Core making machine Features
- One line for C & Z purlins Electric roller repositioning switches profiles without roller disassembly. Quick changeover handles mixed small-batch and bulk orders.
- Progressive forming to control springback Multi-stage bending releases material internal stress. Hard chrome-coated rollers protect surface quality and guarantee stable section geometry. Finished purlins withstand outdoor wind and snow loads.
- Servo punching & flying shear cutting Servo feeding synchronizes with hydraulic punching for precise hole positions. Non-stop flying cutting boosts productivity and reduces scrap. Custom hole patterns are available.
- Rigid welded machine base Heavy welded frame suppresses vibration for long continuous operation. Premium hydraulic and electrical assemblies lower failure and maintenance work.
- Parameter recipe storage PLC saves preset recipes for different sizes. One-click recall shortens setup time for repeat production.
Forming Angle & Profile Mold Design Guidance
This Machine uses multi-step progressive angle bending to shape C and Z steel sections. Instead of heavy single-pass bending, bend angles are split across sequential forming stations to release forming stress. This avoids metal cracking, flange distortion and scratches on galvanized protective layers. Each roller pair is fine-calibrated to set flange angles and web flatness to meet unique C and Z geometry requirements. Operators adjust roller gaps and forming angles according to strip thickness and material yield strength to offset springback and eliminate common defects including profile twist and unequal flange width. Smooth transition arcs on forming dies maintain consistent dimensional accuracy during mass runs and simplify on-site bolt assembly for steel frames and PV mounting structures.
