Input Raw materials produced by major domestic and overseas steelmakers are gathered according to customer needs.
Heating The heating process takes place in a furnace equipped with an automatic temperature control system, specified to the characteristics of each product.
Forging The forging process uses a PRESS between 2,500~6,500 tons, depending upon the size of the mold.
Cutting The cutting process is intended to produce a suitable form according to a product's shape.
Treatment The heat treatment is intended to homogenize the product and remove residual stress.
Processing The processing process in intended to match product shape and dimensions according to customer needs.
Shrink Fitting A special process which heats and assembles parts for 2ST crankshaft production.
Special Heat Treatment A process for manufacturing products requiring special heat treatment, such as nuclear/thermal power generation and defense parts.
Final Processing Final processing of the 2ST crankshaft using specialized equipment.
Inspection A final inspection is performed using each type of testing equipment to select only the best quality products.
Packaging Products are delivered after packaging in order to maintain the highest quality for customers.
Forgingrefers to the process of applying a compressive load to a particular material with the use of various molds and tools in order to produce a desired shape.
