Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. is an industry in which metal powder or metal powder (or a mixture of metal powder and non-metal powder) is used as a raw material to produce metal materials, composite materials, and various types of products after forming and sintering technology. At present, powder metallurgy technology has been widely used in the fields of transportation, machinery, electronics, aerospace, weapons, biology, new energy, information, and nuclear industries, and has become one of the vigorous branches of new material science. Xinghua powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision, and good stability, and is very suitable for mass production. In addition, some materials and complex parts that cannot be prepared by traditional casting methods and machining methods can also be manufactured by powder metallurgy technology, so they have attracted the attention of the industry.
Advantages of Precision Powder Metallurgy Process
1) No or only a small amount of machining is required;
2) The material utilization rate is high, up to 95% or more;
3) The size of the parts is consistent and stable; the accuracy can reach 0.01MM!
4) The material composition can be adjusted according to the performance requirements of the customer's parts;
5) The surface of parts can be treated according to customer needs to improve strength and hardness;
6) Due to the use of mold forming, it can produce complex or strange-shaped parts that cannot be produced by other cutting processes;
7) Since Shaped PM sintered parts are suitable for mass production, the production efficiency is high and the cost is lower than cutting processing.
Powder metallurgy processing flow
1. Stainless steel powder metallurgy parts processing flow:
Raw material mixing → forming → degreasing and sintering → subsequent processing → finished product inspection
Mixing: Mix the required materials with a professional mixer and stir evenly
Forming: Press and form with a professional powder metallurgy forming machine and a special template (manufactured according to product design).
Degreasing sintering: control temperature and time according to different products
Subsequent processing: According to different parts requirements, the subsequent processing methods are different, including polishing, finishing, oil immersion, heat treatment, machining, etc.
Finished product testing: use different testing equipment for testing according to the product
Processing route map of iron-based powder metallurgy parts:
Raw material mixing→forming→dewaxing and sintering→subsequent processing→finished product testing
Mixing of raw materials: Mix the required materials with a professional mixer and stir evenly
Forming: Pressing and forming with professional powder metallurgy forming machine and special template (manufactured according to product design)
Dewaxing and sintering: control temperature and time according to different products
Subsequent processing: According to different parts requirements, the subsequent processing methods are different. The specific methods are as follows: polishing, finishing, blackening, oil immersion, machining, heat treatment, electroplating, finishing, repressing, refiring
Finished product testing: use different testing equipment for testing according to the product
