Simulate the blow molding process of hollow containers and predict the wall thickness of the molded products.
BlowView is a blow molding simulation software developed as part of a consortium research program that started in 1992 at the National Research Council (NRC) Industrial Materials Institute in Canada. It prevents the occurrence of molding defects in the blow molding process, shortening trial runs before mass production, thereby reducing development costs and shortening lead times. The BlowView simulation allows for the evaluation of parameters such as the thickness distribution of molded products and the cooling and shrinkage after molding, enabling the identification of desirable mold shapes and molding conditions. It features the optimization of parison extrusion conditions to minimize the weight and thickness variation of molded products, and the obtained data can be used as control conditions for the molding machine.

basic information
In the extrusion blow molding process simulation, the calculations include parison extrusion → mold clamping → blowing → cooling inside the mold → cooling outside the mold, and predictions of the thickness of the molded product are made. The die shape, flow rate, and time profiles of die opening amount/rate are set, and their effects on the thickness of the molded product are evaluated. Control conditions such as parison extrusion flow rate, temperature, mandrel opening, and die gap can be specified as design variables, allowing for optimization analysis with the weight of the molded product or thickness deviation as the objective function. The simulation considers swell effects, drawdown effects, parison elongation and deformation, contact with the mold, heat conduction, and friction. It also supports multi-layer molding. In the stretch blow molding process simulation, calculations include preform reheating → rod stretching → blowing → cooling inside the mold → cooling outside the mold. In the preform reheating process, ramp arrangements and reflectors are placed, and the temperature rise of the preform moving within the heating furnace is calculated. An uneven initial temperature distribution can be applied to the preform. In the preform stretching process, parameters such as rod stretching speed, blowing pressure, temperature, and cooling time are set, and the effects of these parameters on the thickness distribution of the molded product are calculated.
