飯塚製作所 Product Lineup

We are stably mass-producing high-precision, complex-shaped parts, with approximately 40 million seatbelt components produced annually. - Mass production of complex-shaped parts using only cold forging (without cutting). - Transitioning from die casting to cold forging has contributed to cutting-free production, high strength, and reductions in weight and cost. - Transitioning from welding to metal riveting has increased strength and enabled automation for mass production. - Cold forging of aluminum.

Airbag components are referred to as important safety components. They are used in systems that play a significant role in protecting human life and ensuring the safety of the vehicle in the event of an accident. They play a very important role among automotive parts.

• Other Auto Parts

【Development Case 1】 We have successfully manufactured hollow components for automotive engines made of Inconel, which has superalloy properties, high hardness, heat resistance, and corrosion resistance, through cold forging for the first time in the world. This has helped our customers reduce costs. 【Development Case 2】 We challenged ourselves with cold forging of stainless steel. Although we struggled to meet the required levels of material hardness and dimensional accuracy of the parts, we succeeded in miniaturization and weight reduction by eliminating the chuck portion that could not be removed through machining.

• Engine parts

As a cold forging company, we possess a wealth of know-how by conducting prototypes and trials in-house. We handle film types that have been tested and proven through our in-house prototypes and trials, and thanks to our established processes, we excel in film adhesion, resulting in improved lifespan and quality, with numerous achievements in-house.
