Classification of Forming Technologies for Powder Metallurgy Processing

At present, powder metallurgy processing is being used in many fields. It uses various copper based, iron based, alloy and other materials as raw materials, and then undergoes compression molding or injection molding, followed by sintering and post-processing to form various complex and heterogeneous parts. It can be produced and processed in large quantities with high efficiency, especially for some complex precision parts and mass production. Do you know what are the commonly used forming technologies for powder metallurgy processing? Let's introduce to you:

Forming technology for powder metallurgy processing:

1. Press Forming Technology (PM)

Powder metallurgy pressing and forming technology (PM) is known as a new type of forming technology that solves high-tech and new materials. The products formed by pressing have advantages such as high performance, high precision, low cost, and mass production. MIM/PM is currently an important research and development of two forming technologies in the powder metallurgy industry. It is widely used in practical industrial applications. Cold closed steel mold pressing, cold isostatic pressing, Hot isostatic pressing, and warm pressing are all pressing forming. However, due to the ability to press both up and down, some complex structural components cannot be produced or can only be made into blanks.

2. Injection Molding Technology (MIM)

Powder Metallurgy Injection Molding (MIM) is a new powder metallurgy near net forming technology that introduces modern plastic spray forming technology into the field of powder metallurgy. Breaking through the limitations of traditional forming processes, it is not only able to form complex parts in large quantities and with high efficiency, but also has fewer machining processes, no cutting or less cutting, higher product performance, and easy forming, becoming 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 in part shape. It can quickly manufacture parts with small volume and complex shape that cannot be processed or difficult to process using traditional methods.
