Almost all types of complicated 3D profiles can be manufactured by MIM technology. It provides designer the freedom to explore his/her imagination in designing complex components without worrying its manufacturability. All kinds of textures, serrations, threads (internal/external), fine holes, very thin walls (few millimeter), engravings are well within the scope of this technology.
Coring & Weight Reduction
Two or more semi-critical components can be combined into a single complex one – to be manufactured through MIM at one shot. This reduces weight of the total assembly thereby making it lighter; reduces total number of operations/processes; add direct value to the product – thereby saves time, money and efforts.
Quality control is the most important factor in any manufacturing process. When comes to quality, MIM has the edge over other conventional technologies like casting, forging, stamping or machining. MIM is the best technology for maintaining tight tolerances, repetitively. Once the process is set to the right parameters – dimensional accuracy with repeatability are automatic outcome of MIM. In general, the tolerances that can be achieved by this process is ±0.3 to ±0.5% of the basic dimension.
As on today, MIM is the best technology to produce large quantity of components (e.g. few millions/month) within very short period. It is the only technology that can handle 3D complex profile metal components with high accuracy in huge quantity.
Due to its homogeneous microstructure MIM components possess superior strength, high density when compared to other technologies like press & sinter, casting. Its mechanical & metallurgical properties are similar and sometimes better as compared to Wrought metal. Components produced by MIM are generally stress-free.
MIM is believed to be one of the most cost-effective manufacturing technologies for the requirement of most complex shaped miniature parts in high volumes. Generally, it can provide up to 40% cost savings as compared to other conventional manufacturing technologies.
Almost all types of steel and stainless steels are available in MIM. Engineered density material can be manufactured for weight critical components. In MIM it is much easier to create alloys that are not available in wrought form. Alloys of titanium & tungsten are very convenient to handle in MIM to manufacture net shape components.
