1. Economical production of high-precision components
- The basic process is simple; metal powder is packed and then heated.
- The material yield is good thanks to the fact that the base materials are powders, thus making it an environmentally friendly method of production.
- High-precision molds mean that near net shape production is possible for relatively complex shapes, which in turn means not much post-processing (such as machining) is required for this method of production.
- Complex 3D shapes that it has conventionally not been possible to produce using powder metallurgy can be manufactured using a new technology called metal injection molding (or “MIM”).
- We undertake mass production of high-precision ultra-compact products with a manufacturing capability that incorporates all process from mold design onward.
- We also take a proactive approach to production using new MIM technology and were very quick to start mass production in Japan and Taiwan.
2. Products that are impossible with other methods can now be produced
- Production using molybdenum, tungsten, and other metals with high melting points is possible.
- It is possible to produce materials with any ratio of metal and nonmetal.
- Combinations of metals that do not melt into each other are possible.It is possible to make porous products.
- Sintered oil-impregnated bearings make use of these characteristics and are impregnated with lubricating oil.
- On the basis of our 60-year devotion to powder metallurgy, we can select the best material for the way our customers intend to use a product, and ensure the product meets our customers’ needs.
- At Porite, we developed our own oils for use in our sintered oil-impregnated bearings, and our ability to combine materials and oils to suit the intended use of a product is something that other companies simply cannot match.
