The instability of metallic materials and non-metals (tissue metamorphism and processing produces internal stress) causes instability in production, and over-reliance on workers has been plaguing the industry. The company spirit of "first-class technology, first-class efficiency, first-class service", to ensure that the effect of material deformation, to ensure processing dimensional accuracy, increase wear resistance, increase elasticity, eliminate stress, make the organization fine, and thus improve quality, cut costs.

Ultra-cold technology is the only process that can be used in the processing of tools, tools, and parts after heat treatment. It can stabilize the precise dimensions of materials, improve the wear resistance of materials, and restore the mechanical properties of materials.

The treatment of materials by ultra-cold technology is not limited to the surface treatment of materials, but also penetrates into the internal structure of the material, which reflects the overall effect, especially the re-grinding of cutting tools, does not affect the structure of the structure, can be used repeatedly, and its reusability Significantly superior to coating technology. The ultra-cold treatment technology can effectively reduce the quenching stress and enhance the dimensional stability of the workpiece.

In the face of the transformation and upgrading of the industrial structure, the competitiveness of traditional industries must make correct changes. The guarantee of product quality will change from competitive conditions to living conditions. The improvement of the efficiency of industrial products is a problem faced by industrial people. However, the basic engineering of metal materials is more important. The basic work of heat treatment makes the quality of industrial products not perfect. Although heat treatment gives life to metal materials, it does not give life and efficiency. In addition to the previous heat treatment, the complete basic engineering also includes the subsequent metal ultra-cold treatment, which is the basic work to ensure product quality. DeepCryogenicTreatment will be the only choice for the quality of metal products.

The ultra-cold application industry includes: precision stamping dies, nano materials, precision plastic molds, cutting tools, hobbing cutters, aluminum alloy materials, carbide cutting tools/clamps, powder metallurgy molds, etc.

Ultra-cold treatment for high speed steel

During the ultra-cold treatment, a large amount of retained austenite in the metal is transformed into martensite, the supersaturated metastable martensite is reduced in its saturation, the microscopic stress is reduced, the dispersion is precipitated, and the dispersed ultrafine carbide is precipitated. The plastic deformation of the material effectively hinders the dislocation movement, thereby effectively strengthening the matrix structure. Since the ultrafine carbide particles are uniformly distributed on the martensite, the grain boundary is effectively strengthened, thereby improving the performance of the high speed steel and greatly improving the impact toughness, the red hardness and the wear resistance.
