Advantages of vacuum hot press oil heating

Vacuum hot pressThere are several kinds of heating methods. Today, I 'd like to introduce the advantages of oil heating. The heating form of the oil heating oil circulation temperature control machine is realized by the heat conduction oil circulation. The hot pressing plate itself has a thermal cycle. When the temperature of the hot pressing plate is lower than the set value, the oil circulation temperature control machine starts heating to maintain the temperature of the hot pressing plate within the set range. Usually, the temperature difference can be controlled within the range of ± 1 ℃ to meet the production requirements of high-end circuit boards and copper clad laminates.

When the vacuum hot press is cooled, the hot oil of the hot pressure plate is circulated through one or several heat exchangers, so that the hot oil is gradually cooled to achieve the purpose of gradually cooling the hot pressure plate. Since the cooling process has a certain impact on the warpage and dimensional stability of the product, the laminating machine has a variety of forms of cooling design. It must adapt to the process requirements of slow cooling first and then fast cooling to ensure product quality. The production cycle is too long, and at the same time it is conducive to energy saving. Because of its high temperature control accuracy, if the production needs higher heating temperature can also be achieved, because the thermal decomposition temperature of synthetic hot oil is above 310 ℃, and steam and superheated water can not be reached, and there are many domestic copper clad laminate plant using oil heating system. The advantages of oil circulation temperature control machine heating are: high heat capacity, uniform temperature, can be heated to a very high temperature under normal pressure, and low heat loss.
