have sufficient hardness and will not deform during repeated pressing. The appearance is comparable to stainless steel. We provide polishing, brushing, PVD and other surface treatment processes.
Our injection molded watch cases reduce the amount of machining and cost, and are suitable for materials that cannot be forged and are difficult to machine, such as titanium alloys. We can provide 316L, F75, G19, pure titanium, Ti-6Al-4V and other low-cost metal injection materials. Powder injection molded titanium alloy watches have a relative density of more than 99% after sintering, and can obtain an exquisite appearance through sandblasting, polishing, PVD and other technologies.
Comparison of the microstructure of 316 stainless steel materials made by forging (left) and powder injection molding (right) shows that powder injection molding materials can achieve a density close to that of forging materials, and have smaller grains, making them suitable for surface treatment technologies such as high polishing.
The precision gears we produce through micro-injection molding weigh only about 0.02g, making them very precise and micro. The mold has a maximum of 64 holes, and the hardness after heat treatment is greater than 35HRC. The production process is highly automated and strict anti-rust control is implemented.
MIM Supplier uses powder injection molding technology to produce mobile phone camera rings. The parts material isPANACEA stainless steel parts require CNC, in-mold injection molding, PVD and other sintering post-processing processes, so that parts with light weight, high strength, good corrosion resistance, and non-magnetic (relative magnetic permeability < 1.04) can be manufactured.
