We propose a variety of customized products.

"Cell-Cast sheeting method" and "CLAREX Technology Platform" make it possible to propose variety of optically valued products.

CLAREX Cell-Cast Sheeting Method

Introducing the Cell-Cast Sheeting Method and its features.

Advantages and disadvantages comparing to other sheeting method like Extrusion method can also be found.

Features of Optical Grade Cell-Cast Acrylic Sheet

There are mainly 2 methods of producing PMMA sheet which is Cell-Casting and Extrusion method. And CLAREX / Nitto Jushi Kogyo Co., Ltd. adopts Cell-Casting method.

Production Method of PMMA Sheet (Cell-Casting)

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 　　
  1. No. Double Refraction (No birefringence)
    - Suitable for optical sensor cover filter -
  2. High-Mix/Low-Volume
    - Color match and other customization -
  3. Higher Molecular Weight
    - better chemical resistance -
  1. Shorter production lead-time and lower production cost because of continuous process.
  2. Easier to control thickness tolerance.
  3. Easy to make large size sheet.
Disadvantage
  1. Longer production lead-time and higher production cost because of batch process.
  2. More difficult to control thickness tolerance.
  1. Double Refraction (birefringence) in general.
  2. Not flexible in terms of customization
    - Low-Mix/High-Volume -
    3. 　
  3. Lower Molecular Weight.
