Benefits of Vacuum Metalizing
Vacuum metalizing involves putting metals in a vacuum chamber to form a metalized layer. Aluminum is most preferred during vacuum metalizing. Vacuum metalizing is used on EMI coating, vapor barriers, metallic finishes, reflective coating and many others places. Metalizing serves as decorative, functional or protective purposes. To vaporize the coating metal various heating systems are used. Vacuum metalizing is used to deposit aluminum on big glass mirrors of reflecting telescopes. When choosing proper vacuum level you have to first eliminate air in the chamber to avoid discolouration that may occur when heating metals at high temperature. For the metal to vaporize you have to set the right temperatures. Lastly there is need to increase the distance which metal travels through space.
Vacuum metalizing can be used for decorating toys and jewelry to give them a metallic sheen that is highly reflective. The original material is either plastic or metal. The surface is first made smooth without mechanical buffing to give it stunning reflection. The outside part of coated metal is called the front face. This part is usually protected with a transparent vanish because the thin decorative coating is not wear resistant. The part that covers the back of transparent plastic is called second surface coating. The exposed plastic part ensures no damage of the important parts. Aluminum is mostly proffered because it is a good conductor of heat, reflects well and is known to be stable in air. By adding color on the topcoat vanish it can appear like gold or copper. However other metals such as copper, silver, gold, chromium and cadmium are used. Metalizing of large surfaces is done through an uninterrupted process.
The material is put in a vaccum chamber and coated on either or both sides. For vacuum mechanization to be successful there needs to be large volumes of aluminum. Most recently, vacuum metalizing has been widened to include thick films. These coatings are corrosion resistant. EMI shielding, RFI shielding, ESD shielding and heat shielding are achieved by vacuum metalizing. These shielding processes are cost effective and environmentally friendly. EMI/RFI shielding can be used in different industries like, telecommunication, electronics, medical, military and many other industries. All metalized plastics can be recycled. Oxidation of the aluminum coating takes place immediately it is exposed to air in the vacuum chamber. The electrical sensitivity will remain constant after initial exposure.
Plastic and ornaments can last for a long time without getting damaged. If you are not sure where to get the best vacuum metalizing service providers, you can view different sites on the internet. Ensure you look at the profile of the company. This providers experience will give you insight on the company’s capabilities. Read different reviews from clients and check the ratings. Many vacuum metalizing companies are flexible to meet the demands of different clients. To understand vacuum metalizing better you can always talk to the experts.
