Automotive Metal Stamping Manufacturing Process
Drawing Review
After partners send drawings, professionals will review them to optimize the design, ensure stamping quality, and communicate with partners regarding process analysis and material stamping properties such as elongation and yield strength.
DFM Analysis
Stamping DFM is used in the stamping product design stage to evaluate the feasibility of product stamping (including material, cracking, precision, springback) by combining stamping process and die structure, thereby reducing costs, improving yield, and shortening cycle time.
Die Design & Manufacturing
We possess the capability to design and manufacture molds, including single-stamp dies, progressive dies, drawing dies, and fine-stamping dies. Single-stamp dies are primarily used to produce prototypes and small quantities of parts, while progressive dies are used for mass production. Before formal production, single-stamp dies are used to create product prototypes, and progressive dies are used after verification and finalization.
Progressive Die Stamping
At Techsun, we don’t just stamp parts; we engineer the high-precision Progressive Die Tooling that powers smooth, continuous mass production. We design and build 100% of our progressive tooling in-house using advanced UG and Pro-E software, allowing us to control dynamic tooling tolerances within ±0.02mm.
Secondary Operations
Comprehensive Secondary Operations & Value-Added Capabilities
Beyond precision metal stamping, Techsun delivers fully integrated Secondary Operations to provide our global clients with turnkey, assembly-ready metal components. You don’t need to juggle multiple vendors; our in-house post-processing lines handle everything from high-tolerance mechanical adjustments to certified surface treatments, significantly streamlining your supply chain and reducing total procurement costs.
Inspection & Validation
After stamping production, parts are inspected according to customer drawings and specifications to verify dimensions, appearance, and functional requirements before delivery:
Dimensional verification
Appearance inspection
Assembly verification (if required)
Sample approval before mass production
Whether your project requires intricate miniaturized electronic terminals or heavy-gauge structural components, our progressive die capabilities guarantee exceptional part consistency, zero burrs, and maximized material yield across multi-million-piece runs.
Why Global OEMs Trust Our Tooling & Stamping Capacity:
• In-House Tooling Design & Maintenance: Seamless DFM review and mold modification, completely eliminating trial-and-error delays.
• High-Speed & Multi-Station Execution: Equipped with high-tonnage progressive presses to handle complex multi-bending and automatic inline tapping.
• Scalable Mass Production: Cost-effective tooling longevity engineered for consistent performance over long lifecycles.
Our Specialized Secondary Processing Capacities:
• Precision CNC Machining & Secondary Drilling: In-house CNC centers for post-stamping milling, tapping, countersinking, and tight-tolerance reaming.
• Automated Hardware Insertion & In-Die Tapping: High-speed equipment for flawless automated nut, stud, and standoff installation, alongside advanced in-die threading for maximum cost-efficiency.
• Advanced Welding & Robotic Assembly: Equipped with spot welding, TIG/MIG welding, and robotic welding cells to handle complex structural box-builds and sub-assemblies.
• Certified Surface Finishing Integration: Turnkey delivery for sandblasting, premium powder coating, anodizing, zinc plating, and specialized anti-oxidation passivation.
Why It Matters for Your Project:
One-stop responsibility. Every post-stamping process undergoes our strict internal quality gate, ensuring that multi-component assemblies align perfectly and surfaces remain 100% scratch-free upon delivery.
Quality Control for Automotive Metal Stamping
Incoming material inspection
Every time a supplier delivers materials, they undergo incoming material inspection: material thickness, surface scratches, surface dirt, and ensuring the weight matches the order.
First article inspection
Utilizing advanced Coordinate Measuring Machines (CMM), optical comparators, and automated vision sorting systems, we ensure that every critical dimension, hole positioning, bend radius, and geometric tolerance complies 100% with your exact specifications before packaging.
• 100% Blueprint Matching Guaranteed
• CPK ≥ 1.33 High-Volume Consistency
Dimensional inspection
Each product undergoes IPQC (Industrial Quality Control) inspection using calipers and 2D measuring instruments, and detailed inspection and production records are kept for customer tracking and production upgrades.
Drawing compliance
At Techsun, Drawing Compliance is our uncompromising production standard. We don’t settle for “close enough.” Every custom stamped part and sheet metal enclosure we manufacture is cross-verified against your original 3D CAD files and multi-view engineering blueprints.
Material certificates
100% Traceable Material Certifications & Compliance Reports
At Techsun, material integrity is the foundation of our manufacturing quality. We guarantee complete transparency and 100% material traceability for every project. You will never have to worry about substandard metals or compromised mechanical properties; we maintain verified, original mill test reports and internationally recognized certifications for all raw materials in our warehouse.
