Introduction to AIM process and development status of AIM production equipment

MIM and CIM are two branches of powder injection molding technology. Among them, MIM is the earliest and most mature branch, known as the most popular part forming technology in the 21st century, and it has not failed to live up to such an honor. Its industry continues to develop and grow, and it has special metal injection molding production equipment. Now the metal powder injection molding process has a third branch: AIM, namely aluminum alloy injection molding.

In recent years, with the continuous maturity and popularity of metal injection molding technology, people have also paid more and more attention to aluminum alloy, a special composite metal with excellent functions. Because of the characteristics of aluminum alloy, which has a wide variety of properties, and its surface is very easy to be oxidized, its requirements for injection molding are different from those of ordinary metals or alloys, so special AIM&mdash& mdash; Aluminum alloy injection molding.

If any process wants to develop in an all-round way and form an industry, it must improve the production efficiency of the enterprise through the improvement and upgrading of production equipment. AIM is no exception. At first, it did not have special equipment. The traditional general production equipment for powder metallurgy and injection molding industry and the special equipment for metal injection molding have been used in this process. However, it has its unique raw material characteristics, and those non-specialized production equipment can not meet its normal production needs well, even if it can barely use the quality of the product is also greatly discounted.

The research on AIM production equipment (mainly mixing and granulating equipment and injection equipment) has only begun in recent years, because the aluminum alloy injection molding technology is a very advanced technology, and the domestic research on it has just begun. At present, Nanjing University of Science and Technology has done more research in this field earlier and has achieved certain research results, and its level in this field can reach the top three in the world. Because the friction coefficient of aluminum alloy powder is smaller than that of common metal powder and ceramic powder, the mixing equipment and injection equipment can be shared in principle.

With the improvement of production efficiency, equipment automation, processing continuity and equipment performance of AIM enterprises, the research of professional aluminum alloy injection molding mixer, granulator and injection molding machine has been put on the agenda of many mechanical equipment manufacturers.

At present, a few domestic mechanical equipment manufacturers have achieved preliminary results in the research, development and production of AIM special production equipment through cooperation with colleges and universities, and have begun to use it in some enterprises. Its functions and characteristics still need to be explored and improved in future production practice. I believe that with the continuous progress of science and technology, these production equipment will also develop towards intelligence, environmental protection and automation
