TopChiller: Your Professional Plastic Chiller Supplier

As a professional plastic chiller supplier with 20 years experience, TopChiller offers packaged and portable water-cooled chillers, with capacities from 2ton to 200 tons.

In plastic chillers, the Water-cooled chiller is a more cooling effect than the air-cooled chiller.

AC-Series air-cooled chillers equipped with integral pumps and tanks. But a closed-loop system like a plate heat exchanger or shell and tube are available.

Our AW-Series water-cooled chillers are used when a condenser water loop (city water or open loop cooling tower) is available.

Here are some tips to determine the size of a correct plastic chiller for your plastic process cooling application:

  1. Calculate the pounds of material per hour being processed. That is the plastic material.
  2. Determine how many kilograms per hour are required for each ton of cooling capacity.
  3. Double-check if there is an external water storage tank for the chiller to determine closed-loop or open-loop for a plastic chiller. Like there is a water tank for regular extrusion or plastic extruder.
  4. Size the equipment cooling capacity like the clamping force of the injection molding machine.
  5. Confirm the water pressure and water flow rate required for a plastic chiller.
  6. Combine the process and equipment cooling requirements, like for injection molding machine, the plastic chiller needs to cool down the plastic mold only or together with the plastic machine.

As a professional plastic chiller manufacturer, TopChiller is willing to provide all technical support for end-users.

Plastic Chiller- The Complete Buying Guide for Importers

What is a plastic chiller?

As we know, plastic chillers of both water chillers and air chillers are one of the auxiliary machinery including plastic crusher, mold temperature controller, mold dehumidification, autoloader, conveying system, mixer, and dryer.

We can divide plastic machinery into injection molding, blow molding and extrusion/extruder segments of the whole plastic industry.

Plastic chiller is a kind of refrigeration system applies to mold cooling of plastic processing machine that greatly improves the cosmetic finish of the plastic product.

The plastic chiller can also reduce grain mark and internal stress of plastic product to make sure the plastic product does not shrink and deform, which help the mold release of plastic product and accelerates its molding so that remarkably improve the production efficiency of the plastic molding machine.

Precision temperature control is very important for plastic process heating and transfer systems. A cooling system used for a plastic processing machine, we call it is a plastic chiller.

Let’s have a detailed look at the below explanation regarding the plastic chiller.

Process cooling in plastic processing is necessary as considerable amounts of heat have to be removed from the material, mold, or machines, such as plastic injection molding machine and etc..,

Before shaping, thermoplastic materials such as polypropylene, nylon, and PET, the, etc thermoplastic must be heated to their molten temperature.

When molten, they can then be manipulated (injection-molded, etc) to a new shape. Finally, they must be solidified via cooling.

Why plastic machines need plastic chillers?

So now we can know plastic chiller is necessary for your plastic machines or plastic processing.

Let’s know why your plastic machines need plastic chillers?

Plastic chillers are always used to cooling the hot plastic that is injected from injection molding to maximize productivity and improve quality.

By cooling down the plastic process equipment that is used to produce plastic products, such as hydraulics of the molding machine, gearbox, and barrel of the injection molding machine, to save energy and extend the lifetime of the machine.


One of the most important steps in the mold-making process is a consistent and proper cooling cycle.

This is due to the fact cooling rates can have a significant influence on the overall quality of the finished item.

The cooling cycle must remain consistent throughout the entire production run to ensure all items are equal in quality.

Plastic chiller- includes air chiller and water chiller will provide this consistent cooling water during the process.

This is the most advantage and purpose of using a plastic chiller

How does the plastic chiller work with the plastic machine?

Plastic chillers are used in a variety of applications where chilled water or liquid are circulated through process plastic equipment.

Commonly used to cool plastic products and plastic machinery, water chillers are used in a multitude of different applications including injection molding machines, blowing molding machines, and extrusion lines.

The function of a plastic chiller is to move heat from one location (usually process in injection molding or product) to another place (usually the air outside the manufacturing facility).

It is very common to use a water solution to transfer the heat to and from the plastic chiller which may require the process chiller to have a reservoir and pumping system.

Regardless of your plastic industry and molding process, making sure that you have sufficient water cooling is critical to productivity and cost savings also in the injection molding machine.

water chiller for plastic machine

How to size a proper plastic chiller for your plastic machine?

Plastic chillers are playing a significant part in plastic processing, but how to size a  correct plastic chiller size or plastic chiller model for your plastic plant?

Please follow the below steps, maybe you will get a bright idea of this problem.

A. We know for plastic chiller, there are air cooled chiller and water cooled chiller for optional.  The most important thing: you must confirm air-cooled chiller or water cooled chiller you prefer?

