Injection Molding The gate and runner system that you use to move plastic into an injection molding cavity are critical design parameters. Suppose the polymer material that you are using has a viscosity μ of 950Ns/m² under your processing conditions. Suppose your initial gate and round runner system is 3.5 mm in diameter and approximately 25 mm long. Your part has a volume of approximately 20000 mm³ and a projected area of approximately 1800 mm². Your Engel machine claims that it can melt and deliver material at a rate of 165 cm³/sec. Assume that there is no pressure loss between the mold cavity and the runner system, and none of the clamping force is lost in deforming the molds when they come together.
