Aizu Koujou Co., Ltd.

We have an original casting method, and manufacture precision casting parts. 

We started business as a foundry in 1975. We have since promoted technology development and continued research and development, and have established our original casting method called “H process” (horizontal stack mold casting method). We conduct all processes of product manufacturing in house, and perform strict product management, cost reduction, and the reduction of delivery period. We thus became able to sell high-precision high-value added products. We employed the “H process” (horizontal stack mold casting method), and realized thin-wall high-precision casting products which are impossible with conventional casting methods. We thus realized light-weight machining-less casting products, and also the reduction of total cost.

[Company strength]
We employed the “H process” (horizontal stack mold casting method), and realized thin-wall high-precision casting products which are impossible with conventional casting methods. We thus realized light-weight machining-less casting products, and also a reduction in total cost. We also integrally cast a product which is conventionally manufactured by welding multiple pressed parts together. We have thus realized high strength and cost reduction. We also have facilities for in-house integrated production from mold manufacturing to casting, heat treatment and machining. We thus established a system for providing products which meet customer needs in a very short delivery period while assuring quality. 
H process is a method in which multiple molds for making products are stacked, and multiple high-precision casting products are manufactured through a one-time molten iron pouring operation. It has the following advantages: 
Reducing costs, improving efficiency, improving dimensional accuracy, reducing weight dispersion, having high heat-retaining property thereby to prevent rapid cooling and obtain homogeneous material, reducing defects, reducing finishing work, and simplified operations. 


[Business description]
We started business as a foundry in 1975. We have since promoted technology development and continued research and development, and have established our original casting method called the “H process” (horizontal stack mold casting method). We conduct all processes of product manufacturing in house, and perform strict product management, cost reduction, and shortening of the delivery period. We thus became able to sell high-precision high-value added products, and differentiated ourselves from our competitors. 


[Industry]
Precision casting parts manufacturing 


[Representative's message]
We have manufactured products by our original method, and realized differentiation from competitors. The iron casting industry of today, however, is not in an environment where we can compete only in quality. We face severe circumstances due to low demand resulting from newly developed materials and the inflow of low-price products from China, etc. Competition with rivals all over the world began with the globalization of information, and competition with rivals in neighboring Asian countries has become especially fierce. We endeavor to realize overwhelmingly high-precision products which are impossible for our rivals. We will thus change the concept of casting, and create new demand. 


[Company structure for market development/overseas expansion]
We plan to branch out into foreign countries, and are conducting field surveys in India, etc. There are problems to be solved, such as the method for procuring raw materials and the establishment of a joint corporation with a local corporation. When solutions to these problems come into view, we will start a concrete investigation.
