Hita Factory

Features of the Factory

Custom-made production of various springs with our unique technology

The Hita Factory manufactures various springs such as push springs, pull springs, twist springs, and plate springs made to order using our unique technology. We can handle wire diameters from φ0.5 to φ12, and carefully manufacture them by making full use of our wisdom and technology in each and every processing step. We can flexibly respond to prototyping and prototype changes.
In 2024, we introduced the MX-40B forming machine (Itaya Manufacturing Co., Ltd.), which enables us to manufacture large-lot production and complex torsion springs. We also accept small-lot and multi-variety thin sheet spring production by laser processing. Laser processing machines are capable of processing plate thicknesses from 0.05 to 6.0.

Improving individual skills and passing on craftsmanship

We are working on “improving individual skills” and “passing on craftsmanship” in order to meet customer deadlines and quality. We are constantly striving to improve productivity and speed up the work process by leveling the workload and building a system that allows employees to handle various tasks.
We also strive for quality assurance through thorough process inspections (front-end process, own process) in each processing process.

Know-how and high technology accumulated over many years

The predecessor company of our factory was established in 1963, and has been doing business with customers throughout Kyushu for many years. Since its establishment, the company has been dealing with small-lot production of a wide variety of products, and the accumulated know-how and high level of technology have been passed down to the present day.
Springs are used in a wide variety of products, and our customers have a wide range of requests, but we place emphasis on “customer satisfaction” and strive for speedy response and quality improvement. We also manufacture the necessary processing jigs and dies in-house to reduce die costs.
