Expert group specializing in the creation of foamed plastic with a view to overseas expansion

We are engaged in the creation of foamed plastic. We possess abundant knowledge of cushioning and sound insulation/vibration-proof materials made of urethane foam. Through joint research with universities and public organizations, we have developed hybrid motion-resistant springs which combine vibration-proof springs and low-resistance urethane foam. We have also independently developed “cushions for electric piano keyboards (highly-functional)” with a soundproofing function, which have been adopted by leading musical instrument makers. In addition, we are developing new products and technologies, with a view to business overseas expansion in the near future.

Sales Pitch

We offer complete proposals covering from material selection according to the customer’s use and purpose to processing methods and mounting methods of produced parts.
Soundproofing techniques: We provide suitable materials according to the type of noise you want to shut off.
We make use of our company’s large database of soundproofing materials to offer the soundproofing measures our customers require.
We analyze the frequency, magnitude, and cause of noise for soundproofing and design optimal soundproof materials by combining sound absorption, sound isolation, and vibration suppression characteristics.
An example of this is laminating a sound insulation sheet from Company A with a high-frequency-band sound-absorbing material from Company B and a low-frequency-band sound-absorbing material from Company C to make up very high sound insulation performance.
We have started production of high-density butyl rubber with a high damping effect.
In February 2016 we installed a production system in our Indonesia plant for unvulcanized butyl rubber sheets with a specific gravity from 2.5 to 3.0. We import this plant’s products for a Japanese air-conditioner manufacturer as materials for soundproof covers for outdoor units (compressors) and damping materials for pipes.
Production capacity: 100 metric tons per month
Size of products: 1 to 5 mm in thickness, 400 mm in width, 20 m in length
They can be cut and punched into any shape and size.
We can procure materials from all Japanese foamed plastic manufacturers.
We are not an affiliate of any material manufacturer. This means we can freely procure materials according to customer needs under the most advantageous conditions, including performance, cost, and delivery time. We can also offer higher-performance products by combining materials from competing manufacturers.
Message for overseas companies
Soundproofing and vibration insulation techniques
Our company has a plant in Indonesia. We process foamed materials into various shapes with our advanced soundproofing and vibration insulation techniques. We offer highly efficient solutions for soundproofing and vibration insulation.
Business performance: Musical instruments, air conditioners, and construction machines

Other presentation

[Company strength]
We have accumulated knowledge of many types of foamed plastic materials since our establishment in 1960. Our strength lies in our design techniques for cushioning and sound insulation/vibration-proof materials, which is based on this knowledge. We continuously engage in development of new technologies and products while proactively conducting joint research with universities and public organizations. We have so far developed bed mattresses for medical and welfare use as well as hybrid motion-resistant springs which combine vibration-proof springs and low-resistance urethane foam.

[Business description]
By processing foamed plastics, mainly urethane foam, we develop components for air conditioners, musical instruments and automobiles that can be used as cushioning, soundproofing and thermal insulation materials. We design specifications in response to user requirements by selecting and proposing materials, shape and installation methods.

[Strength of products/technologies]
The special cushioning materials we have developed for keyboards have successfully reproduced a feel close to that of acoustic pianos for electric pianos which do not have action mechanisms. In addition, their outstanding noiseless functionality has been highly acclaimed and they have been adopted by leading musical instrument manufacturers. Our soundproof covers for air conditioners are not only of high quality compared to conventional products but are also as competitive as foreign products in terms of cost-effectiveness. As a result, they have been successfully adopted by leading manufacturers of home electronics appliances in Shizuoka Prefecture.

[Representative's message]
We have always challenged the development of new applications since our foundation in 1960. Our urethane chip foam production technology, which was the reason of our foundation, still dominates urethane foam recycling. In the diminishing domestic market, we are focusing on proactive sales activities based on proposals that utilize our technologies, while continuously engaging in development of new technologies, new products and new markets. We have also launched a business strategy with a view to business expansion abroad within a few years.

[Company structure for market development/overseas expansion]
Our Sales Department takes the initiative in new business expansion into major domestic companies. We utilize matching projects implemented by government agencies and chambers of commerce while proactively participating in exhibitions including the Japan International SME Exhibition hosted by the Organization for Small & Medium Enterprises and Regional Innovation, JAPAN. We are also steadily moving forward with preparations to engage in overseas expansion rapidly and with a top-down approach.