This is simple to clarify: do you have or need a cooling tower? If yes, it should be water cooled chiller. If no, you have no or don’t need any cooling tower, you must go for an air-cooled chiller.

Compared with air-cooled chiller, the water-cooled chiller is more efficient in cooling, but air-cooled chiller is more convenient to install and maintain.

B. You can ask your plastic machine supplier about the required plastic chiller cooling capacity.

If there is no positive reply, it no matters.

Just confirm the plastic mold inlet and outlet water temperature, the required cooling water flow rate, then we can compute the right plastic chiller cooling capacity.

Please follow the below formula we are using:

Plastic chiller cooling capacity(KW)

= Water flow rate(Liter/Second)*Delta T(Inlet-outlet)*4.187(water specific heat)

Now we can cite an example, one client does not have a cooling tower, needs a plastic chiller with an inlet water temperature 30℃, outlet water temperature 25℃, with a cooling water flow rate is 4Liters/Second.

We can get the right plastic chiller cooling capacity =4L/S *(30℃-25℃)*4.187=83.74KW

On the customer site, an air-cooled chiller with 83.74kw cooling capacity is the best chiller size.

C. With rich experience for plastic chiller matching for your plastic machines, TopChiller has a conclusion of chiller sizing, especially for plastic injection molding machines.

If you don’t know the chiller cooling capacity, please confirm the clamping force of your injection molding machine.

As the clamping force is 280Ton, each 80Ton capacity force will match 2.5KW air-cooled chiller. so for a 250ton injection molding machine, the air-cooled chiller cooling capacity is 8.75KW

You must consider all project site information and your plastic machine to choose the correct plastic chiller solution.

Plastic chillers for plastic machinery applications

As we know, plastic chiller including air-cooled chiller and water cooled chiller, sometimes some clients also prefer to use the cooling tower as their cooling water source.

All depend on their cooling water requirements and project site information.

Plastic machinery can be divided into 6 segments as below:

A. Injection molding machines: Injection molding machine, general purpose/ Injection molding machine,multi-component/Injection molding machine, multi-station/Injection molding machine, for thermosets/Injection molding machine, for rubber

Increasing the amount of injection on an injection molding machine can be a tricky balancing issue. If your mold and cool the mold too quickly, your product quality may not be guaranteed.

If your mold and cools too slowly, you are increasing your cost. The key point is to maximize the amount of injection – careful consideration of the right injection molding process is critical.

Molding cycle
In the injection molding process, the molding process usually has three stages:
1. Injection molding cycle operation injection – when a plastic material is injected into the mold.
2. Mold cooling – when the part material solidifies
3. Open mold and spray – when the solid portion is cooled and ready to be ejected from the mold.
Why is cooling important in the molding cycle?

Consistent cooling water is necessary during the molding cycle because the material from which the part is made must be cured in the mold before being sprayed.

Without proper cooling time during the manufacturing process, there may be a large number of part defects such as warpage and deformation. This is primarily because the thermoplastic or other components of the material must be allowed to cool properly to ensure structural integrity.

In most cases, cooling is the most time-consuming part of the injection molding process, but shortening the time too short can result in a large number of product defects.

In order to maximize production, the best solution is to find an acceptable cooling time section and make sure you have the proper cooling to eliminate the necessary heat.

plastic chiller

The mold accumulates heat during many injections. Working with plastic chiller specialists with experience in injection molding applications, you can prevent this heat build-up and consistently achieve a uniform cooling time.

Ways to reduce injection molding cooling time by using plastic chillers:
There are two heat transfer points in the molding process:
1) between the plastic and the mold;
2) Between the mold and the cooled L water. Properly designing the process at these points minimizes cooling time and provides effective cooling.

Injection molding process timeline
(1) Maximum heat removal (between plastic and mold), it is extremely important to design effective mold channels. To make sure at the point.
(2) For proper cooling of the coolant must be cold enough to prevent heat build-up in the mold and eliminate the heat added during each cycle. At this point, the choice of cooler is critical. An appropriately sized chiller will provide sufficient heat removal to prevent heat build-up in the mold.

The problem that should be paid attention to when choosing an injection molding chiller
To properly apply a mold chiller for injection molding, consider the following:
Constant cycle time is extremely important to maximize system throughput. In order to consistently provide proper cooling, you should have enough data in your process.
Do you have a cooling requirement?
Do you have information about traffic?
Do you have information to cool down? (Δt)
Do you have more injection molding machines?

Load matching or variable drive plastic chillers will allow you to provide adequate cooling for multiple units.

As the heat load increases, the plastic chiller will react accordingly to ensure that the proper coolant temperature is maintained.
