Why Twin Sheet Thermoforming Works for Heavy-Duty Parts
If you're looking for a way to make hollow, double-walled parts without the crazy costs of blow molding, twin sheet thermoforming is probably your best bet. It's a process that doesn't always get the spotlight it deserves, but for anyone building industrial-sized gear or heavy-duty enclosures, it's a total game changer. Most people are familiar with standard vacuum forming—you heat a single sheet of plastic, suck it down over a mold, and you're done. It's great for simple covers or trays. But twin sheet thermoforming takes that concept and doubles it, literally. You're heating two separate sheets of plastic at the same time and then fusing them together while they're still hot.
