Disposable turnover box mold is specifically designed for thin - walled PP/HDPE injection molding, aiming for "lightweight, fast, and cost - effective". The cavity is made of highly polished P20 or aluminum 7075. The mold frame follows the simplified LKM standard. The overall hardening is 32 - 35 HRC. The surface is hard - chrome - plated with a hardness of no less than 700 HV, which is rust - proof and easy to clean. The wall thickness is controlled at 1.2 - 1.8 mm, and the box weight is only 40 percent of that of a standard box. It can be folded or flat - stacked, eliminating the need for sorting during recycling. The mold adopts a 4 - to - 8 - cavity hot - runner stacked layout, combined with needle - valve gates. The weld line strength is no less than 60 percent. The molding cycle is no more than 8 seconds. The daily output can reach 30,000 pieces. The cooling system uses 3D - printed conformal cooling channels, with a temperature difference of no more than 3℃, shortening the cooling time by 30 percent. The ejection system is equipped with ejector plates and air valves to achieve zero ejector pin marks, ensuring a clean appearance of the box. The mold life is 100,000 - 200,000 moldings, meeting the needs of disposable e - commerce, fruit and vegetable, and express packaging. It is the core production tool for low - cost, high - efficiency, environmentally - friendly, and recyclable logistics carriers.
