How long is the cooling time required for the molding machine?

2020-09-23

When using the cooling modification of the molding machine to carry out the hot shaping, the temperature control will determine its qualitative quality. After thermal setting, the degree of elimination of wrinkles on the original surface of the fabric, the improvement of surface evenness, the dimensional thermal stability of the fabric and other wearability are all closely related to the temperature of thermal setting. Then how long is the time needed for the molding machine cooling transformation? The following molding machine reconstruction manufacturers will be introduced for you:

Molding machine cooling modification


1. Heating time: After the fabric enters the heating zone, the time required to heat the fabric surface to the setting temperature.


2. Heat penetration time: After the surface of the fabric reaches the setting temperature, the heat penetration time required to make all the fibers in and out of the fabric have the same setting temperature.


3. Molecular adjustment time: The time required to adjust the molecules in the fiber according to the setting conditions after the fabric reaches the setting temperature.


4. Cooling time: The time it takes to cool the fabric out of the dryer to fix the fabric size.


5. Before setting, it should be heated to a certain temperature. Therefore, the setting time is another important process condition for the heat setting of the tensioning machine. After the fabric enters the heating zone, the time needed for heating and setting can be divided into the following parts: heating time, heat permeation time, molecular adjustment time and cooling time.


Tensioning frame usually refers to the setting time, often refers to the first three required time, to a certain extent does not include the fourth item. If one term is considered as a warm-up, then the setting time refers only to the time required for the second and third terms, namely, the time required for thermal penetration and molecular adjustment.


The above is about the molding machine cooling transformation time needed to introduce, want to know more about the molding machine transformation engineering related issues, welcome to inquire about our official website, we will explain in detail for you.
