3. Core Advantage & Process Innovations
5-Axis High-Speed CNC Surface Contouring: Die cavities and complex 3D punch profiles are machined directly on 5-axis German CNC centers, achieving smooth mirror surface finishes without localized heat distortion.
Stress-Relief Cryogenic Post-Processing: All custom-formed punch inserts undergo multi-stage deep cryogenic freezing to eliminate internal residual stress, preventing deformation when stamping hard aerospace alloys.
Sensor-Guided In-Die Quality Monitoring: Integrated with piezoelectric force transducers and laser displacement detectors to monitor forming pressure and material seat alignment during every stroke.
4. Frequently Asked Questions (FAQ)
Q1: How do you handle custom stamping die development for proprietary non-standard drawings?
A: We execute strict Non-Disclosure Agreements (NDAs) prior to file review. Our engineering team conducts full DFM (Design for Manufacturing) and Moldflow/Forming analyses, providing detailed 3D step files and T1 inspection plans for client sign-off.
Q2: Can your custom dies handle difficult materials like Titanium Grade 5 or Inconel alloys?
A: Yes. We utilize powder metallurgy steel punches (ASP-60 / CPM-10V) combined with specialized AlCrN anti-wear coatings to withstand extreme shear pressures without punch chipping or galling.
Q3: What quality certificates are provided with the completed custom tool assembly?
A: Every die ships with a complete validation package, including CMM inspection certificates, raw material mill test reports, heat treatment hardness certifications, and sample trial inspection reports.
Q4: What is the typical lead time for custom prototype dies versus production die sets?
A: Prototype quick-turn dies take approximately 15 to 20 working days, while full-scale multi-station production dies take 30 to 40 working days depending on part complexity.
