ASAI CHUZO Co., Ltd.

Providing prototype development with short lead times, through direct application of 3D data

We have shortened the interval from 3D CAD data to model fabrication, with delivery in as little as one week. We can even handle one-off castings of less than 1kg. CAE analysis also lets us evaluate data to avoid any internal defects.

[Company strength]
We have continued, since our founding, to produce and supply castings in mixed types, small lots and short turnaround times to clients in many industries. We manufacture even castings of less than 1kg in lots as small as a single piece, in order to serve small and medium sized customers. This helps to support a variety of industries that continue to manufacture small-lot "Made in Japan" machinery. We typically take on 20 new item fabrication and prototype projects per month. Our extensive base of accumulated in-house expertise enables us to respond effectively to the diverse needs of our clients.

[Business description]
Our company has been involved in pig iron casting since 1946. We focus on rapid casting of prototypes, fusing age-old casting and cutting-edge IT technologies. Our objective is to be a company that will live on for a hundred years. We have implemented “imono-RP” manufacturing, in addition to traditional multi-type, small lot production, to deliver the shortest turnaround times for prototype casting. This begins with 3D CAD data, from which we create a wooden mold model, using an in-house machining center to accelerate the process. We then use a sand mold lamination printer to cast a prototype. The entire process can be completed in as little as one week.

Pig iron casting

[Strength of products/technologies]
An increasing number of companies are creating drawings using 3D data, but in many cases these data are not being effectively utilized in subsequent processes. The most widely used method is to employ 2D drawing as the intermediate stage between 3D data and model fabrication. The number of companies able to directly edit 3D data and create a model is limited. We simultaneously generate casting plan data in-house, further shortening the delivery period for model fabrication. We can also use such data to perform CAE analysis, such as inferring any internal defects in the casting.

[Representative's message]
Three-dimensional printing using photo-curable resin was first attempted, without success, more than ten years ago. Now, we feel that the time has finally come for 3D data to be effectively utilized. We believe that the introduction of the epochal 3D sand mold lamination printer has opened up unlimited possibilities for the future of casting. The era of “what can be made?” has passed; now the question is, “how can it be utilized?” We want to be one of the companies that can present the answers and disseminate information to a variety of casting users.

[Company structure for market development/overseas expansion]
Castings made using imono-RP technology are largely prototype products, giving rise to concerns over leakage of confidential corporate information. We have taken steps at our company to prevent the leakage of such information. This includes strengthening the security of our Internet environment, exercising control over visitors, eliminating Windows XP PCs and other measures. Two dedicated staff trained in 3D CAD have also been assigned to support the development of prototypes with a short turnaround time. We have no current plans for expansion overseas. It would, however, be possible for us to supply overseas locations for prototype development through the use of timely transportation such as international express delivery services.
