Low Pressure Insert Molding Processes - Options for Automotive Application

Low-pressure molding processes have been presented for numerous applications on automobiles. While some suppliers of these technologies provide entire systems, some potential applications only require moderate alteration of current injection molding equipment. This area of technology includes low-pressure insert molding, injection compression molding, compression molding, and extrusion-compression molding. As a reduced pressure molding process, gas-assisted injection molding can even be applied as a low-pressure technique. The processes can be described using the sequence of operation for each. Overall, there are advantages and limitations for each process and cost considerations that may limit successful application.
