Lights glass lens manufacturer Shenzhen Ming Jin Ze Technology produces all kinds of lights glass lens

Product Name: street glass lens Product Type: JMZ92-1 Material: High borosilicate 3.3 products transmittance: 95% Beam Angle: 65 * 120 Accessories: stainless steel pressure box, high-quality silicone ring, reflectors Application: 10W- 100W high power street light / tunnel light / explosion-proof lights and other original glass lens molding method, is the optical glass blanks into the molten state is higher than the glass transition point above 50 ℃ low temperature mold press forming. This approach not only prone to sticking in the mold of glass mold surface, and products are also prone to porosity and chill marks (wrinkle) and difficult to obtain the desired shape and surface accuracy. Later, using special materials, precision machining into a pressure-type mold, non-oxidizing atmosphere in the environment, the heated glass and the mold was heated to near the softening point of the glass, the glass and the mold is at approximately the same temperature, using a mold of glass pressure. Viscosity of the glass softening point of the next while cooling the mold while keeping the applied pressure state so that the temperature was lowered glass transition point of about 107.6 less glass, a glass transition point of the glass when the viscosity of approximately 1013.4 poise). This will be implemented together with the mold temperature and pressure, such as glass approach called isothermal pressure method is relatively easy to obtain a precision that is easy to precisely replicate the shape of the mold surface down approach. The disadvantage of this method for manufacturing glass optical parts are: heating up, cooling down will take a long time so the production is very slow. To solve this problem, so this method was effective improvements, namely in the molding apparatus with a plurality of mold, to improve production efficiency. However, the high cost of mold aspherical mold will inevitably result in the use of multiple high costs.
