Marusan Electronics Co., Ltd.

Our company is an integrated manufacturer of heat sinks and other heat dissipation solutions.

Our knowledge on heat sink allows us to suggest the most beneficial heat dissipation solutions for the thermal problem in electronic devices. We also propose heat-diffusion solutions utilizing recent trends such as heat pipes. The quality of our products are guaranteed to meet your requirements. We introduced a new production management system last year and have significantly reduced our production time as a result. Several examples of our product applications include heat dissipation for optical extension wireless devices used in mobile-phone base stations, heat dissipation for power conditioners in solar power generation systems, cooling of controllers in machine tools, and cooling of semiconductor fabrication equipment.

[Company strength]
We specialize in manufacturing heat sinks for thermal dissipation in electronic devices. We deal not only with ordinary heat sinks but also our unique heat dissipation technology. We have also filed for many patents. We introduced a new production management system last year to utilize our 50years of quality control experience and have managed to reduce our delivery time significantly.
“Three strengths of our company”
Development: Conventional and well known heat sinks are adapted to meet the needs of our customers.
Production: The quality of our products is guaranteed to meet the customer specifications.
Distribution: Our new production management system has allowed us to significantly reduce our delivery time.

[Business description]
Our company was established 54 years ago and shifted from trading to manufacturing more than a quarter of a century ago. We are a heat sink (radiator) specialist company and make beneficial proposals to our customers, through design, prototypes and mass production. Our corporate philosophy is to “Provide (develop, produce and distribute) high-quality, high-efficiency parts to contribute to the development and improvement of any industry including the electronic industry”.


[Strength of products/technologies]
Heat is invisible in electronic devices and is a problem that constantly challenges the industry. We are tackling this problem head on to provide the most beneficial solutions. Moreover, we can provide heat diffusion solutions using recent trends such as heat pipes. (Product catalogues and drawings can be downloaded from our “List of products and technologies” shown below.) 

[Representative's message]
In recent years, our sales have rapidly expanded only in limited industries, however the domestic Japanese market is decreasing. Therefore we are driving sales channels (customer expansion) across our whole company to avoid the risk of overconcentration. We are steadily improving our business model to achieve an extremely short delivery time and launch new value-added products and high-mix low-volume production. For example, we are introducing further modern quality improvement programs in our overseas expansion to accomplish our desired sales channel expansion.  

[Company structure for market development/overseas expansion]
We are exploring new sales channels for developing new customers. We have established a Direct Sales Department to develop new customer and investigate the domestic Japanese market. To aid this, we actively participate in many product exhibitions. We are exploring the use of subcontractors in our overseas expansion to enhance our competitiveness. We are also examining the possibility of creating supply chains to the overseas plants of our domestic users.
