How to Buy a Vacuum Former

A vacuum former, sometimes called a thermoform machine, uses the negative pressure of a vacuum to mold heated plastic. Vacuum forming is used in manufacturing both products—from toys to disposable dishware to bathtubs and spas—and the plastic bubble packaging that products come in. Artists and craftspeople use vacuum formers, too, to make masks or duplicate stage props.

Instructions

Difficulty: Moderately Easy

1. Determine your needs. Vacuum formers are produced in a whole range of sizes, with numerous features suited to the particular kind of molding you'll be doing. Browse the websites of manufacturers such as Belovac to view the specifications.
2. Establish your budget. If you are a startup business, this kind of equipment purchase might be part of your initial capitalization. If you're established, and are looking to upgrade your equipment or add to your capabilities, look for vacuum formers that can take your business to the next step. Recognize that even the simplest professional vacuum formers require an investment of close to $10,000.
3. Deal online with manufacturers to purchase a new vacuum former. Electro-Forming, Brown Machine LLC and Belovac are among the leading manufacturers. Contact their customer service departments to discuss your needs and explore financing arrangements.
4. Look into the purchase of a used vacuum former. This is a particularly good option for schools and small businesses, or craftspersons with a large volume of thermoforming work. Dealers like Plastimach specialize in selling used vacuum forming machinery. You can also check online auction sites and classifieds like eBay and Craigslist, or check your local directory for business and industrial liquidators.
5. Choose a lightweight, tabletop vacuum former for home crafting. Companies like Warm Plastic offer vacuum forming tables for workshops and home use in five sizes, at reasonable prices ranging from $100 to $300. These vacuum formers are not durable enough for industrial use, but they're great for artists and model makers.
6. Buy plans and build your own vacuum former. A number of hobbyists offer plans for do-it-yourself vacuum formers online for a minimal charge. Again, this option is not suitable for industrial applications.
