ABSTRACT:
A method of injection molding and a mold for the forming of a thin walled fabric reinforced elastomeric diaphragm. According to the method, a thin, precut, preformed sheet of fabric material is placed within a suitable injection mold cavity. Subsequently, a high molecular weight elastomer is injected into the mold cavity in a controlled manner to prevent migration or weave distortion of the fabric material.
