Pad Printing Machine Automatic Solvent Adding System

How to Maintain Print Quality During Long Printing Runs?

In fact, the evaporation of ink inside the ink cup is mainly caused by agitation due to the reciprocating motion (molecular collision), while the influence of time alone is relatively minor. By using the number of ink cup movements as the basis for solvent addition, this represents a modern and advanced pad printing technology!"

✅ Automatic Solvent Adding Mechanism ｜ ✅ Taiwan Invention Patent: Patent No. I889206 ｜ ✅ Available for New Machines or Retrofit of Existing Machines

Why use an automatic solvent adding mechanism? 

• During the pad printing process, the ink gradually thickens due to solvent evaporation over time, causing color deviations, poor printing quality, and increased cleaning frequency.

• In the pad printing process, ink cup’s movement and sloshing make the ink evaporate and thicken, resulting in smaller image sizes, poor printing performance, and more frequent issues such as ink stringing and breakage.

• Manual solvent addition requires stopping the machine, which is time-consuming and inaccurate, ultimately affecting product quality and production efficiency in the long run!

  

【FineCause New Invention】Smart Solvent Adding System

Our newly developed automatic solvent adding mechanism is installed above the ink cup and allows precise control of the timing and amount of solvent added through the HMI. This system keeps the ink at optimal viscosity during production without the need to stop the machine!

Features:

• Adds solvent in small amounts multiple times to maintain stable ink viscosity for up to 24 hours.

• Automatically adds solvent based on the number of prints to prevent thickened or dried ink.

• No need to stop the machine for automatic solvent addition.

• Does not affect production line continuity, boosting uptime and yield rate.

• Compatible with a variety of inks and materials

• Droplet frequency and volume can be fine-tuned as needed—high flexibility.

Works with both new and existing machines

Older models can be retrofitted to extend machine life and enhance functionality.
