Business Areas

• Precision Heat Treatment Processing for Automotive Powertrain Parts: We provide advanced heat treatment services such as quenching, tempering, and normalizing for transmission and gear parts that determine the power transmission efficiency of automobiles. By relieving internal stress and homogenizing the microstructure to achieve optimal mechanical properties, we create core manufacturing value that ensures parts do not fail even in high-speed rotation and high-load environments, maintaining long-term durability.
• Heat Treatment for Wind Power Generation Parts: We provide heat treatment services for metal parts required in the wind power generation industry, contributing to the improvement of part durability and performance.
• Heat Treatment for Heavy Equipment Parts: We perform heat treatment processing for metal parts used in various heavy equipment, ensuring strength and lifespan that can withstand extreme environments.

Products

• Quenching & Tempering (Q&T) Service: This is a heat treatment process that increases hardness by heating metal materials to a high temperature and then rapidly cooling them, followed by reheating to an appropriate temperature to impart toughness. This maximizes the strength and hardness of the metal, thereby improving product durability.
• Normalizing: This is a heat treatment process where metal materials are heated to a high temperature and then naturally cooled in the air. It aims to form a uniform microstructure, increase impact resistance and ductility, improve machinability, and relieve residual stress.
• Annealing & Spheroidizing: This is a heat treatment service that improves workability by increasing the ductility of metal and relieving internal stress. Spheroidizing, in particular, focuses on improving the workability and toughness of the metal by forming carbides into spherical shapes.

Special Notes

• Technology-Intensive Strong Small Company: Since its establishment in 2000, the company has accumulated expertise in precision heat treatment for approximately 25 years, focusing on maximizing the hardness and durability of metal parts such as automotive transmissions and gears.
• Global Level Quality Competitiveness: Registered as a partner company of ZF, the world's largest transmission manufacturer in Germany, and having obtained the SQ certification from Hyundai and Kia Motors and the IATF 16949 international quality standard, the company has clearly demonstrated its global-level technological competitiveness.
• State-of-the-Art Facilities and Strict Quality Control: The headquarters, located in the Dasan Industrial Complex in Goryeong-gun, Gyeongsangbuk-do, serves as a key supplier to the domestic and international automotive industries, based on its state-of-the-art heat treatment facilities and strict quality management system.

Recruitment Information

• Main Hiring Positions: We are primarily recruiting for heat treatment operators (experienced personnel for Q.T/N.R foreman level) and prefer candidates with metal-related certifications (e.g., Industrial Engineer Metal Materials Testing).
• Benefits: Welfare benefits include an in-house cafeteria and meal support, and birthday celebrations with cake delivery and congratulatory messages.
