Transformer Coated Copper Sheet | Precision Stamped Components for Electrical Equipment
10+ Years Trusted Industrial & Trading Partner
We are a professional industrial & trading enterprise with over 10 years of precision stamping experience, specializing in high-performance transformer coated copper sheets. One-stop solutions from design optimization, die development, mass production to global shipping, serving transformer and electrical equipment manufacturers worldwide.
Core Stamping & Product Advantages
50+ CNC precision stamping machines (60–800 tons) ensure high-precision forming (tolerance ±0.02–0.2mm) without damaging the copper sheet coating.
High-purity copper base (C11000/C12200) with professional insulation coating (polyimide, epoxy resin) for excellent conductivity (≥98% IACS) and electrical insulation, compliant with electrical safety standards.
Strict coating integrity testing and stamping process control, ensuring corrosion resistance, high-temperature stability (up to 180℃) and long service life in transformer working conditions.
