Rolling plastic box mold

Outdoor equipment boxes, material boxes, and refrigerated boxes should be subject to handling and falling, rainstorm immersion, vehicle bumps, and desert exposure. The worst fear is water leakage and dust ingress at the lid joints, hinge fracture, and low-temperature embrittlement - the thin wall of the injection molding box has weak strength, poor sealing, and it is difficult to form large parts with deep cavities as a whole. The integrated molding of the rolling plastic box body is seamless, resistant to impact and drop, sealed, waterproof and dustproof, with uniform wall thickness and strong load-bearing capacity. It can be foamed for insulation and refrigeration, and the hinge is not broken. The aluminum mold cost is low, and the customization of multiple specifications is flexible.
