What are the characteristics of ULTEM glasses frames？

1. Plastic-steel glasses are lighter than TR90 plastic titanium. They have a more metallic texture, and the appearance is more upscale and elegant. The appearance of TR90 plastic titanium looks no different from ordinary plastics. There is no high-end taste.

2. Plastic steel glasses are beautiful and light. The average weight of each frame is only about 9 grams, which is only one-third of the weight of ordinary frames. No more burden on the bridge of the nose and ears.

3. Plastic steel glasses have strong flexibility and can be bent 360°, so the integrity of the glasses frame can be guaranteed. This feature allows sports-loving people not to worry about the deformation of the glasses due to collision, nor to worry about the deformation of the glasses when the cute baby is grabbing and pulling the glasses. They are not afraid of the glasses being deformed when they are too tired to fall on the bed or sleeping on the table.

4. Plastic-steel glasses, the frame is as thin as a steel sheet, and the surface hardness is like steel. Scratching with a fingernail or a sharp object will not leave marks.

5. Process of plastic steel glasses: The principle of plastic steel is the same as that of ordinary plastic products, and both need to be injected with the process of injection molding machine. In different points, the melting point of plastic steel in Wenzhou is much higher than that of ordinary plastics. Ordinary glasses plastics are generally around 260 degrees, and the plastic steel glasses materials need to reach 380 degrees. Another problem arises, that is, the inner part of the injection molding machine. All plastic pipes must be modified into materials that can withstand 380 degrees Wenzhou and can work normally. Because of this characteristic, the general factory to produce this kind of product requires a professional and experienced teacher to modify the machine.
