The manufacturing process of pressure-forming is an advanced form of vacuum forming. A composite is heated and material placed into the mold, then heat and pressure are applied to shape the material to the mold. Pressure-forming manufacturing uses air pressure to increase the details of the mold to include intricate features in the product that cannot be achieved with vacuum forming alone. The final product resembles the look and feel of an injection or structural foam-molded part at a cost closer to a vacuum-formed product.
In terms of carriers and cases, the final product follows the contours of the housing and fits the shape as a close representation of the thing in which it holds. Pressure-forming manufacturing is best used when precise details or an attractive overall appearance in the final product is required, as it offers high detailing at a lower cost than injection molding.
