During the mass production process of optical components, plastic injected lens product is often the most suitable choice. Unit price of plastic pieces appears to be much lower than optical glass. First step in the process of producing plastic components, the mold realization. If there is not much differences between PC and PMMA processing, molding allow a very high fidelity for complex shapes reproduction. Such as aspheric lenses.injected lens mold

Mold for plastic injection

This molding process is called molding-injection process and fit for the realization of any lens shape. This machine is composed of molding die that ensure a similar volume for all lenses produced, and a great reproductability.

Are you looking at reliable and cheap solution for the realization of your plastic optical projects? Sinoptix is now offering the realization of prototypes for your plastic optical components. Prototypes can be made out of different plastics materials such as PMMA, Zeonex, Macrolon, PC. Bellow, our range of optical plastic technical solutions for your prototypes:

Technology Details Advantages Inconvenients Usage
Injection Temporary fixtures -Part of the prototype development costs will be deducted from mass production mold costs. -only interesting if mass production injection is expected after prototyping -Longer to be set up – Draft angle to be expected Design almost validated Pre-production series and mass production
CNC machining Cutting, polishing, centering -Lower cost for simple shape products -Require several processes and equipment settings -Not appropriate for small quantities Complex shapes, Prototype validation for sketchy optical parts
Diamond turning machining lathe of precision -Great accuracy -No other polishing process needed -Less shapes available than CNC turning Aspherical and free form optics
3D printing Material added by microdrip -Low cost -Aspect Optical lightning
