Main technical parameters of plywood hot press machine
When selecting or evaluating a plywood hot press machine, one should not only look at the price, but also understand its several core technical parameters. These numbers directly determine what specifications of boards you can produce, how efficient they are, and whether the quality is stable or not.
The size and number of layers of the hot press plate are the most intuitive parameters. It determines how many sizes of plywood you can press at once and how many sheets you can press out at once. To produce large-sized boards or pursue output, it is necessary to choose equipment with sufficient size and layers.
Work pressure is the core source of power, usually measured in megapascals (MPa). This pressure value is responsible for tightly pressing the slab together, ensuring sufficient bonding strength, and avoiding glue cracking or delamination. Without sufficient pressure, product quality loses its foundation.
The heating method and temperature directly affect the curing quality and efficiency. The mainstream methods include electric heating, steam heating, and oil heating. What you need to pay attention to is the maximum working temperature of the hot press plate and the uniformity of temperature control. Uneven temperature can cause local non solidification or carbonization of the board, resulting in waste.
The closing speed and parallelism of the pressure plate are related to production efficiency and quality control. Quick closure can reduce heat loss and improve efficiency; The extremely high parallelism of the pressing plate is the key to ensuring uniform thickness and consistent stress on each slab, which is the bottom line for producing high-quality plywood.
The key parameters of the hot press include size, number of layers, working pressure, heating method and temperature uniformity, as well as closing speed and parallelism. They collectively determine the processing capability, efficiency, and finished product quality of the equipment. A deep understanding of these indicators is the foundation for equipment selection and ensuring stable production.
