Product testing
All products undergo strict performance testing for each batch produced prior to leaving the factory. No unqualified products are allowed off the premises. Here you will see the steps of the routine inspection process.

1. Appearance inspection
1). Deviation of the outline size is not more than + 1.5mm.
2). Opening angle of the door is not less than 110°; the clearance of the door, side plate and back plate is not more than 3mm after assembly.
3). Fasteners should be firmly secured.
4). Surface of the coating layer is bright and clean, with uniform color; surface of the plastic parts is bright and clean without cracks or deformation.

2. Performance detection
1). insulation resistance: no less than 1000MΩ/500V (DC)
2). Withstand voltage: 3000V (DC) /1min, without breakdown or arcing
3). Custom-made products are tested in accordance with specified functional requirements

Customization process
1. Customers will tell us the industry they are engaged in and the specifications required. What equipment do they need, such as outdoor chassis, TV equipment cases, monitoring equipment boxes, or something else?

2. customers provide us with drawings or samples, and inform the equipment usage environment and the batch demand. Our technicians formulate the product processing plan, analyze the feasibility, and confirm specific details with customers.

3. Confirm the material and production process with customers, customers make the official order, then we begin production.
