Our other lines of business lines include manufacturing and selling motorcycle engine parts, medical equipment parts, and gas equipment parts for customers including Murakami, Mitsubishi Heavy Industries, and Mikuni. We take pride in our technological strengths. We have developed various technologies such as vacuum PF die casting method with partial pressure for reducing blowholes inside casting.

[Company strength]
Our company has various kinds of certified workers on staff, including two employees who have acquired 1st grade certification as die casting workers, and five with 2nd grade certification. This is how we can assign specialists to each manufacturing process. Our die casting machines can manufacture 135- to 500-ton products with a mass of up to 2 kg in any lot size. We are trying to lower costs in our daily operations by promoting visualization and eliminating waste. 

[Business description]
Our company is an aluminum and zinc die casting manufacturer. We handle all die manufacturing processes including design, production, casting, finishing, processing, plating, and coating. Around 90% of our products are automotive rear-view mirror parts and motorcycle engine parts, and medical equipment and gas equipment parts account for the rest. We are committed to making the best products for our customers by making use of newly introduced equipment and technology. We also apply the extensive die casting know-how we have acquired in over 50 years of operations.

Aluminum and zinc die casting manufacturing

[Strength of products/technologies]
Our vacuum PF die casting method with partial pressure is a new technology that is currently under development. It is extremely effective for removing blowholes, which is a critical flaw in die casting. This method is also effective for flowlines (a defect involving wavy lines on the exterior) even when the condition is severe. It enables the use of T6 processing (normally impossible with die casting), which enhances hardness and thereby reduces weight. We possess independently developed machines and know-how that cannot be imitated by our competitors. 

[Representative's message]
Our company has commemorated its 50th anniversary as a die casting manufacturer. Everyone in our company is conscious of being a professional die casting worker backed by the extensive know-how we have acquired in our 50 years of operations. No one cuts corners, no matter what the product is. We aim to become your best partner by working closely with you, and helping you to manufacture advanced high-quality, low cost die casting products. We intend to further cultivate the domestic Japanese market while setting up new sales offices in Thailand, Vietnam, and Indonesia to enter these markets. 

[Company structure for market development/overseas expansion]
We actively participate in domestic Japanese exhibitions to cultivate sales channels. Most of the exhibitions we participate in are intended for automobile manufacturers, but we are gathering information on medical and electronic device-related exhibitions for future participation. Our website and brochures are available in both Japanese and English versions for the domestic Japanese and overseas markets. We also developed a Thai version of our brochure, and distributed 700 copies at a June business conference held in Bangkok. This indicates how focused we are on enhancing recognition of our company and its technologies. We are also actively making capital investments to reinforce our foundation at our HQ before moving on to overseas.

[Market share/Ranking]
Our automotive air conditioner die casting parts won an award for excellent quality from the customer.
