Our business scope includes laminated steel plate business, the main agent of Japan 's gold mirror steel plate ( original import ), including NAS630 & NAS301 ( high expansion coefficient ) precipitation hardening steel plate. The product has won the pursuit of CCL / PCB customers with ultra-high hardness, extremely low surface roughness and excellent thermal conductivity. At the same time, the leveling, grinding, polishing, cutting and repairing of the pressed mirror steel plate are merged.
Precision Engineering: Every steel plate is manufactured with the highest level of precision, ensuring consistent quality and performance.
Versatility: Suitable for a wide range of applications, from PCB and CCL manufacturing to industrial machinery and electronics.
Durability: The combination of ultra-high hardness and excellent thermal conductivity ensures that our steel plates can withstand the most demanding conditions.
Customer-Centric Approach: We work closely with our customers to understand their specific needs and provide tailored solutions that enhance product quality and reduce costs.
