Modern’s extrusion dies are precision-engineered tools used to shape metals, alloys, and polymers into consistent cross-sectional profiles. Designed for high-performance extrusion processes, our dies ensure superior dimensional accuracy, smooth surface finish, and long service life.
Using advanced manufacturing techniques and premium materials such as polycrystalline diamond (PCD) and tungsten carbide, we deliver reliable solutions for demanding industrial applications.
Extrusion Dies for crosshead lines require tight geometry, wear resistance, and smooth surfaces to run fast and hold concentricity. As a high-capacity manufacturer, we design and build custom extrusion tooling for insulation, jacketing, skin/stripe, and micro-bore profiles in PE, XLPE, PVC, PA, FEP, and PTFE. Size capability spans Φ0.012–Φ40.0 mm, with advanced drilling, grinding, polishing, and metrology supporting medical‑grade finishes when required.
Extrusion dies are critical components in the extrusion process, where material is forced through a die opening to form a specific shape. These dies control:
Profile accuracy and dimensional tolerance
Surface quality of extruded materials
Material flow consistency
Production efficiency and stability
Well-designed extrusion dies help reduce deformation, improve product consistency, and extend tool life.
| Type | Material | Best For | Key Advantages | Applications |
|---|---|---|---|---|
| PCD Extrusion Dies | Polycrystalline Diamond (PCD) | High precision & long-life extrusion | Excellent wear resistance High dimensional stability Smooth surface finish Long service life | Cable manufacturing Precision metal tubing Automotive components Polymer extrusion |
Our PCD extrusion dies are the preferred choice for manufacturers requiring high accuracy, consistent output, and reduced maintenance frequency.
We supply complete tip and die sets for standard and specialty configurations, engineered for stable melt flow, repeatable dimensions, and fast changeovers.
| Type | Primary use | Key benefits |
|---|---|---|
| Tip & die sets | Concentric insulation/jacketing | Matched geometries; fine adjustability |
| Pressure dies | Bonded coatings | Strong adhesion; smooth finish |
| Tube & semi‑tube dies | Loose or controlled peel jackets | Stable OD; tunable adhesion |
| Multi‑layer/co‑extrusion | Dual/triple layers; skins | Clean interfaces; layer control |
| Striping/profile & micro‑bore | Identification, features, micro‑coax | Precision bores; quick changeovers |
Matched tip/die geometry and optimized clearance enable rapid centering, minimal start‑up scrap, and stable OD/ID across polymers.
Material choice affects wear life, finish, and cost.
| Material | Wear | Finish | Use case |
|---|---|---|---|
| PCD (diamond) | Highest | Ultra‑smooth | Abrasive fillers; high speed |
| Tungsten carbide | High | Good | General‑purpose lines |
| Tool steel + CVD/PVD | Moderate–high | Low friction | Balanced performance |

Performance testing for extrusion stability
Every die is manufactured to meet industrial standards and ensure consistent performance.
Extrusion dies are used to shape materials into specific cross-sectional profiles during extrusion processes.
PCD dies offer superior wear resistance, longer life, and better precision compared to conventional materials.
Yes, all extrusion dies can be designed based on your profile shape, material, and production requirements.
Extrusion dies can be used for metals, alloys, plastics, and polymers.
Use PCD for abrasive fillers, long campaigns, or highest finish; choose carbide or coated steel for standard duties and budget goals.
Verify crosshead alignment, adjust drawdown, and match entrance and land geometry to polymer behavior. Keep lands clean.
