Our "Zero Defect" commitment has elevated our first-pass yield to 99.5%. Whether for EV battery packs or precision electronics, we deliver reliability you can measure.
Every custom stamped metal part is produced under strict quality management systems certified to ISO 9001, ISO 14001, and IATF 16949.
We maintain full process traceability from raw materials to finished products, ensuring consistent dimensional accuracy and reliable production performance.
Frequently Asked Questions
We have extensive experience processing a wide range of metals, including but not limited to: Copper, Brass, Phosphor Bronze, Beryllium Copper, Stainless Steel, Aluminum alloys, Cold Rolled Steel (SPCC), and various pre-plated materials. We can provide professional material recommendations based on your specific application requirements.
Relying on our precise mold design and high-precision stamping equipment, we can generally control dimensional tolerances between ±0.01mm and ±0.03mm. For certain critical dimensions, we can achieve strict tolerances up to ±0.005mm, depending on the part geometry and material characteristics.
The design and manufacturing cycle for molds depends on their complexity. Generally, simple progressive dies take about 20–30 days, while complex, high-precision multi-station molds may require 35–45 days. We conduct rigorous mold trials (T1–T3) and sample approvals before mass production.
Yes, we provide a complete full-service workflow: from initial DFM (Design for Manufacturability) analysis, mold design and fabrication, rapid prototyping (T1 samples), and sample validation, to large-scale automated mass production, surface treatments (plating, cleaning, polishing), and global logistics.
Our quality management system strictly complies with international standards. Our factory is certified to ISO 9001:2015 for quality management and ISO 14001:2015 for environmental management. For automotive clients, we strictly implement IATF 16949 processes to ensure exceptional consistency and reliability across every batch.
