Look below for detailed descriptions of each process.
1

Raw Material
Input
Raw materials produced by major domestic and overseas steelmakers are gathered according to customer needs.

2

Heating The heating process takes place in a furnace equipped with an automatic temperature control system, specified to the characteristics of each product.

3

Forging The forging process uses a PRESS between 2,500~6,500 tons, depending upon the size of the mold.

4

Cutting The cutting process is intended to produce a suitable form according to a product's shape.

5

Heat
Treatment
The heat treatment is intended to homogenize the product and remove residual stress.

6

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.

7

Inspection A final inspection is performed using each type of testing equipment to select only the best quality products.

8

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.
