This multi-station progressive die mass-produces automotive metal components — such as structural brackets, mounting supports, chassis reinforcements, or sensor housings. Each press stroke advances the metal strip through a series of distinct stations, so a finished automotive part is produced with every stroke at high speed.
Built with DC53 tool steel for long life and wear resistance, the die is rated for approximately 1,000,000 strokes. It runs on a 1000 kN press and is equipped with automatic feeding and take-up systems, forming 0.8 mm thick high-strength steel (HSS), SPCC, SGCC or SPHC strip at tolerances down to ±0.05 mm — and handling thicker automotive materials up to 5.0 mm.
Technical Specifications
Key Features of This Mold
1. Multi-Station Layout (Progressive Design)
The die block contains multiple distinct stations, each performing a specific operation (piercing, notching, bending, forming, cam bending). The part advances one station per stroke — ideal for high-volume automotive production with consistent quality and short cycle times.
2. Heavy-Duty Guide System
Four large guide pillars with helical springs maintain perfect alignment between the upper and lower die halves during high-speed stamping — essential for tight-tolerance (±0.05 mm) automotive parts to ensure precise formation and interchangeability.
3. Complex Inserts and Blocks
The lower die contains numerous segmented blocks and inserts. This modular design eases maintenance — if one bending or cutting section wears out, you replace only that insert, minimizing downtime and cost for high-volume automotive programs.
4. High-quality Base and Structure
The high-quality steel base plate with lifting rings can withstand the significant tonnage and vibration of a mechanical press — ensuring long-term stability when stamping high-strength steel (HSS) or thicker materials up to 5.0 mm.
5. Integrated Spring & Stripper Design
Springs and stripper plates hold the metal strip flat during cutting and strip the finished part off the punches after forming — critical for maintaining flatness and dimensional accuracy in automotive structural parts.
6. Angled Cam Bending Mechanism
A cam-driven side bending unit allows complex bends that cannot be achieved with standard vertical press motion, forming the part's side walls, flanges, or reinforcement ribs — common features in automotive brackets and supports.
Manufacturing Process
Progressive die stamping integrates multiple operations into a single die set. The process flow for an automotive part usually follows this sequence.
1. Piercing
The first stations punch pilot holes and create internal cutouts or slots in the metal strip.
2. Blanking / Notching
The outer profile of the part is partially cut to prepare for forming.
3. Bending / Forming
Successive stations bend the material into the final shape (e.g., creating mounting tabs, reinforcement ribs, or U-channels).
4. Side Bending (Cam Operation)
A cam-driven station bends the side flanges or complex angles that require horizontal movement.
5. Trimming
Any excess material or connecting tabs are trimmed off to define the final outline.
6. Separation
The final station cuts the completed part from the carrier strip.
Challenges & Solutions
1. Dimensional Accuracy and Consistency
ChallengeMaintaining the precise shape and position of the automotive part during high-speed production is difficult — parts often require ±0.05 mm tolerance and must be interchangeable.
SolutionUse high-precision guide pillars and bushings to keep the dies perfectly aligned, plus regular inspection of cutting clearances. Use CMM inspection for first-article and in-process verification.
2. Tool Wear and Life
ChallengeRepeated high-impact stamping wears the cutting edges and forming surfaces, especially with thicker steel (up to 2.5 mm) or high-strength steel (HSS).
SolutionUse DC53 or SKD11 tool steel with a robust maintenance schedule and graphite-based lubrication (up to +30% die life). Apply TiCN or TiAlN coatings to punches for added wear resistance.
3. Strip Feeding and Buckling
ChallengeFeeding the strip accurately through multiple stations without jamming or buckling is common, especially with thicker material and high-speed automotive press lines.
SolutionUse a reliable automatic feeding system with proper guiding and balanced strip tension. Servo feed systems are recommended for high-precision automotive applications.
4. Springback and Material Thickness Variance
ChallengeThe metal springs back after bending, affecting final dimensions, and different batches cause inconsistencies — critical for HSS in structural parts.
SolutionCompensate for springback at design phase using AutoForm simulation, add a sizing station to correct the shape after forming, and run regular incoming-material checks.
5. Cam Bending Accuracy
ChallengeThe side cam bending mechanism is prone to wear and alignment issues, affecting the angle and position of side flanges — flange angle tolerance is critical for fit and function.
SolutionUse high-strength cam drivers and wear plates, inspect cam contact surfaces, and adjust cam stroke for consistent bend angles. Hardened inserts (HRC 58–62) provide long-term durability.

Our Process
Inquiry → DFM Analysis → Die Design → Die Manufacturing → Sample Approval → Small Batch Order → Mass Production → Shipping.
1. Inquiry
Customer provides part drawings, material specs (e.g., SPCC, SGCC, SPHC), tolerance requirements, and annual volume for the automotive part.
2. DFM Analysis (Design for Manufacturing)
Our Engineers analyze strip layout, material utilization, bending sequence, forming defects — and automotive-specific needs such as crashworthiness, fatigue resistance and dimensional stability before make the final mold drawing, then send optimization feedback.
3. Die Design
3D CAD design of the progressive die: strip layout and station arrangement, punch and die block, guide pillar and spring system, stripper and ejection, cam bending mechanism for complex side flanges, and AutoForm simulation to predict springback and thinning.
4. Die Manufacturing
Material procurement (DC53, SKD11, etc.), CNC machining, wire EDM and grinding, heat treatment for punches and inserts, assembly and fitting, and spotting and tryout to automotive tolerance standards.
5. Sample Approval
Trial run on the press. First articles are measured and inspected using a CMM, and samples are sent for dimensional and functional approval, including PPAP documentation if required.
6. Small Batch Order
After sample approval, a small production batch verifies die stability, consistency and speed — ensuring automotive quality and cycle-time requirements.
7. Mass Production
Full-scale production with automatic feeding, producing thousands of automotive parts per hour. In-process inspection and SPC (Statistical Process Control) maintain quality.
8. Shipping
We pack, label, and ship finished parts on schedule, offering custom packaging and traceability labels for automotive supply chains.
