Power Distribution Cabinet Metal Fabrication

Product Overview

 

Welding Operations: Employs Yaskawa and Panasonic robotic welding systems to join formed sheet metal panels. The automated process produces consistent seams that define the structural framework of the enclosure.

 

Mechanical Assembly: Integrates functional hardware into the fabricated metal shell. This process involves the installation of doors, hinges, standard or custom locking mechanisms, and internal mounting plates as specified in client drawings.

 

Sealing and Finishing: Prepares the enclosure for specific operating environments. This stage includes applying sealing gaskets for ingress protection and utilizing an automated powder coating line for surface coverage.

 

Consolidated Manufacturing: Executes laser cutting, CNC bending, welding, painting, and hardware assembly within a single facility. This single-source approach coordinates the entire production cycle from flat sheet metal to the final assembled cabinet.

Frequently Asked Questions

 
What welding techniques do you use for sheet metal enclosures? +

We utilize TIG and MIG welding for manual operations, and Panasonic/Yaskawa robotic welding cells for batch production. Spot welding is also applied for internal mounting plates and brackets.

Can you manufacture enclosures to meet specific IP protection ratings? +

Yes. We control the enclosure's sealing performance by applying specific welding techniques and installing custom rubber or silicone gaskets based on your required IP rating (e.g., IP54, IP65).

Do you procure and install the mechanical hardware, or do we need to provide it? +

We provide complete assembly. We can procure standard hardware (locks, hinges, latches) according to your Bill of Materials (BOM), or you can consign the specific components to our factory for installation.

How do you inspect the quality of the welded seams? +

Welded joints undergo visual inspection for surface defects. For projects with strict requirements, we perform dye penetrant testing to verify seam integrity before moving the parts to the powder coating line.

How are fully assembled metal cabinets packaged to prevent damage during shipping? +

Assembled units are packed using edge protectors, custom foam inserts, and PE film. For international freight, the products are secured in custom wooden crates or onto export-grade pallets.
