Product Information

1. 94% light transmittance anti-yellowing liquid injection molding silicone optical lenses for indoor and outdoor LED lighting, material is Optical Liquid Silicone, hardness is 5/30/60/70/80/90 Shore A, mold type is LSR Injection Molding.

2. Silicone optical lenses made of super transparent and flame resistant optical liquid silicone raw materials.

3. LIM silicone lenses processed by ARBURG Liquid silicone rubber injection molding in Class 100,000 optical clean workshop.

4. Comparing to PC or PMMA, the transparency and dispersibility of the anti-yellowing silicone lenses are better.
5. Under harsh conditions, the color of silicone optical lenses is very stable even under temperature over 150℃。
6. With excellent processing properties, especially in LED lighting and optical lenses, the LIM silicone lens can achieve various complex and lightweight designs.
7. Anti-yellowing effect is perfect even after 3000 hours 85℃/ 85% Aging testing.
8. With a professional team, both the mold making team and LSR injection molding team, to assess design feasibility and trial production stability, also the successful experience to ensure the project to be launched successfully.

9. Surface finish of silicone optical lenses can achieve to a1.

10. LIM silicone lenses adapt to complex special shape and partial under-cut.

11. For anti-yellowing silicone lenses,we used TaiWan Union M7 series injection molding machine,high precision machines make our silicone optical lenses higher quality. 

12. We have 9 sets ARBURG Horizontal Liquid Injection Molding Machines, 3 Sets Vertical Liquid Injection Molding Machines, Class 100,000 Clean Production Workshop,Class 10,000 Full Inspection Room, 1 Set EVERFINE Light Distribution Performance Test System for LIM silicone lenses.

FAQ

  • 1

    What’s the advantage to choose liquid silicone to make optical lenses?

    Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical liquid silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable.

  • 2

    What’s the level of your clean production workshop?

    Currently, for Liquid Injection Molding, the workshop is Class 100,000, while for plastic, our factory has Class 10,000, or even Class 1,000 clean workshops.

  • 3

    Can you design the optical linear lenses?

    For now, we just do OEM designs. Our team is unable to do the product design.

  • 4

    What should I offer to custom silicone optical lens?

    Pls. offer us 3D drawing and performance requests.
