Polishing Technology of MIM Metal Injection Molding Precision Parts

Polishing Technology of MIM Metal Injection Molding Precision Parts

The polishing technology of MIM metal injection molding precision parts is the content to be shared today, so what MIM materials need polishing? Let's follow zhongwei to have a look.

1： What MIM material needs polishing?

The parts materials commonly used in MIM metal injection molding are: copper base, iron base, stainless steel, alloy, etc. The materials to be polished are: stainless steel and iron base, especially stainless steel, which has a wide range of applications. The precision parts made of MIM stainless steel also have excellent performance, corrosion resistance and wear resistance.

1: Magnetic abrasive polishing technology

Magnetic abrasive polishing is to use magnetic abrasive to form abrasive brush under the action of magnetic field to grind precision parts. The magnetic abrasive polishing technology has high efficiency, good quality and easy operation. It is a widely used polishing technology for precision parts.

2: Mechanical polishing technology

After mechanical polishing, the precision parts have good levelness and gloss. However, the pollution to the environment and products is relatively large, and the gloss maintenance time is not long, which is easy to cause problems such as stuffiness and rust, so some simple and cheap parts will be operated by mechanical polishing technology.

3: Chemical polishing technology

Chemical polishing technology can be used to polish even large and complicated precision parts, and it has fast processing speed, high efficiency and good corrosion resistance. However, there is a peculiar smell in the processing process and the glossiness is not very good, so some precision parts that do not require high glossiness will use chemical polishing technology.

To sum up, it is the sharing of polishing technology of MIM metal injection molding parts. I hope this article will help you. If you need to know more, please pay attention to the official website of zhongwei Precision.
