Heat press

Heat press

A heat press is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics, they can also be used to imprint designs on mugs, plates, jigsaw puzzles, and other products.

Both manual and automatic heat presses are widely available. A new style of press that is semi-automatic has entered the market as well, allowing for a manual closing process with an automatic opening. Digital technology in newer machines enables precise control of heat and pressure levels and timing. The most common types of heat press employ a flat platen to apply heat and pressure to the substrate. In the "clamshell" design, the upper heat element in the press opens like a clamshell, while in the "swing-away" design, the heat platen swings away from the lower platen. Another design type a "draw style press" allows for the bottom platen to be pulled out like a drawer away from the heat for preparation of the graphic. Vacuum presses utilise air pressure to provide the necessary force and can achieve high psi ratings.

Most heat presses currently on the market 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 tranfer 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.
