Plastics are either organic or semi-organic materials that have (as their main attribute) a very large molecular weight. These very large molecules, or macromolecules, give them their distinct properties and material behavior, when compared to other materials used in manufacturing or found in nature.
Two shot (2K) injection thermoplastic molding dates back several decades, from the multicolor molding of typewriter keys (to produce permanent characters on the keys), to the integration of the multiple parts that make up a car’s headlights. This process has since advanced to allow for the consistent and cost-effective manufacture of multicolor/multifunction thermoplastic/thermoset products for a variety of innovative applications. SIMTEC Silicone Parts prides itself in being at the forefront of two shot LSR/Thermoplastic technology.
