With marks vs. without - polyurethane makes the difference. Direct hard bending inevitably leaves die marks and scratches. The polyurethane layer conforms to the surface, distributes pressure, and protects the sheet finish. Arc bending - now with surface integrity preserved.✅ Covo Press Brake Tools Manufacturer🔥 ✅Compatible with all mainstream bending machine brands. ✅ One-step bending tools can help you improve production efficiency and speed, and also make bending work simpler and more convenient. ✅ By adding laser heat treatment to the overall heat treatment process, a hardness of 58–62 HRC can be achieved. ✅ The surface treatment employs rust prevention and sandblasting processes, significantly extending the mold's lifespan. ✅ ±0.01 mm tolerance data ✅ We can help you design custom bending methods and tools for your product and provide you with pricing information. ✅ Let us help you make your bending work more efficient, easier, and more precise. #pressbraketooling #covopressbraketool #sheetmetalbending #sheetmetalfabrication #sheetmetalbendingmachine
