High-precision coating technology and web handling technology have realized high-definition (several mm level) continuous transfer. We help our customers manufacture high value-added and differentiated products.
1.The transparent film is fed out from the feeding shaft and coated with UV curable resin.
2.The film is pressed through the nip roll onto a roll-shaped mold called a mold roll to transfer the shape of the mold roll.
3.The resin is hardened by UV irradiation, and the process from mold release to winding is performed in a continuous process and create a molded product.
Custom support is available for the requests for wider width, higher speed, protective film bonding, resin mold support, etc.
A transparent film is attached to the feeding shaft, and it is continuously fed at the surface transfer part. UV transfer the surface. After transfer, the film is inverted, the back and surface are UV-transferred by the back-surface transfer part, the front and back surfaces are aligned, and the film is wound by the winding shaft.
The alignment mark is transferred to the edge of the pattern area when UV transferring the front and back surfaces. The alignment marks on the front and back sides are taken with an alignment camera installed after the back-side transfer, and the relative position of the back side with respect to the front side is detected from the captured image and the position is corrected to the target position.
By using a transparent glass roll and arranging a UV lamp inside the roll, UV transfer to an opaque substrate has been achieved.
It can be used as a mold roll by wrapping a transparent film mold around a glass roll.
For intermittent coating, only the stamper attached to the roll can be coated by linking the stamper position and coating timing.
Our test equipment has a lineup of 120 mm, 400 mm, and 200 mm for double-sided transfer. We will provide tests according to your specifications.
