Controller Enclosure Manufacturing Case


Product Overview
Product name: Controller Enclosure 

Material: cold-rolled steel (SPCC) 

Surface treatment: Coating light blue

Assembly service: Required.

QTY: 100pcs

Requirements:  Free of burrs and stains, excellent wear resistance, Corrosion resistance, Corrosion resistance

Manufacturing Process

1. Laser Cutting - Precision cutting SPCC sheets based on approved CAD files.

First-article inspection using for dimensional verification

Periodic in-process checks with calibrated measuring instruments


2. CNC Bending - Press brake forming for structural integrity.

Programmed bending sequences create precise 3D structures

Bend angle verification with digital protractors

Sample validation against 3D models before batch production


3. Welding - Secure joining of components.  

MIG/TIG welding ensures strong, continuous seams

Visual inspection for weld consistency and penetration


4. Grinding & Deburring - Smooth edge treatment.

Comprehensive grinding eliminates sharp edges and creates seamless transitions

5. Surface Preparation & Powder Coating.

Chemical pre-treatment (degreasing, phosphating) enhances adhesion

Electrostatic powder coating application

Quality control:

   Cross-cut adhesion testing per international standards
   Coating thickness verification with digital gauges
   Color matching and finish inspection under controlled lighting

6. Final Assembly & Packaging
Complete component integration following assembly drawings
Functional testing of all interfaces and mounting points
100% final visual inspection for cosmetic defects
Order verification against shipment specifications.
