Benefits of Vacuum Metalizing

Vacuum metalizing is a process of evaporating metals in a vacuum chamber to form a desired 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 deposit aluminum on big glass mirrors of reflecting telescopes. The first step in vacuum metalizing is to choose the right vacuum level. The temperatures must be at the right standard for the metal to vaporize. The distance which metal travels needs to be increased.

Vaccum metalizing is ideal for decorating toys to give them metallic shine. The base material can either be 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 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 advantage with second surface coating is that the use of plastic as the exposed part. Aluminum is mostly used because of its conductivity, reflectivity and it is stable in air. Adding color to the topcoat can make different colors of ornaments from red, blue, pink and many others. Other metals can also be used to make different ornaments. Large surfaces can be metalized through a continuous 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 done through 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 won’t change after initial exposure.

Vacuum metalizing ensure ornaments and plastics are durable. 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 the reviews from different clients to know which companies are legit and which are fraud. Many vacuum metalizing companies are flexible to meet the demands of different clients. You can always talk to the service providers and get to know all about vacuum metalizing.
