The machine adopts piston or plunger quantitative system, with filling accuracy up to ±0.2%. It is equipped with electronic weighing or servo drive technology, and has anti-drip and anti-drawing design; the filling head has a built-in one-way valve, which closes quickly after filling to avoid material residue, optimizes the shape of the outlet and the surface treatment process, and effectively solves the problem of high-viscosity paste drawing. Equipped with photoelectric sensors, it can realize functions such as no bottle, no filling, and automatic positioning of containers.
