Optical films that require advanced processing technology and precision can also be precisely laminated.
At Sunny Sealing Co., Ltd., we perform advanced processing technology that produces high quality and high precision. We are also capable of processing all types of double-sided tape. We can create fine and intricate shapes according to your requirements, finishing tape widths as small as 0.3mm. Additionally, we ensure an appropriate release balance, taking into account the workability in your processes! By selecting molds, cutting tools, and jigs suitable for the conditions of the base material (thickness, hardness, adhesiveness, etc.), we achieve dimensional accuracy. While the guaranteed values may vary based on material, shape, size, and measurement points, we can achieve processing within 0.05mm. If the first trial does not meet the standard tolerance, our design, manufacturing, and quality control departments collaborate to repeatedly refine the specifications of the mold, target values, and other improvement measures to enhance accuracy. As a result, we have products that have achieved a precision of ±0.02mm at specific points. Furthermore, we accurately laminate optical materials (PET, PC, PMMA, polarizers, AG, AR, OCA, protective films, etc.) that have been cut and processed, without foreign substances, bubbles, or wrinkles. All processes are conducted in a cleanroom environment.

Company information
Our company leverages two strengths: "measurement and control technology" and "design and assembly technology for precision components," focusing on creating new value in manufacturing. As a pioneering company, we have long accumulated technology in the field of non-destructive inspection equipment for fruits and vegetables. We have expanded our focus from traditional measurements centered on the sugar content of fruits to inspecting for rot, cavities, and browning inside vegetables. By developing machines that can accurately inspect produce with variations in shape and quality even under harsh operating conditions, we significantly contribute to quality assurance of the internal quality of fruits and vegetables in Japanese agriculture. In the field of electronic component mounting, we have been engaged in OEM and ODM production of tape feeders and surface mount technology for over 30 years, featuring production facilities that can flexibly accommodate everything from small quantities of diverse products to mass production. Recently, leveraging our years of technology and experience, we developed an original splicing jig that realizes labor-saving in board mounting. This has already attracted inquiries from many companies and received high praise from the market.
