Custom Tooling for Box Parts, Deep Cavity Bending, and Square Tube Forming
Custom Tooling for Box Parts, Deep Cavity Bending, and Square Tube Forming
Shengpu Tooling manufactures custom box bending press brake tooling for sheet metal box parts, deep cavity structures, closed sections, and square tube forming applications.
Box bending requires more than standard straight punches and V dies. As the workpiece is formed side by side, the already-bent flanges may interfere with the punch, die, clamping system, or machine frame. For this reason, suitable tooling design is critical for stable press brake box bending.
Product Function
Box bending tooling is designed to provide clearance, support, and positioning for multi-side bending. According to the workpiece structure, the tooling may include a gooseneck punch for box bending, segmented press brake tooling, horn punches, special lower dies, or a custom box forming punch.
For square tubes, rectangular tubes, or closed sections, Shengpu Tooling can also design a square tube bending die or square tube bending tooling to support the tube wall and control collapse, wrinkling, and springback.
Suitable Applications
Our box bending press brake tooling can be used for:
Sheet metal box parts.
Deep cavity bending.
Electrical cabinets.
Machine enclosures.
Control boxes.
Appliance housings.
Closed section forming.
Square tube bending.
Rectangular tube forming.
Custom sheet metal structures.
Why Choose Shengpu Tooling
Shengpu Tooling focuses on custom press brake tooling for non-standard sheet metal bending. We can design tooling based on your drawing, material, box dimensions, bending sequence, and machine information.
For deep boxes, closed sections, and square tube forming, our team can help evaluate interference risks before tooling production, reducing trial-and-error during bending.
Heat Treatment: Hardness and Tool Life
Through hardening, commonly HRC 47±2: a standard process for regular working conditions, balancing hardness and toughness with good general usability.
Vacuum hardening: lower deformation and better surface finish, suitable for precision punch profiles and long, narrow tooling.
Laser hardening: local surface strengthening on the working edge, improving wear resistance in high-wear areas and extending the tooling replacement cycle.
Machining Accuracy: Precision Tolerance and Segment Interchangeability
Precision grinding: parallelism can reach ±0.02 mm, helping maintain consistent bending angles along the full working length.
Segment interchangeability with joint error ≤0.04 mm: segmented tooling can be combined freely, with smooth joints and reduced risk of stepped or twisted bend lines.
Traceable dimensions: each tooling set is inspected according to the drawing, with key dimensions recorded to support rechecking.
Custom Manufacturing Capability
Gooseneck punch: throat depth, radius, angle, and working length can be customized according to the workpiece.
Square tube forming die: forming grooves can be made according to the square tube outside size, wall thickness, and section profile, with internal support options to reduce collapse.
Special forming die: negative angles, undercuts, closed structures, and other special shapes can be designed according to drawings.
Segmented combination: short, medium, and long segments can be combined freely to match different internal box dimensions.
Get a Custom Solution
If your box bending parts always hit the punch, die, or clamping system, or if your square tube parts collapse during forming, send us your drawing and forming requirements.
Shengpu Tooling will help review your product structure and provide a suitable custom box bending press brake tooling solution.
