Features: Brand new and high quality The heating block is upgraded to nickel-plated coppers, which is suitable for printing. However, the existing ceramic sheet and heat-sensitive accessories need to be upgraded, and the overall temperature resistance is 300 degrees. The nozzle is made of hardened steel after quenching and hardening treatments, more wear-resistant and prolongs the printing service life. The roughness of the inner wall of the throat and nozzle is Ra0.4, which reduces plugging and improves printing quality; the overall hot section is lengthened, and the extrusion flow rate can reach 33mm³. The radiators and the throat are fixed with screws, and the connection is stable. The throat is fixed with two alloy screws to effectively block heat transfer; the screws are gently locked during installation, and the force should be uniform to avoid deformation and hardening. . The steel nozzle can be disassembled and replaced to reduce the cost of use; the joint can also be disassembled, and can be customized and adapted to other models according to the size.
