Heat transfer machine does not print the design itself. It transfers a pre-printed heat transfer film onto a plastic product using heat and pressure. Here is the step-by-step process:
1. Set the machine parameters
Adjust temperature, pressure, and speed according to the heat transfer film and plastic material, such as PP or PE.
2. Load the heat transfer film
Mount the pre-printed film roll onto the machine and thread it through the heating zone. The printed side should face the product surface.
3. Position the product
Place the plastic product onto the printing mold or fixture so it is securely held and correctly aligned.
4. Start the transfer cycle
The heated silicone roller presses the film against the product surface. The product rotates or moves so the design covers the required area.
5. Activate the adhesive and release layer
Under heat and pressure, the film’s release layer activates and the adhesive layer softens, allowing the printed design to separate from the PET carrier film.
6. Transfer the design
The printed pattern bonds permanently to the plastic surface. The silicone roller ensures even pressure and consistent heat distribution.
7. Peel off the carrier film
After a short cooling period, the PET carrier film is peeled away, leaving the design on the product.
8. Inspect the finished product
Check color accuracy, adhesion, surface smoothness, and whether there are bubbles, wrinkles, or missing areas.
In short, the heat transfer machine uses a heated silicone roller to press pre-printed film onto plastic products, transferring the design through heat and pressure.
