Two-sided label manufacturing system and manufacturing method

The present invention relates to a double-sided label manufacturing apparatus and a manufacturing method, and more specifically, the upper and lower molds in close contact with the synthetic resin into the upper and lower molds, both sides can be manufactured by integrally molding without bonding the double-sided label. It relates to a label manufacturing apparatus and a manufacturing method.

In general, the double-sided label is made of a synthetic resin material and is manufactured by injection in a mold.

Such a double-sided label has a thickness of about 0.5cm and is used as a decorative member by binding to a mobile phone strap or used as a zipper handle for a bag or clothes.

1A to 1J are process flowcharts schematically showing a manufacturing process of a double-sided label that is conventionally provided.

As shown in FIG. 1A, the upper mold 10 and the lower mold 20 are manufactured such that the receiving grooves 11 and 21 and the intaglio grooves 12 and 22 are formed on one facing surface, respectively. The synthetic resin 30 is first injected into the upper mold 10 and the lower mold 20, respectively, in which the synthetic resin 30 is positioned only in the intaglio grooves 12 and 22, as shown in FIG. 1B. Will be added.
