1.What Is Thermoforming?

Plastic thermoforming is a manufacturing process in which a plastic sheet is heated to a pliable forming temperature, formed into a specific shape in a mold, and trimmed to produce a usable product. The process requires precise temperature control, especially during thin and thick plate plastic thermoforming, to improve process efficiency and product quality.

2.What is A Thermoforming Chiller?

A thermoforming chiller is a specialized type of chiller machine designed specifically for use in thermoforming processes. It is a refrigeration system that provides controlled and precise cooling to the molds and equipment used in thermoforming operations.

Thermoforming chillers work by circulating coolant through the cold side of the process water system, removing excess heat from the mold and transferring the heat to the surrounding environment.

When it comes to cooling your thermoforming process, quality and reliability should be your top considerations when choosing the right thermoforming chiller.

3.Why Need A Industrial Chiller Used In Thermoforming Process?

A thermoforming chiller is an essential part in thermoforming process, which contributing to the production of high-quality, dimensionally accurate, and aesthetically pleasing plastic parts. It plays a crucial role in controlling the temperature during the cooling phase of the process, which ultimately impacts the final quality and performance of the thermoformed products.

Cooling the Mold: Similar to other forming processes, thermoforming involves heating the material (in this case, thermoplastic sheet) to make it pliable and shapeable. Once the plastic sheet has been formed into the desired shape using a mold, it needs to cool and solidify quickly to maintain its shape. A thermoforming chiller provides the necessary cooling to achieve this.

Maintain accuracy and dimensional stability: Thermoformed parts often require precise dimensions and consistent quality. Proper cooling ensures that formed parts maintain their accurate shape and size, reducing the possibility of warping or deformation.

Reduce stress and improve material properties: Controlled and uniform cooling helps reduce thermal stress on formed parts. This is important to prevent defects such as cracks, warping, or surface imperfections. Furthermore, it helps achieve the desired material properties in the final product.

Enhanced surface finish: Rapid and controlled cooling helps achieve a smoother and more consistent surface finish on thermoformed parts. This is especially important for applications where appearance and aesthetics are critical.

Prevent equipment wear and damage: Proper cooling helps extend the life of thermoforming molds and equipment. Rapid cooling reduces the potential for thermal stress on the mold, which can lead to premature wear and damage.

4.What’s the Difference Between Air-cooled & Water-cooled Thermoforming Chillers?
There are two types of Injection Moldingchiller: one is air-cooled Thermoforming chiller ,the other is water-cooled Thermoforming chiller ;

Air-cooled Thermoforming chillers use ambient air to dissipate heat from the brewing processes. They are energy-efficient, space-saving, and less maintenance that helps save money.
Water-cooled Thermoforming chillers use water from an external water cooling tower to dissipate heat from the brewing processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled Thermoformingchiller.

5.What Are the Differences Between Thermoforming Scroll Chiller and Thermoforming Screw Chiller?

Thermoforming Scroll Chiller Thermoforming Screw Chiller

▪1/2 HP-60HP Above 60HP

▪ Danfoss/Panasonic Scroll Compressor Hanbell/Bitzer Screw compressor

▪Built with water tank and water pump Without water tank and water pump

6.What Are The Main Components of Thermoforming Chillers?

6.1 Compressor

The compressor is the key mover in water chiller because it produces pressure variations to stir the refrigerant around.

From 1/2HP(1/2 Ton) to 60HP(5oTon) Thermoformingchiller , which is with Panasonic or Danfoss brand Scroll compressor ,
Above 60HP Thermoformingchiller,which is with Hanbell or Bitzer screw compressor;

6.2 Evaporator

The evaporator is a crucial component of air-cooled water chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators : coil in water tank evaporator , shell and tube evaporator, 304SS stainless steel plate type evaporator.

6.3 Water Pump
The water pump is designed to increase the pressure and the flow of the chilled water in a closed space.

6.4 Condenser

The condenser for air-cooled Thermoforming cooler is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.

The condenser for water-cooled Thermoforming cooler is shell and tube ,with the internal copper tubes employing an outer thread embossing process.This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

8.How to Choose Right ThermoformingChiller for Your Thermoforming Process?

How to calculate right cooling capacity for your Thermoforming chillers?

Choosing the right size of an Thermoformingchiller is crucial for ensuring optimal performance and efficiency in your Thermoformingprocess. How to calculate the correct cooling capacity for your Thermoformingchiller,pls see below:

▷ pls tell us the production for your thermoforming machine;

▷ how many degree of outlet water temperature from the chiller you request ;

Types of Injection Moldingchiller system?
There are two types of chiller :Air Cooled Thermoforming Chiller and Water Cooled Thermoforming Chiller.

Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have exsiting water cooling tower,we suggest you use air cooled chiller; But if your ambiemt temperature is very high above 55℃ ,we suggest you use water cooled chiller , as it is easier to dissipate heat for water cooled chiller with water cooling tower.
But Most customers use air cooled Injection Moldingchiller ,which is more easily install and save space.

Whether chillers need built-in Tank or not？

In a chiller system, a tank is usually equipped to buffer the thermal load of the chiller.

But should we choose a built-in type of tank or an external type of tank?

A chiller with a built-in tank is easier to install and can be used simply by connecting a water pipe to your application.

But it has a limited capacity and is not suitable for applications with larger chilled water demands.External tank’s capacity can be customized according to specific needs.

It can buffer a larger heat load, store more chilled water, but the installation will be more troublesome.

If you don‘t have external water tank ,we suggest our chiller built-with water tank ,which is easy for you to install.
