Advanced Micro Mold Cavity Manufacturing Technique

Production of precision micro parts has always been a challenge to industry. Latest developments in micro molding technology have made the process a reliable and cost effective production method. However, successful application of micro injection molding is frequently determined by how good and accurate we are in the design and manufacture of micro mold cavity. Conventional machining methods are far from satisfactory. Non-conventional methods like photolithography or electrochemical machining have been developed primarily for certain specific kinds of microstructures. Since the geometry of micro mold cavity differs from one micro part to another, we have successfully developed a manufacturing technique that combines micromachining and advanced micro-electroforming together to embrace a wider range of feature size, aspect ratio or surface finish. Precision micro parts once made by expensive processes can now be produced by micro injection molding at a much lower cost.
