Injection Molding Chiller for Mold Cooling and Plastic Processing
APT injection molding chillers provide closed-loop chilled water cooling for plastic injection molds, hydraulic oil cooling, feed throat cooling, process water loops, and centralized injection molding cooling systems. Each chiller can be configured according to injection molding machine tonnage, mold heat load, plastic material, shot weight, cycle time, target mold temperature, flow rate, pump pressure, water quality, voltage, and factory installation conditions.
What Matters Most in Injection Molding Cooling?
An injection molding chiller should be selected around machine tonnage, mold heat load, plastic material, shot weight, cycle time, target mold temperature, cooling water flow rate, pump pressure, number of machines, water quality, ambient temperature, and whether the system is standalone or centralized. Stable chilled-water cooling helps reduce temperature fluctuation and support repeatable molding cycles.
The correct injection molding cooling system is not selected by horsepower alone. APT reviews mold cooling channels, hydraulic oil cooling demand, process water loop, pipe length, filter pressure loss, factory layout, voltage, and whether an air-cooled, water-cooled, or custom centralized system is more suitable.

Injection Molding Chiller FAQ
These questions help engineers and buyers prepare injection molding cooling data before requesting a formal quotation.
What is an injection molding chiller?
An injection molding chiller is an industrial process cooling system that supplies chilled water to injection molds, hydraulic oil cooling circuits, feed throat sections, or process water loops to remove heat and support stable plastic molding production.
Why does injection molding need a chiller?
Injection molding may require a chiller when stable mold temperature, shorter cooling time, continuous production, hydraulic oil temperature control, or centralized process cooling is needed. Stable cooling helps support repeatable cycle time and product consistency.
What size chiller do I need for an injection molding machine?
Chiller size depends on injection machine tonnage, mold heat load, plastic material, shot weight, cycle time, target water temperature, flow rate, pump pressure, number of machines, and working hours.
Should I choose an air-cooled or water-cooled chiller for injection molding?
Air-cooled chillers are suitable for standalone machines and factories without cooling tower water. Water-cooled chillers may be preferred for larger heat loads, centralized cooling, indoor plant rooms, or continuous high-duty production.
Can one chiller cool multiple injection molding machines?
Yes. A centralized injection molding cooling system can serve multiple machines if the total heat load, pump flow, pump pressure, pipe length, water distribution, and control logic are properly designed.
What water temperature is used for injection mold cooling?
Mold cooling water temperature depends on plastic material, mold design, product quality requirements, cycle time, and process conditions. Common chiller outlet temperature may be 5–35°C, but the final setting should follow the molding process requirement.
Can a chiller reduce injection molding cycle time?
A properly selected chiller can improve heat removal from the mold and may help reduce cooling time. Actual cycle improvement depends on mold design, cooling channel layout, water flow, plastic material, and process settings.
What pump flow and pressure are needed?
Pump flow and pressure depend on mold channels, pipe length, filters, machine count, pressure loss, and centralized cooling layout. APT can review flow and pressure requirements before recommending pump configuration.
How does water quality affect injection mold cooling?
Poor water quality can cause scaling, blocked mold channels, reduced heat transfer, unstable cooling, and higher maintenance frequency. Filters, bypass, anti-scaling review, and regular maintenance should be considered.
Can APT customize pump and tank configurations?
Yes. APT can customize pump pressure, water flow, built-in or external tank, buffer tank, filter, bypass, dual pump, stainless steel water circuit, voltage, and control system according to injection molding cooling requirements.
What information should I provide for an injection molding chiller quotation?
Please provide injection machine tonnage, number of machines, plastic material, shot weight, cycle time, target mold temperature, flow rate, pump pressure, cooling water temperature, voltage, ambient temperature, and installation conditions.
Can APT provide centralized injection molding cooling systems?
Yes. APT can provide centralized cooling systems for multiple injection molding machines, including air-cooled or water-cooled chillers, pump and tank modules, piping layout review, PLC control, alarm output, filtration, and custom voltage options.
