Analysis And Solutions To Failures Of Optics

We all know the importance of optics to automotive lighting. When the molded reflector is failed to pass photometric regulation, what can we do? Of course, we have to study any possible causes and then give solutions accordingly.

Some Causes Which Closely Related To The Toolings,
Such As:

  • 01) Wrong photometric design.
  • 02) Unreasonable part design.
  • 03) Sand holes on the optical surface.
  • 04) Part warpage due to mold ejection system.
  • 05) Low machining accuracy on the optical surface.
  • 06) Deviation of bulb resting position.
  • 07) Poor metallization on the optical surface.
  • 08) Mis-operations such as damage or polish on the optical.
  • 09) ...

The Solutions Are:

  • 01) Re-simulate and Re-design the optics (which should be done in the design stage).
  • 02) Improve part design for uniformity (which should be done in the PFM stage).
  • 03) Check mold steel to ensure no sand holes, and check the hardness of steel.
  • 04) Re-design the ejectors away from the optical surface.
  • 05) CMM inspection and re-machine with accuracy ±0.01mm (or even higher accuracy).
  • 06) Check the bulb resting position and re-machine.
  • 07) Improve the quality of metalized surface.
  • 08) Descend the optical surface and re-machine.
  • 09) ...

In every project, Toolsong keeps the right attitude to improve the molds and molded parts to exceed customers’ expectations.
