Place the printed film into the molding tool
Printed film heated by infrared heater (temperature adjustable)
The printed film is clamped inside the molding tool and formed in its softening temperature region by suddenly applying compressed air that is heated under high pressure.
By thermoforming, radiant heaters are used to heat the film to a level much higher than its softening temperature.
The film is then drawn into a heated mold by vacuum and/or compressed air and formed. In addition, the film can be contoured mechanically using punches or other expertise.
Instead of pumping the air between the plastic and the mold through a vacuum, pressure molding uses high air pressure to push the plastic down into the bottom of the mold. In pressure molding, the machine used to hold the plastic mold in place will ensure that the material is heated to the correct temperature for proper flexibility.
Pressure molding, which is commonly used in medical devices due to its ability to provide complex shapes with high-precision edges and more ideal surfaces. Office equipment, such as telephones, can also take advantage of the technological advances offered by pressure-molded plastics. It is also used in the main control panel and detailed components for small manufacturing jobs.
The printed film is sandwiched inside the forming tool and formed within its softening temperature range by suddenly applying high pressure to heat the compressed air. For thermoforming, a radiant heater is used to heat the film to a temperature well above its softening temperature.
Instead of pumping the air between the plastic and the mold through a vacuum, pressure molding uses high pressure to push the plastic down into the lower abdomen of the mold. In pressure molding, the machine used to hold the plastic mold in place will ensure that the material is heated to the correct temperature for proper flexibility.
