The process of injection molding rubber compounds runs most efficiently when operated continuously. Setup costs for injection molding are usually higher than for other molding processes, but operating costs can be significantly lower if the process operates continuously (ref. 1). Economic benefits from injection molding depend on successful processing of each batch to maintain continuous operation. Rubber testing helps optimize molding conditions, predicts the processing potential of each batch and predicts or measures the quality of cured products.
The injection molding process consists of an injection machine, mold and a rubber compound. Each component ...
