Feature 1: Concise The whole 3D vacuum heat press machine with compact and practical inner structure adopts special material which is adiabatic and uninflammable. And the the outer appearance is fashion and concise. Feature 2: High Efficiency A big oven space, nonparallel working efficiency of printing 12 mugs at one time, equaling 12 mug heat press machines. Feature3: Intelligent Use friendly desktop design, simple fresh-hand lead in and control just with temperature and time setting. No extra manipulation needs for the whole printing process but only putin and take-out. When the cover is closed, the machine will automatically extract air, countdown and heat. When the printing is finished, the machine will automatically suck air. Feature4: Delicate Heating area is enlarged with the bump dots design; and temperature of each point in the oven is even with the aluminum alloy heating and the far infrared radiation coat. Printing comes out in a more clear and vivid way. Feature5: Compact 108 degree upward clamshell design that is compact and simple to operate and also saving space. Feature6: Environmental Friendly Highly activated carbon air filter is equipped in the sublimation 3 d press machine, effectively filtering the poisonous smell produced during printing and protecting users? safety. Feature7: Safety Double-circuit design guarantees temperature control. When malfunction occurs in one circuit, the other temperature controlling circuit activates automatically. The machine will automatically shut down after 15 minutes? idle running, making it safe and reliable. This sublimation vacuum transfer machine has applied for CE/UL certificate. The 3D vacuum heat transfer machine is multifunctional for both flat items and curved items, such as T-shirt, pillowcase, tile, mouse pad, glass, crystal, plate, mug, iPhone cover, iPad cover, etc.
