Abstract
A method of adjusting gap of a plastic flow channel is provided in a plastic forming device having a first body part adjacent one side of and adjustable relative to the channel and a second body part on which the first body part is mounted by a tight fitting between the first and second body parts. When the device is not in operation one of the body parts is subjected to a first temperature change producing a temporary temperature differential and a loosening of the fitting between the body parts. Positioning of the first body part on the second body part is adjusted while the fitting is loosened and then the one body part is subjected to a second temperature change opposite to the first temperature change to offset the temperature differential and restore the tight fitting between the body parts.
