3800mm die
Die coater used in fields such as lithium ion batteries, films, and liquid crystals.
Strict processing accuracy is required to achieve a uniform film thickness used in the coating process.
We can handle various shapes and high precision with accumulated know-how.

High­precision die coater that enables uniform and uniform coating, which is the most important of thin film manufacturing technology for liquid crystals and films.

We have accumulated a variety of materials, shapes and precisions in the production of this die coater.

We can manufacture die coaters that realize high­precision and high­quality coating by incorporating our original processing know­how,


Die that realizes high­precision and high­quality coating
High­precision die for coating requiring a coating film deviation value of 2­5%.
In order to achieve high­quality application, high accuracy is required for geometrical and dimensional tolerances.
Processing accuracy

An ultra­high­precision die that can be realized by concentrating crystal optics technology.This is the reasons why it is trusted to quantify and guarantee accuracy.
