Study On Injection Molding Of Optical Parts


Optical lens (glass) is widely used in various fields, is a variety of precision equipment, the core parts, and optical components injection molding is a variety of plastic products manufacturing methods of mass production. This paper will discuss the difference between the injection Optical Products Component Injection Molding molding of traditional optical product parts and the injection molding of precision optical products from six aspects, and explain the feasibility of injection molding of optical lens optical components and hope to be widely used.

With the rapid development of imaging technology, people can anytime, anywhere around what is happening, scenes and characters recorded in their own camera or mobile phone. And these high-tech products, the core parts is a high-precision optical components. In recent years, Optical Products Component Injection Molding people have begun to use polymer materials instead of glass lenses, and gradually applied in the communications industry, medical equipment, cars, cars, and so on. Industry, and information industry. And whether the realization of mass production is the key to optical components injection molding.

As we all know, optical components injection molding is widely used in mass production of plastic parts, Optical Products Component Injection Molding but the traditional optical components injection molding technology difficult to achieve the accuracy of optical components. To achieve the required dimensional tolerances and surface quality, the entire process chain must be optimized. After years of research, Optical Products Component Injection Molding can now be precision optical components through the injection molding technology to create more functional, Optical Products Component Injection Molding reasonable price of precision optical components to meet the needs of the market.

In the optical product parts injection molding process, because it can not be marked on its surface, so the mold cavity pressure measurement is limited. However, Optical Products Component Injection Molding in order to use this important process parameter for quality monitoring, a non-contact measurement method using a special measuring pin is used to measure the cavity pressure. Coupled flow paths to the pvT diagram to develop new processing and monitoring techniques.

This does not include high quality optical components, on the contrary, Optical Products Component Injection Molding just can use the highest quality level to produce the practical application of optical components. In terms of prisms, not only does its geometry and surface structure play an important role, but the reproducibility of production can also greatly affect the internal performance of products such as internal stress or molecular orientation. Therefore, for example, it is not enough to check the geometry of the part or to visually inspect the part surface in order to assess the optical performance of the product during the production process. Optical Products Component Injection Molding The determination of optical performance is even more important. For example, the twist of the wavefront measured by the Shack-Hartmann sensor (SHS) can be used as a result of the determination. Mathematical methods can be used to deduce a more important quality function.

During the injection molding of optical components, the molding process has an impact not only on its geometry but also on the internal performance of the components. Research on component quality has shown that the change from injection molding to injection-compression molding can only slightly increase the geometry of the part. However, its optical properties are probably able to improve the seven factors, so only by testing the geometric parameters to evaluate the optical properties of components is not enough. Thus proving that injection molding of optical components is a suitable method for processing optical components. During the pressurization process, the pressure phase is applied directly after the compression phase.

In the process of injection molding of optical components, the three-dimensional problem areas must be managed: the geometrical, surface and optical properties of the components must be included in the quality assessment of the desired product. This requires precise process control, that is, Optical Products Component Injection Molding the known mold state and the existing process. These speculations require knowledge of cavity pressure. Because the cavity pressure accurately reflects the filling, compression and packing stages during injection molding, these information are helpful during process optimization and for processing and quality monitoring.
