A compression molding, extrusion, injection molding, blow molding, and low foaming modular plastic mold, which includes a variable combination of the die cavity by the board, die and die assembly consisting of a combination of card board The die, punch combination from the substrate, the punch assembly, punch combo card board, cut side cavity truncated components and combination plates with variable core punch. Convex mold, coordinated and assisted molding die change systems. Processability of different shapes, different sizes of plastic parts series. Plastics processing industry and plastic molding machine supporting, giving plastics to complete configuration and precise dimensions of the tool. Because many plastic varieties and processing methods, structural plastic molding machines and plastic products also of sophistication varies, therefore, the type and structure of the plastic mold is varied.
