Our MIM process support below design princinple. We also have professional engineers to design the drawings as customer required.

Recently, mechanical watch or stem-winder, i-watch and electronic watch grwoing very quickly. Then our Shandong No2 Machinery Company developed many steel parts like watch shell, union joint and watch chain.

Recently, many new moulds have to make a modification again because of design defect. Some of them also the responsibility of us, we donnot make them correctly as tolerance.

We quote them if they are in one mould based on the similar structure, geometry, weight to analize the part line, sliders and pattern of moulds. Some complex and different structures could not be combined.

Catamold method is a one-step degreasing method developed by Bloemacher of BSAF Company in Germany in the early 1990s. It is a catalytic degreasing method.

In terms of technology, the company has a professional MIM R&D team. After years of efforts, it has solved the technical problems in mass production, ensured the accuracy and quality of products, and won unanimous praise from customers.

Today, we finished the samples-wrench or MIM spanner to a customer near our factory. This is a new sample, having irregularly outshape.

In terms of production equipment, the company invested in the introduction of Shimadzu vacuum degreasing sintering furnace from Japan, using the German BASF catalytic degreasing production technology, equipped with CNC machine tools, heat treatment furnace, magnetic grinding machine, carbon and sulfur analyzer, flaw detector, density analyzer and other professional production and testing equipment, to ensure the product performance.

In terms of software and hardware, the company has independent intellectual property rights of feeding, professional design and manufacturing of molds.

n recent years, with its good reputation and excellent product quality, our Shandong No2 company has begun to emerge in the MIM industry, and is well known and accepted by more and more customers, especially in the field of military MIM parts manufacturing, we are in the leading position in the powder metallurgy industry.

Metal Injection Molding (MIM) is a high and new technology, which is the conbination of a traditional Powder metallurgy technology and plastic Injection Molding technology.

We had been working from 5.1 labor holiday. Everything looks smooth. These days there are some new MIM samples to produce and test, so the quality Dep. and Production line will always mount the mould into machine, try again and again.

Shandong No2 Machinery Company is one of the leading MIM suppliers in China, we have been specializing in the field of auto accessories, gun parts, lock spare parts for over 15 years.

We are Shandong NO.2 Machinery MIM Factory in China. Our MIM technology reach the top point in China. We now have our own material lab and researchers.

n China MIM materials, 85% of them are stainless steel and low alloy steel, 10% is tungsten, 5% are others. In stainless steel, main material are 316L and 17-4PH. Report forecasts that in short future, MIM materials will be diversified, including nickelless stainless steel, nonmagnetic alloy, aluminum alloy and high thermal conductivity alloy etc..

Until now, we had developped 3 MIM items for them, about worthing US Dollars 1 million.

Shandong No2 Machinery Company is one of leading manufacturer in China. We have aboundent experiences on MIM process for more than 14 years.

In order to prevent oxidation and reduce decarbonization, methods are as follows: parts surface coating; sealed heating with stainless steel foil; heating with salt bath furnace; heating with protective atmosphere (such as purified inert gas), flame combustion furnace (making furnace gas reductive).

The design of MIM mold structure plays an important role in injection molding parts. High quality molds can improve the forming quality and comprehensive performance of parts.

Excessive heating temperature not only causes austenite grains coarse, but also causes local oxidation or melting on grain boundaries, leading to grain boundary weakening, which is called overburning.
