Product information:

Optical injection molding techniques is a cost-effective way to produce plastic lens with high precision. It is suitable for making large quantity of plastic lens with spherical, aspheric and free-form surfaces. Injection molding can reproduce optics with a high degree of repeatability and accuracy. Mainly because of the precision built into the molds when they are fabricated and the precision of the mold process.

There are three major impacts of high precision injection molding: the injection molding machine, the molds and the press process. The quality of molds would determine the quality of final part directly. The molds are built to the negative of the part. That is, if you need convex surface, the mold would be concave. The molds are made of alloy, and fabricated with high precision lathe. Multiple parts can be pressed at the same time with multi holes on the mold. They are not necessarily to be the same design; different model of lens can be built in different holes on the same mold and manufactured at the same time to save the molds cost, while reducing the production speed of each model of parts.

Prototyping is necessary before batch production. The molds will be designed and manufactured based on the optical requirements. They might be modified to ensure the final parts can meet the requirement of customer. In batch production, there will be first article inspection as well as in-production inspection during the manufacturing process. And the last part manufactured will be saved for future inspection.
