What is metal powder injection molding technology?

With the development of metal powder technology, more and more industries apply metal powder to metal powder, which has promoted the metal powder forming technology to receive widespread attention. However, as the metal powder industry is an emerging science and technology field, most people do not know the metal powder forming technology. Today, I will explain what the metal powder forming technology is. Metal powder molding technology, the full name of metal powder injection molding technology, is a new fine powder refining and molding technology formed by the modern plastic injection molding technology entering the fine powder refining field.

This mold is mainly used for injection molding of blank, and rapid manufacturing of high-density, high-precision, three-dimensional complex shape structural parts through sintering, which can quickly and accurately materialize design ideas into articles with certain structural and functional characteristics, and can directly produce parts in batches, which is a new revolution in the manufacturing technology industry. Generally speaking, we can understand metal powder forming technology as mold compression, but it mainly uses metal powder materials. The equipment required for metal powder injection molding includes: granulator, MIM special injection molding machine, degreasing furnace, sintering furnace, testing equipment, secondary processing equipment, etc.

Metal powder injection molding can be divided into two types: stamping molding and special molding. Special molding is the process of compacting metal powder into blanks with certain shape, size, density and strength. It is one of the basic processes of fine powder extraction. Before metal powder forming, the general powder pretreatment must meet the requirements of forming and mixing, and a certain amount of powder forming additives must be added. Powder compression curing is also known as powder molding. Through continuous improvement in the design of the press, press and mold used to press various oil bearings, fine powder refining antifriction articles, powder) gold and other mechanical structural parts, the four-axis hydraulic press can press out parts with complex shapes, with a high degree of mechanization and automation.

The special solidification of metal powder is used for occasions with special requirements for the shape, size and density of the blank. There have been powder cold isostatic pressure solidification, powder rolling solidification, powder extrusion solidification, powder slurry casting and powder explosive solidification, which can produce high-precision, irregularly shaped articles and thin-walled parts.

It should be noted that these equipment can not be produced casually. It has very high technical requirements. Therefore, it can not be used by any equipment that produces metal powder injection molding. When purchasing equipment, pay attention to the use of equipment to meet your own needs! In a word, the future development of metal powder injection molding is mainly the efforts on materials and design. Therefore, the current cooperative customers who need can use the advantages of technology to help customers improve the product design, reduce costs, and expand the application field of metal powder injection molding.
