Thermoforming
Thermoforming is a process that combines plastic, heat and molding. Using an oven, a plastic sheet is heated to be softened, in this state it is then possible to shape it by placing it on a mold. The plastic is then cooled and thus keeps the desired shape.
Vacuum Forming
This process produces parts by shaping preheated plastic sheets using a mold made of wood, resin, or aluminum. The air between the sheets and the mold is evacuated, making the plastic adhere to the mold. Once cooled, it is then removed from it before being cut out and trimmed during a secondary operation.
Pressure Forming
If you thought it impossible to pull off high definition or greater complexity through thermoforming, you could be in for a surprise. By combining air pressure and vacuum suction, pressure forming can produce a look extremely similar to that of injection molded parts. Well-defined logos, small radiuses, reverse angles, and high tolerance levels can all be achieved with this method. If you cannot afford to invest large sums in injection tooling but still want similar results, this solution is for you!
Twin Sheet Forming
This process is ideal for more complex products that require increased rigidity or hollow space. Using two molds facing one another, it can press together two parts into a single one during the molding process. Not only can two different materials be used with this method, but reinforcements or attachments can also be added. This method is fast and can feature a wider range of materials than rotomolding, and it rivals blow molding in every aspect.
