01. Die Design Capabilities

HOVOL's die design team integrates concurrent engineering workflows with world-class CAE/CAD/CAM toolchains, enabling fast iteration from concept to production-ready tooling while minimising engineering change orders.

s1

Core Engineering Competencies

  • Concurrent die engineering — design, feasibility & DFM in parallel
  • Full stamping feasibility analysis (springback, thinning, splits)
  • Press-line simulation & die synchronisation studies
  • Full-perimeter press tooling — hood, door, fender, roof, floor
  • Complex geometry: Class-A surface forming & high-strength steel
  • A-surface final approval & blue-light scanning sign-off
s2

Validation & Sign-Off

  • Virtual try-out with full press stroke simulation
  • Force/tonnage curves matched to press capacity
  • Lubrication, draw-bead & blank-holder strategies
  • PFMEA integration at process-design stage
  • OEM PPAP/PSW-ready documentation package

02. Stamping Process Planning

Rigorous process planning is applied from the earliest programme stages, delivering stable, repeatable production processes that meet OEM SPC requirements from first-off production.

Validation & Sign-Off

  • Virtual try-out with full press stroke simulation
  • Force/tonnage curves matched to press capacity
  • Lubrication, draw-bead & blank-holder strategies
  • PFMEA integration at process-design stage
  • OEM PPAP/PSW-ready documentation package

03. Die Face Engineering

Precision die face engineering is the cornerstone of surface-quality performance. HOVOL's proprietary workflows reduce physical spotting time by up to 40 %, protecting programme launch schedules and reducing tryout cost.

s1

Die Face Development

  • Addendum engineering to control springback & warp
  • Binder surface topology optimised via FEA feedbackloops
  • GD&T sealing-surface analysis (blue-light vs. nominal)
  • Thinning & wrinkle tendency mapped in simulation
  • Draft angle & parting-line negotiation with styling
s2

Business Benefits

  • Up to 40 % reduction in physical spotting cycles
  • Fewer engineering change orders post-tool build
  • Class-A surface quality achieved in fewer iterations
  • Earlier customer sign-off — protects SOP dates
  • Consistent die-face standards across global supplier base

04. Interference Checking · Surface Quality · Deformation Analysis

Precision die face engineering is the cornerstone of surface-quality performance. HOVOL's proprietary workflows reduce physical spotting time by up to 40 %, protecting programme launch schedules and reducing tryout cost.

Static Interference Check Full 3-D collision detection across all die components at BDC/TDC Zero tooling damage at first press trial
Dynamic Stroke Simulation Time-step motion study of upper/lower die through full press cycle Confirms clearance at every stroke position
Die Deflection Analysis FEA structural simulation of die casting under full press tonnage Prevents panel waviness; maintains surface tolerance
A-Surface Quality Gate Blue-light scan overlaid on nominal CAD; deviation heat-map reporting Objective, data-driven customer approval process

05. Structural Standardisation & Modular Design

HOVOL's modular die architecture aligns with leading OEM platform strategies, enabling rapid adaptation, cost sharing across programmes, and simplified maintenance for press-shop operators.

s1

Modular Component Library

  • Drawing Die — standardised addendum & binder geometry
  • Trimming Die — interchangeable blade & scrap-chute modules
  • Flanging Die — configurable cam and restriking units
  • Camming Units — unified actuation with position feedback
  • Springback Die — dedicated restrike stations
  • Piercing Die — rapid punch/die insert change system
s2

Value to the Customer
