Company information
◆◆◆ We have obtained permission to manufacture medical devices. ◆◆◆ ■ Based on the idea that "the cost and quality of a product are determined at the design stage," we are involved in "monozukuri" (manufacturing) from the design planning phase. ■ Our company policy is to "deliver the necessary products in the required quantities to the specified location with the designated quality based on a single invoice from the customer." ■ At our headquarters/factory in Yonezawa, we conduct product development (design) and prototype (reliability evaluation), and after demonstrating the quality as a product, we transfer to mass production at our partner factory in China (we have been operating in China since 1993). ■ The partner factory in China operates under the same equipment, management, and systems as Sosei Electronics, using Japanese management methods. ■ Regarding the delivery of finished products, we deliver to the designated warehouses and factories of customers both domestically and internationally (Japan, Hong Kong, China, etc.).
