thick wall transparent lens light guide strip optical injection molding machine
injection molding system is equipped with special plasticizing components, injection control, anaerobic plasticizing, low-speed and high-pressure injection molding, dynamic variable temperature injection molding, injection compression and other functions. Since 2010, it has served Mercedes-Benz, BMW, Volkswagen, Great Wall, Changan, GM, Ford, Honda, Nissan, Geely and many other automobile brands.
For thick-walled transparent optical injection molding, shrinkage, flow marks and white crystals need to be effectively solved. As well as the yellowing, light transmittance, black spots, black fog and other problems of the light guide strip, the Echos team has developed a variety of solutions, such as: low-speed and high-pressure injection molding (the minimum stable adjustable speed is 0.1 mm/s, and the maximum injection pressure is as high as 4000bar), which effectively relieves the problems of glue flow pattern and record pattern during the injection molding process, at the same time, there are starvation feeding, anaerobic plasticization, injection compression, precise melt metering, low-speed injection molding, low-inertia motion control, high-pressure PVT molding and other processes. With special plasticizing components, it can effectively deal with bubbles, white mist, shrinkage and other problems. The functions of anaerobic plasticization and starvation feeding make the instant molding cycle of PC materials as high as 20min can maintain no yellow edges and no bubbles, and inhibit the generation of decomposition gas scale of raw materials, so as to improve the quality and qualification rate of products.
1. Universal transparent thick-wall optical injection molding machine series, with clamping force ranging from 40 tons to 2500 tons, is used for conventional transparent optical injection molding.
2. The series of double-shot optical injection molding machines have a clamping force ranging from 240 tons to 2500 tons. On the basis of the conventional transparent optical injection molding machine, two injection tables are configured, which can quickly switch and choose to use different injection tables. The common applicable scenarios are: A. PC or PMMA is sometimes used for injection molded optical products. When the conventional injection molding machine changes the injection molding materials, it takes a lot of time and expensive raw materials to clean the screw barrel, and it is difficult to ensure whether the cleaning is completely clean. When two sets of injection units are provided, the two barrel screws can be distinguished and applied, quickly switched, economical and efficient. Application scenario B: one injection molding machine is selected, but the size and configuration of the screws of the two injection molding units are different. when producing products with small injection weight, small products are switched, and large products are switched to large injection screws, so as to reasonably match the size of the injection molding screw, improve the qualified rate of the product, and improve the utilization rate of the equipment, at the same time, make the injection molding equipment in the workshop more flexible scheduling schedule, facilitate the production arrangement of orders, and improve economic benefits.; Applicable scenario C, when some products may use recycled materials or color materials in the mold testing stage, it is convenient to distinguish and use them. Genuine production uses another barrel to improve the economic benefits of production arrangement.
3. Multiple groups of layered injection molding systems, with clamping force ranging from 280-2500 tons, can be equipped with 2-4 injection molding units to realize high-efficiency and high-precision production of thick-walled products, such as thick-walled high-precision lenses, one machine It can realize single-layer, double-layer, three-layer, five-layer and other injection molding processes to achieve a high-efficiency production cycle, and unlike traditional two-color injection molding machines, this series of machines can be completely used as ordinary monochrome injection molding machines, the nozzle can be adjusted freely in the center and front and back deviation, realizing the injection molding operation of the mold with 1, 2, 3, 4 and 6 stations, so that the utilization rate of the machine can be fully utilized.
