Auto Cooling System
Cooling is one of the largest contributors to the injection molding cycle. After filling and holding, heat must leave the molded part and mold at a controlled rate.
Insufficient water flow, unstable supply temperature, uneven mold circuits, or inadequate cooling capacity can extend cycle time, increase warpage, shift dimensions, and create inconsistent surface quality. A complete auto cooling system coordinates water temperature, flow, pressure, and heat rejection around the actual production process.
Features
- 1. It uses imported high-quality compressors and imported water pumps, which are safe, quiet, power-saving and durable.
- 2. Both water chillers and air chillers use full computer temperature controllers, which are simple to operate and can accurately control the water temperature at 5-35℃.
- 3. Both use current overload protection, high and low voltage control and electronic time delay safety devices, which will promptly issue an alarm and display the cause of the fault when a fault occurs.
- 4. The temperature of the ultra-low temperature chiller can reach below -10℃.
- 5. This series of chillers can be customized to be acid-resistant and alkali-resistant.

How the Industrial Cooling System Works
-
Absorb Heat from the Process
Chilled water flows through the mold, hydraulic circuit or connected production equipment and absorbs process heat.
-
Transfer Heat to the Refrigeration Circuit
The evaporator transfers heat from the process-water circuit into the refrigerant.
-
Move Heat Through the Compressor
The compressor drives refrigerant circulation and raises the pressure required for effective heat rejection.
-
Reject Heat from the System
An air-cooled condenser releases heat into the surrounding air, while a water-cooled condenser transfers heat into an external cooling-water circuit.
-
Return Controlled Chilled Water
The pump delivers controlled chilled water back to the mold or production equipment, completing the cooling loop.
-
Monitor Temperature and System Protection
Controllers monitor water temperature, compressor status and alarms to maintain stable operation and protect system components.
Components of a Complete Injection Molding Cooling System
Chiller Machine
Generates chilled water and removes the calculated heat load from the process-water circuit.
Circulation Pump
Provides the flow and pressure needed to move chilled water through piping, manifolds, molds and connected equipment.
Water Tank or Buffer Tank
Stabilizes water volume, reduces rapid temperature fluctuations and limits unnecessary compressor cycling.
Supply and Return Piping
Carries chilled water between the cooling source and production equipment. Pipe diameter, distance and resistance directly affect system flow.
Mold-Water Distribution
Manifolds and individual cooling circuits distribute water to different mold zones and production machines.
Cooling Tower
Water-cooled chillers require an external condenser-water circuit and cooling tower to release heat from the system.
Intelligent Control
Temperature monitoring, alarms, scheduling and optional MODBUS communication support system visibility and factory integration.
Control Temperature, Flow and Pressure Together
Supply-Water Temperature
The supply temperature determines the cooling condition entering the mold or equipment.
Return-Water Temperature
Return temperature reflects how much heat the chilled water absorbs from the process.
Temperature Difference
The difference between supply and return water helps engineers evaluate system heat removal and operating load.
Water Flow
Insufficient flow reduces heat transfer even when the chiller displays the correct water temperature.
Pump Pressure
Pressure must overcome pipe resistance, elevation, valves, manifolds and mold-channel restrictions.
Simultaneous Heat Load
Centralized systems must be sized from the machines operating at the same time—not simply from total installed machine quantity.
