Header Punches & Punch Pins
Customized Cold Heading Punch Tooling
Drawing-based cold heading punch tooling for custom fastener forming. Jungu checks station load, punch nose radius, material route, coating, alignment, and breakage pattern before quoting.
What is Customized Cold Heading Punch Tooling used for?
Customized cold heading punch tooling is used when a standard punch shape cannot form the required head, recess, or special fastener geometry. The main review point is not only the punch profile. Breakage often comes from station misalignment, unsupported nose length, sharp radius, material hardness, coating mismatch, or a die cavity that does not release the formed part cleanly. Jungu reviews the finished part drawing, punch drawing if available, machine station, fastener material, forming sequence, punch nose radius, coating route, and photos of broken tips, bending marks, galling, or poor fill. This page is for buyers who need an engineering route for a custom punch rather than a simple replacement by name. When the same punch fails repeatedly, we compare fracture position with machine alignment and finished-part defects before copying the old geometry.
Common sourcing use
Custom head forming, recess forming, and special fastener geometry where punch alignment and nose support control tool life.

Technical Review Scope
What Jungu checks
- Finished part drawing, punch profile, nose radius, recess depth, and tolerance zone
- Machine station, punch holder, alignment, forming sequence, and mating die cavity
- Workpiece material, wire hardness, lubrication, coating route, and target output
- Failure mode: tip breakage, bending, galling, poor fill, head eccentricity, or short punch life
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
Can Jungu copy a broken punch?
A broken punch helps, but the station and part drawing are needed because the original may already include a design mistake.
Why does a punch break at the nose?
Common causes are sharp radius, long unsupported nose, misalignment, hard material, poor coating route, or die cavity release issue.
Should the punch be carbide or tool steel?
Jungu decides after checking impact load, profile size, support length, and wear pattern; harder material is not always safer.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
