What Is the Thermoforming Process for Shaping Plastics?

TL;DR

Thermoforming is a process for shaping plastics that involves applying heat and pressure to deform a sheet and then cooling it to solidify in the desired shape. Key methods include vacuum forming, pressure forming, and mechanical forming. While thermoforming requires less stress and allows for final product shaping, it is not suitable for thermosetting plastics and necessitates precise trimming.
