Thermal Evaporation Coating Unit , Aluminum Metalizing Coating Machine
The machine can make very bright reflection(mirror finishing) on plastic surface.
Process of the vacuum metallizing:
In order to obtain good and strong coatings, pretreatment for the plastic substrates is necessary. We will apply the base varnish as a base before vacuum metallization.
UV painting is an alternative way to apply the base and you will get the best quality of coatings in this way. Aluminum coatings which is made by vacuum metallizing is not strong enough so we have to apply the protective topcoat. Then it will be the topcoat to contact the air and keep the vacuum metallized film inside, remain nice and long time.
For some customers, they need different colors more than silver/chrome. So they can color their products after vacuum coating.
Base coating: For most decorative and reflective applications it is necessary to apply a specially formulated primer or basecoat to promote adhesion and to provide a smooth surface, assuring a high quality surface for the metalizing or finish paint steps.
Then vacuum metalizing itself
Top coating: only when it requires, topcoat is applied to enhance, moisture, abrasion, and chemical resistance.
