Vacuum metalizing involves putting metals in a vacuum chamber to form a metalized layer. This process is mostly done on aluminum. 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 make large glass mirrors that are used in telescopes for reflection. 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. If the temperatures are not correct, the metal will vaporize well. The distance which metal travels needs to be increased.
Toys and jewelry are decorated using vacuum metalizing which makes them glow and become 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 front face is the outside part of the coated metal. This part is covered with a transparent vanish to prevent it from wear and tear. Second surface coating is the part that is used on the back of the transparent plastic like on dashboards. The benefit of the exposed plastic is that it offers protection. Aluminum is mostly used because of its conductivity, reflectivity and it is stable in air. Toapcoat vanish can include gold and silver coloring. Other metals can also be used to make different ornaments. Large surfaces can be metalized through a continuous process.
Coating can be done on one or both sides once the material is rolled over in a vacuum chamber. It is important to have large volumes of aluminum for evaporation. Vacuum metalizing has been expanded to include thick films. These coatings are corrosion resistant. Vacuum metalizing is used in EMI shielding, RFI shielding, ESD shielding and heat shielding. They are affordable and environmentally friendly as opposed to other shielding processes. EMI/RFI shielding can be used in different industries like, telecommunication, electronics, medical, military and many other industries. All metalized plastics can be recycled. The aluminum coating is oxidized as soon as it is exposed to air in the vacuum chamber. The electrical sensitivity won’t change after initial exposure.
Plastic and ornaments can last for a long time without getting damaged. Onlime marketing has made it possible for vacuum metalizing service providers to advertise their services. 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. Check whether the company is flexible to accommodate your requirements. You can always talk to the service providers and get to know all about vacuum metalizing.
