Business Areas

• Casting Division: We manufacture cast components compliant with international standards for various materials, including spheroidal graphite cast iron (FCD) and compacted graphite iron (CGI). We produce parts requiring complex shapes and high-precision machining with our unique technology, supplying core components for various construction equipment and railway parts.
• Production and Supply of High-Precision Hydraulic Component Casting Materials: We produce core casting materials such as Main Control Valves (MCV) and hydraulic valves used in construction and industrial machinery like excavators, forklifts, and loaders, supplying them to domestic and international construction machinery and heavy equipment manufacturers. We operate a B2B business model that provides optimal alloy design and casting solutions tailored to our customers' design specifications.
• Engineering Business Division: We are focused on developing and commercializing high-value-added casting new technologies and new materials. Through this, we are continuously challenging ourselves in technological development with the goal of becoming a world-leading specialized company in the field of hydraulic equipment materials.

Products

• Main Control Valve (MCV) for Excavators: It is a core component that controls the flow and pressure in an excavator's hydraulic system to regulate the machine's operation. We produce various models such as CGI 350, CGI 420, CGI 450, and FCD 500.
• Control Valve for Forklifts and Valve Body for Loaders: We manufacture control valves (CV material) that play an important role in forklift hydraulic systems and valve bodies (FCD material) that control loader hydraulic systems. In particular, we successfully developed and mass-produced the localized Parker loader valve (M402LS).
• Brake Discs for Railway Vehicles: We produce brake discs, which are core braking components for the safe operation of railway vehicles, and supply them to Korail and other clients. We have been recognized for our high technological capabilities, including being the first in Korea to export products to the Chinese railway market.

Special Notes

• Unique Technology and Development Capabilities: We produce high-quality cast products based on casting technology compliant with international standards such as KS, JIS, and ASTM. We possess unique technological capabilities for various materials, including spheroidal graphite cast iron (FCD) and compacted graphite iron (CGI).
• Strict Quality Control and High Reliability: We provide reliable quality to customers by establishing precise production technology and a strict quality control system. Our quality management capabilities have been externally recognized through our selection as an excellent partner by Hyundai Heavy Industries in 2008 and receiving the Presidential Commendation for Exemplary Small and Medium-sized Enterprises in 2020.
• Leading Localization of Core Materials: We are leading the localization of core component materials for construction machinery, which were previously reliant on imports, thereby contributing to strengthening the competitiveness of the domestic construction machinery industry. Through this, we supply products to leading domestic companies such as Hyundai Heavy Industries and Doosan.

Recruitment Information

• Main Hiring Positions: There may be casting manufacturing-related positions such as casting production, casting technology, quality control, and production management, but specific information on currently open job postings or frequently hired positions is not available.
• Benefits: We provide the four major insurances: National Pension, Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance.
