[Proposal Example] Cold Forged Pin for Reclining Seats

[Proposal Example] Cold Forged Pin for Reclining Seats

Reduced unit cost of parts by approximately 70%, shortened processing lead time from 20 days to 3 days! Introducing a case of cost reduction through cutting-less methods.

We would like to introduce a case where we proposed "cold-formed pins for reclining seats" for automobiles. In this case, the challenge was that costs were high due to cutting and deburring processes. Therefore, by cold-forming the slit (slitting) section, we were able to reduce cutting and deburring costs, achieving shorter processing lead times and stable quality. [Case Overview (Partial)] ■Challenge - High costs due to cutting and deburring processes ■Results - Formed solely through cold forging - Reduced unit cost by approximately 70% - Shortened processing lead time from 20 days to 3 days *For more details, please download the PDF or feel free to contact us.

FA and industrial robot products, enlarged diameter positioning pins VRA, VRC

FA and industrial robot products, enlarged diameter positioning pins VRA, VRC

The pin has been enlarged, achieving zero gap with the reference hole! Cost reduction for correction equipment has also been realized.

The expansion diameter positioning pins VRA (standard type) and VRC (high retention type) are high-precision positioning pins where the pin diameter expands and the gap with the reference hole becomes zero. Additionally, by lining the hole, any play is also eliminated. By improving positioning accuracy on the machine side, it is possible to reduce costs for image recognition accuracy correction equipment and improve manual correction tasks. During contraction, the gap between the pin and the workpiece reference hole is increased. This large gap allows for smooth loading and unloading of workpieces and enables automation of transport by robots. 【Features】 ■ Repeat positioning accuracy of 3 μm ■ Durability of 10 million cycles (when using VRA) ■ Contraction: Easy to load and unload with a large gap ■ Expansion: No gap and retains holding power ■ Available in pin diameters starting from φ3 mm For more details, please contact us or download the catalog.
