How is a pair of ultra-light TR material eyeglass frames made? First, let's explain. Eyeglasses frames on eyeglass mart are mainly classified into metal, plastic, and natural materials based on their materials. The mainstream plastic materials include TR, PV, and sheet metal.

TR is a type of memory polymer material, also known as "memory plastic", which is currently the most popular on eyeglass mart and widely used ultra lightweight eyeglasses frame material.

The biggest feature of TR material is its lightness, which makes it quite comfortable to wear. Elastic and not easily deformed, very resistant to compression. There are fruit-colored, transparent, glossy, and frosted textures, with many varieties suitable for all ages and populations.

The materials themselves also have certain differences, and the production of TR frames mainly involves mold casting. Heat the raw materials, pour them into ready-made molds, use machines to extrude them, and then polish, paint, and assemble them.

Among all the manufacturing methods of glasses, the TR frame manufacturing process has the highest machine involvement and the lowest manual involvement, so the manufacturing cost is low and the price is relatively cheap.

By the way, the more expensive the glasses are, the more delicate the craftsmanship is. For example, the processing accuracy of each connecting part can be seen in the processing accuracy of concealed parts or screws.

So how is a high-quality pair of TR glasses produced on eyeglass mart? Of course, the first step is to clarify the design and positioning, such as the age, occupation, and other characteristics of the main users of this eyeglass frame.

This determines what material to use, whether to use the natural color of the material or spray paint later, and whether the spraying process is based on high or low standards. These factors all determine the service life of the eyeglasses frame, especially how long it should be worn without peeling off the paint.
