complex shapes: MIM and CIM allow for the free design of three-dimensional shapes like injection molding. Since MIM and CIM are a molding process, the additional product shape does not increase the cost. If weight reduction is achieved by shape design, the cost will decrease, which makes MIM and CIM ideal for combining more than one individual part into a multi-functional part. One of the ways. MIM and CIM design rules are very close to injection molding, making it easy to adapt to three-level complex metal parts.
Dimensional precision: The near net netting accuracy of MIM and CIM is usually ±0.5% of the size. Some dimensional features can reach ±0.3%. As with other technologies, high precision means higher cost, so it is recommended to moderately relax the dimensional tolerances if it can be used. Tolerances that MIM and CIM cannot directly satisfy can be achieved by subsequent processing.
Thin-walled products: Wall thicknesses of less than 6 mm are suitable for MIM and CIM. A thicker outer wall is also possible, but the process time will increase a lot and the material cost will increase. Thin walls below 0.5 mm can also be achieved with MIM and CIM, and Fuchi Hi-Tech can achieve 0.2mm extremely thin-walled products (but have a certain dependence on the shape of the specific product).
Weight: MIM and CIM are suitable for parts weighing less than 100 grams, and less than 50 grams is the most common application. However, parts weighing up to 250 grams can also be used in MIM and CIM processes. Raw materials are a key cost factor for MIM and CIM processes. The early stages of MIM and CIM product design tend to minimize the weight of components. As with plastic products, the weight of parts can be reduced by the core and bracket without compromising product integrity. MIM and CIM are outstanding in terms of extremely small and micro-components, and weights of less than 0.1 gram are also possible. Products with a length of more than 250mm can also be achieved.
Batch size: For MIM and CIM products, mold and pre-product development processes are required for MIM and CIM processes, so for small batches of products (less than a few thousand pieces per year), it usually affects decision making. process. MIM and CIM can be realized very economically from a small production of tens of thousands of pieces per year to a production of tens of millions of pieces. Fuchi Hi-Tech has undertaken a number of MIM and CIM products with annual requirements of over 10 million pieces.
Wide range of raw materials: MIM can handle many materials, including ferroalloys, stainless steel, copper, KOVAR alloys, superalloys, and hard alloys.
