he first stage is to design the mold/die cast for the CNC mold engraving machine. This is the stage where we use your artwork to create a mold/die cast design. Once the vector artwork is ready, a copper plate according is loaded into the CNC engraving machine and your artwork is engraved on the copper plates by making cavities in the copper plate.
In the second stage PVC material is injected layer by layer into the cavities forming different elements of the design. Each layer is baked and then cooled and then the second layer is added and again baked and cooled. If there is a third or fourth layer the same process is repeated till the final baking of the base layer which is usually the background of the PVC patch in most designs.
In the third stage the PVC material that had been injected in the mold/die cast, after being baked off and cooled off is then manually removed from the mold/die cast in one piece to form colorful and vibrant pvc patches. Learn more about the complete pvc patch manufacturing process here.
