Bolt & Screw Forming Dies
Tungsten Carbide Dies for Engineering Forging
Drawing-based tungsten carbide dies for engineering forging and cold forming. Jungu checks forming load, material flow, carbide support, radius stress, and wear pattern before quoting.
What is Tungsten Carbide Dies for Engineering Forging used for?
Tungsten carbide dies for engineering forging are used when a custom cold-formed part needs wear resistance, dimensional stability, and controlled material flow. The correct route depends on more than carbide grade. Forming load, blank volume, radius stress, die case stiffness, shrink fit, release angle, and lubrication decide whether the die survives production. If the drawing has a sharp transition or high reduction, carbide can chip unless the support and radius are changed. Jungu reviews the part drawing, blank data, material grade, station load, cavity geometry, die case dimensions, carbide support, surface finish, and photos of cracks, sticking, wear band, or dimensional drift before quoting. The wear-band position is used to identify whether load comes from blank volume, radius, or release angle.
Common sourcing use

Technical Review Scope
What Jungu checks
- Part drawing, forming reduction, cavity radius, tolerance, and inspection method
- Blank diameter, cut length, material grade, hardness, lubrication, and surface condition
- Carbide grade, support wall, shrink fit, die case stiffness, release angle, and polish route
- Failure: edge chip, radial crack, sticking, wear band, fold mark, or dimensional 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
When is carbide suitable for engineering forging?
It is suitable when wear is dominant and support can be designed for the load. It is risky when impact or sharp transitions are unsupported.
What causes a wear band in the cavity?
Wear bands often point to concentrated material flow, poor lubrication, surface pickup, or wrong radius.
Can Jungu change the die route?
Yes. We can review carbide support, radius, shrink fit, coating, and surface finish before quoting.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
