Cutting processing has a high degree of freedom in shape and is a processing method that can easily accommodate complex shapes. On the other hand, it requires the removal of a large amount of material as chips to achieve the final shape, resulting in material loss. As the complexity of the shape increases, the amount of material removed also increases, leading to a significant impact on product costs due to reduced yield. This is particularly significant for expensive materials such as stainless steel and special steel, where the material costs lost as chips cannot be ignored. Additionally, cutting processing of long materials tends to have longer processing times, necessitating consideration of deformation and bending due to processing heat and stress.

Our company shapes irregular cross-sections tailored to customer specifications by combining rolling and drawing processes. Since the drawing process forms the material into the desired shape through plastic deformation, it does not generate a large amount of cutting chips like machining does, resulting in minimal material loss except for the ends of the products. Therefore, cost reduction through improved material yield can be expected. Additionally, even for long products, we can consistently shape the cross-sectional profile and surface condition, contributing to quality uniformity and reduced burden on secondary processing. Irregular drawing processing is a method that generates benefits in both cost and quality.

Compared to machining irregular cross-sections from round bars, irregular extrusion processing can significantly improve material yield. Depending on the product shape, it is possible to achieve over a 50% improvement in yield based on cross-section. Furthermore, irregular extruded materials are produced in long lengths, allowing them to be cut to the desired length for various applications. In mass-produced products, the effects of reducing material waste and improving efficiency in subsequent processes accumulate, leading to significant cost reductions. *The green part in the left diagram represents the material removed during machining (cutting loss).
