Heavy vs thin gauge plastic thermoforming – what’s the difference?

Heavy gauge vs thin gauge thermoforming - what's the difference

The dimensional difference between heavy gauge thermoforming (sometimes referred to as thick gauge or sheet fed thermoforming ) and thin gauge (also referred to as roll fed) thermoforming may only start as a few tenths of an inch in part thickness, but the manufacturing techniques, machinery required, and scope of applications that the two are best suited for are quite distinct from one another.

Additionally, because the machinery required is unique for each process category, most plastic thermoforming manufacturers specialize in only one or the other. For instance, Productive Plastics is a custom heavy gauge plastic thermoforming manufacturer. So, you can save some time when searching for a processor if you know which category of thermoforming is the right solution for your application.

Here are the essential differences between heavy and thin gauge plastic thermoforming:
