Vacuum Types for Industrial Manufacture

When you think of a standard vacuum, what do you have in mind? Maybe a tool that sucks dirt. But that is just one use of the vacuum process. For example, sucking air from items under airtight seal. The use of another vacuum is in the industrial manufacturing world with the concept of a vacuum deposition.

This procedure, applied by organizations like VT&C (Vacuum & Coating Technology), is used in many products. This includes alumina-coated boats and boxes, anti-contamination systems, bolts, cables, and cathodes.

Working System of Vacuum

In this process, layers of material are deposited atom-by-atom, molecule-by-molecule on a solid surface in an airless environment. Think of the transporter system of “Star Trek” minus outer space. When transferred over to the product, the thickness of these layers ranges from one atom up to several millimeters. The deposition process used depends on the materials. For instance, Physical Vapor Deposition (PVD) utilizes liquid and solid sources. Chemical Vapor Deposition (CVD) transforms various chemicals into a coating.

There are several reasons why this form of deposition we use to coat the product. One is the reduction of particle density. With evaporation, this density is smaller and provides a free path for free delivery flow. Evaporation also helps remove atoms and molecular contaminants that inhibit the production of the appropriate application layer. Low air pressure from the vacuum environment also allows controlling the composition of gas, steam, and product flow into the treatment room.

While the process of deposition seems like a good deal to take in, there are plenty of ways to determine which is useful to your organization. Research of the companies and their procedures is the most important, for if they can’t provide detailed information, then they can’t do it for you. In the end, doing your homework ahead of time will help you get the best possible company to coat and protect your products.
