What we do
Optical customization of PMMA pellet for your application
We customize pellets for extrusion sheet and injection molding that apply our unique scattering technology.
More than 20 years of experience
We have more than 20 years of experience in pelletizing from cell-cast sheet. We can achieve with pellets an equivalent optical characteristics as cell-cast prototypes.

Pelletization Flow
Produce prototype material by cell-cast sheet. This way can achieve cost saving compares to making customized pellet from development stage.
Trim and shape the cell-cast sheet and check its optical performance. Repeat【step1】and【step2】until reaching the optimal formulation. This way also save cost compared to make injection mold at early stage of development.
After【step1】and【step2】process, we fix the formulation according to the test result, and move on for preparation of pelletization.
Adjust the formulation in necessary, and pelletization.
【MOQ】 25kg (for both trial and mass-production)
