The utility model provides an aluminum alloy heater. In order to solve the problem of yellowing of existing products, the following technical scheme is adopted: the heater includes a heating wire, an aluminum alloy, an aluminum alloy heater and a hot nozzle body. The aluminum alloy heater is a cylinder with an opening on one side, the aluminum alloy heater includes a heating wire and an aluminum alloy, the heating wire is reasonably arranged inside the aluminum alloy, and the hot nozzle body is installed in the aluminum alloy. The inner side of the alloy heater. The utility model arranges the straight heating wires reasonably, and then uses aluminum alloy to cast into the heater, which avoids the problem of uneven heating, improves the stability of the hot runner system and reduces the whiteness produced by the injection molding factory. And the defect rate of light-colored injection products due to chromatic aberration problems.
