General Comparison of Sheeting Method (Extrusion vs. Cell-Casting Method)
Here explains what is Cell-Casting method and its features, and advantages comparing to Extrusion method.
| Cell-Casting Method | Cast “Liquid MMA” directly into Cell-Mold. (Batch Process) Suitable for High-Mix/Low-Volume Production. |
|---|---|
| Extrusion Method | Put “PMMA Pellet” into the extruder and make it flat sheet. (Continuous Process) Suitable for Low-Mix/High-Volume Production. |
| Cell-Casting Method | Extrusion Method | |
|---|---|---|
| Advantage | No. Double Refraction (No birefringence). Suitable for optical sensor cover filter. High-Mix/Low-Volume. Color match and other customization. Higher Molecular Weight better chemical resistance | Shorter production lead-time and lower production cost because of continuous process. Easier to control thickness tolerance. Easy to make large size sheet. |
| Disadvantage | Longer production lead-time and higher production cost because of batch process. More difficult to control thickness tolerance. | Double Refraction (birefringence) in general. Not flexible in terms of customization. Low-Mix/High-Volume. |
