Thermoforming Acrylic Sheet

J.K thermoforming acrylic sheet is kind of extruded product, which combine PMMA resign and different scale of diffusion agent, features distinct high light diffusion and high light transmission. It’s kind of translucent milk white material, which one side is matte, another side looks like orange peel texture. It’s an idea lampshade material for LED ceiling light.
Length: Made as customer’s demand
Width: 900mm-1350mm
Thickness: 1.8mm, 2mm, 2.2mm, 2.5mm, 3mm
For small size, saw cutting service is available.
Light weight, weather resistance ( at least 5 years ), good light efficiency, light transmittance can be 80%-90% after forming to lampshade, and light is uniform and soft.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

Development Background of LED Diffuser Sheet

Led diffuser plate  is an important part from the past to now. Glass was used as the lampshade initially, but the glass was not brittle and the diffusion effect of light was not very good. It was difficult to meet the lighting requirements. Later, it gradually developed to replace glass with resin, but if only transparent resin lampshade, although the light transmittance is high, the basic can reach more than 90%, but the light diffusion effect is not ideal, poor light concealment. The white resin, whose light transmittance is too low, seriously affects the illumination of the LED lamp. In this case, techniques such as adding milky white pigments and surface scrubbing aids are used. Although this solves the issue of light source shielding, there is an excessively low light transmittance, which seriously affects the efficacy of LED lighting. Therefore, the problem of diffusion masks has been plagued by problems. In such a contradictory problem of light rate and light source shieldin...

Is Acrylic Suitable for Lights?

When decorating a room, in addition to some decoration materials, you also need to install lamps and lanterns. Because lamps and lanterns are very important in people's life and can provide lighting. In the dark night, you can work and live as in the daytime. In recent years, acrylic lamps are especially popular. There are many types of acrylic lamps, and people may not know how to choose when they are choosing. In this blog post, I will give you details on how to choose acrylic lights and what to look for when installing acrylic lights .   The advantages of acrylic lights Color The color is very durable. Acrylic panels are glossy, bright and colorful, and the colors are durable for 5-8 years. In other words, it will not change or fade in 5-8 years. Transparent High light transmission. Transparent  acrylic sheets  provide over 90% light transmission. The built-in light source provides uniform and soft nighttime brightness. Compared to neon, acrylic letters as a whole are ...
