The manufacturing details of in-mold labeling plastic barrels mainly include the following aspects:
Mold design: The mold is one of the most important links in the manufacturing process of in-mold labeling plastic barrels. The design of the mold needs to consider the shape, size, wall thickness and other factors of the product, as well as the position and shape of the label. The accuracy and quality of the mold directly affect the quality and performance of the product.
Label material selection: The selection of label materials needs to consider factors such as compatibility with plastic, shrinkage, wear resistance, temperature resistance, etc. Commonly used label materials include PE, PP, PET, etc. Different label materials have different characteristics and need to be selected according to actual needs.
Label placement: Placing the produced label at the corresponding position inside the mold is one of the key steps in in-mold labeling technology. Label placement needs to be accurate and stable, and cannot shift or warp during the molding process. There are two commonly used placement methods: mechanical placement and manual placement.
Injection molding parameter control: The control of injection molding parameters has a great impact on the quality of in-mold labeling plastic barrels. Injection molding temperature, pressure, time and other parameters need to be adjusted according to the characteristics of the plastic, mold design and product requirements. Reasonable injection molding parameters can ensure stable product molding and reliable quality.
Molding quality control: In-mold labeling plastic barrels require strict quality control during the molding process. The formed product needs to be inspected to see if its appearance, size, wall thickness and other indicators meet the requirements. Unqualified products need to be processed in time to avoid flowing into the next process.
Post-processing: In-mold labeling plastic barrels may require some post-processing procedures after molding, such as trimming, grinding, cleaning, etc. These processes need to be adjusted according to product requirements and actual conditions to ensure product quality and performance.
In short, the manufacturing details of in-mold labeling plastic buckets involve many aspects such as mold design, label material selection, label placement, injection molding parameter control, molding quality control and post-processing. The control of these details directly affects the quality and performance of the product.
