"As a BCP measure, develop new suppliers for nearly 100 parts." Even if I'm told that—there aren't enough man-hours, information, or manpower on-site. To increase suppliers, costs must be kept in check. The specifications of the drawings are inconsistent, and the processing methods vary... Who should I ask, from where, and how? In such a complex situation, Bandai proposed an approach to review the drawings and processing content from "a certain perspective." ➡ For more details, please check "Download the Catalog!"

• 3D Printer

We would like to introduce a case where we achieved a reduction in delivery time, initial costs, and processing costs through metal 3D printing. To solve the problem of wanting to produce complex-shaped parts quickly without the need to manufacture jigs that incur initial costs, 3D printing is ideal as it allows for processing without jigs and in a short period. Since 3D printers form shapes through "layering," the setup time and impact on processing time due to shape are minimal, and in this case, it can be processed at a lower cost compared to machining.

We would like to introduce a case where we received an urgent request from a client in Ehime Prefecture to manufacture 150 types of processed parts within three weeks. Our company held a strategy meeting with processing contractors. Since sheet metal processing was the most common, we first visited Company A, which specializes in press and laser processing. We divided the processing assignments while consulting with the person in charge. For the ASSY parts, which seemed challenging, we decided to request Company B from the Shimane Processing Network, known for saying, "Leave it to us for prototypes." Although there was a possibility of delays due to heavy snowfall, we managed to complete the project, and we received praise from the client, stating, "Despite the short delivery time, we are fully satisfied not only with the quality but also with the cost." **Summary** - The Shimane Processing Network has close relationships and is concentrated in neighboring areas, allowing us to respond to requests that may seem impossible at first glance. - Our strength lies in our ability to handle everything from single-item processing to ASSY processing through welding with a sense of speed. *For more details, please refer to the PDF document or feel free to contact us.*

In the past, there was an exchange with a processing company regarding sheet metal materials. This processing company delivers products made from blast furnace materials to customers, but there was a consideration for using electric furnace materials due to a certain opportunity. "Blast furnace" and "electric furnace" are terms that we often see in newspapers and other media lately, but I wasn't quite sure what the specific differences were, so I decided to look into it. First, the major difference between the two is the "refining method." Additionally, the "raw materials associated with the refining" are different.

Everyone, do you accurately understand the meaning of welding symbols? I believe that processing companies that actually perform welding understand them, but how well do sales representatives from technical trading companies like ours comprehend them? If a sales representative receives a drawing from a customer and can immediately say, "The key point of this weld is..." it would be very reassuring, wouldn't it? However, isn't it often the case that it just ends with, "They are welding..."? Depending on the material and application, is arc welding, TIG welding, or even fiber laser welding necessary? Isn't it common for it to end with something like, "Let's get a quote from that processing company for this type of welding"? *You can view the detailed content of the column through the related links.

What is lost when something becomes hard? It is toughness. Toughness is like the ductility that a material possesses. When hardness is increased, this ductility is compromised. What happens when toughness is compromised? Let’s take diamond, the hardest mineral in the world, as an example. While diamond has a very hard image, this is only effective against wear and scratches; it can easily shatter when subjected to impact, such as from a hammer. *For more details on the column, please refer to the related link.

