Market Application and Classification of Laboratory High Temperature Vacuum Hot Press

Application of laboratory press: 5G communication materials, aerospace materials, marine new materials, polymer materials, automotive materials, high-speed rail new materials and other fields.

Press according to the different heating methods, the current main types can be divided:
Electric heating: this is the early heating method, but because the temperature is not stable, has been rarely used;
Hot kerosene heating: the heat medium oil is heated by the boiler, and then the heat medium oil transfers the heat to the press. Because the heat provided is stable, it is easy to control the rise and fall, and most presses currently use this heating method.

Vacuum hot press pressure up mode: at present, most presses are pressurized by hydraulic pressure, and the pressure source is implemented by a cylindrical cylinder from bottom to top.

Vacuum hot press control points
Vacuum: After entering the press and before starting to press, vacuum it to avoid residual bubbles during the pressing process;
Time: the slope and holding time of temperature and pressure in each stage, which mainly affect the heating rate and curing time;
Pressure: the pressure on the production board at each stage, which mainly affects the flow of glue and stress release of the production board;
Temperature: The temperature of the hot plate of the press at each stage mainly affects the actual temperature of the production plate.
