Extra-Drawn Products

Many metal materials are shaped by methods such as casting, joining, cutting, and plastic processing, but the processing method is decided after a comprehensive consideration of factors such as shape, material quality, dimensions, quantity, and processing costs.

Among these, plastic processing is notable for its lower processing costs compared to other processing methods, and is used for many products.

Plastic processing methods include rolling, extrusion, drawing, forging, rolling, and sheet metal pressing, but SILD's special-shaped drawn products are manufactured using a combination of hot rolling and cold drawing to meet customer product specifications, such as dimensional accuracy, length, bending, mechanical properties, and decarburization.

Features of Cold Drawing

Benefits of SILD

We can meet your needs by combining hot (cold) rolling and cold drawing.

We can complete all processes in-house, including material selection, hot (cold) rolling, heat treatment, die manufacturing, cold drawing, straightening, cutting, testing, and inspection.
