Types of Chillers Used in Plastic Processes
Scroll chillers are the most widely used cooling equipment in plastics processing. They offer a wide cooling capacity, stable operation, and support continuous 24-hour operation.
The compressor refrigeration system of the scroll chiller is optimized for high temperature control accuracy, significantly reducing the cooling time of your plastic products and improving dimensional stability. Meanwhile, they can centrally cool multiple injection molding machines or extrusion lines, reducing your management costs.
However, the scroll chiller will occupy a relatively large area, and the initial investment is higher than that of portable chillers. But in medium to large-sized factories, their long-term operating costs are lower.
Screw chillers utilize screw compressors and are renowned for their high operating efficiency and large cooling capacity. And, it can handle demanding jobs without breaking a sweat. If your factory runs at high capacity and needs to keep going around the clock, screw chillers can keep up.
They maintain high energy efficiency under partial load, being more energy-efficient than reciprocating or scroll chillers. With fewer moving parts and a simpler design, they don’t break down as often, and you won’t need to call maintenance all the time.
However, screw chillers are relatively large, leading to higher purchase costs. If you’re running a smaller operation, a screw chiller might be the suitable chiller type for you.
Air-cooled chillers use fans to dissipate heat generated by the condenser into the air. They’re easy to set up and start working right away. They are commonly used in small to medium-sized production lines such as injection molding, blow molding, and extrusion. Their compact structure allows for direct placement in workshops or outdoors.
Furthermore, they do not require a cooling tower, saving on initial investment and installation time. Since they don’t use much water, they’re perfect for places where water’s hard to come by.
In high-temperature and high-humidity environments, the cooling efficiency of air-cooled chillers will drop. Compared to water-cooled chillers, their operating noise is relatively higher.
Water-cooled chillers remove heat through cooling water, offering high cooling efficiency and are often used in centralized cooling systems in injection molding workshops or large extrusion production lines. They provide stable and reliable performance for continuous operation, especially in high-load industrial environments.
They keep things cool and steady even when the workload’s heavy or the machines run nonstop. Also, they’re quiet. For the same cooling job, water-cooled chillers use less energy than air-cooled ones, which means you save a lot on electricity over time.
The downside is also obvious. They cost more to get going. You’ll need a cooling tower, pumps, and a water treatment system to make it start.
Advantages of Chillers in Plastic Processes
A good chiller isn’t just about cooling things down. It can handle dehumidification, drying, and keep the temperature just where you want it. This multi-tasking saves you both space and money upfront. Plus, built-in safety features—like overload protection, overheat shutoff, and emergency stop switches—keep your operation safe if something goes wrong.
The water tank and structural components of the plastic chiller are made of stainless steel, and all parts in direct contact with water are applied corrosion-resistant coating, which can adapt to the humid and poor water quality environment. It also dramatically reduces the risk of rusting and scaling, ensuring the smooth progress of your process.
Efficient cooling pulls heat out of your molds fast, so your plastic products set and harden quicker. That means shorter molding cycles, more products made per hour, and less downtime. Stable cooling also brings less rework, which boosts your overall output and gives you a real competitive advantage.
With a PLC temperature controller, your chiller keeps everything right in the sweet spot. This tight control improves the look and consistency of your plastics—no more flow marks, shrinkage, or weird textures. Your products hold their shape and size, which keeps your customers happy.
Using a plastic processing chiller can diminish defects caused by temperature fluctuations, such as warping, cracking, and dimensional inconsistencies. It naturally reduces raw material waste, especially when processing engineering plastics, resulting in significant cost savings. Therefore, choosing our chiller can help you improve product quality while controlling production costs.
By keeping equipment and molds evenly cool, chillers help you avoid hot spots that can cause cracking or early wear. Your machines last longer, you spend less on repairs and spare parts, and the line keeps moving without costly interruptions. That’s long-term savings and steady production you can count on.
Our chillers use high-efficiency heat exchangers, and you can add a variable frequency control system that automatically adjusts power. This setup cuts energy use by up to 30%. So, you end up saving on operating costs without losing cooling performance. What’s more, the refrigerant we use is non-toxic and pollution-free, so it meets all modern green manufacturing standards.
