1. Engineering & Technical Product Description
Engineered for high-density electronic assemblies and medical-grade hardware, our sheet metal stamping tooling solutions deliver ultra-tight coplanarity control and shadow-free surface finishes. Specialized in processing ultra-thin stainless steel, beryllium copper, and aluminum alloys (0.1mm - 2.0mm), our tooling system guarantees precise angular tolerances and zero-burr shearing across multi-stage automated production.

3. Key Process Features
Automated Spring-Back Angle Compensation System: Utilizes sensor-monitored pre-bending and coining stations that adjust forming angles according to raw material coil hardness variation, maintaining 90° ±0.2° bend precision without manual press tweaking.
In-Die Tapping & Riveting Module Integration: Combines high-speed thread tapping and PEM nut/standoff insertion directly within the stamping tool sequence, eliminating offline manual secondary assembly and reducing production cost per part by 40%.
Burr-Free Fine Blanking Edge Geometry: Features micro-clearance punch contours (down to 1.5% of sheet thickness) with counter-pressure pads, yielding 100% smooth shear zones suitable for direct automated soldering and hermetic sealing.
4. Frequently Asked Questions (FAQ)
Q1: How does your sheet metal stamping tool prevent scratching on pre-coated or mirror-polished stainless steel?
A: We incorporate polished PVD-coated inserts (DLC or TiCN) and urethane wipe pads. Additionally, our dies can feed protective film synchronously during the stamping stroke to isolate polished surfaces from direct metallic contact.
Q2: Can in-die nut insertion and tapping modules be integrated into a single progressive sheet metal tool?
A: Yes. We regularly build progressive dies equipped with mechanical or pneumatic servo-driven tapping heads and auto-feeding rivet modules that press nuts or studs firmly into place before the part is cutoff.
Q3: How do you control thermal expansion deformation during high-speed continuous stamping runs?
A: Our high-speed die bases feature internal cooling channels and use powder metallurgy inserts with low thermal expansion coefficients, preventing punch mis-alignment even during 8-hour uninterrupted operations at 300+ SPM.
Q4: What technical documentation and validation reports are supplied with the delivered tooling?
A: Every shipment includes a full 3D CAD step assembly file, 2D wearable parts drawings, a CMM dimensional inspection report for T1 samples, material mill test certificates, and a recommended maintenance schedule manual.
