Application of tungsten alloy in the field of metal injection molding


With the development of society, the technology of various industries in our country is developing rapidly. Powder injection molding technology is a molding technology that has only been developed in recent years. Its application in metallurgical fields such as insoluble tungsten alloys has a certain effect. , Has an important role in the development of the field of powder metallurgy in my country. The author will do a comprehensive research and analysis of powder injection molding technology, and conduct related research on its application in metallurgical fields such as insoluble tungsten alloys.

Application of tungsten alloy in the field of metal injection molding(图1)

At present, people are paying great attention to the development of cutting tools and small cemented carbide tools for difficult-to-process materials and wood processing (printed circuit board drilling and welding micro-drills and teaching electrodes). In order to produce the above products, they are usually used In terms of performance, it is significantly better than standard alloy fine-grained cemented carbide. The tungsten-based fine-grained and ultra-fine-grained cemented carbide used in my country's industry is characterized by the use of relatively coarse tungsten powder and an average particle size of 4-9μm Tungsten carbide powder.


Refractory tungsten alloys and cemented carbides are widely used in industry. This article mainly introduces the new developments in ultra-fine/nano tungsten alloys and cemented carbide powders and alloy preparation technologies in recent years, focusing on injection molding, spray conversion , Sol-spray drying-thermal reduction and alloy grain control technology, and pointed out the future research and development direction of tungsten alloy and cemented carbide.


Qinhuang Daolong Co., Ltd. was established in July 2007. It produces powder metallurgy and metal injection molding MIM technology, and produces a variety of mixed hardware and mechanical parts.


Powder micro injection molding technology (μPIM) is a new type of technology that uses traditional powder injection molding methods to prepare products with an overall size of millimeters, a particle structure of micrometers, and micrometers of fineness. It is extremely bright because The characteristics of titanium alloy processing can be realized by using micro-alloy parts made of μPIM, mass production, currently in use, high-end preparation and synthesis fields have been ordered for tungsten alloys prepared by μPIM technology.




Tungsten alloy has low density, high specific strength, good biological properties and oxidation resistance, aerospace resistance and other characteristics, and it has application prospects in aerospace, automotive, defense, medical, chemical and other fields. Injection molding technology (PIM) realizes the manufacture of small and medium-sized composite titanium and titanium products, which is of great significance for the production development and application of titanium alloy products. Can briefly introduce the characteristics and advantages of plastic molding titanium alloy, develop the research progress of titanium alloy foam molding technology from the aspects of powder preparation, catalyst application technology, powder foam molding technology, material properties, etc., and aim at the current existing problems, Formed the research direction and development direction of the main molding materials of foam molding.
