The Making of Injection Molding Machines for Shoe Insoles from Silicone Rubber Composite Materials

The injection molding machine is one of the most significant and rational forming methods available for processing plastic materials. An injection molding machine has three basic components. Injection unit, mold, and clamping system. The injected unit, also called a plasticator, prepares a precise melt of the plastic and through the injected unit transfers the melt to the next component which is the mold. The clamping system closes and opens the mold. Injection molding machines are commonly used for the manufacture of plastic-based products, but in this study, the basic materials were changed to silicone rubber and talc composites Silicone rubber is used as matrix and talc as filler. Due to the different mechanical properties that exist between plastic and silicone rubber, some parts of the injection molding machine need to be changed and the parameters that affect this tool must be considered. Parameters that need to be considered are the dimensions of each part of the tool, temperature, pressure, and time.
