First, we need to figure out what is sublimation transfer oven.
The sublimation transfer oven system is specially designed to transfer the grain pattern of polyester film to aluminum profile or plate surfaces, usually with a wood or marble effect on a single surface. The profiles or sheet parts must have been previously coated with special primer powder coating. The transfer process from the film to the aluminium profile or sheet surfaces takes place at the gelling temperature of the primer powder coating.
Aluminum profiles previously coated with primer powder coating and bagged with polyester transfer film are placed one by one on the carrier and mounted on special vacuum nozzles on both sides of the carrier. By using the vacuum valves at both sides, the air inside the bags is sucked out and the entire film is allowed to contact the profile surfaces. All profiles are vacuumed one by one in the same way. After the Start button is pressed and the carrier trolley is fed into the oven.
As long as the carrier trolley is in the oven, the vacuum pump works continuously to ensure maximum efficiency in the transfer. When the transfer from the polyester film to the profile surface is realized, the carriage automatically exits the oven. The compressed air system starts to work and presses air into the bags to separate the polyester film from the profile surfaces. Afterwards, the polyester film is separated from the profile surfaces by the operator and the final product is obtained.
As standard, the transfer furnace is designed only for the transfer process on aluminum profiles or similar materials. There is an apparatus with a silicone membrane system vacuum frame that oven manufacturer have specially designed for transfer to products such as aluminum plates or steel doors with flat surfaces.
The silicone membrane can be in blue and white. Blue silicone membrane is 0.8mm thickness, white silicone membrane is 1.2mm thickness. And most customer prefer 1.2mm thickness white silicone membrane according to the order data of previous years.
