How does the Thermoforming process work?
The thermoforming process works by heating a plastic sheet until it becomes pliable. This heated sheet is then formed over a mold using vacuum or pressure. Once the plastic cools, it retains the shape of the mold. The process typically involves several steps: heating, forming, cooling, and trimming.
During heating, the sheet is uniformly warmed to a specific temperature. The forming stage uses either vacuum or pressure to shape the plastic. In vacuum forming, air is removed from beneath the sheet, allowing it to conform to the mold. Pressure forming uses air pressure to push the sheet against the mold.
After forming, the plastic is cooled to solidify its shape. Finally, trimming removes any excess material from the edges. This process is efficient for producing large quantities of consistent parts. It is widely used in packaging, automotive, and consumer products.
What are the key stages in the Thermoforming process?
The key stages in the thermoforming process include heating, forming, cooling, and trimming. In the heating stage, plastic sheets are heated to a pliable temperature.
