Segmented Dies
Special-Shape Carbide Screw Mold and Punch Tooling
Special-shape carbide screw mold and punch tooling for non-standard fastener geometry. Jungu checks release direction, segmented structure, carbide support, and filling risk.

What is Special-Shape Carbide Screw Mold and Punch Tooling used for?
Special-shape carbide screw mold and punch tooling is used when a standard round or hex die cannot release, support, or form the required fastener geometry. The important review is the parting and support strategy. If the undercut, side wall, or asymmetric feature is ignored, the die can trap the part, crack the carbide, or form one side short. Jungu reviews the part drawing, forming sequence, release direction, possible segmented structure, carbide insert support, punch matching, material grade, and photos of poor fill or broken tooling before quoting. This page is for custom screw molds, special-shaped dies, and punch tools that need engineering review before price. We ask how the part leaves the cavity because release failure often appears as burr, drag mark, or broken insert.

Technical Review Scope
What Jungu checks
- Part drawing, undercut area, asymmetric feature, release direction, and required surface finish
- Segment layout, carbide support, die case fit, punch matching, and forming station
- Current issue: trapped part, one-sided short fill, carbide crack, burr, galling, or assembly mismatch
Why no standard price is shown
This is B2B custom tooling. A reliable quotation depends on drawing, material, size, tolerance, machine setup, annual quantity, and the mould-life issue the buyer wants to solve. Jungu quotes after technical review instead of showing a misleading fixed price.

FAQ
When is a segmented or opening-closing structure needed?
When the part shape cannot release cleanly from a one-piece cavity or the forming load needs controlled support.
Can Jungu quote from product photos?
Photos help, but special-shaped tooling still needs a drawing or critical dimensions because release direction and hidden radii affect the route.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
What should be sent first?
Send the drawing, material, machine model, tolerance requirements, annual quantity, and current tool-life problem.
Need this tooling reviewed?
Send drawings, machine model, material, and current failure photos for review.
