Miyoshi Seisakusyo Co., Ltd.

We continue to take on the challenge of innovation in resin and metal resin processing and metal working.

Our company has been extending its business since our establishment in 1952, with a focus on plastic part molding and forming as well as metal working. Our processing technology, production system, and quality assurance system are the source of our company’s signature quality, which we established by developing a large number of products. We are experienced in manufacturing various molded parts by injection molding for uses in lighting, electronics, printing, and other industrial applications. We manufacture products from a wide range of thermoplastic resins, such as PP, ABS, and PAR. We propose applications of our products for medical equipment and precision equipment. Several years ago we began to manufacture and sell original products for high-added-value fields not limited to plastic materials.


Other presentation

[Company strength]
Our advantages are the processing technology and quality assurance system that we have been employing to produce plastics related products for major companies since our establishment. We also apply this technology to manufacture and sell new original products. Our goal is to develop as a manufacturer capable of providing better products faster at a lower cost. We also think that we want to contribute to our local area as a company born in Muroran, Hokkaido.

[Business description]
Our company has been inheriting the spirit of Monozukuri craftsmanship since our establishment in 1952. We have done this by continuing to take on the challenge of innovation based on our plastic forming technology and production system. People now attach importance to made-in-Japan products and are looking for safety and security. We provide superior products that meet customer needs at lower prices from a global point of view. We plan, develop, manufacture, and sell lunch boxes with refrigerants and other-in-house products under an integrated system so as to be a company capable of quickly satisfying market demands.

Plastic forming

[Strength of products/technologies]
Our company has acquired utility model registrations and patents. We can manufacture and sell merchandise with greater technical strong points than existing products, and products that are not available from other manufacturers. We think these products and technologies are our advantages. We will continue our efforts to develop products with made-in-Japan quality that further satisfy customers in various settings.

[Representative's message]
Our company has continued to engage in processing from plastic part molding and forming to product assembly ever since its establishment. At the same time we have proceeded with building up our production and quality management systems while achieving various technical innovations. This is why we are highly appreciated among our customers. We have inherited the source of Monozukuri craftsmanship, which has been cultivated for many years, and develop products from the viewpoint of consumers to enrich their daily lives. We are transforming ourselves into a proposal-type manufacturer committed to providing safe and secure products. All of our staff will continue advancing their efforts without sticking to plastic materials to meet the leading needs of the age. This is based on our motto of lower prices and higher quality, which we have maintained since our foundation.

[Company structure for market development/overseas expansion]
We are now actively participating in exhibitions and trade fairs held by the government, financial institutions, and chambers of commerce and industry. Our goal is to strengthen our system of proposing applications of our products. At the same time we will appropriately ascertain market needs and work out a medium-term plan for future company development. The manufacturing and sales divisions will work together to further improve our corporate power.

[Market share/Ranking]