During discussions with an automation equipment manufacturer, we caught wind of the information that "a certain component is experiencing early wear and requires countermeasures, but we are struggling to find improvement solutions." Here, we would like to introduce a case where we responded to the client's request for extending the lifespan of conveyor rollers within a limited budget. We recalled that during a project aimed at extending the lifespan of cutting tools, we had formed a metal coating with properties harder than the tool itself on the surface, and decided to proceed with surface treatment considerations. We consulted with Company A, a processing contractor renowned for its expertise in surface modification technology, and under the theme of "creating low-cost rollers specialized for wear resistance," both companies discussed the manufacturing process. Next, we explained the manufacturing process to the automation equipment manufacturer and moved on to prototype evaluation. As a result, a low-cost and high-performance product was completed. [Results were favorable] - By using inexpensive materials for the roller body and applying superalloy only to the surface, we achieved low cost and wear resistance. - Simultaneous grinding and finishing of the sprayed area and the bearing sections at both ends of the roller resulted in a high-performance product with minimized rotational runout. *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of a request for solving a difficult problem from an automation equipment manufacturer. We received an inquiry from an automation equipment manufacturer, with whom we have worked on many processed products, regarding a processed product to be used in a new development project for a leak testing device. The request was, "To ensure that the O-ring is securely held, the groove for the O-ring on the in-roller shaft needs to be sloped. Is this feasible?" We selected a processing company, explained the response details to the automation equipment manufacturer, and proceeded with prototype evaluation. Each iteration of the prototype increased the difficulty, but we finally resolved the challenging issue of air leakage on the third attempt by steepening the slope to 24 degrees. By meeting the customer's needs and facilitating cooperation between the automation equipment manufacturer and the processing company through our company, we were able to solve the problems faced by the client. [Challenge] We want to add a groove for inserting an O-ring to prevent air leakage in the in-roller section of a flanged shaft, but if the groove shape is straight, a phenomenon occurs where the O-ring is pulled by the pressed parts during repeated air leakage tests. *For more details, please refer to the PDF document or feel free to contact us.

During a visit to a car parts manufacturer we have been working with, we discovered a large quantity of used punches. A 200L drum was filled with used punches measuring Φ8×27mm. Upon inquiry, we learned that the quality of the punches currently being purchased is unstable, leading to variability in tool life and making it difficult to calculate replacement timing, which has caused confusion. We promptly introduced the designer of the punches and conveyed the situation on-site. Although the designer was at a loss, they explained a rough outline of a proposed solution based on their previous experience with custom machining, which led to the response, "Please go ahead with Bandai!" When we proposed an improvement plan using metal film coating to keep costs down, we received feedback that they had previously attempted this but experienced early breakage instead. From that information, we hypothesized that the heat generated during the coating process might be the cause and began to take measures. As a result, the previously unstable usage count of the punches increased to an average of 15,000 shots, achieving a stable lifespan that is approximately three times longer. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where an agricultural machinery manufacturer was perplexed by the request for "quality stability" and "stable supply" of the extremely rare part known as the handling body. From the sales know-how and information accumulated in our company, we caught wind that a processing company in Shikoku was manufacturing similar parts, and we approached that processing company for consultation. When we conveyed the current situation, we received advice that in order to enhance quality stability in mass production, dedicated jigs should be prepared. We communicated this to the agricultural machinery manufacturer and produced a prototype. We decided to implement automatic production using robots. Following the advice, we also manufactured dedicated jigs based on those specifications. Additionally, considering the transportation efficiency from Shikoku to our Shimane sales office, we created a "two-story transport rack." The prototype performed well, achieving an astonishing quality stability with a handling blade entry and exit amount of less than 0.02 mm. We successfully cleared the challenges of "quality stability" and "stable supply," and by redesigning the part and automating production, we also succeeded in reducing costs. *For more details, please refer to the PDF document or feel free to contact us.*

I have been regularly proposing custom processed products and new materials to the materials manager of our business partner. When I suggested A&D products as materials deemed necessary for the equipment, I learned that they were struggling with delivery issues related to their current overseas manufacturers and the responsiveness of their sales representatives, and they were uncertain about how to proceed with the next project. Before presenting a quotation to the customer, during discussions with A&D, it became clear that there were no delivery specifications or construction manuals. To avoid causing any difficulties for the design team, we created specifications and a construction manual while continuing our meetings with A&D. Everything was compiled into a single file and submitted to the design team, resulting in a smooth replacement. [Creation of Specifications and Construction Manual] - Specifications Content: Drawings of the constituent products, electrical connection diagrams - Operating Instructions for Constituent Products: Concise operating instructions summarizing key points - Construction Manual Content: Construction procedure manual using comic illustrations *For more details, please refer to the PDF document or feel free to contact us.

There are four main methods of heat treatment. The toughness we discussed last time is imparted by performing "tempering." It is often said "quenching and tempering," and it is common to perform these together to give steel surface hardness and toughness. Annealing and normalizing are not frequently used in the processing we mainly handle, but the photo of the handle shows that annealing was performed to soften the iron and bend it. The base part of the bend has undergone annealing. *For more detailed information, you can view it through the related links. Please feel free to contact us for more details.*
