Abstract
A method for the fabrication of a filter in a frame where a pre-formed pleated filter matrix is inserted into an injection mold tool. Then a suitable elastic thermoplastic material is injected into the tool. The amount of elastic thermoplastic material injected is less than the available space between the filter matrix and the tool so that the pressure will rapidly drop as the material flows from the point of injection.
