Vender 1 Set Extrusion Head Nozzle Heating Kit Extruder Kit for 3D Printer al mejor precio

Description: Alloy Nozzle: High quality alloy nozzle, makes the discharge more smoothly. Electroplating heating blocks with strong corrosion resistance, high temperature resistance, thermal conductivity. Reliable External Structure: Heat shield has been isolated from the hot side structure parts. Does not bearing, so that the heat insulation layer, and the wall is thin. Heat Dissipation: Bilateral multiple heat dissipation holes can better output heat, reliable and solid external structure. Work Temperatures Scope: Heating block through a specially designed high temperature copper alloy under the high temperature of 550 Celsius above will not soften, threads will not deformation at high temperature. Heating blocks on the nickel coating is reduced. The wear and tear of radiation loss and prevent the thread. Specification: Material: Copper Alloy Size: Approx. 19x70.5mm/0.75x2.78inch Package Includes: 1 Set 3D Printer Extrusion Heating Kit Note: 1. Please allow 1-3mm error due to manual measurement. 2. Wish you a wonderful on-line shopping!
