"Plastic processing" refers to the method of shaping materials into desired forms and dimensions by utilizing the property of plasticity. Plasticity includes ductility and malleability; ductility is the property that allows a material to stretch when pulled, while malleability is the property that allows a material to expand when force is applied. "Forging" is a processing method that shapes metal by hammering, while "extrusion" is a processing method that shapes material by pressing it against a mold with a hole to achieve the desired shape. [Types of Plastic Processing] ■ Forging ■ Extrusion ■ Pressing *For more details, please refer to the PDF document or feel free to contact us.

"Drawing processing" is a method of processing where material is passed through a mold (die) that has been drilled to the desired shape, and is then drawn to transform it into the intended shape and dimensions. Since this is done at room temperature and gradually approaches the desired shape, it achieves high dimensional accuracy, and due to work hardening, improvements in mechanical properties such as wear resistance can be expected. Additionally, because it is not a subtractive process, the yield is higher. Our company performs rolling processing for rough shaping and drawing processing for precision shaping, and we manufacture custom products tailored to customer requests using this combination.

"Rolling processing" is a method of shaping materials by passing them between a pair or two pairs of rollers, and it may be easier to understand if you imagine a noodle-making machine. There are two types of rolling processing: "hot rolling" and "cold rolling." Hot rolling is performed by heating the material to make it easier to deform, while cold rolling is done at room temperature. Our company conducts flat rolling, which shapes cylindrical round bars into flat rectangular shapes, and shape rolling, which shapes materials into various forms.

Metals possess both plasticity and elasticity. Elasticity is the property that allows a material to return to its original shape after being deformed by an applied force. For a familiar example, think of a rubber band. When you gently stretch a rubber band and then release it, it returns to its original shape. This ability to return is called "elasticity." However, if a certain amount of force is applied, once that force is removed, the material may not return to its original shape. This limit of returning is referred to as the "elastic limit." The property where deformation remains even after the force is removed is called "plasticity." We provide a detailed explanation using illustrations and diagrams, so please take a look at the PDF download. *For more details, please refer to the PDF materials or feel free to contact us.*

Our products are manufactured using rolling and drawing processes. Both rolling and drawing are methods of "plastic processing." However, it may be difficult to imagine what plastic processing entails. In this document, we will briefly introduce topics such as "What is plasticity?", "What types are there?", and "What are rolling and drawing processes?" to help clarify these questions. Please take a moment to read through it.
