What are the criteria for choosing a MIM technology?

The process technology, materials and equipment of MIM technology have become more and more mature in China and its application range is very wide. The advantage of MIM technology lies in its complex shape, small size and large output. These advantages of MIM technology enable it to be widely used in electronic digital products, light weapons, MIM intelligent wear, hand tools, MIM communication medical treatment, MIM auto parts, electronic seals, cutting tools and sports equipment.

So, how do you determine whether a product should choose MIM technology, which is the criteria for choosing MIM technology?

The following is the introduction of the new material by daihong. The following are the main points to consider before choosing the MIM technology:

1. Quality and cutting quantity: the discovery of new materials of dahong has an advantage in reducing production cost for the parts with very high material loss and time consuming in cutting and grinding.

2. Total demand: for the products with low demand, the mold fee and r&d fee can hardly be borne after they are Shared. Therefore, MIM industry leading manufacturers suggest that MIM technology should be considered when the annual demand for products reaches or exceeds 20,000 units.

3. Materials: MIM technology is a near-clean forming technology, which is most attractive for parts designed from difficult cutting materials such as titanium, stainless steel and nickel alloy.

4. Product complexity: MIM technology is most suitable for manufacturing multi-axis parts and multi-reference parts, such as powder metallurgy miniature gear, powder metallurgy small module gear and other precision and complex parts with complex geometric shapes that need to be changed many times during machining.

5. Performance: MIM experts have found that the high density of MIM materials is based on. If the performance is required, the performance of the high density of MIM products will be competitive

6. Surface roughness: the surface roughness reflects the size of the original powder particles.

7. Tolerance (precision requirements) :The tolerance of nonfat sintering parts in MIM technology is about + / -0.3%. If the product requirements are strict, MIM sintering parts need to be reprocessed, such as CNC and CNC vehicles. The cost of MIM materials tends to increase and needs to be evaluated and compared.

8. Combination: in order to save inventory and assembly costs, multiple parts can be consolidated into one.

9. Defects: defects inherent to MIM technology must be kept in a non-critical position, or can be removed after metal powder injection molding, such as gate marks, thimble marks or binding lines.

10. New composite materials: MIM technology can produce new composite materials that are difficult to be manufactured by traditional processes, such as laminated or mixed metal-ceramic materials with two material structures or wear resistance, such as MIM ceramic case.

There are many types of materials commonly used in MIM technology, but several are the main ones. If the material is difficult to cut, such as tool steel, titanium, nickel alloy or stainless steel, for powder metal injection molding, MIM technology can be used to form complex geometric shape features at one time. The performance achieved with MIM technology varies between production locations.

Now, dahong new materials have seen a lot of new materials designed for MIM, including laminated structures (hard magnetic - soft magnetic, magnetic - non-magnetic, conductive - insulating), foamed metals and holes newly constructed, and these optional projects are pushing MIM technology into areas where there is almost no process alternative.
