Custom Control Cabinets Manufacturer | Precision Sheet Metal Fabrication
Rapidsheetfab is a premier custom control cabinets manufacturer and precision sheet metal fabrication partner based in Dongguan, China. Since 2015, we have been providing one-stop manufacturing solutions for industrial OEMs worldwide. From one-piece NPI prototypes to low-volume and regular repeat production, we deliver engineering-responsive, high-quality control cabinets tailored to your exact specifications.
Engineered for Industrial OEMs
We understand that a control cabinet is more than just a metal box; it is the critical housing that protects your sensitive electronics, automation controls, and power systems. We specialize in manufacturing custom enclosures, cabinets, chassis, and panels for:
Automation & Robotics
Precision enclosures for robotic controllers, PLC systems, and motion control hardware.
Industrial Equipment
Heavy-duty cabinets for machinery, process control, and factory automation systems.
Energy & Power
Robust enclosures for power distribution, inverters, and renewable energy systems.
Medical & Laboratory
Clean, corrosion-resistant cabinets for diagnostic equipment and lab instrumentation.
Electronics & Instruments
Compact chassis and panels for sensitive electronic assemblies and test equipment.
Comprehensive Manufacturing Capabilities
Our 3,500 m² facility is equipped to handle the multi-process fabrication required for complex control cabinets, eliminating the need for you to manage multiple suppliers for a single assembly.
Precision Laser Cutting & Punching
Five fiber laser cutters (up to 2000 × 4000 mm) handle large cabinet panels with ease. CNC punching adds precision holes, ventilation louvers, and formed features essential for thermal management.
CNC Bending
Seven CNC press brakes (capacity up to 230T / 3000 mm) ensure precise angles and tight tolerances (±0.20–0.30 mm) for seamless cabinet assembly.
Welding & Structural Integrity
Expert TIG, MIG/MAG, laser, and spot welding to ensure rigid frames and IP-rated seam requirements.
Hardware Insertion & Tapping
In-house PEM hardware insertion (standoffs, studs, nuts), riveting, and M2–M12 tapping for secure mounting plates and component installation.
Assembly & Preparation
Thorough deburring, grinding, brushing, and basic polishing ensure safe edges and a flawless surface for final coating.
Materials & Surface Finishing
Available Materials (0.5–12 mm)
- Steel (SPCC/CRS, Q235/Q355, SGCC/SECC): The industry standard for durable, cost-effective control cabinets.
- Stainless Steel (SUS304, SUS316, SUS430): Ideal for washdown, medical, marine, or corrosive environments.
- Aluminum (5052, 6061, 5754): Perfect for lightweight and heat-dissipating enclosure designs.
Surface Finishing
We manage top-tier surface finishing through our network of qualified partners, offering durable powder coating (standard for control cabinets), anodizing, plating, passivation, screen printing, and laser marking for your branding and labeling needs.
