Heat Treatment
The heat treatment business is a field that must be performed to improve the mechanical and chemical properties of all metals such as iron and non-ferrous metals.
It is applied to parts and mold materials of most machines, semiconductors, automobiles and aircrafts.
Therefore, it is a business that has been applied to industry in general in terms of its application and utilization.
Since 1995, we have been operating the first company-affiliated research institute in Korea with the goal of establishing industrial-based technology. We are applying environmentally friendly, technology-intensive, and economic excellence as an integral part of our development process.
Therefore, we are steadily conducting R & D in the areas of environmentally friendly, highly efficient industries such as Plasma, Vapor Deposition and Vacuum Technology.
We have been awarded as a venture company, heat treatment contest, technology competitiveness company, SQ certification, IATF 16949, ISO9001 certification and 13 patents.
With the recent global interest in environmental issues, a bill to regulate the use of pollutants, including destruction of the ozone layer and induction of cancer, was established on July 1, 2003.
As a result, the commercialization of eco-friendly and economical process technology developed by our company has been attracting much attention.
OXY Nitriding Surface Treatment
The oxynitriding process has the advantages of an environmentally friendly process that does not emit harmful substances compared to electrochemical plating (nickel / chrome) and salt bathing process for strengthening existing corrosion resistance. Because of this characteristic, Is recognized as a process that can cope with global environmental regulations on harmful substances in the environment.
Plasma Nitriding
Environment-friendly No pollution-free and energy-saving plasma is used to perform metal surface treatment Reaction temperature is lower than conventional gas or bath method to prevent deformation of product before and after treatment. This is a process that improves the characteristics.
Gas Nitriding
Unlike carburizing and high-frequency heating, N is infiltrated into the surface of a steel by heating at about 500 ° C in an NH3 stream to produce a cured layer of iron nitride, and thereafter the 'need for pneumatic operation', 'wear resistance of parts' Is a process that improves 'properties'.
Vacuum Carburizing Surface Treatment
It is a technology that penetrates CARBON in vacuum. It is a state-of-the-art heat treatment method that can design process conditions using simulation program according to materials and requirements, carburization speed is over 50% faster, and there is no grain boundary oxide layer on the surface.
Vacuum Heat Treatment
It is a process that improves the toughness, strength, hardness and other characteristics of parts without deformation during processing by changing the metal structure in a vacuum state using a vacuum device.

OXY Nitriding Surface Treatment
Oxy Nitriding SurfaceTreatment
The development of the oxynitriding process has led to the worldwide use of plasma nitriding technology to improve the corrosion resistance of parts.
In particular, the Ionitox process has made it possible for the first time to perform both conventional commercial nitridation processes and plasma nitridation processes such as gas nitridation and gas softening.
Although its origin is short, it is widely used in the heavy industry such as machine and automobile industries and various industrial plants for excellent corrosion resistance of parts, excellent wear resistance, increase of surface hardness and enhancement of abrasion resistance.
The oxynitriding process has the advantage of an environmentally friendly process that does not emit harmful substances compared to electrochemical plating (nickel / chrome) and salt bathing processes to enhance existing corrosion resistance.
