Wall Thickness Specifications For Waterproof Junction Boxes Made Of Abs And Pc Materials

ABS and PC materials differ in structure. ABS housings exhibit better toughness and moldability. PC, on the other hand, possesses higher hardness and impact resistance, but is relatively brittle. A wall thickness of 2.5–3.5 mm provides sufficient mechanical strength for the waterproof junction box to withstand typical installation environments.

This thickness design ensures good dimensional stability and sealing for the waterproof distribution box. The appropriate wall thickness, combined with the built-in gasket and screw fastening structure, maintains the housing's shape and seal.

This wall thickness range demonstrates a degree of versatility for different models and sizes of the waterproof electrical box. Whether for small terminal boxes or slightly larger outdoor electrical boxes, a wall thickness of 2.5–3.5 mm meets basic structural requirements.
