This time, I will introduce the reasons for using various thicknesses of sheet metal to create lockers and the purpose of standardizing the plate thickness for making a single locker.
At Jinzhang Works, we primarily use a sheet metal thickness of 0.8 mm when making lockers for valuables. However, we differentiate the thickness based on the product: 1.0 mm for map cases and 1.6 mm for sports lockers. While using thicker sheets can increase strength, using excessively thick sheets can make the product heavier and less user-friendly. Additionally, the price of materials varies with thickness, which can lead to higher product costs. Therefore, at Jinzhang Works, when we receive an order from a customer, we inquire about the size and weight of the items to be stored, as well as the usage conditions, such as whether a person will be sitting on it. This allows us to select the appropriate sheet thickness to create a "durable" locker tailored to the intended use. In the past, we have used various sheet metals for a single locker, including 0.6 mm for reinforcements, 0.7 mm for inner boxes, and 3.2 mm for cams, in addition to the standard 0.8 mm.

basic information
At the time of design, we were purchasing cut sheets and using various thicknesses of sheets for a single locker, but a new problem arose when we started nesting in-house. This was the issue of poor yield, as previously introduced in the article on "Improving Productivity through Lot Optimization." If we were to mass-produce the same locker, the yield would improve, making it no longer a problem. However, the strength of Nihonbara Works lies in its integrated production system that allows for a wide variety of small-batch production. Therefore, it became necessary to design with the premise of individual production, leading us to change to lockers with standardized sheet thicknesses. After the change, we were able to nest reinforcement materials from the same 0.8 mm base sheet without purchasing a new 0.6 mm base sheet, which helped keep costs down by increasing the thickness of the sheet metal. In this way, by making changes even in areas that are not visible, we will continue to provide better products to our customers.
