Hot & Cold Runner Thin-Wall Spoon Tableware Mold

The hot and cold runner plastic cutlery spoon thin-wall mold is designed for the efficient production of lightweight and delicate plastic cutlery spoons. It combines hot runner and cold runner technologies to optimize the injection molding process and improve product quality and production efficiency. This mold is suitable for food-grade plastic materials and meets the market demand for cutlery with strict requirements on hygiene, safety and appearance. In terms of mold characteristics, the hot runner system ensures that the melt maintains a constant temperature in the runner, reduces cold material and injection pressure fluctuations, avoids short shots and flash, and improves the yield rate and surface quality. The cold runner design helps to accurately control the injection molding cycle and reduce energy consumption. Combining the advantages of both, uniform mold filling of thin-walled structures is achieved, warping and shrinkage are reduced, and the spoon wall thickness is uniform and light, which improves the comfort of use. The mold has a compact structure, uses high-hardness mold steel and high-precision processing to ensure accurate runner and gate dimensions and extend mold life. Focus on the reasonable layout of the cooling system, fast and uniform cooling, and improve production rhythm. The thin-wall design has high requirements for the mold exhaust system, and sufficient exhaust must be ensured to prevent burns and pore defects. Precautions include strictly controlling injection molding parameters (such as temperature, pressure and speed) to prevent overheating or insufficient filling of materials; regularly maintaining the hot runner system to ensure its stable operation; and selecting suitable food-grade plastic materials that meet safety standards. With rich experience and advanced technology, Jingnan Mould provides customers with hot and cold runner plastic tableware spoon thin-wall mould solutions with stable performance, high efficiency and excellent quality to meet the diverse needs of the market.
