FSPR TECHNOLOGY BENEFITS
01
Low risk of cracking
02
Small minimum edge distance (12 mm)
03
Can process high-hardness materials (non-metallic carbon fiber, metals with elongation <10%, 1800 MPa high-strength steel)
04
No pre-treatment required, simple operation
05
Lower tooling replacement frequency
06
Flat surface (hot-stamped steel may have a 0.5 mm protrusion)
SPR INDUSTRY CHALLENGES
01
High risk of cracking
02
Large minimum edge distance (20 mm)
03
High hardness, thick plates, and multi-layer materials offer no advantages
04
High tooling change frequency
05
Surface protrusions affect appearance (1.5–3.0 mm)
