FAQs About Custom Enclosures

Sheet Metal Fabrication Process

Our in-house production line allows us to manage every step of the enclosure manufacturing process—ensuring stable quality and fast turnaround. Each project follows standard workflow guidelines to guarantee consistency from raw material cutting to final finishing.

Precision Laser Cutting for Industrial Enclosures

Laser Cutting Machine

To ensure every enclosure meets strict dimensional tolerances and a professional finish, we use advanced laser cutting technology throughout the production process. This allows us to deliver:

  • Smooth, burr-free edges

  • Precise openings for cable entry and ventilation

  • High consistency across batches

  • Faster lead times for both custom and standard designs

Whether you’re sourcing stainless steel enclosures or powder-coated mild steel cabinets, laser cutting helps us deliver reliable, scalable solutions for industrial automation, power distribution, and energy systems.

CNC Bending for Accurate and Consistent Panel Forming

CNC Bending

We use high-precision CNC bending machines to shape metal panels with tight bend angles and consistent dimensions. This ensures your enclosures are strong, structurally aligned, and visually professional.

  • Accurate bend angles for tight-fitting doors and panels

  • Uniform results across mass production

  • Compatible with stainless steel, galvanized, and mild steel

  • Optimized for both custom and standard designs

CNC bending allows us to produce durable and precisely formed components that meet the needs of modern electrical systems and industrial environments.

Professional Welding for Structural Strength and Durability

Welding

Welding is essential for creating strong, stable enclosure frames and joints. Our skilled technicians ensure every weld is clean, secure, and built to last — especially for freestanding cabinets and load-bearing structures.

  • Strong joints for long-term durability

  • TIG & MIG welding available for different materials

  • Ideal for stainless steel and mild steel assemblies

  • Supports both full-welded and modular enclosures

With precise welding craftsmanship, we guarantee enclosures that meet the rigorous demands of industrial and outdoor applications.

Surface Polishing for a Clean and Professional Finish

Polishing

We perform mechanical polishing and surface treatment to enhance the appearance and corrosion resistance of our enclosures. This ensures a smooth, clean surface that’s ready for powder coating or stainless steel presentation.

  • Deburring and smoothing sharp edges

  • Improves coating adhesion and visual appeal

  • Available for stainless steel and mild steel

  • Ideal for indoor and outdoor enclosures

Our polishing process contributes to the durability, safety, and aesthetics of every finished product.

Punching for Fast and Accurate Hole Patterns

Punching

We use CNC turret punching to quickly create holes, slots, and custom cutouts for cable entry, ventilation, and mounting hardware. This method is highly efficient for repetitive patterns and high-volume production.

  • Fast processing for standard cutouts

  • Suitable for perforation, louver, and DIN rail holes

  • High accuracy with low tooling cost

  • Ideal for mild steel and galvanized sheet metal

Punching helps reduce fabrication time while maintaining the precision and functionality your enclosure design requires.

Dip-Coat Priming & Powder Coating for Superior Surface Protection

Powder-coating

To ensure long-lasting corrosion resistance and a smooth surface finish, we apply dip-coat primer followed by electrostatic powder coating. This two-step process enhances both appearance and durability.

  • Anti-rust priming for mild steel surfaces

  • Smooth, uniform powder finish in RAL colors

  • Excellent adhesion and weather resistance

  • Suitable for indoor and outdoor applications

Our coating process ensures your enclosure looks professional and withstands harsh industrial environments.

UV Printing for Custom Labels and Branding

UV printing

We offer UV flatbed printing on metal surfaces to provide permanent, high-resolution graphics, logos, labels, and markings — without the need for stickers or engraving.

  • Durable, fade-resistant prints

  • Ideal for serial numbers, logos, warning labels

  • Works on stainless steel, coated steel, and aluminum

  • Fast, clean, and solvent-free process

UV printing gives your enclosures a professional appearance and traceable identity, ideal for OEMs and branded projects.

PU Foam Sealing Strip for IP-Rated Protection

PU foam sealing strip

We apply in-situ PU foam sealing to enclosure doors and panels to enhance dust and water resistance. This one-component polyurethane foam is dispensed directly onto the metal surface and cures into a seamless gasket.

  • Excellent sealing performance (IP54–IP66)

  • Durable, flexible, and weather-resistant

  • Applied by automated FIP(Foam-in-Place) technology

  • Ideal for outdoor, marine, and dusty environments

PU sealing ensures your enclosures stay airtight, watertight, and compliant with global standards.
