IP67 is a widely recognized protection rating standard established by the International Electrotechnical Commission (IEC). The “6” denotes complete dust protection, meaning no dust can enter the enclosure. The “7” signifies protection against temporary immersion in water, indicating the enclosure can withstand submersion in 1 meter of water for 30 minutes without water ingress.
Ningbo Weishuo Molding and Plastic Products Co., Ltd.'s IP67 waterproof and dustproof hard box is designed, manufactured, and tested in strict compliance with this standard, ensuring every WEISHUO hard box shipped from our factory genuinely achieves this protection rating.
WEISHUO's high-strength IP67 waterproof and dustproof hard box features thickened walls beyond the standard model, with reinforced ribs added to all four corners and the base. This construction enables it to withstand greater external impacts and stacking pressures, making it particularly suitable for heavy-duty industrial applications.
In material selection, we strictly use virgin engineering PP plastic without any recycled content, ensuring long-term durability and resistance to aging. Each production batch undergoes random immersion testing, with records and video documentation retained for customer review.
