By structure
Take two in one for example: use seal tag molding machine to inject the seal tag at a time and then bronzing/foil stamping, and then cut the strings, finally take out the seal tags. Of course, if you have Kaikai manipulator/robot then you nearly don’t need workers, as kaikai manipulator/robot can do all these process to replace workers. Workers just pack the seal tags into the carton then it’s ok. A a worker can handle several machines at the same time! There are also three-in-one, four-in-one, all of which are first pressed out of the required pieces of granules by injection molding machine, bronzing, and then stick together.
By hot stamping
A garment seal tag has only one color, but also two kinds of hot--double gold or multi colors.
