Thick Plate Bending: When Ordinary Sheet Metal Just Isn't Strong Enough
In heavy-duty applications - think industrial #machinery frames, #construction #equipment components, #agricultural implements, or high-load structural #enclosures - designers often turn to thick plate (6mm - 20mm+). But bending these materials isn't just scaling up a regular brake press job.
Challenges we frequently solve for clients:
• Severe springback in high-strength steels
• Risk of cracking on tight radii
• Achieving consistent angles across long bends without deformation
• Balancing tonnage, tool wear, and surface quality
At Mechplus Tech Co., Ltd. , we've invested in high-tonnage CNC press brakes, custom-ground tooling sets (wide V-dies, special top punches), and experienced process engineers who understand material behavior at thickness. Whether it's:
• Cold-rolled thick plate: precise 90° structural bends
• Hardox / high-tensile abrasion-resistant steel: crack-free large-radius forming
• Stainless thick plate: corrosion-resistant enclosures with tight tolerances
…we deliver parts that drop right into assembly with minimal (or zero) secondary rework.
Recent project example:
A heavy machinery OEM needed 12 mm Q345B side frames with multiple compound bends and 8 mm flanges - tight tolerances (±0.5 mm), no visible tool marks, delivered in 3 weeks for urgent field testing. Result? They're now placing repeat monthly orders.
