The customer means that the plastic panel can (but not must) be locked on the sheet metal panel with screws. I still suggest you to put a sheet of double side adhesive (3M brand is ok but expensive) on the inner side of plastic.
The aluminium part is extruded (铝挤出成型). The tooling cost is around 1500~2000RMB.
Cutting the extra area on the aluminium extruded. Drill M4 thread in holes.
Pls see the picture. Hope it can help you enough.

楼上的分析有道理。但是现在讨论的是在结构上如何实现客户的要求,我们帮想办法实现。所以示意图就够了,细节方面由她自己考虑。
透明塑胶板,尺寸这么大,又是平板,背面要丝印,所以开模具是不太现实的。从图片上看,这个产品好像是UPS,或者工控机(没仔细看),应该不会像玩具、游戏机那样大量生产,所以,从中小批量上衡量,用激光切割、CNC雕刻的方法比较好。单件、中、大批量都可以。(成本也低,不是象普通激光雕刻、CNC铣那样昂贵.)
塑胶背面丝印图案,没有问题,要看不到黑色的金属,在丝印工艺上可以解决。这方法我们经常用。客户的要求(Transparent plastic sheet painting on rear side with color and graphics.)可以实现。
