Abstract

The invention discloses a fastening strap manufacturing method and a watch strap. The fastening strap manufacturing method includes the following steps that a film is prepared, wherein patterns or characters are printed on the film to form an ink layer; one side of the ink layer of the film is coated with a bonding agent, and drying is carried out; the film is subjected to static electricity removing; the film is put into a mold, the temperature of the film is kept being 35 DEG C to 55 DEG C, assembling is carried out, the film is injected and formed through a thermoplastic elastomer, and a fastening strap body is formed; cooling is carried out, and then an injection molding piece is taken out. According to the fastening strap manufacturing method and the watch strap, the film is subjected to static electricity removing, dust cannot be easily absorbed by the film, the surface is kept clean so that the film can be better combined with the fastening strap body, and the film and the fastening strap body are compactly connected after being combined and used for a long time; the temperature of the film is set in the specific temperature range during injection, attachment between the film and the fastening strap body can be firm, and in the following using process, the film and the fastening strap body can not be locally separated and locally layered after being continually bent and warped.

Description

technical field [0001] The invention belongs to the field of fastening straps, and in particular relates to a watch strap, a bracelet, a wearable locator phone, a manufacturing method of a fastening strap for a wearable locator, and a watch strap. Background technique [0002] In recent years, mobile wristband products such as smart watches, smart bracelets, and wearable children's phones have developed rapidly. Most of these trendy wearable products have watch functions and are fixed on the wrist by fastening straps. Synthetic resin has almost become the first choice for fastening belts (such as watch straps) of fashionable wearable products due to its rich decorability. [0003] The decoration of resin products in the early days is mainly to print or coat patterns on the surface by spraying or printing to present various patterns or colors. However, this manufacturing method is relatively complicated at first, which is not conducive to industrial mass production. In addi...
