How to solve the problem of drilling and bursting in acrylic panel processing

Acrylic panel drilling is a very common process, but many customers report that the acrylic panel will burst once the hole is drilled. So how did the explosion happen and what should be done about it? The following is a brief summary of Sunday Knight Co Ltd for your reference:

1. The acrylic panel will burst after drilling holes, which is generally caused by improper operation. The thermal expansion coefficient of acrylic panels is very large, generally nine times that of metal. Therefore, when drilling holes in acrylic panels, pay attention to certain To leave a gap for the expansion and contraction of the acrylic panel, punch a larger hole; there is also a case of bursting when the screw is tightened too tightly; in addition, do not get too close to the edge when drilling a simple hole.
2. Use an ordinary twist drill bit, grind it into a three-pointed shape, and the middle point is slightly higher, so that the drill bit can drill the plexiglass well. Or use a hand-crank drill. When drilling, the force should be uniform, and the pores left under the glass plate should be small to enhance the strength of the glass. You can also put some sand on the glass to increase the friction.
3. The drilled position cannot be scrubbed with alcohol, otherwise it is easy to burst.
4. The choice of better acrylic plexiglass sheet is the basic guarantee to avoid bursting.
