Applications of Industrial Chillers in the Printing and Packaging Industry

In the printing and packaging industry, industrial chillers are essential equipment for ensuring precise printing colors and stable packaging formation. They are primarily used in two key processes: cooling ink rollers on printing presses and setting molds on packaging machines. By supplying constant-temperature cooling water, they directly determine product quality and production efficiency. The following information is provided by Jianlong Hydraulic Technology to assist with your procurement decisions:

1. Printing Sector: Stabilizing Colors and Preventing Ink Emulsification

During high-speed printing, ink distribution rollers generate significant heat due to rapid rotation, causing the ink temperature to rise. This alters ink fluidity (making it thinner) and disrupts drying speeds, leading to serious quality issues such as color deviation, registration errors, and even ink emulsification.

1.1 Solution: Chillers circulate constant-temperature cooling water through the interior of cooling rollers (such as ink distribution rollers) to maintain the roller temperature at an optimal level. Specific benefits include:

• Temperature Control Standard: It is generally recommended to keep the cooling water temperature approximately 3°C below room temperature.

• Core Value: Maintains constant ink viscosity to ensure color consistency; prevents ink emulsification caused by overheating, thereby enhancing print clarity.

2. Packaging Sector: Accelerating Setting and Improving Molding Quality

In processes such as blister packaging, bag making, and heat sealing, heated plastic films or containers require rapid cooling to set their shape. Inadequate cooling can lead to defects such as poor blister formation, deformed heat-seal edges, or blurred patterns, directly compromising the packaging's aesthetics and sealing integrity.

2.1 Solution: Chillers connect to packaging molds or cooling rollers, rapidly extracting heat after the material is formed to ensure quick solidification:

• Applicable Equipment: Alu-PVC blister packaging machines, heat-sealing machines, bag-making machines, etc.

• Core Value: Shortens molding cycles and increases production speed; prevents thermal deformation (such as poor blister formation), ensures dimensional accuracy, and reduces material waste. 

2.2 Selection Guide for Packaging Machinery Chillers

The following example represents a mainstream chiller model widely used with packaging machinery and UV printing equipment:

• Cooling Capacity: Approx. 3000W (power output can be selected based on the equipment's heat load)

• Temperature Control Precision: ±0.5°C (for high-precision printing) / ±1°C (for standard packaging)

• Key Features: Dual modes (constant temperature/intelligent control); multiple alarm protections (flow rate, over-temperature, etc.)

• Cooling Type: Primarily air-cooled (easy installation; no cooling tower required)

If the packaging workshop environment has high dust levels or poor water quality, we recommend selecting a model equipped with a stainless steel water tank and filtration system, and cleaning the heat dissipation coils regularly to ensure long-term, stable operation.
