A: All of these terms can be used to describe the same process, with vacuum metallizing being a more specific case. Within the confines of a chamber which has had most of the air removed, metals or other materials are heated until they vaporize. This vapor travels about the chamber and condenses on surfaces within the chamber, forming a thin film.
A: Many metals, compounds, chemicals, and alloys can be evaporated and/or deposited. The material will dictate which of the techniques listed above should be used. Please contact us for details on specific materials.
A: Ask us! Chances are that we can help, even if you don’t see the item on our site.
A:We understand the rapid pace of business these days. Our goal is to return a quotation to you within 24 hours of receiving your request. You can help speed this process by tolerancing prints, indicating purchase quantities, and specifying material compositions in your inquiry.
A: In order to provide you with the most timely service and most accurate information, all inquiries are handled directly by our in-house staff. If your situation requires a visit to your facility, we will gladly arrange for one of our staff to meet with you.
