What are the forming technologies for powder metallurgy processing?

At present, powder metallurgy processing is used in many fields. By using various copper based, iron based, alloy and other materials as raw materials, pressing or injection molding, and then sintering and post-processing, it can form a variety of desired complex and heterogeneous parts, which can be produced and processed in large quantities with high efficiency, especially for some complex precision parts and batch production. Do you know what kinds of forming technologies are commonly used for powder metallurgy processing? Here is a brief introduction of the Zhongwei Precision Editor:

Powder metallurgy processing

Forming technology of powder metallurgy processing:

1. Press Forming Technology (PM)

Powder metallurgy pressing forming technology (PM) is known as a new forming technology to solve high-tech and new materials. The products formed by pressing have the advantages of high performance, high precision, low cost, mass production, etc. MIM/PM is currently the focus of research and development in the powder metallurgy industry. In practical industrial applications, it is the most widely used one. Cold closed steel mold pressing, cold isostatic pressing, hot isostatic pressing and warm pressing all belong to pressing forming. However, some complex structural parts cannot be produced or can only be made into preforms because they can only be pressed up and down in both directions.

2. Metal Injection Molding (MIM)

Powder Metallurgy Metal Injection Molding (MIM) is a new powder metallurgy near net shape forming technology, which introduces modern plastic spray forming technology into the field of powder metallurgy. It breaks through the limitation of traditional forming technology, and can not only form complex parts in large quantities and with high efficiency, but also has less processing technology, no cutting or less cutting, higher product performance, and easy forming. It has become a prominent forming technology for modern manufacturing of high-precision precision parts. It not only inherits the advantages of traditional powder metallurgy and plastic injection molding, but also breaks through the limitations of traditional metal powder molding on part shape. It can rapidly manufacture parts that are small in size and complex in shape and cannot be processed or difficult to process by traditional methods.

The content introduced above is the molding technology of powder metallurgy processing. Powder metallurgy has replaced the traditional molding and processing methods in various fields. The application of its powder metallurgy molding technology in various fields can better improve the performance of products, reduce processing costs, and produce complex precision parts in large quantities, which is a new revolution in the manufacturing technology industry.
