Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass. The lighting made of acrylic has good light transmission performance, rich colors, beautiful and smooth, can take into account both day and night effects, and has a long service life.

The production methods of acrylic sheet mainly include: casting molding, injection molding, extrusion molding and thermoforming. There are four flowers, one for each table, and four different production processes are introduced below.

Casting molding production method

Casting method - casting requires the use of molds. The texture, shape and structure of the processed products are very complex, so the production scale is suitable for small batch production. The products produced by casting method have high toughness and strength, and also have good decoration. Therefore, the casting method is often used in manufacturing and decoration industries. Casting products need to be post treated after treatment, and then the treatment conditions are incubated at 60 ℃ for 2 hours and at 120 ℃ for 2 hours.

Extrusion molding method

Polymethyl methacrylate can also be prepared by extrusion molding. The particles prepared by suspension polymerization can be used to prepare plexiglass plates, rods, tubes, sheets, etc.. Extrusion can be carried out by single or double stage exhaust extruder, and the length diameter ratio of screw is 20-25.

Extrusion to achieve large-scale, large-scale mass production. The reason is that the extrusion method can be fully automated,and the advantages is that the processing is flexible.

Injection molding production method

Injection molding uses granular materials that are formed on a common plunger or screw injection molding machine. Typical process conditions of injection molding: the injection molding products also need to eliminate the internal stress. In the process, the processing is carried out in the hot air circulation oven at 70-80 ° C. the processing time depends on the product thickness, and generally takes about 4 hours.
