Shenzhen acrylic lens processing process?

Acrylic lens processing flow

Processing prerequisites: receiving demand

Each company must design drawings when making acrylic lenses for themselves.According to the different drawings, we design different products.The drawings include length, width, thickness, product requirements, semicircular radius, or diameter, etc. and There are also requirements for the hardness of the product, and there are other requirements such as scratches.

Step 1: Acrylic board cutting

Use a laser cutting machine to cut the acrylic sheet into the product shape required by the drawing, to ensure a certain error, so that the error is not higher than 0.02mm;

Step 2: Drilling of acrylic plate

This acrylic plate drilling is an option.When we see acrylic lenses, the products that are usually made are directly electroplated and silk-screened. Drilled products are rarely seen, but there are also some needs. If there is a positioning column under the top frame, or there are novel ideas, you can achieve the effect of drilling by drilling.

Step 3: Acrylic board polishing

When making acrylic sheets into lenses, one of the most basic requirements is that there are no burrs around the acrylic sheet.When cutting, we often leave a few burrs.The appearance of these burrs will cause the burrs to be applied when coating After coating, the second possibility is that the burrs are easy to cut hands, which is also a heavy load that cannot be sustained by using acrylic boards.

Step four: hot press forming

Some acrylic lenses are not the same as common acrylic lenses. Most of the acrylic lenses are a PMMA plate, while some need to change the shape for some special reasons.At this time, we can heat the acrylic plate to make it hot-pressed. What customers want

Step 5: acrylic screen printing

This step is for customers to display their own brand LOGO or patent or text description added when declaring the brand. At this time, they will choose to add silk screen, and some products do not need to add silk screen, but most products will add silk screen because of display brand. There are two types of screen printing, one is: monochrome screen printing; the other is: four-color (CNYK) screen printing.

Step 6: Acrylic plate coating

This is the process of changing the acrylic plate into acrylic lenses. The usual method is electroplating of acrylic lenses, so that the acrylic plates can be converted into acrylic lenses. In addition, the acrylic lenses can be colored into a predetermined color. To achieve the desired effect, it can also be targeted The light transmittance of the window can be adjusted, such as no light transmission, semi-transparent acrylic lens, and full lens.
