NettetSome sections of larger parts are being successfully molded with wall thicknesses of less than .01 inch. Each individual plastic material has its own wall thickness limitations for good quality, efficient injection molding. For conventional injection molding, a practical minimum wall thickness is in the range of .03 to .04 inch. NettetWing gates must be used for thick-walled plastic injection moulded items. In this approach, a wing-shaped structure can be connected to a plastic injection moulding component that is not suited for establishing the gate squarely on the plastic part and is sufficient to produce remnant distortion at the gate after moulding, and then the gate …
