Do you want to manufacture fast food boxes to meet market demand?

We are a professional manufacturer of thin-walled food container molds. The thin-walled lunch box molds we manufacture are round, square, oval, the number of cavities ranges from 2 to 12 cavities, and the minimum wall thickness can reach 0.38mm. While ensuring the hardness of the lunch box, the wall thickness is uniform.

A good mold design is a prerequisite for the manufacturing food box molds. We have a senior mold design team to analyze the mold structure and product structure in all aspects, including demolding slope, product surface miniature, pouring system, exhaust system, cooling system, etc. The most important and most prone problems of these molds are repeated tests during mold structure design.

The design of the cooling system is a relatively complicated task. We need to consider the cooling effect and the uniformity of the cooling, and the influence of the cooling system on the overall structure of the mold. Determine the specific location and size of the cooling system. Also we need think about the cooling on moving plates and inserts; the cooling of side sliders and side cores; the design of cooling elements and the selection of cooling standard elements. We analyze these series of problems during the mold design. By inlaying beryllium copper on the mold to achieve the rapid cooling effect, the cooling time during injection was reduced, the production efficiency of the product was improved, and the production cost was greatly reduced.

As we all know that thin-walled products have higher requirements for exhaust. In addition to avoiding surface burns and insufficient injection volume, excellent exhaust can also eliminate various defects of the product and reduce mold pollution. We have rationally designed the exhaust method and size of the exhaust slot to reduce the injection pressure and injection time, making the plastic parts from difficult to easy, and reducing the energy consumption of the machine.

Fast food box molds are generally recommended to use S136 or H13. After quenching, the hardness of the core and cavity can reach HRC45-52, the life of the mold can be improved, and it is suitable for long-term efficient and stable operation.
