Imanishi Manufacturing Co., Ltd.

We provide small-lot production of precision casting products through the integration of digital technology and craftsmanship.

We manufacture and sell precision casting products, molds for castings, press molds for prototypes, and molds for plastic molding, mainly to the automotive industry. We can provide small-lot production of precision casting products without using molds thanks to the integration of digital technology (3D printers) and craftsmanship (uniquely established casting technology). Our methods have contributed to shorter delivery times and lower manufacturing costs compared to conventional processing. We have been accumulating knowledge and experience in materials processing since our foundation in 1921. We are capable of making products with shapes that are too complicated for a mold, as well as one-of-a-kind items. We also build production lines for automotive body assembly.


Other presentation

[Company strength]
Our company’s characteristic Monozukuri craftsmanship brings together our many years of accumulated mold-making and material technology, and digital technology with the latest computer-assisted processing. Our integrated system makes it possible for us to design and manufacture various molds and production equipment and make prototypes in a speedy fashion. We have been working hard on human resource development so that our employees can learn genuine Monozukuri craftsmanship and the feeling of happiness and pride in Monozukuri craftsmanship. We hope to pass this craftsmanship down to the next generation. 

[Business description]
Our company began as a manufacturer of wooden molds for castings in 1921. We have since expanded our business with a focus on 3D processing technology. Our main customers are auto makers in Japan and abroad. We design and manufacture various models made with 3D printers as well as precision casting. We offer press molds for prototypes, molds for plastic molding, welding jigs, and automation devices for automobile assembly.

General machine and tool manufacturing

[Strength of products/technologies]
Our customers rate us highly for various models and precision casting. This is because of our significantly shorter delivery time and lower manufacturing cost brought about by small-lot production that does not require molds. We have realized this with our casting technology using 3D printers and our unique rapid ceramic method. We are capable of making products with shapes that are too complicated for a mold as well as one-of-a-kind items. We have been using 3D printers for more than 20 years to integrate digital technology into our precision casting. We can make the best proposals for each customer with our experience in various fields and our accumulated technology.

[Representative's message]
Our unique technology integrates precision casting and 3D printer technology, which allows us to complete casting of complicated shapes within only a few days. This technology is the product of many years of accumulated craftsmanship that originated from our wooden mold manufacturing. We have been promoting a system to pass down our craftsmanship (by certifying employee’s technical achievements based on a skill standard map) and its environment. The goal is for our employees to be able to enhance their knowledge and skills. I also give lectures about new engineering to international students at universities and other institutions in order to actively communicate Japan’s highly sophisticated engineering technologies to other countries.

[Company structure for market development/overseas expansion]
We make the most of craftsmanship and digital technology to make various models and casting products in an integrated system from design to inspection. We possess two types of 3D printers: Stereolithography (SLA) and Laminated Object Manufacturing (LOM). We can make various models using the machine that best matches the customer’s application. We can also make prototypes made of various types of metal or resin materials using models as an original pattern, as well as articles with complicated shapes and one-of-a-kind items. All this can be done at a lower manufacturing cost and shorter delivery time. Please do not hesitate to contact us for inquiries about your difficult-to-solve applications.

[Market share/Ranking]
Impellers up to diameter 400 mm for hydroelectric power generation and various turbine products for the environment field. We have succeeded in reducing the manufacturing cost to half and delivery time to one-fifth compared to conventional metal block cutting or casting with molds. This is how we have been creating and expanding new markets.
