Heating block & throat Material upgrade: Upgrading the heating block with chrome zirconium copper nickel platingtreatment for fast thermal conductivity and high temperature resistance for printing, The titanium alloy throat is wrapped with chromium zirconium copper for better heat dissipation. The throat and heating block are integrated into a formed structure: The throat structure has been upgraded, and a step limit has been added at the joint with the heating block, Solve the phenomenon of material leakage and detachment. Heating block, nozzle High temperature and wear resistance upgrade: The heating block has been upgraded to chrome zirconium plated copper and nickel plated treatment, which can withstand high temperatureprinting at 550 ° C and has fast thermal conductivity. The nozzle is made of hardened steel SKD11, which has undergone quenching hardening treatment and surface DLC nano treatment. It can be heated up to 550 ° C or above, making it more wear-resistant and extending its service life. Upgrade of nozzle structure: The heating block and nozzle are connected by threads, utilizing the contact between the nozzle and the step at the bottom of the throat to firmly solve the problem of detachment and reduce the possibility of material leakage. The detachable nozzle reduces the cost of use. Inner wall of throat and nozzle Roughness Ra 0.4:The inner walls of the throat and nozzle are smooth, reducing blockage and improving printing quality.
