Formolene PolypropyleneInjection Molding Process GuidelinesPolypropyleneInjection Molding Process GuidelinesThe following is given as a potential process starting point. The final molding process may be dependent upon factorslike: part and tooling design, wall thickness, flow lengths, gate size, number of cavities, cycle time and desired level ofmolded part quality, for Temperature: 400 470 F (200 250 C)Set barrel temperatures, screw speed (60 to 125 rpm) and back pressure (50 to 200 psi) so that the melt temperaturecoming out of press nozzle is in the above range, , temperature of an airshot using a needle Temperature:Rear.
