One is high-strength structural parts: our factory can produce according to customer's product performance.
Powder metallurgy structural parts refer to metal powders as raw materials, which are pressed, sintered at a high temperature of 1120 degrees, shaped and immersed in oil. Anti-rust treatment. Compared with the traditional machining process, it has the following advantages:
① When the parts have irregular shapes, protrusions or pits, and various special-shaped holes, powder metallurgy is easy to manufacture, and no or only a small amount of supplementary cutting is required. obvious economical.
② When using powder metallurgy to produce other mechanical parts, the material utilization rate can reach more than 99.5%.
③Because the parts of the powder metallurgy process are produced by molds, the consistency of the contour, shape and size of the parts is very good, but there are many variables in various aspects when machining, and it is difficult to maintain consistency.
④ The powder metallurgy process can integrate several parts, which can save the cost of processing and assembly later. ⑤ The material density of powder structure parts is controllable and has a certain amount of connected pores. Generally, 5%-20% of lubricating oil is immersed in it to provide a certain degree of self-lubrication, thereby improving wear resistance.
⑥ Powder metallurgy structural parts can also be subjected to various follow-up treatments such as coating and heat treatment like mechanical parts.
