  • Thermoforming
    Thermoforming is a term used to describe two processes for making products from plastic sheets. In a vacuum-forming process, hot thermoplastic sheets are laid over a mold. A vacuum removes air, drawing the plastic into the cavities of the mold. When the plastic cools, the molded product is removed

    design can be a major problem, because one of the hallmarks of the thermoforming process is its inconsistency. If 10 shots are formed, all 10 will be measurably different; the key is keeping the differences to a minimum. In the basic process, called vacuum forming, plastic sheet is heated past its

    , the faulty cycles are automatically expelled. If the error occurs in a series, the machine will stop, which means no faulty packages will be delivered. With a thermoforming machine, the temperature in the forming station is monitored. In addition, the leak tightness of the formed packaging moulds

    and a telephone line, diagnostic technicians from the equipment manufacturer can help determine problems and reprogram machinery. Effective medical thermoforming also requires close monitoring of the systems providing compressed air, vacuum, electricity, and water. It is important that thermoforming

    process may occur inside the forming die or immediately preceding it. Also in the forming area, vacuum or compressed air pulls or presses the film onto the die. There are three basic types of thermoforming technology: negative, negative plug-assist, and positive. Inside the forming die, heated film can
