The main factors affecting the viscosity of solvent-based gravure printing ink are the following.

(1) Fix the viscosity of the resin solution. The resin viscosity is large, the ink viscosity is high, and vice versa.

(2) The matching of pigment and resin liquid. If a coagulative reaction occurs between the two, the viscosity of the ink system is high, otherwise it is low.

(3) Miscibility and compatibility of solvent and dispersion. If the solvent can dilute the dispersion in any proportion, the viscosity of the ink is low, and vice versa.

(4) Temperature. Low temperature, high ink viscosity, and vice versa.

If the viscosity of the solvent-based gravure printing ink is too low, it may cause pinholes in the printed product, or the large-area color block is not flat and smooth, and it may make the printed product false and appear halo. When printing a substrate with a smooth surface, the adhesion of the ink is low; when printing paper, it will appear powdering and dusting.

If the viscosity of the solvent-based gravure printing ink is too high, it will cause printing defects such as scratches, bite, paste, and "orange peel".

Filling And Linking Technology

Helper has designed different filler series for small scale producer, medium sized business, and industrial enterprises,such as vacuum filler,piston stuffers.

---The vane cell feed system, together with vacuum pumping system, guarantees a long service life and the highest product quality.

---Mechanical filler is newly designed by our feeding technical team and it represents a new beginning of Chinese mechanical filling machine.

---Pneumatic filler is the most economical solution for the beginning of small scale producer with frequent changes in the product range.

sausage linking system,sausage hanging system:

The sausage linking and hanging system is the advanced solution to hang the sausages immediately after twisting-off. The workers handle easily the hanged sausages to smoking step by using a hanging stick. A simple twist linking device is also available to the filling machine to realize automatic twisting products production.
