What is a Chiller in Blow Molding Machine Auxiliary Systems?

A chiller is an industrial cooling device used to remove heat from the blow molding process. During blow molding, PET or other plastics are heated to a precise temperature before being shaped into bottles. Auxiliary chillers regulate mold temperature, preventing overheating and ensuring uniform bottle quality.

Key Functions:

• Maintain consistent mold and machine temperature.

• Remove heat generated by the blow molding process.

• Improve cycle times and production efficiency.

• Protect molds and auxiliary equipment from thermal damage.

Working Principle of Chillers in Blow Molding Systems

1. Heat Absorption: Water or a cooling fluid absorbs heat from molds and machine components.

2. Cooling Circulation: A pump circulates the chilled fluid through pipes to blow molding molds.

3. Heat Transfer: The heated fluid passes through the chiller’s heat exchanger.

4. Temperature Control: Thermostats and sensors maintain the fluid at a precise temperature.

5. Return Flow: The cooled fluid is recirculated to the blow molding machine for continuous cooling.
