Abstract
Disclosed is a side-gate nozzle having a nozzle body, a nozzle tip and a transfer member. The nozzle body includes a heater, a longitudinally extending nozzle channel, and a bore extending from an exterior side wall of the nozzle body to the nozzle channel. The nozzle tip includes a tip member, a tip channel extending therethrough and a sealing member surrounding the tip member and in which the tip member is received. The transfer member seats against a step in the bore in the nozzle body and includes a bearing surface against which the nozzle tip is slidably seated and a transfer channel extending therethrough in fluid communication between the nozzle channel and the tip channel. In operation thermal expansion of the transfer member along its length applies a sealing force against the nozzle tip.
