Low-temperature grinding (I.M MATERIAL)

Low-temperature grinding using the cold heat of liquid nitrogen

I.M. Material Co., Ltd.

At I.M. Material (Moriroku Group company), we use strict quality control measures to crush materials that are sensitive to heat and cannot be ground at room temperature, such as elastomers and low-melting-point resins, by employing liquid nitrogen (-196℃) for cryogenic grinding.

We cater to our customers' needs, from small sample tests to large-scale production. (Contract Grinding Service)

I.M. Material's low-temperature grinding technology

What is low-temperature (cryogenic) grinding?

grinding involves pulverizing materials that have low melting points, such as elastic rubber or resins, which are difficult to grind at room temperature. This process uses liquid nitrogen (at -196°C) to make these materials brittle before grinding.
What are the features of low-temperature (frozen) pulverization?

What are the characteristics of low-temperature (cryogenic) grinding?

There is minimal heat generation during grinding. This method prevents the deterioration and degradation of the ground products' quality, and the grinding is performed in a nitrogen atmosphere to suppress oxidation.

What is the outcome of products after low-temperature (cryogenic) grinding?

The surface of the particles is smoothly finished after grinding. At room temperature, grinding results in ductile fractures with whisker-like structures. However, low-temperature (cryogenic) grinding leads to brittle fractures, similar to breaking rocks.
