After the MDF panels have been cut to the size of the cabinet doors, they go to high-end pre-programmed routing machines to create the respective door styles.

It then goes through another machine that clears all the dust and then lightly sprayed with a thin coat of adhesive that will help stick the thermofoil to the cabinet doors. 

Once the doors dry, they are taken to the presses, where the foil is laid over all the surfaces and sent into the press. The thermofoil only covers the front and four sides of the cabinet door, and the back is covered with a simple white melamine finish.

The press clamps down over the door for several minutes through heat and vacuum pressure, fusing the foil to the cabinet doors. The excess foil is then trimmed off each of the cabinet doors and produces a seamless surface.
