Thermoforming is the process of converting a thermoplastic sheet into a three-dimensional shape.

Within the medical market, thermoforming is used to make packaging for medical devices.

Basic Steps of Thermoforming

• Plastic sheet is heated in an oven.
• Hot sheet is then transported to a molding area and draped over a cool mold.
• Vacuum is drawn through the mold, pulling the hot sheet onto the mold.
• Hot sheet takes the shape of the mold.
• Plastic cools and is transported to a trimming station where the formed part is trimmed out of the full width sheet.
