The so-called "workers who want to do well must first sharpen their tools." In wood processing enterprises, a good hot press hydraulic station product is the key to whether an enterprise can produce high-quality products, and it is also the lifeline of an enterprise.


In the process of pressing plates by the hot press, the hydraulic system is the key to the operation of the entire hot press. Just like the human brain, the production of high-quality wood products requires that the hydraulic system of the hot press meet the following requirements:


1. The quality of hydraulic medium


The heating medium of the hot press system can be steam, water, soapy water, emulsion, hydraulic oil, etc., but different media have different levels of cost and effect. The price of water, steam and other media is low, but it is highly corrosive to hydraulic components, and the cost of hydraulic oil is high, but it has a series of advantages such as good stability, non-corrosiveness, lubrication, and high safety factor. It is currently very popular in the industry.


2. Hydraulic time


After the glue is applied, the boards will solidify in a limited time. Therefore, the shorter the closing time of the hydraulic system, the better the bonding between the boards and the improvement of product quality.


3. Pressure compensation system


After the hot press is closed, the hot oil provides proper pressure through the squeeze plunger cylinder, but it needs to be supplemented from time to time to prevent the pressure drop from causing insufficient sheet gluing, causing cracking and cracking.


4. Step-down pressure


After the hot pressing of the slab is completed, the pressure of the cylinder is reduced. In order to avoid defects, the pressure reduction needs to be controlled and the pressure is reduced in stages.


If the control of the hydraulic system achieves the above 4 points, then the pressing force of the sheet can definitely meet the needs of forming, while ensuring the strength of glue solidification and improving product quality.
