• Other Auto Parts

Our company has three factories located in Hiroshima Prefecture and delivers our products worldwide through our customers. We have established our position as a parts processing manufacturer primarily focused on automotive and agricultural machinery. We have a production system that can consistently handle everything from prototyping to production preparation and mass production, focusing on pipe processing, press processing, welding, and assembly, as well as painting, plating, heat treatment, surface treatment, and functional testing. 【Processing Example】 ◆Product: Automotive shaft parts ◆Size: Small to medium ◆Material: Steel (SPHC) ◆Processing Method: Press, machining-free ◆Traditionally, we used press processing followed by internal diameter machining, but by innovating the press processing method, we have achieved completion of the process solely through the press processing stage using a standard press machine. (Ensuring all shear surfaces for the internal diameter) *For more details on processing examples, please refer to the catalog available for download below "PDF Download."

To connect Φ8.0 pipes in a T-shape, we drilled holes and split the pipes near the T to remove the drilling debris. After removing the debris, we welded them together in an I-shape. By developing a new drilling method that discharges the debris outward, we achieved cost reduction through a decrease in the number of pipe components and welding points, improved quality by reducing foreign matter inside the pipes, and increased productivity by reducing the work processes. 【Case Summary】 ■ Cost Reduction - Number of pipe components: 3 → 2 - Number of welding points: 4 → 3 - Price: Processing cost down by 22% ■ Quality Improvement - Rate of foreign matter inside pipes: 20% → 0% *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where the stopper component of the propeller shaft (powertrain part) was processed without a machining process. To achieve press-fit joining to the shaft, the inner diameter tolerance is ±0.025. Traditionally, this involved pressing followed by inner diameter machining. By innovating the pressing method, we successfully ensured a quality with an inner diameter tolerance of ±0.025 and a surface roughness of Ra3.2 or less, using only the pressing process on a standard press machine. [Case Study] <Pressing + Machining ⇒ Pressing only> ■ Cost Reduction ・Reduction of machining processes ・Price: Processing cost down by 33% ■ Improvement in Production (Work) Efficiency ・Increased productivity by reducing logistics losses of work-in-progress *For more details, please refer to the PDF document or feel free to contact us.
