1. Technical Profile & Product Capability
Designed for continuous high-throughput manufacturing, our progressive stamping die systems enable multi-operation forming-including piercing, blanking, deep drawing, and flanging-within a single automated press cycle. Optimized for automotive chassis structural parts and EV powertrain components, our tooling guarantees pitch accuracy of ±0.005mm and extended run stability under extreme SPM speeds.

3. Key Process Features
Integrated Strip Pilot Alignment: Incorporates hardened pilot pins with micro-taper guides at every station to maintain exact coil orientation, eliminating cumulative strip pitch deviation over long production runs.
Quick-Change Modular Insert Architecture: Designed with independent sub-plates and wedge-locking blocks that allow rapid replacement of high-wear punch tips directly on the press without disassembling the main die base.
Controlled Clearance Shearing Profile: Features specialized cutting edge radii that reduce material burr heights to under 5% of sheet thickness, satisfying strict automotive assembly and welding standards.
4. Operational Frequently Asked Questions (FAQ)
Q1: How do you prevent strip jam and buckling during high-speed progressive die operations?
A: We integrate floating strip lifters, spring-loaded guide rails, and real-time optical mis-feed sensors that immediately trip the press emergency stop if the material fails to advance to the exact pilot position.
Q2: What is the estimated wear life of your progressive die punches when stamping high-strength steel?
A: For high-tensile steels (e.g., DP780), our DC53/TD-coated punches achieve 150,000 to 200,000 strokes between regrinds, with an overall tool lifespan exceeding 3,000,000 total strokes.
Q3: Can your progressive tooling perform both stamping and in-die part stacking/interlocking for motor laminations?
A: Yes. Our motor lamination dies feature automatic hydraulic or pneumatic die-bottom indexing systems that interlock, skew, and count rotor/stator sheets directly inside the tool before ejection.
Q4: How do you ensure tool alignment during initial installation on our stamping presses?
A: All die sets are fitted with precision guide posts, ball cages, and locating keyways. We also provide full press shut-height parameters, strip feeding line heights, and trial video documentation prior to delivery.
