Production Process Flow

工程1Adhesive Blending
We have established a mechanism through automatic management via computer control and an operation display panel from compounding to stirring, whereby the mechanism does not proceed to the next step until each process has completed normally. This system reduces blending mistakes to zero.
We have introduced a state-of-the-art clean coating machine with a wide range of applications from thin film to thick coating. By employing a closed-type application, it is uniform and stable at the start and end of coating.
To stabilize the physical properties of the coated adhesive, it is aged for a certain period of time under strictly controlled conditions and atmospheres.
工程4Inspection of Physical Properties
We inspect physical properties of our products such as adhesive strength and peeling strength. A high evaluation in the market is based on good quality materials and strongly fixed coatings, as well as data detected from many test items.
工程5Semifinished Products
Automatically transported semifinished products are stored in a warehouse until they are finished. This contributes to an improvement in quality control as well as space saving and an increase in work efficiency.
Slitter processing in a clean room environment. We have realized a consistent production system in an airlocked, clean environment from clean coating to finishing.
Jumbo rolls (mill rolls) extending to 3000 m number of turns, which have been processed with adhesive in the coating process, are rewound the specified number of turns.
A cutting machine equipped with a high-functioning cutting tool for specialist adhesive tape reinforced in all parts. It can also handle wide tapes, and cuts semifinished products to the specified width. After cutting, the tape is transferred to the packing process after the final inspection.
Coating Process
The coating process consists of blending the coating adhesive, stirring, then coating, aging and finally inspecting. In particular, coating is carried out with a precision paint film coating in a very clean environment (work environment: class 10000, head part: class 1000). This technique is utilized to produce surface protection films and functional films, and, in particular, protective films for optical sheets and protective films for cars are employed by major manufacturers and are highly valued. Also, in another production line, we have realized 1-pass coat production from the traditional 2-pass production with the specification of rear mold release ⇒anchor coat⇒adhesive coat⇒winding. In the drying process, the floating method is employed. The drying efficiency has increased by 30% compared to the traditional method, leading to a speed-up in production.
Finishing Process
The finishing process consists of rewinding from the coated roll to the product, cutting to match the use and purpose, and packing the product. In the rewinding and slitter process, in addition to high-speed, precise winding control, the machine downtime is reduced due to a unique mechanism and control system, greatly increasing the operation rate.

Product Processing Techniques

To help increase the workability efficiency and rationalization for customers using our products,
we are striving to establish processing techniques so that our products can be used in a variety of forms.


Through layering and punch processing, waste is reduced, rationalization of tasks is possible,
and we aim to increase efficiency by integrating processing that spans multiple companies.
