The Hotronix Auto Clam is a self-opening ('auto clamshell') heat press machine from Stahls', a major supplier of garment-decoration equipment. This unit has a 40 x 50cm heated platen, sized for full-size prints on t-shirts, hoodies and similar flat garments. It's used to apply heat transfer vinyl (HTV), sublimation transfers, or other heat-applied graphics to fabric by pressing them under controlled heat and pressure for a set time — standard equipment for custom apparel/print shops, sports team kit suppliers and promotional merchandise businesses. The auto-open clamshell action lifts the top platen automatically once the press cycle finishes, reducing operator strain and standardising cycle times compared with a manual-release press. This is commercial equipment, not a hobbyist iron-on tool.