Plastic-process chillers require no complex piping planning, making on-site installation easy. Routine maintenance is also very simple. At the same time, equipped with a digital control system, even non-professional operators can quickly learn to use it. It can display and adjust cooling water temperature, operating status, and alarm information in real time, allowing for convenient unified monitoring.
Reliable Certification
Featuring ISO and CE approval, these chillers maintain steady performance while abiding by global regulations for plastic manufacturing.
Areas of Use of Chillers in Plastic Processes
Cooling takes up almost 90% of the injection molding cycle, so cooling speed has a huge impact on your output. A chiller provides steady, uniform cooling water to the mold, thus your parts set faster and you can turn over more cycles in less time.
A chiller continuously cools the extruded tubing or film, guaranteeing your product quickly stabilizes its shape during the setting stage. Besides, precise temperature control makes your extrusion line run more smoothly, cutting downtime, helping you maintain consistent delivery quality, and diminishing rework and customer complaints.
In rotational molding, the mold spins inside a drum, making sure the molten plastic coats the mold evenly. If the cooling isn’t even, you get warped products or uneven walls. A chiller steps in here, helping the plastic solidify at just the right speed. That gives you stronger parts with a better finish.
A chiller can be used in conjunction with blow molding processes to cool and dehumidify the air, preventing moisture from affecting bottle quality. Also, it can precisely control mold temperature, resulting in more uniform bottle wall thickness and higher transparency. It is a wise option to enhance the market competitiveness of your packaging bottles.
During thermoforming, you need to cool those heated plastic sheets quickly and evenly, or else your product dimensions and quality suffer. A chiller provides a stable water temperature to the mold and cooling rollers, ensuring synchronized cooling of the entire sheet. Finally, every product comes out consistently, and you boost your production speed.
Most plastic processing equipment relies on hydraulic systems, and the hydraulic oil temperature should ideally be kept below 60°C. Excessive oil temperature will cause unstable pressure and even damage to pumps and valves. Chillers can effectively cool the hydraulic oil, keeping the system operating under ideal conditions and lowering your maintenance expenses.

Why Does the Plastic Process Need Chillers
When with plastics, you start by heating and melting raw materials. Then, you shape them—maybe by injection molding, extrusion, or blow molding. If you don’t cool things down properly, you run into trouble fast. Molds and equipment age faster, break down more often, you’re shelling out more for repairs and wasting time.
That’s where chillers come in. They keep your molds and equipment at just the right temperature, all the time. With steady cooling, you speed up the molding cycle. And, you end up with more consistent, higher-quality products. In a tough market, that edge really matters.
Air-cooled chillers use fans to get rid of heat. They work well with smaller equipment or in places where water’s in short supply. They’re easy to install, but if the factory gets really hot, their cooling power drops.
Water-cooled chillers dissipate heat through water. They handle bigger loads and are great for non-stop, high-output production. But they require water towers and extra piping, so you’ll spend a bit more upfront.
The ideal temperature range is between 7 and 15°C. Excessive temperature will prolong the molding cycle time, while excessively low temperature may cause condensation, affecting equipment safety. Maintaining a temperature difference of 3-5°C between the inlet and outlet water is optimal, as this balances cooling efficiency with system load.
Yes, as long as the chiller has enough cooling power. Central water chillers can handle several machines at once. Just make sure you add up the heat output from all your equipment and choose a chiller that can keep up, so every machine gets the cooling it needs.
You can clean the filter with compressed air every month and the radiator every six months. Also, check the water quality regularly and change the circulating water every three months to prevent scale buildup. What’s more, shut off the water supply before shutting down the machine to prevent condensation and rust inside the mold.
It might be that the cooling capacity of the chiller is insufficient or the pipes are clogged, which affects heat dissipation. In addition, excessively high working environment temperatures can also affect the cooling effect. You’d better check the status of the waterway and equipment, and then consider whether to increase the power of the chiller.
First, figure out how much cooling you need and think about your factory’s environment and how long your process runs. Both injection molding and extrusion need tight temperature control, so industrial chillers are your best bet. After that, decide between air or water cooling based on your site setup.
