How Does Thermoforming Work?
Thermoforming is a versatile and widely used manufacturing process for creating three-dimensional plastic shapes. It's responsible for a surprising number of everyday items, from packaging to vehicle parts. But how exactly does it work? Let's delve into the steps that transform flat plastic sheets into useful objects. Thick Gauge Thermoforming Machines The Power of Heat and Pressure At the heart of thermoforming lies the unique property of thermoplastics. Unlike other plastics, these materials soften and become moldable when heated. The process typically involves these key stages: 1. Sheet Heating: A large sheet of thermoplastic material is fed into the machine. Using radiant heat panels or ovens, the sheet is heated uniformly to a precise temperature. This temperature is crucial, ensuring the plastic becomes pliable enough for forming without melting. 2. Mold Positioning: A single-sided or double-sided mold, depending on the desired shape complexity...
