Merits of powder metallurgy technology:
1. Requiring non or little cutting process,
2. The utilization rate of the material is up to 97%,
3. The production tolerance of accessory size is relatively small making it repeatable,
4. Material composition is adjustable,
5. Accessory's surface is fine and smooth,
6. Its strength and abrasion resistance can be enhanced through heat treatment,
7. For self-lubricating or filtrating, materials or products with controllable porosity are affordable,
8. It can produce fancy accessories with complicated shapes, which cannot be produced using other shaping processing methods, It's suitable for medium to mass production of accessories.
