1. Wall thickness: Generally, when designing the
New Material Waterproof Junction Box, the overall cost of the product should be considered as much as possible while meeting the product's impact resistance and resistance to glutinous change. The product wall thickness should be reduced as much as possible. The wall thickness of ABS and PC material products is generally between 2.5~3.5, the wall thickness of glass fiber reinforced polyester is generally between 5~6.5, and the wall thickness of die-cast aluminum products is generally between 2.5~6. The wall thickness of the material should be designed to meet the installation requirements of most components and accessories.
2. Selection of sealing rubber ring materials: For New Material Waterproof Junction Box products, commonly used sealing rubber ring materials are: PUR, EPDM, Neoprene, Silicon. The temperature range, tension resistance, expansion ratio, hardness, density, compression ratio, and chemical resistance should be considered when selecting the sealing rubber ring.
