Welcome to LIYUAN HAINA

Liyuan Haina Rectifier
Professional manufacturer specializing in IGBT and SCR rectifiers in China, rich experience in the R&D, design and production in surface treatment industry.
Has been focusing on R&D, design, production, sales and technical services for industrial rectifier for more than 27 years. Significant achievements have been made in areas such as energy-saving synchronous rectifier, Positive&Negative pulse rectifier, electroplating surface treatments, high-power thyristor rectifier(SCR type).

Products and Exports
Our products are widely used in surface treatment, including electroplating rectifiers, anodizing rectifiers, electrophoretic rectifiers, and plasma plating rectifiers. Electroplating rectifiers include hard chrome plating rectifiers (with polarity reversing rectifiers), surface plating rectifiers (Copper, Nickel, Zinc, Gold, etc.), and PCB plating rectifiers, which are further classified into DC single and dual output rectifiers and pulse rectifiers (including single pulse rectifiers and positive & negative pulse power supplies). Anodizing rectifiers consist of aluminum anodizing rectifiers and DC/AC coloring rectifiers.
Beyond surface treatment, our rectifiers are extensively used in electrolysis, electrochemistry, oxidation, smelting, and communications, as well as industries such as steel, copper foil, water electrolysis, rare earths, special gases, aluminum, automobiles, electronics, aerospace, machinery, chemicals, and environmental protection.
The products have taken a high market share in both the electrolytic copper foil industry and the surface treatment industry. and also we are the leading pioneer to apply synchronous rectified technology into rectifier design in the world.
The PCB board electroplating industry maintain a large number of customers, especially the high-speed Positive&Negative Pulse Rectifier has broken the monopoly of imported products.
Meanwhile, the products are also exported to the United States, Canada, Britain, Italy, England, Spain, South Africa, Russia, UAE, Japan, South Korea, Malaysia and other parts of the world.
