Core technology of powder metallurgy
Powder metallurgy is a process technology that produces various metal powders and uses them as raw materials to manufacture various types of products through pressing, sintering, and necessary subsequent treatments. Various types of gears, sprockets, camshafts, bushings, structural components, and other products can be manufactured through powder metallurgy technology..
Production process
Powder metallurgy process
1.Product mold making
Our Kangtao company can accept various CAD, Pro-E, Solid Works, and AutoCAD drawing versions. We first analyze the drawings and then evaluate them based on the product requirements to complete the mold design and manufacturing.
2.Raw material powder mixture
Mixing is the process of mixing various required powders in a certain proportion and making them uniform into powder blanks. We will also directly purchase imported raw material powder products based on product performance.
3.Forming and pressing embryo blocks
The purpose of molding is to produce a certain shape and size of embryo block, with a certain density and hardness. The powder metallurgy products produced by our company are directly molded from the mold in one go, which is the compression molding used in pressure molding.
4.Sintering of green blocks
Sintering is a critical process in powder metallurgy technology. The formed compact is sintered to obtain the desired final physical and mechanical properties. Our company mainly uses multicomponent solid-phase sintering composed of two or more components.
5.Post treatment of powder metallurgy products
The treatment after sintering can be carried out in various ways according to different product requirements. Such as finishing, oil immersion, machining, heat treatment, and electroplating.
6.Finished product packaging and storage
