General Comparison of Sheeting Method (Extrusion vs. Cell-Casting Method)<\/h2>\n\n\n\n

Here explains what is Cell-Casting method and its features, and advantages comparing to Extrusion method.<\/p>\n\n\n\n

Cell-Casting Method<\/th>Cast “Liquid MMA” directly into Cell-Mold. (Batch Process)
\u2003<\/span>Suitable for High-Mix\/Low-Volume Production.<\/td><\/tr>
Extrusion Method<\/th>Put “PMMA Pellet” into the extruder and make it flat sheet. (Continuous Process)
\u2003<\/span>Suitable for Low-Mix\/High-Volume Production.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
<\/th>Cell-Casting Method<\/th>Extrusion Method<\/th><\/tr><\/thead>
Advantage<\/td>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<\/td>		Shorter production lead-time and lower production cost because of continuous process.

Easier to control thickness tolerance.

Easy to make large size sheet.<\/td><\/tr>
Disadvantage<\/td>Longer production lead-time and higher production cost because of batch process.

More difficult to control thickness tolerance.<\/td>		Double Refraction (birefringence) in general.

Not flexible in terms of customization. Low-Mix\/High-Volume.<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div><\/div><\/div>\n\n\n\n
