Project Background
Multi-Station Progressive Die,With the increasing demand for lightweight vehicles and high-volume automotive production, traditional single-operation stamping dies often face challenges such as low efficiency, high labor costs, and inconsistent part quality.
As a key manufacturing division of TTM Group, HONGXING specializes in automotive stamping die development, including progressive dies, tandem dies, and precision stamping tools. With strong engineering capabilities and advanced manufacturing facilities, HONGXING provides complete tooling solutions for global automotive customers.
In this multi-station progressive die development project, HONGXING’s engineering team optimized the stamping process, strip layout design, and die structure to achieve stable high-volume production of automotive components.
To improve production efficiency and dimensional stability, HONGXING developed a customized Multi-Station Progressive Die solution for an automotive structural component. The progressive die integrates multiple stamping processes into one tooling system, allowing continuous production from raw material feeding to finished part output.
Customer Requirement
The customer required a high-performance stamping solution for an automotive metal component with:
- High annual production volume
- Stable dimensional accuracy
- Reduced secondary operations
- Improved production efficiency
- Long die service life
The original production process required several independent dies, multiple press operations, and manual transfer between processes, resulting in increased manufacturing costs and longer production cycles.
Engineering Development
HONGXING engineering team performed a complete die development process, including:
1. Product Process Analysis
The engineering team analyzed:
- Part geometry
- Material flow direction
- Forming feasibility
- Springback control
- Stamping sequence optimization
Based on the analysis, a progressive stamping process was developed to combine multiple operations into one continuous tooling solution.
2. Strip Layout Design
The strip layout is one of the most critical steps in progressive die development.
Engineers optimized:
- Material utilization
- Carrier design
- Feeding pitch
- Station arrangement
- Scrap management
The final strip layout ensured smooth material feeding and stable production performance.
3. Multi-Station Progressive Die Process Design
The progressive die was designed with multiple working stations, including:
- Piercing
- Blanking
- Notching
- Bending
- Forming
- Coining
- Final cutting
Each station performs a specific operation while the material strip moves continuously through the die.
Multi-Station Progressive Die Process
HONGXING completed the entire tooling development process internally:
- 3D die structure design
- Mold flow and forming analysis
- CNC machining
- Wire EDM processing
- Heat treatment
- Precision grinding
- Die assembly
- Press tryout
- Dimensional inspection
Critical components were manufactured with high-precision machining to ensure repeatability and long-term production stability.
Technical Highlights
High Precision Positioning System
Pilot pins and precision guiding systems were applied to control material progression accuracy and minimize dimensional variation during high-speed stamping.
Optimized Forming Sequence
The forming process was carefully arranged to reduce:
- Material deformation
- Springback
- Cracking risk
- Surface defects
Long Service Life Design
Wear-resistant materials and replaceable inserts were adopted for high-cycle production requirements.
Project Results
After die tryout and process optimization, the progressive die achieved:
✅ Stable continuous stamping production
✅ Reduced manual handling operations
✅ Improved production efficiency
✅ Consistent part quality
✅ Lower manufacturing cost
The developed multi-station progressive die successfully supported high-volume automotive component manufacturing and provided the customer with a reliable mass-production solution.
