Press Brake Molds and Dies for Accurate Sheet Metal Bending
Rucheng manufactures press brake tooling, V-dies, upper punches, gooseneck punches, hemming tools, radius molds and custom bending dies for factories that need stable bend angles, controlled inside radius and long tooling life.
Choose press brake tooling from part shape, material and bend radius
Tooling selection affects tonnage, flange length, bend radius, surface marks, setup speed and repeatability. Rucheng helps match punches and dies to the press brake model, clamping system and production drawings.
CNC Bending Machine Mold
Standard and custom upper punches, lower dies, V-dies, hemming tools and segmented tooling.
Arc and Radius Molds
Radius tooling and urethane options for smooth curved bends and mark-sensitive materials.
Gooseneck Scimitar Punch
Clearance tooling for return flanges, box bending, deep channels and interference-heavy parts.
How to specify press brake molds and dies
Send the press brake model, clamping standard, material, thickness range, bend angle, required inside radius, minimum flange, part drawings and whether the visible surface must be protected. Tooling should be selected before finalizing bend programs.
Key buying factors
- V-die opening selected from material thickness, inside radius, minimum flange and tonnage limit.
- Punch nose radius matched to drawing radius, material grade and surface requirement.
- Gooseneck clearance checked against return flanges, box height and part interference.
- Segment length and tooling height matched to short parts, boxes and setup workflow.
- Material and heat treatment selected from production volume and wear requirement.
- Tooling standard confirmed for clamps, adapters, crowning system and press brake brand.
V-dies, punches, gooseneck tools and radius molds compared
A press brake tooling set usually combines several tool types. The right combination lowers scrap, protects machine tonnage and keeps setups predictable when drawings change.
| Tooling type | Best for | Main limitation | Typical buyer focus | Advantages | Next step |
|---|---|---|---|---|---|
| V-dies and standard punches | General air bending, brackets, panels, channels and common sheet metal parts | Wrong V opening can create excessive radius, high tonnage or short flange problems | V opening, punch radius, tooling height, length, hardness and clamping style | Flexible, economical and suitable for most daily press brake work | View tooling |
| Gooseneck punches | Return flanges, U-parts, box bending and parts with side wall interference | Clearance and tonnage capacity must be checked carefully | Throat depth, punch height, radius, load rating and part collision envelope | Allows deeper flanges and box parts that straight punches cannot clear | View gooseneck |
| Arc and radius molds | Large radius bends, curved panels, cosmetic parts and bump forming alternatives | Needs radius planning and may require dedicated tooling for repeat quality | Target radius, material, surface finish, tooling length and forming method | Creates smoother radius forms with fewer visible bend lines | View radius molds |
| Mark-free and urethane tooling | Stainless steel, pre-painted sheets, aluminum panels and visible surfaces | Wear, radius control and tonnage limits should be reviewed before production | Surface quality, material coating, die contact area and replacement pads | Reduces die marks, scratches and surface rework on finished parts | Surface guide |
Build the tooling plan before programming the press brake
Tooling is part of the process, not an accessory. Part drawings, bending sequence, machine tonnage and material behavior should be checked together before buying molds and dies.
V opening selection
Start with the common 6-10 times material thickness range, then adjust for material, radius and flange length.
Read tooling guideBend radius control
Match punch nose, V opening and material springback to the drawing radius and tolerance.
Use radius chartTonnage check
Confirm tooling load rating and press brake capacity before using narrow dies or high-strength material.
Calculate tonnageSequence and collision
Gooseneck tools and segmented tooling can solve return flange and box-part interference.
Plan sequenceSurface protection
Use polished tools, film, urethane pads or mark-free dies for visible stainless and coated materials.
Protect surfaceMachine compatibility
Confirm tooling standard, clamp type, crowning compatibility, shut height and adapter needs.
View press brakesTooling sets for daily bending, boxes, radii and cosmetic parts
Rucheng tooling is used in job shops and production lines where bending quality depends on repeatable tooling geometry, durable steel and the right die selection.
Electrical enclosures
Segmented punches, gooseneck tooling and V-dies for doors, boxes, cabinets and mounting plates.
Door frames and channels
Long tooling, consistent V openings and radius control for repeat frame production.
Stainless and cosmetic panels
Polished, urethane or mark-free tooling for visible parts that cannot accept die marks.
General sheet metal fabrication
Standard punches and dies for brackets, covers, flanges, trays and mixed job-shop work.
Connect molds and dies with press brake capacity and upstream machines
Accurate blanks, bend sequence, press brake tonnage and tooling geometry work together. Treat tooling selection as part of the machine line design.
Use drawings, material and bend radius to select tooling correctly
Rucheng's bending guides help buyers avoid common tooling mistakes: wrong V opening, insufficient flange support, punch interference, surface marking and under-rated tools.
Press brake molds and dies questions
How do I choose the right V-die opening?
For air bending mild steel, many shops start around 8 times material thickness, then adjust for material strength, inside radius, minimum flange, tonnage limit and drawing tolerance.
When should I use a gooseneck punch?
Use a gooseneck punch when a return flange, box side wall or deep channel would collide with a straight punch during the bending sequence.
What tooling is best for stainless steel or visible surfaces?
Use clean polished tooling, protective film, urethane pads or mark-free dies when the part surface is visible and scratches or die marks are unacceptable.
What information should I send for a tooling quotation?
Send press brake model, clamping type, bending length, material, thickness, part drawings, bend radius, minimum flange, surface requirement, segment length and expected production volume.
Send drawings and material details for a practical tooling recommendation
Rucheng will recommend V-die opening, punch type, radius, segment length, steel grade, heat treatment and tooling set layout based on your press brake and real bending parts.
