As a direct factory, we provide complete custom services from rapid prototyping to mass production, ensuring every component meets your exact structural integrity and tolerance requirements. Contact us today for a professional custom component manufacturer.
As a direct manufacturer, we specialize in high-quality custom metal electrical control box assemblies for global industrial infrastructure. We have served over 50 global clients and strictly follow Japanese quality management systems to deliver customized integrated housing solutions. Our dedicated facility ensures every custom assembly accurately matches your technical drawings through rigorous full-process inspection, providing the reliability and structural stability needed for your final system integration.
We utilize high-precision fiber laser cutting systems, CNC bending centers, high-tonnage stamping presses, and expert welding stations to fabricate complex custom electrical control boxes. Our facility transforms various metal materials into precise customized box shapes based on your technical drawings, supporting both zero-tooling rapid prototyping and high-volume cost reduction through custom progressive dies. If you are looking for a reliable custom OEM manufacturing partner for your next project, please contact us today.


We source and fabricate materials strictly according to your technical drawings and BOM to ensure optimal protection and performance. Cold rolled SPCC steel is primarily used for industrial control boxes to provide essential structural strength and excellent welding properties for durable construction. SECC and SGCC galvanized steels offer inherent corrosion resistance and EMI shielding for electronic housings. Stainless steel is selected for customized enclosures in harsh environments to ensure maximum rust prevention and long-term durability. Aluminum alloys are used for lightweight custom boxes requiring specific heat dissipation. Every custom component is processed with high-quality powder coating or plating to meet the material integrity required for your final assembly.
These are precision-engineered, customized metal systems that integrate various structural elements such as enclosures, internal mounting brackets, and pre-installed hardware like studs and nuts. As a dedicated build-to-print OEM manufacturer, we transform your technical drawings into durable customized control cabinets and electronic sub-assemblies that are ready for immediate wiring and component installation. We ensure every custom assembly is fabricated to your exact engineering specifications without any unauthorized design changes, providing a complete structural solution for your final assembly.
Our custom electrical control box assemblies are characterized by high dimensional precision and superior integration of fasteners. We specialize in providing accurate cutouts for switches, connectors, and displays while maintaining the structural rigidity of the enclosure. By ensuring tight tolerance control for all internal mounting points and expert material selection for every customized part, our components provide reliable EMI shielding and environmental protection, allowing your sensitive control electronics to function safely under industrial mechanical stress.
We follow a rigorous 8-step manufacturing flow to ensure total quality and consistency for all custom assembly orders. The process begins with a detailed technical drawing review and calculating precise bend allowances for complex multi-part box geometries. We utilize fiber laser cutting for precise hole patterns and transition to custom progressive dies for high-volume hardware stamping. Every component undergoes multi-axis CNC bending, expert welding, and automated hardware insertion for studs and nuts, followed by durable industrial coating and final quality inspection under Japanese quality management systems.
We provide a scalable custom manufacturing solution that bridges the gap between R&D prototyping and large-scale industrial assembly production. By offering zero-tooling laser cutting for initial custom batches and high-efficiency progressive tooling for mass production, we help you significantly reduce unit costs as your volume grows. Our commitment to 100% build-to-print execution and our expertise in managing complex customized hardware integration make us the reliable direct-factory partner for your global automation and electrical manufacturing needs.
Sheet metal refers to metal that has been industrially processed into thin, flat pieces. It serves as the primary structural material used to form the protective outer chassis, housing, or casing.
Sheet metal assembly combines fabricated metal parts with fasteners, welding, and other joining processes to create finished products. Learn the process, applications, pricing factors, and sourcing co
