Polycarbonate Profiles & LED Diffuser Covers
Custom polycarbonate profiles, most often LED diffuser and linear lighting covers. The same die normally runs clear, frosted and opal compounds, so one tooling investment covers the whole diffusion range for a fixture family.

Frequently asked
Can you match a specific light transmission and haze?
Tell us the target figures and the standard you measure against. We will confirm before tooling whether we can hold them in production rather than discovering it at first sample.
How do you keep long diffuser lengths straight?
Straightness on long profiles comes down to cooling and take-off control. Tell us the length and the tolerance your fixture assembly needs, and we will confirm what we can hold before you commit.
Can one die run clear, frosted and opal?
Normally yes — the section is the same, only the compound changes. That means one tooling cost covers your whole diffusion range.
