Physical Vapour Deposition-Explanation

By | January 9, 2018

The 21st-century finishing process known as Physical Vapour Deposition (PVD) has origins which date back to the 17th century. Of course, the process of depositing thin films of atoms onto various surfaces was done in a totally different way back then. Today’s PVD machines are extremely efficient and utilized the latest technology to lay fine, unblemished finishes on metals and other products one molecule at a time. There are so many varieties that you may have a hard time deciding which one is needed for your business.

What evaporation equipment you need will depend on the finish required and the material being used. If you don’t know, then you will want to consult companies like Vergason Technology to determine what you can do for the budget you have. During the consultation, they’ll find out what you produce, the finish you desire, and the space you have for machinery. Then, they’ll present you with a number of options.

Many of these machines will have similar features when it comes to performance. For example, they will have fast processing cycles to ensure high volume throughput within a synchronous manufacturing flow when it comes to injection molding. The systems will also be able to coat a variety of metals.

When you drill down you may be shown a PVD metallizer configured for sputtering and capable of coating substrates for metals like aluminum, brass, and stainless steel. Or, you may be offered the option of a Thermal Evaporation System that applies thin metal coatings to materials for reflectivity and decoration. Another option may be a system which handles much of what a PVD unit can do except for smaller batches.

When all of the options are offered, don’t consider your current volume of finishing. Consider your projected production of the materials you finish. This may up the cost of a new unit, but you’ll be better off in the end with a machine that can handle a larger capacity instead of answering the questions of upset customers because the machine you purchased couldn’t handle the increased output. In the end, if you’re unsure, ask for an honest answer from the PVD manufacturer you choose.
