Acrylic processing in bending the details of expos |
You know some of acrylic products are not positive affirmative side, there are a lot of curved or winding. Like some acrylic products are acrylic processing hot bending process. In front of the article speaks of acrylic products bending process http://www.yyfchina.com/view_1010.html mentioned acrylic processing local bending and bending, the two bending mode are based on acrylic products different needs and use of acrylic processing technology. In this paper mainly talked about acrylic bending in some detail. First of all, in the acrylic bending, the oven to better quality, but also to ensure the surrounding environment is very clean ( avoid Rewan acrylic products have impurities). Then according to the design of acrylic products, size of drawing cutting and bending shape of die is long wide more than1CM acrylic sheet. Next is the tear to acrylic sheet above the tape ( in acrylic products technology introduction to http://www.yyfchina.com/view_1006.html about overheat bending to the paper, in the oven ). In in the oven should pay attention to some details: oven temperature should be controlled at 120degrees to 150 degrees, the temperature is too high will make the acrylic plate hot melt is more serious, sustained high temperature temperature may make acrylic yellow and black, so must control temperature; the temperature in the oven too acrylic sheet can not be designed in accordance with the shape bending in place; the optimal temperature control in soft degree should be able to change to the diagonal, it can immediately restore, raised in order to roast when facing up, so that the baking process will not hurt the acrylic panels. Roasted to a certain degree, out of state of hot melt acrylic to prepared mold, cooling into the required shape. |
