Both powder metallurgy technology and injection molding technology belong to special processes, precision manufacturing, and have good material saving processing characteristics. In some fields, powder metallurgy technology may be more suitable for powder metallurgy technology, and some precision parts will choose injection molding technology, depending on the customer Minxin Powder will give you an in-depth explanation of the difference between these two technologies, so that everyone is no longer unfamiliar with powder metallurgy.
One: What is powder metallurgy technology?
1: Powder metallurgy technology was first used in the United States in 1870. It used a metal powder as a raw material, and then pressed copper-lead alloy bearings to realize the self-lubricating technology of the bearing, and produced various parts and components through pressing and sintering.
2: The powder metallurgy technology process sounds unfamiliar to everyone, but if I speak a little bit more popularly, it will be easy for everyone to understand. The general procedure is to first decompose the main material into fine powder, then add the powder to the required mold, then form the model by pressure, and finally perform sintering to complete all the steps.
Two: What is injection molding technology
1: Injection molding technology was born in California in 1973, referred to as MIM, which is a new type of powder metallurgy molding technology invented by combining plastic injection molding technology with the field of powder metallurgy.
2: The injection molding technology process is relatively close to the powder metallurgy technology. First, the solid powder and the organic binder are uniformly mixed, then heated and plasticized at a high temperature of 150 degrees, injected into the mold cavity with injection molding equipment, and then solidified and molded, and then used The thermal decomposition method removes the binder in the formed blank, and finally, like powder metallurgy, precision parts are produced through sintering.
3: What is the difference between powder metallurgy and injection molding technology?
For laymen, powder metallurgy and injection molding are relatively unfamiliar. It is considered to be two completely different production and processing technologies. In fact, powder metallurgy technology includes injection molding technology, because injection molding technology is one of the parts molding technologies in powder metallurgy technology, and the other is press molding.
Through the above in-depth explanation, I believe that everyone has a deep understanding of powder metallurgy technology and injection molding technology and the difference between them. Powder metallurgy injection molding will be used in automotive, electronics, hardware, medical equipment, communications and other fields. Compared with traditional technology, the technology has higher precision and lower production cost, so it is also the mainstream technology of various parts processing and production.
