Here is the whole process of making the pvc labels,
1.Mixing machine is for mixing the liquid pvc and colors,
2.Vacuum Machine is for removing the bubble of liquid pvc material,
3.Dispensing Machine is for filling the multi colors on the mold with liquid pvc,
4.PVC production line if for drying and baking the liquid pvc on the mold,
5.Feeding machine is for filling the basic labels
