Heat presses currently use an aluminum upper-heating element with a heat rod cast into the aluminum or a heating wire attached to the element. For high-volume operations involving the continuous imprinting of items, automatic shuttle transfer presses are used. The substrates to be imprinted are continuously loaded onto the lower platen and shuttled under the heat platen, which then applies the necessary heat and pressure. The pattern is printed in sublimating ink on sublimating paper which allows the pattern to transfer. You can get some highly effective patterns and great effects using this technique. Heat presses can also use a rubber roller to print the curved surface products like cap, pan, cup and so on.
