We will introduce an example of a large casing frame produced by Mitsuya Co., Ltd.
This product is manufactured as the interior frame of the "large insulated housing frame." The large insulated housing frame is divided into three sections, and this product is also divided into three parts to fit inside it. This product is essentially a sheet metal fabrication made by welding together processed plates shaped like angles. The outer surface has mounting holes for securing it to the large insulated housing frame, and the inner surface has tapped holes for attaching various functional cover components, which are processed before welding. Additionally, to fit inside the large insulated housing frame, the overall dimensional accuracy and distortion (diagonal dimensions) are strictly controlled, and various reinforcements and ribs were added during the welding assembly to ensure the accuracy of the holes and taps. When combined and fixed with the outer frame, there may be slight differences in precision, such as mounting holes aligning properly or being off by 1-2 mm, due to each of the three units being manufactured by different workers. However, by slightly modifying the areas where the outer large insulated housing frame interferes, all three units were able to be assembled together successfully.

basic information
There were very strict delivery requirements regarding the difficulty of production at Mitsuya Corporation, and there were concerns about whether the products could be loaded onto a truck for shipment from the Mitsuya factory during the production process. The size of each unit is quite large, measuring 1900mm in width, 2800mm in length, and 2600mm in height, with three units in total. We have a 4-ton truck with a box-type wing, but due to height restrictions, we arranged for a 10-ton flatbed truck without a box-type wing from a transportation company. By having the transportation company observe the products multiple times during production, we were able to plan the loading order onto the truck, as well as how to protect the products from rain and other elements during transport by installing protective sheets, ensuring that we could successfully ship everything in one truck.
