This page explains how Die Holder is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A mechanical component in an extrusion press that securely clamps and positions the extrusion die during the metal forming process.
Technical details and manufacturing context for Die Holder
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Clamping Force | 150–300 kN | Must exceed extrusion force to prevent die slippage |
| Die Diameter Range | 100–400 mm | Standard sizes for common extrusion presses |
| Die Thickness Range | 20–80 mm | Accommodates standard die plates |
| Maximum Operating Temperature | 450–500 °C | Above this, material strength degrades |
| Parallelism | ≤0.02 mm | Ensures uniform clamping and die alignmentISO 1101 |
| Surface Roughness | Ra 0.8–1.6 µm | Critical for sealing and wear resistanceISO 1302 |
| Material Grade | 42CrMo4 | High-strength alloy steel for hot workDIN EN 10083 |
| Hardness | HRC 38–42 | Balances toughness and wear resistanceISO 6508 |
| Weight | 50–200 kg | Depends on size and clamping force |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 1500 MPa (217,500 psi) clamping force, 100 MPa (14,500 psi) hydraulic pressure |
| other spec: | Die diameter range: 100-800 mm (4-32 in), alignment tolerance: ±0.05 mm (±0.002 in), clamping mechanism: hydraulic or mechanical wedge |
| temperature: | Ambient to 500°C (932°F) for standard models, up to 800°C (1472°F) with special alloys |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The clamping force typically ranges from 150 to 300 kN, but it must exceed the extrusion force to prevent die slippage. Confirm the required force for your specific press and application with the manufacturer.
The die holder accommodates dies with diameters from 100 to 400 mm and thicknesses from 20 to 80 mm. These are standard ranges; verify compatibility with your die dimensions.
Common materials include alloy steel and tool steel, with a typical grade of 42CrMo4 (DIN EN 10083). The hardness is usually HRC 38–42. Confirm the material grade and heat treatment with the supplier.
Parallelism is specified per ISO 1101 (≤0.02 mm), and surface roughness per ISO 1302 (Ra 0.8–1.6 µm). These standards are verification references; ensure the product meets them for your application.
