Precision Custom Metal Stampings for High-Volume Production
When your assembly line demands millions of parts with zero dimensional drift, standard fabrication falls short. We engineer progressive and single-stage tooling for SPCC, SUS304, and aluminum alloys, delivering ±0.01mm tolerances directly from our 45T-400T presses in Dongguan.
Engineered for Material Versatility and Structural Integrity
Different industries require specific tensile strengths and surface behaviors. We match your cabinet drawings and mounting requirements with the exact stamping process needed, avoiding material waste and secondary machining.
Carbon & Cold Rolled Steel
Utilizing SPCC, SECC, and SPHC from 0.5mm to 8.0mm. Ideal for heavy-duty internal brackets and chassis where structural rigidity is non-negotiable. Compatible with zinc plating and powder coating for rust prevention.
Stainless Steel (SUS)
Processing SUS301, SUS304, and SUS316. We manage the high spring-back rates of stainless steel through precise progressive die design, ensuring flat mating surfaces for medical and food-grade enclosures.
Aluminum Alloys
AL5052 and AL6061 processing for lightweighting projects. We prevent surface galling during the drawing process and provide anodizing-ready surfaces, crucial for EV components and heat sinks.
Copper & Brass
High-speed stamping of Beryllium Copper and Phosphor Bronze for electrical contacts and terminals. We control burrs to under 10% of material thickness to ensure stable interface compatibility.
Solving Complex Procurement Constraints
We don't just supply metal parts; we resolve engineering bottlenecks. See how our stamping solutions address specific structural, environmental, and assembly constraints in real-world applications.
EV Battery Enclosure Brackets
The Constraint: Automotive procurement teams face strict weight reduction mandates while requiring brackets that can withstand constant high-frequency vibration without fatigue cracking over a 10-year lifespan.
Our Solution: We utilize 2.0mm AL5052-H32 aluminum, formed through a 5-stage progressive die. We incorporate stamped reinforcing ribs into the open-frame structure and maintain a ±0.05mm tolerance on the mounting holes to match the main chassis perfectly.
The Benefit: Reduces part weight by 40% compared to traditional steel brackets, cuts assembly line fitting time by eliminating manual hole adjustments, and achieves zero fatigue failure in 500,000-cycle vibration testing.
1U Server Chassis Panels
The Constraint: Data center hardware requires maximum internal volume for electronics within a standardized 1U form factor. The enclosures must dissipate high heat loads while maintaining structural rigidity against rack mounting stresses.
Our Solution: A hybrid stamping and sheet metal approach using 1.2mm SECC steel. We stamp high-density ventilation louvers directly into the panel in a single press stroke, avoiding the slow cycle times of CNC punching. The design includes pre-tapped interface compatibility for standard motherboard standoffs.
The Benefit: Increases airflow area by 22% compared to standard drilled holes, prevents cabinet sagging under heavy component loads, and lowers unit cost by 18% at a 5,000pcs MOQ due to the high-speed stamping process.
High-Cycle Electrical Terminals
The Constraint: Connecting devices require micro-terminals that provide stable electrical conductivity in humid environments, while surviving thousands of insertion cycles without losing clamping force.
Our Solution: High-speed stamping of 0.2mm Phosphor Bronze using carbide tooling to ensure burr-free edges. We manage the mass production stability of the complex bend angles, followed by selective gold plating strictly on the contact area to save material costs.
The Benefit: Ensures stable touch accuracy and signal transmission, avoids oxidation-related maintenance problems in the field, and allows for rapid sample approval within 12 days.

Mass Production Stability Guaranteed by Data, Not Words
Tooling wear is inevitable in high-volume metal stampings. The difference lies in how it is monitored. We don't wait for a batch to fail; we measure tooling degradation proactively.
-
First Article Inspection (FAI) Every new tooling setup undergoes strict FAI using our Hexagon CMM to verify all mounting holes and bend radii match your 2D/3D drawings before mass production begins.
-
In-Process Optical Sorting For critical small components like electrical contacts, we employ automated optical inspection (AOI) to detect burrs or deformations, ensuring batch consistency.
-
PPAP Documentation For automotive and medical clients, we provide Level 3 PPAP documentation, including CPK data, control plans, and material certifications (RoHS/REACH).
