plastic Optics&len mould

GPT mold is one of the few manufacturers capable of producing high-precision plastic lenses using injection molding processes. The customer-specific products developed in our facilities, ranging from lighting design to finished lenses, meet the necessary requirements and are highly precise: We combine our interdisciplinary competences in lens and component design, high-tech tool and mold making, process development for plastic replication,.We thus fulfill both quality and economic requirements with highly developed processes and a wealth of experience.
In precision injection molding manufacturing, injection molded optics present special challenges which require innovative methods to meet our customers’ demanding expectations. As today’s technical needs require ever increasing volumes of instant data transfer, the need for near-zero variation in molded optics in opto-electronic devices becomes apparent. Often times, the differentiator between a functional device and a reject is a handful of microns on a lens center location.
we have refined our polymer molding capabilities over the years – moving from integrated lenses to micro lens arrays, light pipes for military and medical applications and molded prisms for imaging. Specialized mold designs with replaceable optical mold inserts and carefully developed and controlled molding processes ensure the highest quality molded optics again and again.
Molded Optics QA
As part of the custom plastic molding process, quality control is paramount. The performance of our molded optical components is verified using custom-designed test fixtures together with our laser interferometer, laser scanning and profilometry equipment. Advanced vision machine systems are used to check for contaminants and other defects, often times in our Class 100,000 molding cleanroom. We tailor the inspection and handling of the molded optics to meet your specific requirements.
Precision injection molded plastic optics requires special knowledge and capability. Due to tight tolerances and often extreme mold processing conditions, the injection mold designs and fabrication techniques require special knowledge and skills. The injection molding equipment should have advanced control capability and care must be taken to ensure cleanliness. Plastics Optics Molding The molding process parameters (temperatures, pressures, and speeds) are unique to precision optics molding and these processing parameters are generally a closely guarded trade secret. GPT mold’s molding equipment also includes robotics, conveyors, custom degaters, thermolators, vacuum loaders, and dryers.
Recent examples of lenses molded at GPT mold includes: freeform lenses for LED lighting, precision laser collimating lenses, CMOS imaging lenses for robotics and medical devices, eyepiece optics, integrating tunnels, TIR lenses for LED illumination, freeform prisms, fresnels, and a variety of lens arrays. The engineers at GPT mold Optics are experienced in when and how to take advantage of molded plastic optics.
