As a foundry specializing in investment casting, we understand that superior castings stem from rigorous control. ISO 14001 certification validates our commitment to environmental responsibility throughout the entire production process—from raw material selection to wastewater and exhaust gas treatment—ensuring compliance with national environmental standards and enabling your products to achieve a closed-loop “green production” cycle. ISO 45001 certification demonstrates our dedication to employee safety and production standards, with a stable production environment guaranteeing consistent order delivery efficiency and casting quality.
