Header Punches & Punch Pins
Custom Ball Head Punch Tool Pin Punch
Custom ball head punch tool pins for special head forming and profile control. Jungu checks radius transition, punch alignment, impact load, and polishing requirement.
What is Custom Ball Head Punch Tool Pin Punch used for?
A ball head punch tool pin is used when the formed part needs a rounded head, ball profile, or smooth transition that a flat punch cannot create. The common failure is not only tip wear; the transition between ball radius and shank can concentrate stress, especially when the material is hard or the punch is slightly misaligned. Surface finish also matters because a rough ball head can drag material and leave marks on the formed part. Jungu reviews the ball radius, head height, shank diameter, punch length, machine station, fastener material, coating route, polishing requirement, and photos of worn tips or cracked transitions before quoting. We compare the formed surface mark with the punch surface because polishing, radius, and alignment leave different evidence.
Common sourcing use

Technical Review Scope
What Jungu checks
- Ball radius, head height, shank diameter, transition radius, tolerance, and surface finish
- Punch length, station alignment, impact load, material grade, coating, and polishing route
- Current issue: cracked transition, flattened ball head, surface drag mark, galling, or bending
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
Why does the transition area crack?
The load changes direction around the ball-to-shank transition. A small radius, hard material, or alignment error can concentrate stress there.
Is mirror polishing needed?
It depends on the visible surface requirement and material flow. Smooth finish can reduce drag marks but does not replace correct geometry.
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.
