Features That MIM Products Typically Have

MIM metal injection molding is a flexible process, and the annual demand of thousands to millions of output can be realized very economically. Like casting and injection molding, MIM requires customers to invest in mold and tooling costs, so for small batches, it usually affects cost estimates.

MIM can process many materials, including ferroalloys, superalloys, titanium alloys, copper alloys, refractory metals, cemented carbides, ceramics and metal matrix composites. While non-ferrous alloys of aluminium and copper are technically feasible, they are usually processed by other more economical means such as die casting or machining.

1. The complexity of metal injection molding products

Like injection molding, MIM has no restrictions on shape design. Since mim machining is a molding process, additional product features do not add cost, making MIM an ideal way to combine individual parts into multifunctional products. MIM design rules are so close to injection molding that they apply to almost any product.

2. Precision of metal injection molding products

Reference designs for MIM net shape accuracy are typically ± 0.5% of size. The net shape of some properties can reach ±0.3%. As with other technologies, the higher the accuracy requirement, the higher the cost, so moderate relaxation of tolerance requirements is encouraged when quality permits. Tolerances that MIM cannot achieve in one shot can be achieved with the help of surface treatments.

3. Weight and size refinement of metal injection molding products

MIM is particularly suitable for parts weighing less than 100 grams, with less than 50 grams being the most economical. However, parts weighing up to 250 grams can also be handled. The main cost of the MIM metal injection molding process is the raw material, so powdered metal injection molding companies use new technologies to reduce the weight of the parts as much as possible. As with plastic products, cores and brackets can be used to reduce the weight of parts without compromising product integrity. MIM excels in extremely small and micro components, and weights less than 0.1 grams are feasible. Weight is not a limiting factor and products longer than 250mm can also be handled.

4. Thinning of metal injection molding products

Wall thicknesses of less than 6 mm are most suitable for MIM. Thicker outer walls are also possible, but the cost will increase due to the long processing time and the addition of extra material. In addition, very thin walls below 0.5 mm can also be achieved for MIM, but have high requirements for design.

MIM metal injection molding is widely used in various medical, electronic, industrial, consumer and other industries. Metal injection molding product of mim china design includes auto parts, aerospace equipment, mobile phones, dental instruments, electronic heat sinks and sealed packaging, electronic connector hardware, Industrial tools, fiber optic connectors, spray systems, disk drives, medical equipment, hand-held power tools, surgical instruments and sports equipment, etc.
