thermoformingproces
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, stretched onto or into a mold, and cooled to form a finished product. The process begins with a plastic sheet, which can be extruded from various polymers like PET, PVC, polystyrene, or ABS. This sheet is then heated evenly on both sides using radiant heaters until it reaches its softening point. Once the material is sufficiently pliable, it is brought into contact with a mold. A vacuum is typically applied to draw the plastic sheet tightly against the mold's surface, ensuring intricate details are captured. Alternatively, a plug assist or compressed air can be used to help push the plastic into the mold cavity. After the plastic has conformed to the mold's shape, it is cooled, solidifying it into the desired form. Finally, excess material, known as trim, is removed from the formed part, completing the thermoforming process. This method is widely used for producing packaging, automotive components, appliance housings, and consumer goods due to its efficiency and ability to create complex shapes.
