Copper Clad Laminate Press

2022-03-23 15:33

The copper clad laminate press unit consists of a hot press, a cold press, a hydraulic system, an electronic control system, a mobile loading and unloading trolley, a loading rack, a unloading rack, a temporary storage rack, a vacuum system, a backing plate return device, a vacuum suction cup sports car, and a hydraulic system, Electric control system and temperature control system are composed, which have the advantages of high precision, good rigidity, good control, easy use, high product quality, and large output. The main cylinder after 35 ~ 40Mpa high pressure test, pressure reliable; the sealing structure through the optimization design and selection of imported sealing ring, reliable sealing, the use of general up to 3 to 5 years. The electric control system is equipped with: PLC programmable controller, man-machine interface and temperature inspection instrument; pressure, temperature, time and other process parameters and the working state of the press can be set, modified, consulted and printed at any time, and the operation is extremely convenient and intuitive.

The pressing process of copper clad laminate press is completed through three different process control stages: pre-temperature, hot pressing and cooling. The whole stage of processing mainly includes several main processes such as shearing (cutting), laminating (layup), laminating (lamination) and unloading of the adhesive tape. In this production process of copper clad laminate, the lamination of glass fiber cloth and copper foil is a key step. The lamination process uses a hot press, and the heat transfer medium currently uses heat transfer oil.
The high temperature synthetic heat transfer oil is used as the heat medium, which is transported by forced convection, and the heat is transferred to the hot pressing plate in an indirect way. Electric heating heat conduction oil furnace is economical, environmentally friendly and energy-saving, so the heating method of heat conduction oil as a heat source has gradually replaced steam and electric heating methods. Most manufacturers at home and abroad can achieve direct high temperature, high pressure lamination process. In order to improve the performance of the board, the "two-step method" is generally used in the lamination process of glass fiber cloth based copper clad laminate ". That is, the pre-temperature stage of pressing is carried out at a lower temperature and low pressure, and then high pressure and temperature rise are added to complete the processing of the curing molding of the plate.
