Dexerials' proud "roll-to-roll imprinting technology" is a technique that continuously forms fine structures ranging from several hundred nanometers to several hundred micrometers in size on films extending over hundreds of meters in length. Our company possesses two technologies for creating the master plates used to transfer fine structures onto film substrates: "lithography processing" and "precision machining." The surface of the cylindrical substrate is coated with a resin called resist, and after a laser light draws a pattern on the resist with a pre-calculated movement, a treatment called dry etching is applied, where plasma gas is used to form fine structures. Lithography processing can engrave intricate patterns on the master plate at the nanometer scale. The other method for creating the master plate is precision machining using machinery. In this process, a metallic cylindrical substrate is rotated while being cut with high-hardness bits (cutters) such as diamonds to form fine structures on the surface. *For more detailed information, please refer to the related links.

basic information
**The Amazing Machining Precision of Precision Machining** In the production of master discs through precision machining, it is possible to form fine structures at a microscopic level, achieving high machining precision. The cylindrical master discs are made from metals such as stainless steel or iron, with a length of 1600mm, allowing for the transfer of fine structures over a large area in a single operation. An important aspect of precision machining is the control of the machining environment. If the indoor temperature rises by 1°C during processing, a metal piece that is 1600mm long will expand by approximately 20µm (0.02mm) due to thermal expansion. If the fine structure to be machined is on the order of a few micrometers, this change is significant and cannot be ignored. Additionally, frictional heat is generated in the areas being cut with the tool. To perform machining with high precision, a stable machining environment is essential. Our company rigorously controls numerous parameters that affect machining precision, such as room temperature and material temperature, in addition to fully automated unmanned machining, ensuring that the intended shapes are machined with high precision. *For more detailed information, please refer to the related links.
