Technology / product information

Deep drawing of automotive brake clamp components using SPFC material. Progressive press processing prevents tearing and cracking while maintaining uniform thickness, enabling a stable monthly supply of 30,000 units.
Overview
This case involves brake clamp components used in automobile trunks. Since these parts are used in processes that pass and crimp electrical wires, they require high strength and stable dimensional accuracy. Mass production is carried out through deep drawing with a progressive press, using SPFC (high-tensile cold-rolled steel sheet for automobiles, JIS G 3135).
Features
- Material: SPFC (automotive high-tensile steel sheet, JIS G 3135)
- Dimensions: φ10 × 30 mm
- Thickness: t1.6 mm → wall thickness remains uniform after drawing
- Deep drawing using progressive press
- Stable supply system of 30,000 pcs/month
- Surface finish: Plating (outsourced)
Technical Innovations
- Dedicated die design to prevent cracking
- Utilized processability of high-tensile steel to maintain uniform wall thickness during deep drawing
- Proven track record of delivery to automotive parts manufacturers
Results
- Achieved both strength and processability with SPFC material
- Prevented cracking and wall-thickness variation, ensuring high dimensional accuracy
- Guaranteed stable quality and delivery for mass production
Industry Application Examples
- Automotive parts (trunk parts, brake-related components)
- Electrical harness fastening components
- Lightweight parts using high-tensile steel sheets
Leveraging deep drawing technology, we ensure stable supply of automotive high-tensile steel components.
