injection speed     fast
injection speed, injection pressure and holding pressure have to be optimized to the inpidual article geometry. to avoid material degradation during processing low back pressure and minimum screw speed have to be used. overheating of the material has to be avoided, in particular for flame retardant grades. up to 25% clean and dry regrind may be used.
