Brass Punch Pin for Metal and Auto Parts
Brass punch pin tooling for metal and automotive-style component forming. Jungu checks punch diameter, surface requirement, material pickup, alignment, coating route, and wear pattern before quoting.
What is Brass Punch Pin for Metal and Auto Parts used for?
A brass punch pin for metal and auto parts is used when brass or similar non-ferrous parts require piercing, recess forming, heading, or local shaping. The main risk is surface control. Brass can pick up on the punch, smear at the edge, or show visible marks if punch finish, lubrication, and transfer contact are not controlled. In automotive-style components, visible surfaces and repeatability are often more important than a generic punch material name. Jungu reviews the part drawing, brass grade, punch diameter, working length, station, holder fit, surface requirement, coating or polish route, lubrication, and photos of pickup, galling, scratches, rounded edges, or short punch life before quoting.
Common sourcing use
Brass and non-ferrous component forming where punch finish, material pickup, holder fit, and visible surface marks control acceptance.

Technical Review Scope
What Jungu checks
- Part drawing, punch diameter, working length, tip radius, tolerance, and contact surface
- Brass grade, hardness, surface requirement, lubrication, cleaning, and transfer handling
- Holder fit, station alignment, coating route, polish finish, and support length
- Failure: material pickup, galling, scratch, rounded edge, punch bending, or short 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
Why does brass stick to the punch?
Pickup can come from surface finish, pressure, lubrication, temperature, brass grade, or a coating route that does not match the material.
Can Jungu reduce visible scratches?
We can review punch polish, coating, transfer contact, and cleaning route, but the buyer should send real defect photos.
Is this different from steel punch pins?
Yes. Brass surface behavior and pickup risk make the finish route more important than simple hardness comparison.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
