What are the requirements for mold in-mold labeling?

In-Mold Labeling is a technology that inserts the label directly into the surface of the product during injection molding. This technology not only provides a beautiful product appearance, but also enhances the durability and anti-counterfeiting of the product.

In-mold labeling has very high requirements for molds, and the specific requirements are introduced from four aspects:

1. Mold design

(1) Label positioning accuracy: Mold design must ensure the positioning accuracy of the label in the mold to ensure the accurate position of the label on the product. This usually requires the design of a special label positioning device in the mold.

(2) Mold surface quality: The surface quality of the mold has a direct impact on the fitting effect of the label. The surface of the mold must be smooth and flawless to ensure that the label can be tightly fitted to the surface of the product.

2, mold materials

(1) high temperature resistance: Because the in-mold labeling process is usually carried out at a higher temperature, the mold material must be able to withstand this high temperature environment without deformation or damage.

(2) Wear resistance: the mold will continue to contact the label during use, so the mold material is required to have good wear resistance to ensure the fitting quality of the label and the service life of the mold.

3, mold processing accuracy

(1) Dimensional accuracy: The dimensional accuracy of the mold directly affects the dimensional accuracy of the product and the fitting effect of the label. Therefore, the machining accuracy of the mold must be very high.

(2) Surface roughness: the surface roughness of the mold has an important impact on the fitting effect of the label. The mold surface must be smooth enough to reduce friction and resistance between the label and the mold.

4, mold maintenance and maintenance

Due to the high requirements of the mold labeling process, the maintenance and maintenance of the mold is also very important. This includes regular cleaning of the mold surface, checking the wear of the mold, and timely replacement of severely worn parts.

In general, in-mold labeling technology has very strict requirements for molds, involving mold design, material selection, processing accuracy and maintenance. In order to meet these requirements, mold manufacturers need to use advanced processing technology and high-quality materials, while carrying out strict maintenance and maintenance during use to ensure the performance of the mold and product quality.
