After the plexiglass board is pressed, the bottom corner cracking problem is dealt with as follows:
1. The optimal time for pressing the bottom plate is controlled at about 2 minutes.
2. The four corners of the male mold of the bottom plate should be processed into inclined molds.
The uneven bottom of the plexiglass bottom plate is treated as follows:
Buy a wide-width vertical electric belt sander, and place the characters on the ground at the top of the bottom to increase the bonding contact area between the characters at the bottom and the bottom plate to make the bonding stronger.
The problem of uneven suction pressure on the surface of acrylic suction bag and its treatment:
1. Two 2X2 thick-walled square pipes can be used to cross at one-third of the angle, and the short end can be welded to the angle iron with a long screw engineer to increase the contact area at both ends and make the four chucks spare.
2. After the plate is softened, place it on the platform mold and use it as a good fixture to gently press the four sides of the plate. When the platform pressing mold is half completed, press the platform to the bottom until the plate is compacted.
