Why does a high-speed 20-63mm HDPE pipe production line need to cool the pipe before vacuum forming?

In today's growing plastic pipe industry the manufacturers need to balance sped and quality to stay ahead among to their competitors. Jiangsu Xinhe intelligent equipment Co., Ltd meets this challenge with the advanced high sped HDPE pipe production lines capable of reaching impressive speeds of up to 30 meters per minute. The level of performances showcase the company leadership and in extrusion technology., However with such a high speed system this ensures the pipes maintain their shape and quality before vacuum forming.

1. Overcoming Physical Limitations: The Need for Active Cooling

When running speed at as high as 30 meter per minute, the traditional air cooling simply cant keep up. The short distance between the extrusion die and the vacuum forming doesn't allow enough time for the pipe to cool properly so since it passes through this area just a few seconds, to solve this issue the Jiangsu Xinhe develop a precise water cooling system that can quickly lower the pipes temperature from around 180 to 220celcuis to a stable level suitable for shaping. this active cooling method ensures that pipe stay firm and smooth and perfectly working around as it moves into vacuum calibration stage. So without this controlled cooling the pipe would not be over heat and lose its shape and develop surface flaws. By using this kind of advance water the cooling technology guarantees consistent quality and efficiency even at the fastest production speeds

2. Preserving Structural Integrity: Protecting Thin-Walled Pipes

HDPE pipes with the diameter of 20 o 63mm are the thin welled and it can easily deforms during a high speed production, if they enter the vacuum calibration tank is too hot and the combination of heat and vacuum pressure can collapse or flatten them. Xinhes pre cooling system is lower the pipes surface and the temperature to form a stable outer layers while keeping the surface inside warm enough for proper shaping. This careful temperature control procedures pipe’s that are round and accurate sizes because they need to be uniform in wall thickness to meet the standards needed for pressure rated application.

Xinhe's Integrated Cooling Technology

A recognize high tech enterprises with multiple invention patents has created advanced cooling solution designed specifically for high speed HDPE high production . Their system use carefully engineered water cooling rings that evenly cools pipes preventing issues like wrapping or distortion caused by uneven temperature. THE companies production lines features fully integrated temperature control that works seamlessly with the extrusion and the vacuum forming process ensuring the consistent quality even top speeds. With this innovation has earned trust of the manufacturers in Vietnam Indonesia and other middle east country.
