WebbThermoforming is a plastic manufacturing process that involves heating a plastic sheet and forming it using a mold to specific shapes. The shaped plastic then gets cooled down and trimmed to result in the finished part. The process is executed using a thermoforming machine to heat and stretch the pliable thermoplastic sheet over the mold.
