Thin-Gauge Thermoforming Machines: Applications and Advantages
Thin-gauge thermoforming machines are specialized tools designed for shaping thin plastic sheets into a wide variety of products. These machines are widely used in industries such as food packaging, retail, medical, and consumer goods, where lightweight and cost-effective solutions are essential. In this article, we’ll explore the applications, advantages, and materials used in thin-gauge thermoforming machines.
What Are Thin-Gauge Thermoforming Machines?
Thin-gauge thermoforming machines are designed to process plastic sheets with a thickness typically less than 1.5 millimeters (or 0.060 inches). The process involves heating the thin plastic sheet until pliable, forming it over a mold using vacuum or pressure, and cooling it to create the final shape.
