The interface is closely fitted and the contact surface is smooth, which can solve the problem of material leakage and effectively prevent the printing head from material leakage.
Mature processing technology, solve the problem of rough and uneven inner wall surface.
Smooth inner wall, no burr, small viscosity coefficient.
The shape is smooth and shiny, no burr, clear lettering, high recognition, and quality in detail.
Cutting chamfering, chamfering cutting round, reduce the resistance of edges and corners to consumables, avoid blocking.
