Case of Imanishi Manufacturing Co.,Ltd. using ATOMm-4000

Imanishi Manufacturing Co., Ltd. is the company which offers new manufacturing by utilizing both traditional craftsmanship and digital technology to the world continuously

Imanishi Manufacturing Co.,Ltd.

Imanishi Manufacturing Co., Ltd. was established in 1921.Their management principle is to offer wholeheartedly the products and services which are highly appreciated by customers almost a century. Their original technology(Rapid Ceramic Molding Method) which is mixed with precision casting and 3D printing leads the fast producing technologies to the world.

We talked to Mr. Hirofumi Imanishi, CEO of Imanishi Manufacturing Co.,Ltd. and here is what he said

Q what is your strong point of your business?

We have been providing mainly automobile business since established in 1921. Nowadays, we are adopting the 3D printing and the lastest digital technology rather than craftmanship and producing the various metallic mold, producting equipment, and many casting models. We were one of the first companies which introduced CAD/CAM systems. By Rapid Prototyping (RP) technology, we can accept consultation of making any complex shape, from model to precise casting.

Q The sequence of 3D printer introduction

To correspond to customer requests(cost cutting and shorten delivery time) after CAD/CAM system were introduced, we developed the new precision casting technology(Rapid Ceramic Molding Method) with the 3D printer and our original casting method. This new method is able to produce the complicated shaped model in only several days by using a model of 3D printer as a pattern model.
With this technology, from various industry such as automobile parts, a sporting good and the medical field.
We were the first casting manufacturer which introduced Laminated Object Manufacturing(LOM) in 1996. 3D priter provides us the capability of checking the model before casting. Therefore, it became easier to confirm the custmer’s request and we can assure the short delivery time.

Q About producing with short delivery time and high quality.

There has to be the matured craftsman to make the small number of prototype models. But we developed the original casting method(Rapid Ceramic Molding Method).We succeeded in development of precision casting method without wooden form, metallic mold, and foundry core.This original method shorten the delivery time by one fourth and cut the cost by a half. This is extraordinary technology and very competitive in the market. With assuring short delivery time and high quality, we are demanded from the domestic and abroad various industrial world.

Q Why did you add our stereolithography system?

Even though we had 3D LOM systems already and had original method with them, we were looking for new systems because our systems had been aging. Around that time, 3D printer’s boom had started and many new machines had been released. After all consideration, we chose CMET’s stereolithography machine"ATOMm-4000", because of its work-size, price, and material(whether dieing easily or not). ATOMm-4000 is suitable for evaluation of assembly or functionality. Of course, there is no problem with burning out materials for molding.


Category Evaluation
Disappearance time About 1/6 of paper layered model. Processing is easily without the paper carbonized.
Workability Model becomes lightweight,improved workability of the ceramic coating operation.
Evaluation of model Good delicate shape reproducibility, such as edges and thin.(when it is honeycomb shaped)
Material cost Necessary resin material cost is equal or less than paper layered model.
Using situation Not only casting master but also sales sample for meeting with customer designer.

※The above is an example

Q How does Stereolithography contribute for your business ?

Layered modeling has no limit of shape but strength depend on the physical properties. And it is difficult to keep accuracy because model has layered step. There are some task left because material strength is required in industrial products. we try to progress to the final product by Rapid Ceramic Molding Method.We expand not only car and industrial products but also art, design, environmental energy and medical field.

Q After Stereolithography introduction,how is customer’s evaluation?

At first, we confused about modeling condition setting because it was quite different from the paper layered modeling, but now we are able to make models in a stable. We are very satisfied with model accuracy.
Since stereolithography introduction, we have increased new business partners

Q How do you evaluate of CMET?

We regarded made-in-Japan and after-service as important.ATOMm-4000 is the exact machine that we want, and both sales person and engineer have great care of service to us.
We are very satisfied with CMET.
and consequently, we will think about installation of more machines from CMET.

Q At the end, Could you please introduce your technology?

We will correspond widely, even automatic equipment, welding jig, press mold, mold for molding resin, mold for metal casting and casting model.
Please feel free to contact us anything.

Daisuke Ida

Daisuke Ida was born in Tottori, 1987. He started thinking to be engraver when he is 17 years old by the influence of his father. When he was taking the class of department of sculpture at The Tokyo University of the art, he searched 3D printing technology to improve the creating speed and quality and he met CMET which supports his work by making stereolithography model. After that, he is using both conventional and latest method to create his original model.

Following the concept of "trial and casting stuck to quality and delivery", medical simulator "monoroid" having a high reproducibility and stereolithography machine 365 days operation "D365", and medical training model "OPENER", more recently home and abroad in such "casting magnesium" have been attracting attention, not only in Japan, but also in the world market. Here is the story we heard from Daichi Watanabe, CEO of JMC Corporation.
