Mikami Co., Ltd.

Our strengths include world-class parts processing technology with lathing and thin film processing.

Our main business is parts processing by lathing. The work size can be between diameter 1 to diameter 120 for turning, and 500 × 380 × 300 for machining center processing. Our machining technology creates a mirror surface of less than 0.8 s, which eliminates the need for grinding as post-processing. Thin film processing is a necessary process for sensors, and usually refers to welding thin film to the main unit. Our method handles it as a machining process, involving cutting thin films of less than 0.1 mm. We have done business directly with customers in China, and we participate in exhibitions in Japan, the EU, and other regions every year.

[Company strength]
Our own network of partner companies makes it possible to apply thermal treatment, surface treatment, polishing, welding, and sheet metal working to products before delivery to the customer. Our thin film processing was adopted in a current project involving production of approximately 8,000 articles per month. The maximum production size is 12,000 pieces (five-year contract), and there have been no product rejections due to film thickness during this contract period. The lot size can be anywhere between a single article to mass production (maximum lot size in mass production is 30,000 pieces). 

[Business description]
We provide precision part machining for hydraulic mechanisms, and devices related to the optical, medical, sensor, and measurement fields. We process various materials, including SUS, iron, brass, and castings. The work size can be between diameter 1 and diameter 120 for turning, and 500 × 380 × 300 for MC processing. We develop and manufacture fast-blow fuses, and provide assembly services on an OEM basis.

[Strength of products/technologies]
Our thin film processed parts are adopted for pickup sensors such as sensors that measure gear rotation. The tips of such parts are usually 0.3 mm thick at best, but we can make them as thin as 0.1 mm (iron, aluminum, brass). We also possess technology for inside mirror-surface machining without polishing, which has been adopted for gas detection device parts. The manufacturing process was reduced to the minimum because of the mirror surface (0.8 s) created through our machining. It would not have been possible for us to make prototype fuses if we were not a machining manufacturer. (Other manufacturers do not make prototype fuses as single articles, because it normally requires a die beforehand.) 

[Representative's message]
Our company has been doing business directly with manufacturers in China since 2009. We also participate in exhibitions in Japan, the EU, and other regions every year, which has resulted in a gradual increase in the number of customers. Metal machining and assembly operations are our top sources of revenue, and mostly involve industrial devices, construction machinery valves, and mechanism parts for sensors. We plan to develop a compact fast-blow fuse for the field of semiconductor protection fast-blow fuses. We will offer this product as a protection device for industrial and PV power control and servo motor power sources to seek out new business opportunities. 

[Company structure for market development/overseas expansion]
We have English-speaking staff in our company who can communicate with overseas manufacturers by phone or email. We share new quotations among the related departments, and both the production and QA departments work together if they contain difficult processes. We also have an international exchange program with universities in Japan, and actively recruit overseas trainees. 

[Market share/Ranking]
Our fuses have a 0.1% share of the market.
