Business
About Chugai
Since its founding, Chugai has upheld the philosophy of “development and delivery,” planning, developing, and delivering products that users require in collaboration with manufacturers. Building on this philosophy, our business is driven by the following three core divisions:
- Sales Division, which proposes new business initiatives by identifying and responding to current market needs
- Manufacturing Division, which offers advanced development technologies and production capabilities in the field of acoustics
- Solution Division, which delivers optimized proposals for sound absorption and insulation, thermal management, and in-vehicle lighting through simulations
Alongside these three core divisions, we operate in partnership with our group companies, including:
- Fuji Polymer Industries Co.,Ltd., manufacturing silicone rubber products that support electronic components across a wide range of applications
- HAKKOSONIC Co.,Ltd., specializing in LED lighting products
- Epoch Molding Co., Ltd., producing EPP (expanded polypropylene) foam products
Products created under our robust quality assurance system continue to generate new value to meet the evolving needs of customers and the times across diverse fields—including the globally recognized Japanese automotive industry, electronics, information and communications, housing equipment, and logistics.
Sales Division
Since its founding in 1948, Chugai’s Sales Division has built a diverse network of suppliers through transactions with customers across a wide range of industries. Building on this track record, we have established sales channels throughout Japan. Through these channels, we accurately and promptly capture social and market trends as well as consumer needs, and provide manufacturers with feedback on the ever‑changing market conditions, supporting the delivery of solutions that meet our customers’ requirements.

Soundproofing Parts
Soundproofing materials include sound‑absorbing materials that absorb sound and sound‑insulating materials that block sound. Depending on the type of noise—such as engine noise, motor noise, and road noise—appropriate materials are selected and applied in the most effective locations.
Thermal‑Insulating and Sound‑Absorbing Parts
These parts are designed as thermal countermeasure solutions with high heat‑shielding performance and can be installed in high‑temperature areas such as around engines, exhaust pipes, and mufflers. They also feature sound‑absorbing performance.
Foam Parts
Due to their ultra‑lightweight nature and excellent shock‑absorbing properties, these parts are used in bumper absorbers for pedestrian protection, tibia pads for occupant lower‑leg protection, and seat core materials. Their resilience also makes them suitable for use in tool boxes.
Thermal Management Products
These products address thermal issues associated with the miniaturization and enhanced functionality of electronic equipment by utilizing a wide range of solutions, including heat conduction, heat diffusion, and heat radiation.
Lighting Products
These products provide functional lighting using clear LED illumination, including lighting that vividly enhances vehicle interiors.
Electrical and Electronic Components
We supply a wide range of electrical and electronic components, including control ICs used in electronic equipment, mobile‑related parts, LED‑applied products, industrial‑equipment‑related products such as those used in elevators, and power‑related products.
Chemical Products
We handle a wide variety of chemical products used across numerous industries, including automotive parts, electronic equipment, and aircraft.
Others
We also handle products across various other categories to meet customer needs.
Manufacturing Division
Chugai’s Manufacturing Division is a soundproofing coordinator dedicated to the pursuit of sound and the proposal of comfortable environments. We collect direct and real-time information from the market through close relationships with users, and create products that meet market demands based on our “development and delivery” philosophy, under which we plan, develop, and deliver products in collaboration with manufacturers.
Research and Development
We research and evaluate the properties and formulations of various materials, and continuously work to develop new materials as well as improve and refine existing ones.
Design
We design products using 3D CAD and CAE analysis tools, incorporating customer needs, manufacturing requirements, and the design intent of our engineers.
Production Engineering
We design molds that enable the production of high-quality products, establish highly efficient and safe manufacturing processes, and deliver products to customers in a timely manner.
Quality Assurance
We are committed to improving product quality by being involved from the product development and design stages, maintaining our quality standards, and understanding customer needs.
Solution Division
Alongside our Manufacturing and Sales Divisions, Chugai has established a Solution Division to address a wide range of customer needs. The Solution Division supports customers in solving their technical challenges by leveraging practical insights gained through handling a diverse range of products, expertise in acoustics cultivated over many years, and simulations for thermal management and in-vehicle lighting.
Sound Solutions
Based on sound diagnostics, we propose solutions to achieve quieter environments by selecting appropriate soundproofing materials and placing them in the most effective locations. We are equipped with evaluation facilities and measurement equipment for sound analysis, establishing a solid framework for new product development.
Thermal Solutions
This service proposes optimal thermal management products and configurations using simulations to address customers’ heat-related issues and challenges. Thermal design support and various thermal measurements are also provided.
Lighting Solutions
Using optical simulations, we propose optimal configurations of optical components such as light guides and light source units.
