R＆D
As a specialized manufacturer of high-performance soluble polyimide, WINGO Technology conducts material development starting from proprietary monomer design. Leveraging collaborations with Okayama University and Shinshu University, we advance custom development for cutting-edge fields such as semiconductors, electronic components, and lithium-ion batteries.
Our Development Framework and Key Features
In-House Capability from Monomer Design to Polyimide Production
We offer fully integrated material design, starting from the design of monomers—the foundation of polyimide—to the manufacturing of polyimide resins. Based on our patented, in-house-developed formulations, we deliver materials optimized for performance.
Flexible and Efficient Development through a Cross-Functional Team Structure
Instead of dedicated development teams, we adopt a cross-functional structure where developers handle multiple projects concurrently. This approach enables a small team to flexibly and efficiently manage various developments while leveraging knowledge gained from each project.
Joint research with Okayama University and Shinshu University
We are also actively involved in industry-academia collaborations, conducting basic research and applied development in cooperation with Okayama University and Shinshu University. Joint research has enabled us to design more reliable materials and has led to the development of advanced technologies.
Development and manufacturing system based on ISO9001
We have acquired ISO9001 certification, the international standard for quality management systems, and have established a manufacturing and management system based on this standard. We are committed to both customer satisfaction and quality, even at the development stage, by taking firm steps to confirm the quality of the final product.
Development Flow
Please contact us first to discuss performance requirements and intended use.
We will interview you in detail about your technical requirements and conditions, and determine the direction to take.
We will make a prototype of the polyimide material to meet your requirements and confirm its performance.
We will recalibrate according to feedback and provide samples multiple times.
Based on the sample specifications, we will submit a quotation for commercialization.
After the product is determined, mass production and delivery are performed.

Features of our polyimide
New monomer design technology
We develop materials based on “new monomers” formulated by Wingo Technology's proprietary formulations, rather than conventional general-purpose monomers. This enables us to achieve properties and high performance that cannot be obtained with conventional products.
High customizability
Viscosity, curing conditions, insulating properties, flexibility, etc. can be finely tuned according to the customer's usage conditions and performance requirements. We can provide tailor-made solutions to meet your requirements.
Support for small-lot prototyping to mass production
Prototypes weighing up to 10 kg can be made using our own facilities. When mass production is required, we have established a stable supply system in cooperation with partner companies. We can flexibly handle small quantities and a wide variety of products.
