Rubber Molding Considerations

The manufacturing of rubber parts is accomplished in one of three ways: transfer molding, compression molding or injection molding. (Each is described later in more detail.) The choice of process depends on a number of factors, including the size, shape and function of the part, anticipated quantity, type and cost of the raw material. The three methods, however, share certain basic characteristics that are important to understand when designing custom molded rubber parts.
