ABSTRACT:
A system and method including an injection molding system (e.g., nozzle) having a nozzle body with a heater holding portion that receives a heating device that is releasably secured in the heater holding portion. The nozzle has at least one flat or planar outer surface and can be made from a high wear and high pressure resistant material (e.g., Aermet). A slot of the heater holding portion and the heating device can be of complimentary geometries, such as rectangular shaped, wedge shaped, or any other shape. The heating device can include a holding device having receiving areas. Each receiving area can receive a respective heater that can be removed from the nozzle body. The nozzle body is provided with a clamping mechanism to insure an intimate contact between the heater holding portion and the heater device.
