The difficulties in manufacturing thin-walled fast food box molds mainly include the following aspects:

Mold structure design: Thin-walled molds need to take into account the shape and size of the fast food box, as well as the opening and closing method of the mold and the layout of the injection system. Since the wall thickness of the fast food box is thin, the structure of the mold needs to be designed to be stronger and more stable to ensure that the mold will not deform or break during the injection molding process.

Material selection: Thin-walled molds need to use materials with high hardness and high wear resistance to resist the high pressure and high temperature during the injection molding process. At the same time, the thermal conductivity of the material also needs to be taken into consideration to ensure that the mold can be cooled quickly and improve production efficiency.

Processing accuracy requirements: Thin-walled molds require high processing accuracy, especially the surface finish and flatness of the mold cavity, which need to ensure that no defects or flaws occur during the injection molding process. At the same time, the dimensional accuracy and fitting accuracy of the mold also need to be taken into consideration to ensure the opening and closing of the mold and the normal operation of the injection system.

Injection molding process optimization mainly includes the following aspects:

Injection molding parameter optimization: By adjusting the injection speed, injection pressure, holding time and other parameters of the injection molding machine, the best injection molding effect can be obtained. Especially in the thin-wall injection molding process, injection speed and injection pressure need to be controlled to avoid defects and imperfections.

Cooling system optimization: By designing a reasonable cooling system, the cooling speed of the mold can be accelerated and the injection molding cycle can be shortened. Especially in the thin-wall injection molding process, it is necessary to consider that the wall thickness of the fast food box is thin and the cooling speed needs to be faster to avoid thermal stress and deformation.

Mold temperature control: By controlling the temperature of the mold, it is possible to ensure that the plastic material can maintain an appropriate molten state during the injection molding process and can fully fill the mold cavity. Especially in the thin-wall injection molding process, the temperature distribution uniformity of the mold needs to be controlled to avoid thermal stress and deformation.

Mold surface treatment: Polishing, spraying and other treatments are performed on the mold surface to improve the surface finish and wear resistance of the mold and reduce the friction and wear of plastic materials during the injection molding process.

Through the above optimization measures, the manufacturing quality and injection molding effect of thin-walled fast food box molds can be improved, the defect rate can be reduced, and production efficiency can be improved....please send us a message (Email: info@ansixtech.com ) at any time and our team will reply to you within 12 hours.
