O tanque de resfriamento é usado para resfriar as longas tiras de plástico macio extrudadas pela máquina auxiliar do peletizador para facilitar o corte pela máquina de corte de pellets de plástico.
A plastic cooling equipment is an essential piece of equipment widely used in plastic recycling, pelletizing, and extrusion production. Its main purpose is to rapidly cool hot plastic strands or pellets after extrusion or cutting. The use of a cooling tank ensures that the product solidifies uniformly, retains its shape, and is ready for further processing such as drying, conveying, or packaging.
Introduction to the Cooling Tank
A cooling machine is an important machine in a plastic film recycling line, which can cool and shape the long strips of high-temperature plastic.
Shuliy Machinery has many years of experience in manufacturing cooling water tanks. If you are engaged in the plastic recycling business and need to use a cooling machine, please contact us.
Parameters of the Cooling Water Tank
Generally, the plastic cooling machine of Shuliy Machinery is 2.5m long and 0.4m wide, made of stainless steel.

Of course, if you have special requirements, we can make it according to your needs.
Working Principle of Plastic Pelletizing Cooling Tank
In a plastic pelletizing cooling tank, hot plastic pellets or strands are submerged in circulating cooling water.
Process flow of the plastic cooling machine:
Step 1：
- Hot plastic pellets enter the tank and are immediately submerged to remove heat.
Step 2:
- Circulating water absorbs the heat and keeps the pellets at uniform, safe temperatures.
Step 3:
- Solidified pellets exit the cooling tank ready for drying, cutting, or packaging.
The pelletizing line cooling system prevents agglomeration of pellets and ensures their shape consistency for high-quality end products.
Structure and Features of Stainless Steel Cooling Tank
The plastic cooling machine manufactured by Shuliy Machinery is made of stainless steel. On the one hand, the stainless steel material can withstand the high-temperature plastic long time, making it less prone to deformation. On the other hand, the stainless steel surface is smooth, not easily adhering to dirt, and easy to clean.
- High-grade stainless steel tank body: Ensures corrosion resistance and hygiene, is easy to clean and maintain.
- Reinforced frame and adjustable feet: Provides stability on various factory floors.
- Customizable dimensions: Length, width, and depth can be tailored for your production line.
Importance and Applications of Industrial Cooling Tank
A temperatura da tira plástica derretida é muito alta e facilmente deformada, então o máquina de corte de pelotas de plástico cannot cut the strip into small particles; it needs to be cooled first.
The industrial cooling tank is suitable for:
- Plastic pelletizing cooling systems: For PP, PE, PET, PVC, ABS, and other plastics.
- Plastic extrusion cooling systems: For pipes, profiles, sheets, and filaments.
- Cable and rubber extrusion cooling lines: Ensures shape and strength before winding or cutting.
Location of Plastic Cooling Machine in the Plastic Pelletizing Line
O tanque de água de resfriamento é colocado após o máquina granuladora de plástico e antes do máquina de corte de pelotas de plástico. The high-temperature plastic strips extruded from the pelletizer auxiliary machine enter the cooling water tank directly, and the cooled plastic strips are conveyed through the machine to the pelletizer.
How to Select the Right Strand Cooling Bath
Choosing the correct cooling bath for plastic extrusion for your production line involves:
- Material type and cooling needs (e.g., PP vs. PET require different cooling lengths).
- Production capacity and line speed are used to determine tank size.
- Available space in your facility and layout considerations.
