Vacuum coating equipment plastic surface metallization process method, vacuum coating equipment plastic surface metallization process, in our daily life, we can use a lot of plastic and plastic-made products can replace hardware metal products with the purpose, in many cases But people still prefer to use the subconscious have metallic products, for this reason, our vacuum coating machine manufacturers are generally required to use a certain surface treatment method, the electroplating process plastic surface, its plated a layer of metal (such as aluminum, zinc, copper, silver, gold, chrome) processing, and so the process. Common practice for manufacturers is to professional or vacuum plating plastic electroplating factory manufacturers for processing, handling the following two methods: conventional electroplating process is to use a method similar to the chemical plating and electroplating process water to be plastic or plastic products surface processed into metal. After the other is to use a vacuum vapor deposition apparatus in a vacuum, the metal melt, molecules or atoms to form a metal film is deposited on the plastic surface formed 5-10μm. Vacuum coating machines vacuum metallized plastic surfaces require primer with good cooperation between the thickness of the primer is usually 10-20μm, the main role is to prevent the plastic in water, organic solvents, plasticizers and other discharge affecting metal attachment. Requires high hardness coating, the primer can be modified with a plastic defects, it can provide a smooth, flat surface to facilitate the performance of the vacuum plating and plastic substrate and the plated metal firmly attached. Usually use two-component room temperature curing polyurethane and epoxy coatings, low-temperature baking of amino paint and thermoplastic acrylic paint.
What is the vacuum
Vacuum means that a given gas pressure within the space of less than the area of a standard atmospheric pressure gas state.
Vacuum is rarefied gas environment. Compared with the atmosphere it has a number of advantages, such as gas thin, less oxygen, clean environment...
