Problems solved by technology

The compression molding steps of its production are as follows: first lay the glass yarn prepreg in the cavity of the lower mold of the mold, lay iron sheets or orderly arranged magnets and magnet and iron sheet combinations on the prepreg, and then place After the glass yarn is evenly spread on the prepreg, use a high-pressure spray gun to evenly spray the prepared resin glue on the glass yarn. After reaching the required thickness, the mold is closed, and it is cured for a certain period of time with a certain pressure and temperature, and then taken out. The main disadvantages of the suction device after grinding are poor light resistance, dirt is easy to show, and the production method of molding is extremely inefficient, and it has high requirements for process equipment (such as spraying equipment), mass production equipment The investment is large, the site demand is large, and the energy consumption is high, so the production cost is increased
