Acrylic is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, is easy to dye, easy to process, and has a beautiful appearance. Many acrylic products appear in daily life. With the continuous improvement of the industrial level, the shape and shape that acrylic can do has increased, and the shaped acrylic products have gradually become mainstream.
There are several major additions to the profiled acrylic:
Hot bending is generally used in two types: local hot bending and model bending. The local hot bend is to place the portion of the acrylic that is to be hot-bent on the heated heating rod. Slowly heat the heating rod to soften the area where the acrylic is to be bent, and then bend it into any shape you want. The model hot bending is to put the acrylic to be bent into the oven, and slowly increase the temperature. After the acrylic softens, take it out and put it on the mold that has been prepared beforehand. After cooling, it can be formed.
2. Hot melt
The acrylic is heated to a certain temperature, and the hand is quickly put into shape and kneaded by hand. It is required to have a good composition in advance, and the movement is quick and in one go, and the finished crafts have the advantages of unrestrained lines and simple image.
CNC engraving generally adopts a back carving method, that is, engraving from the front and rear viewing, which makes the finished product more three-dimensional. Please mirror the graphics in the back carving, and the carving speed is faster and the power is lower. If the power is too high when engraving, there will be uneven stripes on the bottom surface. If you want to dig deeper, try to sculpt several times.
Acrylic will be affected by temperature. The temperature during the hot melt process is generally around 150 °C, but when the acrylic begins to decompose, the hot bend acrylic processing, the temperature is higher than 270 ° C, so in terms of temperature changes Still very flexible.
