Hex Nut Punch and Die Set for Cold Forming
Punch and die set for hex nut cold forming and sizing. Jungu checks bore position, punch-die alignment, corner support, material flow, and cracking pattern before quoting.

What is Hex Nut Punch and Die Set for Cold Forming used for?
A hex nut punch and die set for cold forming controls the nut blank shape, hole position, hex corner fill, and sizing stability across forming stations. The set should be reviewed together because the punch, die cavity, transfer, and blank volume interact. If the punch is slightly off-center, the hole drifts even when the die cavity is correct. If the hex corner radius or support is wrong, cracks or folds can appear during sizing. Jungu reviews the nut drawing, across-flats size, hole diameter, wall thickness, station layout, punch length, die cavity, material grade, blank size, lubrication, and photos of cracked corners, off-center holes, poor fill, or short punch life before quoting.
Common sourcing use
Hex nut forming and sizing where punch-die alignment, hole location, corner fill, and blank volume determine final acceptance.

Technical Review Scope
What Jungu checks
- Nut drawing, across-flats size, hole diameter, wall thickness, corner radius, and tolerance
- Station layout, punch length, die cavity, transfer path, and alignment method
- Blank diameter, cut length, material grade, hardness, lubrication, and forming sequence
- Failure mode: off-center hole, cracked corner, fold mark, poor fill, punch breakage, or sizing drift
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 is the hole off-center?
The issue may come from punch alignment, transfer position, blank volume, or die cavity support.
Should punch and die be quoted together?
For repeatability, yes. Reviewing only one side can miss the alignment problem.
What photos help Jungu diagnose cracking?
Send the nut corner, cracked die area, punch tip, station position, and upstream blank if possible.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
Need this tooling reviewed?
Send drawings, machine model, material, and current failure photos for review.
