Technical Data - Processing Technology (Forging)

Processed products have refined structures and improved wear resistance.

Forging is the process of compressively forming metallic materials (carbon steel, stainless steel, alloy steel, non-ferrous metals) using molds, applying external forces that exceed the elastic limit to create permanent deformation and achieve the desired shape and dimensions. The processed products have a refined microstructure, resulting in improved wear resistance. The advantages include the continuity of metal fibers (fiber flow) and the increase in strength due to work hardening, which can enhance machinability in the case of soft materials, potentially allowing for the use of less expensive materials and the omission of heat treatment. The notable aspect of this processing method is its high efficiency, capable of producing several to hundreds of pieces per minute, allowing for the material to be shaped into its final form or a state close to it. Additionally, it offers high forming precision, reducing the need for further processing in subsequent steps. Forging can be broadly categorized by temperature into three types: "hot forging," "cold forging," and "warm forging." Forging encompasses various deformation styles, including end-face correction, forward extrusion, backward extrusion, upset forging, hole punching (piercing), and blanking (trimming), among others. *For more details, please download the PDF or contact us.*

Miyamoto Industrial Co., Ltd. Business Introduction

Leave it to us for mold design and manufacturing, as well as cold and hot forging products.

Miyamoto Industrial Co., Ltd. has been supplying products that benefit our customers as a "technology-oriented" development company since its founding in 1918 (Taisho 7). Since pioneering the mass production of shock-extruded tubes in Japan, we have produced and sold a wide range of forged products including camera parts, VTR parts, industrial equipment, low-voltage components, computer-related parts, automotive and motorcycle-related parts, stationery, tools, and leisure goods. We have been crafting the molds essential to forging in-house since our establishment, honing our proprietary techniques. In this era of global competition, we aim to return to our roots and position ourselves as a proposal-oriented company focused on technology and development, continuing our efforts day and night as we strive towards our 100th anniversary. We appreciate your continued support for our "beautiful forged products." [Business Activities] - Cold and hot forged products - (Cold) impact molded products - Simulation analysis using CAE - Design and manufacturing of forging molds - Design and manufacturing of various production automation equipment - Production and sales of mechanical devices (such as shear machines) For more details, please contact us or download our catalog.

Shortening of Joining Processes: Types and Applications of Forging

By crushing, it can be processed into various shapes! A technique that induces work hardening in metal materials to increase strength.

Forging is a type of metal processing that involves shaping metal materials by hammering or pressing them into various forms. It is classified into three types based on the temperature during the forming process: cold (room temperature), warm (600–900°C), and hot (900–1250°C). Our company employs "cold forging" using a press machine. By using cold forging technology to create "integral shapes" from parts that have been joined through welding, crimping, or fitting, we can enhance the strength and reliability of the components. 【Types of Forging (Partial)】 ■ Cold Forging - Processing temperature is at room temperature (20–30°C) - Capable of forming with higher precision in dimensions and surface accuracy than warm or hot forging - Reduces the need for cutting processes - Aims for cost reduction of products *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Near-net shape cold forging of hot forged material!

Further shaping hot forged materials through cold forging! Achieving near-net shape products with irregular shapes.

By using hot forged materials, we have made it possible to shape irregular forms, which is a weak point of cold forging. There is no need for a draft taper like in hot forging. This is a forging method that combines the high precision of cold forging with the irregular shapes of hot forging. 【Features】 ■ Since a cold forging process is involved, there is no need for a draft taper like in hot forging. *For more details, please refer to the PDF document or feel free to contact us.
