Reputation depends on quality, quality comes from Hard!
Alumina ceramic polycarbonate occupies an extremely important position in this field due to its unique characteristics of high light transmittance, high refractive index, high impact resistance, dimensional stability and easy processing and molding. Optical lenses made of optical grade polycarbonate can be used not only for cameras, microscopes, telescopes and optical testing instruments, but also for film projector lenses, copier lenses, infrared auto-focusing projector lenses, laser beam printer lenses, and various Many office equipment and home appliances, such as prisms and polygon mirrors, have a very broad application market. Another important application field of polycarbonate in optical lenses is as a lens material for children's glasses, sunglasses and safety glasses, and adult glasses. The average annual growth rate of polycarbonate consumption in the world's optical industry has remained above 20%, showing great market vitality. With the rise of the information industry, optical discs made of optical grade polycarbonate, as a new generation of audio-visual information storage media, are developing rapidly at an extremely fast rate. Polycarbonate has become the main raw material of the world's optical disc manufacturing industry due to its excellent performance characteristics. The consumption of polycarbonate in the world's optical disc manufacturing industry has exceeded 20% of the overall consumption of polycarbonate, and its average annual growth rate has exceeded 10%. China’s CD production has grown rapidly. According to figures released by the State Press and Publication Administration, there were 748 CD production lines nationwide in 2002, which consumed about 80,000 tons of optical grade polycarbonate, all of which were imported. Therefore, the application prospect of polycarbonate in the field of optical disc manufacturing is extremely broad. It is used to manufacture large-scale lampshades, protective glasses, left and right eyepiece tubes of optical instruments, etc. It can also be widely used as transparent materials on airplanes. Polycarbonate is an excellent E (120°C) grade insulating material, used to manufacture insulating connectors, coil frames, tube sockets, insulating sleeves, telephone shells and parts, and battery shells for miner’s lamps. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, electronic computers, video recorders, telephone switches, signal relays and other communication equipment. Polycarbonate film is also widely used as capacitors, insulating bags, audio tapes, color video tapes, etc.
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.

SHENZHEN HARD PRECISION CERAMIC CO.,LTD
Shenzhen Hard precision ceramics Co., LTD. has been committed to design, development and manufacture of industrial ceramic products since 2007. Compared with metal, advanced ceramic has the following excellent performance: high hardness, high strength, high temperature (fire), and can wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, non-magnetic and good chemical stability . So it is often used in the environment where the metal material cannot endure. With its promising application , advanced ceramics are widely used in aerospace, aviation, military industry, nuclear power, machinery, textile, chemical, electronics, food, medical and other industries. Our advanced ceramic products made by zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products can divide into two parts: one part is ceramic ball, rods, tubes, ceramic materials such as plate, block, strip and so on, and the other part is the precision ceramic parts which are for industrial use and civilian products. Our company has advanced one-stop equipment and technology of ceramic forming, sintering and processing. Hope we can establish excellent cooperation with customers from at home and abroad for a wide range .
