Venting • Place vents at the end of fill and anywhere potential knit/weld lines will occur. • All vents need to be vented to atmosphere. • For circular parts, full perimeter venting is recommended. • Cut vent depths to 0.0007″–0.0015″. Incomplete Fill Melt and/or mold temperature too cold • Increase nozzle and barrel temperatures • Check thermocouples and heater bands Shot size • Increase shot size • Adjust transfer position to 98% full • Increase cushion • Enlarge or widen vents and increase number of vents • Check that vents are unplugged • Check that gates are unplugged • Enlarge gates and/or runners • Perform short shots to determine fill pattern and verify proper vent location • Increase wall thickness to move gas trap to parting line Brittleness Degraded/overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel Gate location and/or size • Relocate gate to non-stress area • Increase gate size to allow higher flow rate and lower molded-in stress Wet material • Check moisture.

Its customer, a luxury European automaker, was buying radiator shrouds that the molder made from a black talc-filled polypropylene on a single-cavity injection system. Spikes in production were great for the molder’s bottom line, but sometimes the increased demand outstripped its ability to fill orders. The additive concentrate not only reduced cycle times as expected, it allowed the supplier to achieve better flow and mold filling.
