Bolt & Screw Forming Dies

HSS and Carbide Bolt Die Material Route

Bolt die tooling route using HSS, carbide, or supported hybrid structures. Jungu checks impact load, wear pattern, support structure, material flow, and target tool life before quoting.

Shop-floor checkDo not choose carbide only because it sounds harder. Send wear and crack photos first.

What is HSS and Carbide Bolt Die Material Route used for?

An HSS and carbide bolt die route is selected when the buyer needs to balance impact toughness, wear resistance, cost, and tool life. The correct material is not decided by a generic service-life claim. HSS can tolerate impact and repair better in some profiles, while carbide can resist abrasive wear when support and shrink fit are correct. If the forming load is off-center or the radius is sharp, carbide may chip; if the material flow is abrasive, HSS may wear too quickly. Jungu reviews the bolt drawing, station load, blank size, wire material, cavity radius, die case support, current wear band, crack photos, and target production quantity before quoting a material route.

Common sourcing use

Bolt cold heading where hss, carbide, or hybrid die materials must be selected against impact, wear, support, and budget.

Technical Review Scope

What Jungu checks

  • Bolt drawing, station load, cavity radius, reduction ratio, and tolerance
  • Blank size, wire material, hardness, lubrication, and surface condition
  • HSS route, carbide support, shrink fit, die case stiffness, and repair expectation
  • Failure: abrasive wear, edge chipping, radial crack, sticking, fold mark, 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.

  4. Quotation and lead time are prepared after technical confirmation.

FAQ

When is carbide not the best choice?

Carbide can be risky under impact, poor support, sharp radius, or off-center load.

When is HSS still useful?

HSS can be better when toughness, repairability, and impact tolerance matter more than abrasive wear resistance.

Can Jungu compare routes?

Yes. We can review HSS, carbide, and hybrid options using the same drawing and failure evidence.

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.
