We would like to introduce the manufacturing process of forged products at Edogawa Kanko Co., Ltd. First, materials are received, followed by cutting and heating processes, and then we proceed to the forging process, using forging presses, hammers, and friction presses for the work. After trimming, heat treatment, and shot blasting, the products undergo magnetic particle inspection before shipping. 【Process Steps】 ■ Material Receipt ■ Cutting ■ Heating ■ Forging: Forging Press, Hammer, Friction Press ■ Trimming ■ Heat Treatment ■ Shot Blasting ■ Inspection: Magnetic Particle Inspection ■ Shipping

Forging is a technique that involves applying force to metal to change its shape (forming) while also strengthening the metal structure. In simple terms, it means striking (hammering) iron to shape it while making it stronger, where the "tan" in "tanzou" refers to the "tan" in "training," meaning to forge. By striking, the gaps in the solid are eliminated, creating one strong solid, and when hot, it can easily be transformed into various shapes. 【Lineup (partial)】 ■ Gears 0.7–5.7kg ■ Flanges 1.3–5.2kg ■ Lift Cranks 1.6–5.2kg ■ Rods 0.07kg ■ Crankshafts 0.8–10.9kg *For more details, please refer to the related links or feel free to contact us.
