Industry-Verified Manufacturing Data (2026)

Die Set

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Die Set used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Die Set is characterized by the integration of Upper Die and Lower Die. In industrial production environments, manufacturers listed on CNFX commonly emphasize Tool Steel (e.g., H13, D2) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A precision assembly of matched upper and lower dies used in forging presses to shape metal workpieces under high pressure.

Technical details and manufacturing context for Die Set

Definition
In a Hydraulic Forging Press, the Die Set is the critical tooling component that directly contacts and forms the metal workpiece. It consists of precisely machined upper and lower dies that are mounted on the press ram and bolster plate respectively. The die set determines the final shape, dimensions, and surface finish of forged parts through controlled deformation under extreme hydraulic pressure.
Working Principle
The Die Set operates by receiving the hydraulic force from the press ram, which drives the upper die downward to compress the heated metal workpiece against the stationary lower die. This plastic deformation occurs within the die cavities, forcing the metal to flow and fill the desired shape. The dies are designed with proper draft angles, fillets, and clearances to ensure part ejection and dimensional accuracy.
Common Materials
Tool Steel (e.g., H13, D2), High-Speed Steel, Carbide inserts
Technical Parameters
  • Die cavity dimensions including length, width, depth, and critical tolerances that define the forged part geometry (mm) Customizable
Components / BOM
  • Upper Die
    Mounted on the press ram, moves downward to apply forging force and form the top half of the workpiece
    Material: Tool Steel
  • Lower Die
    Stationary die mounted on the bolster plate, forms the bottom half of the workpiece and provides ejection mechanism
    Material: Tool Steel
  • Die Holder/Adapter Plate
    Interface component that securely mounts the dies to the press ram and bolster plate
    Material: Alloy Steel
  • Guide Pins/Bushings
    Precision alignment system ensuring accurate mating of upper and lower dies during each forging cycle
    Material: Case-Hardened Steel
  • Ejector System
    Mechanism (pins, plates, or hydraulic) to remove forged parts from the die cavities after forming
    Material: Tool Steel
Engineering Reasoning
200-800 MPa working pressure, 200-400°C operating temperature, 0.01-0.05 mm die clearance
Die material yield strength exceeded (e.g., H13 tool steel: 1650 MPa ultimate tensile strength), thermal stress exceeds 700 MPa at 550°C, clearance deviation >0.1 mm causes galling
Design Rationale: High-cycle fatigue from cyclic loading at 30-120 strokes/minute, thermal fatigue from repeated heating/cooling cycles, abrasive wear from workpiece material flow at 2-10 m/s contact velocity
Risk Mitigation (FMEA)
Trigger Improper die alignment causing asymmetric loading
Mode: Die cracking along grain boundaries due to stress concentration exceeding 1200 MPa
Strategy: Precision ground guide pins with 0.002 mm tolerance and hardened bushings with 58-62 HRC hardness
Trigger Insufficient die preheating below 150°C before forging
Mode: Thermal shock causing microcracks from 400°C temperature differential
Strategy: Induction heating system maintaining 200-250°C die temperature with ±5°C control

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Misalignment and binding
Cause: Improper installation, worn guide pins/bushings, or thermal expansion causing uneven clearance between punch and die components, leading to increased friction and premature wear.
Edge chipping and fatigue cracking
Cause: Cyclic loading stress concentration at sharp corners, material embrittlement from heat treatment issues, or excessive impact forces during stamping operations.
Maintenance Indicators
  • Audible grinding or scraping noises during operation indicating misalignment or worn components
  • Visible burrs or irregular edges on stamped parts showing die wear or clearance issues
Engineering Tips
  • Implement precision alignment procedures using dial indicators during installation and periodic verification to maintain optimal clearance
  • Apply specialized die lubricants and establish regular sharpening schedules based on production cycles to prevent edge degradation
