Sawane Spring Co., Ltd.

We are a spring and coil manufacturer that serves various fields, including automobiles and medicine. 

We are a spring and coil manufacturer established in 1966. Our company supplies products in a wide range of fields, with a focus on automobiles and electric appliances. Our customers are located both in Japan and overseas, and our domestic Japanese customers include major auto part manufacturers. Our overseas customers include medical institutions and universities in Europe, the US, and Asia. We have a joint venture with FAW Automotive in Wuxi, China as an overseas site. Our extensive technology allows us to manufacture irregularly shaped coils and springs even in small quantities, from a single piece, and deliver them in a very short time on request. This has fueled the growth of our company. Our subsidiary Samimi controls and operates the Stock Spring e-commerce site, where customers can easily place orders for springs online. This catalogue lists more than 5,000 springs at all times. 


Sales Pitch

Delivering small-lot products from as few as one piece, faster than anyone in the world
Our reason for existence is to be the fastest factory in the world
Our company produces springs in small lots, and delivers them swiftly through an original production/sales system. Small-lot orders of 20 pieces or less will be shipped on the next business day.
We specialize in winding things that are long and thin.
We are good at long coiling techniques and have wound an extended coil of 17 m (maximum).
Message for overseas companies
Development of special coils for catheters and endoscopes (in progress)
Rotation and torque transmission are improved by winding a wire with a diameter of 20 microns to 0.1 mm in multiple strips (up to 12) and multiple layers (2 layers, 3 layers, 4 layers, etc.).
Platinum and tungsten materials can be wound
Platinum and tungsten, recently used in medical components, can also be used for winding.
Preparing for ISO13485 certification
We plan to acquire ISO13485, a quality management system certification for medical equipment in spring 2020.

Other presentation

[Company strength]
We previously focused on mass production for auto part manufacturers, but we currently concentrate on receiving orders for small lots and sport products. We are promoting small lot production because each worker is involved in multiple manufacturing processes, and becomes a skilled worker. Trial and error with the finished goods in mind inspires employees with the excitement of Monozukuri craftsmanship. We actively accept orders for time-consuming irregularly shaped works, small lot production including single-article springs, and ultra-quick deliveries. We also offer more than 5,000 types of springs via the Internet through our Stock Spring website. We do business with more than 18,000 companies, including online catalog orders. 

[Business description]
Our company is a medium-scale spring manufacturer. We are committed to stable production of high-quality products, and to sharing our problem-solving process with our customers. Our lines of business include manufacturing prototype and mass-produced springs for various industries such as automobiles and electric appliances. We also manufacture small-lot springs for our “Stock Spring” catalogue order sales, which revolutionized thinking in the industry when we launched it in 1987. We established a joint venture in China in 1993, which was earlier than other Japanese spring manufacturers, and started production for the Chinese market. We have introduced original quality, production, and sales control systems for all these products. Our goal is to be a spring manufacturer that pleases customers. 

Spring and related product manufacturing and sales

[Strength of products/technologies]
We try to deliver products in the shortest time possible for both online catalog orders and small lot made-to-order items. Our goal is to become the fastest factory in the world. We also actively participate in trade shows, and take on difficult manufacturing methods that other companies would rather avoid. Our Micro Coil for medical research (a cerebral blood vessel clip for animal experiments) was developed as a result. We decided to initiate this project to satisfy customer needs, and productized a coil with a 0.16-mm inner diameter after trial and error. We now sell this product to many research institutions in Japan, the US, Germany, and other countries. 

[Representative's message]
Our company is managed under a philosophy of maintaining an optimal size, and making the company last permanently, because we are oriented toward protecting our employees. We want our employees to cherish the gift of life by realizing happiness and sufficient time through our management. We have been holding round-table conferences attended by all our employees for over 20 years, where we share the company’s vision of what we are doing, where we are going, and so on. We also want to take on new challenges in new technologies and new fields as a means to cultivate new sales channels. 

[Company structure for market development/overseas expansion]
Five sales representatives visit customers to cultivate domestic Japanese sales channels, and contact them individually by phone, fax, and email. We make use of trade shows in Japan, direct mail, and our website to meet potential customers. We jointly established an engine spring manufacturing company with FAW Automotive in Wuxi, China in 1993 for overseas expansion. Our products are also exported directly from Japan to cultivate overseas markets. We have one dedicated overseas sales representative (a Japanese employee who speaks English and Chinese) who uses the Internet for sales activities.

[Market share/Ranking]
Our company handles a wide variety of products despite our mid-scale size, from ultra-small articles to thick coils. Our Stock Spring website also offers an extensive lineup of springs on the Internet.
