The difficulties in manufacturing in-mold labeling molds mainly include the following aspects:

Mold structure design: In-mold labeling molds need to take into account the size and shape of the label, as well as the opening and closing method of the mold and the layout of the injection system. The structure of the mold needs to be designed properly to ensure that the label can accurately fit on the product and that injection molding can be carried out smoothly.

Label positioning and fixing: The in-mold labeling mold needs to consider the positioning and fixing of the label to ensure that the label can accurately fit on the product and will not shift or fall off during the injection molding process. The way the labels are positioned and fastened needs to be designed to be stable and reliable without interfering with the injection molding process.

Material selection: In-mold labeling molds need to use materials with high hardness and high wear resistance to withstand 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: In-mold labeling molds have high processing accuracy requirements, especially the accuracy of the label’s positioning holes and fixing holes, which need to ensure that the label can be accurately positioned and fixed 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 during the in-mold labeling process, the injection speed and injection pressure need to be controlled to prevent the label from shifting or falling off.

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 during the in-mold labeling process, the fixing method of the label and the thermal conductivity of the material need to be considered to ensure that the label can be quickly fixed on the product without causing thermal stress or 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 during the in-mold labeling 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 the in-mold labeling mold can be improved, the defect rate can be reduced, and the 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.

In-mold labeling Mold Lunch box Mold flow analysis and mold design

Mold flow analysis and mold design for in-mold labeling of lunch boxes and lunch boxes is one of the key steps in manufacturing these products.

In-mold labeling mold design:

In-mold labeling molds are designed to affix labels inside the product during the injection molding process of lunch boxes and lunch boxes. During the design process, the following factors need to be considered:

Label location and size: Determine the location and size of the label to ensure that the label can be fully adhered to the interior of the product.

Label fixing method: Design a suitable fixing device to ensure that the label will not shift or fall off during the injection molding process.

Mold structure design: Design the structure of the mold according to the shape and size of the product to ensure that the label can be accurately pasted inside the product.

Mold flow analysis:

Mold flow analysis is an important step in the mold design process. Through mold flow analysis, the flow of plastic during the injection molding process can be simulated to help optimize mold design and avoid defects such as bubbles, short shots, and warpage. Mold flow analysis can be carried out using professional mold flow analysis software. According to the geometry of the mold and injection molding process parameters, the flow of plastic in the mold is simulated and corresponding analysis results and suggestions are given. Through mold flow analysis, the design of the mold can be optimized to improve product quality and production efficiency.

Mold design:

Mold design is one of the key steps in manufacturing lunch boxes and boxes. During the design process, the following factors need to be considered:

Appearance design: The appearance design of lunch boxes and lunch boxes should conform to the overall style and aesthetic requirements of the product. Factors such as the shape, curves and details of the enclosure need to be considered.

Internal structure design: The internal structure design of lunch boxes and lunch boxes should consider the use function and assembly requirements of the product to ensure the stability and reliability of the product.

Material selection: Choose suitable plastic materials, such as polypropylene (PP) or polystyrene (PS), to meet product usage requirements and cost control.

Mold manufacturing process: According to the size and shape of the product, select the appropriate mold manufacturing process, such as CNC machining, EDM and wire cutting, etc.

In summary, mold flow analysis and mold design for in-mold labeling molds for lunch boxes and lunch boxes are one of the key steps in manufacturing these products. Through reasonable mold design and mold flow analysis, lunch boxes and lunch boxes with beautiful appearance and reliable quality can be manufactured.
