LuminaCast manufactures custom tungsten carbide dies for wire-drawing plants, stamping and cold-heading shops, and tube and profile extruders worldwide. Dies are finished in-house from high-quality sintered carbide blanks — wire & sinker EDM for bore profiles, CNC precision grinding for critical faces, and PVD/CVD coating when longer die life is required.
Send a drawing, a STEP file or simply the worn die you want to replace. We quote in YG6, YG8 or YG15 (88–95 HRA) depending on the wear and impact your process generates, and advise on bore geometry and grade if the failure pattern suggests an improvement — our die failure guide shows how to read that pattern. Single replacement dies are welcome — MOQ is low and negotiable.

Four die families, all EDM-cut and CNC-ground to your specification from imported sintered carbide blanks and inspected before shipment.
Carbide drawing dies for steel, stainless, copper and aluminium wire and tube. Bore profiles — entry, approach, bearing and back-relief — EDM-cut and polished to your reduction schedule. Supplied as carbide nibs or fitted in steel cases to your specification.
Punch and die inserts for cold stamping, cold forging and cold heading of fasteners and formed parts. High-cobalt YG15 is our standard recommendation where impact loading dominates; YG8 where wear and toughness need balancing.
Extrusion dies and deep-drawing tooling for tube, profile and cup forming. Profile accuracy held by wire EDM and finish grinding for stable dimensional output over long production runs under high pressure.
Profiled carbide die blanks, sleeves and special inserts machined from your drawing or sample when a standard die format does not fit — including replacement inserts re-engineered from worn originals.
| Grade | Typical hardness | Character | Best suited dies |
|---|---|---|---|
| YG6 | ~89.5–91 HRA | Highest wear resistance, lower impact tolerance | Fine wire drawing dies, light-duty forming where abrasion dominates |
| YG8 | ~89–90 HRA | Balanced wear resistance and toughness | General wire & tube drawing dies, medium-duty stamping and forming dies |
| YG15 | ~87–88 HRA | Highest toughness, handles heavy impact | Cold heading and cold stamping dies, impact-loaded forming tools |
Typical values — exact properties vary with WC grain size, producer and batch. Material certificates available on request. Full comparison in our YG6 vs YG8 vs YG15 grade guide.
The more of this you can send, the faster and more accurate the quote. A worn die and a one-line description is enough to start.
Wherever steel dies wear out too fast — high-volume drawing, stamping and forming operations running abrasive or high-pressure processes.
| Die types | Wire & tube drawing dies, cold stamping & cold heading dies, extrusion & deep-drawing dies, die blanks / sleeves / inserts. |
|---|---|
| Material grades | YG6 / YG8 / YG15 — selected to match the wear, toughness and impact profile of your process. |
| Hardness range | 88 – 95 HRA |
| Manufacturing | Precision finishing from high-quality sintered carbide blanks: wire & sinker EDM, CNC precision grinding, PVD / CVD coating. |
| Tolerance | Down to ±0.005 mm on precision-ground surfaces. |
| Surface finish | Ra ≤ 0.2 µm achievable on ground faces. |
| Coatings | PVD & CVD (e.g. TiN, TiAlN) for lower friction and longer die life. |
| MOQ | Low and negotiable — single replacement dies welcome; samples before bulk. |
| Lead time | Samples 7–15 working days · batch 25–30 working days after approval. |
| Compliance | ISO 9001:2015, RoHS, REACH, BSCI audited. |
We are the manufacturer. LuminaCast Hardware is the export brand of Huizhou Daxin Hardware Products Co., Ltd. (USCC 91441303666518471B), founded 2007 in Huizhou, Guangdong. Carbide dies are finished in-house from sintered carbide blanks with wire and sinker EDM, CNC precision grinding and QC inspection — you order direct from the factory.
We finish-machine dies from high-quality sintered carbide blanks. In-house wire and sinker EDM, CNC precision grinding and PVD/CVD coating let us hold tight tolerances and consistent quality with shorter lead times than full powder-to-part production.
As a rule of thumb: YG6 for fine wire drawing dies where wear resistance matters most, YG8 as the balanced general-purpose choice for drawing and forming dies, and YG15 for cold heading and stamping dies that see heavy impact. Exact properties vary by producer and batch, so we confirm grade selection against your application before quoting. See the full YG6 vs YG8 vs YG15 comparison.
Yes. Send us the worn die or a physical sample and we reverse-engineer the geometry, recommend corrections to the bore profile or grade if the wear pattern suggests them, and quote a replacement. STEP, IGES or 2D PDF drawings are equally welcome.
Down to ±0.005 mm on precision-ground surfaces, with Ra ≤ 0.2 µm achievable on ground faces. Working surfaces are EDM-cut and ground to your drawing; PVD and CVD coatings (e.g. TiN, TiAlN) are available for longer die life.
MOQ is low and negotiable per item — single replacement dies are common orders. Typical sample lead time is 7–15 working days, with batch production in 25–30 working days after sample approval.
