How to avoid chromatic aberration with colored LED plastic diffuser - PMMA diffuser

Do you think we only doLEDPC diffusers? Wrong, the diffuser used by our LED, in addition to PC material, we also make PMMA.

And all our PMMA diffusers can be colored according to customer requirements, but in the production process, how can we avoid the color difference of PMMA diffusers?

First of all, look at the temperature of the machine. If the temperature is 260°C, the residence time of the barrel should not exceed 10 minutes at most, and if the temperature is 270°C, the residence time should not exceed 8 minutes.  

Secondly, the die should be thoroughly cleaned after heating, and the accumulated dead material and impurities should be cleaned up to avoid the miscellaneous color mixing on the product.

Finally, the hopper and barrel of PMMA should pay special attention to its cleanliness. If there are other materials in the barrel, first clean the barrel (the cleaning material can be recycled PMMA). When there are PVC, POM in the barrel When waiting for materials, it should be noted that the barrel should be cleaned with PS and other materials first, and then cleaned with recycled materials, rather than directly cleaned with PMMA recycled materials.
