Other key processing parameters are slow injection speeds and low back pressures. ** Avoid processing for a resin-rich surface. Draft Angle • Maintain a minimum draft angle of 1/2° per side.

They’ve put a lot of bulky metal, glass, and stone out of work since they came on the scene in a big way back in the 1950s. Other keys to molding electrically conductive compounds are slow injection speeds and low back pressure (e.g., 50 psi).1 Use 50 percent to 75 percent of the injection pressure for the pack and hold pressure.
