When estimating new products in the manufacturing industry, I believe calculations are based on the "rate" (which may be referred to by various names such as "processing rate" or "charge," but here we will call it "rate") specific to each company. For newcomers who have just joined the company, there may be many who say, "In our company, the rate is set at ●● yen/minute, and we calculate estimates based on that, but I don't really understand how that number is determined." To establish the rate, one must know the manufacturing cost. The manufacturing cost varies depending on the processing method, the machinery used, setup time, processing time, and so on. In this document, I would like to examine, using specific numbers, how the integration of parts and the use of irregular materials affect manufacturing costs, taking the metal processing industry as an example.

【Lot】 100 to 10,000 【Processing】 Hot forging, machining 【Features】 This is a hot forged aluminum product. Hot forging has the following characteristics: 1. Material cost reduction During hot forging, the material deforms along the mold due to pressing, allowing for complex shapes to be processed all at once. As a result, the amount of material used is less compared to machining from square or round stock. 2. Processing cost reduction By using "hot forging" for rough shapes and "machining" for areas requiring higher precision, the total processing time can be reduced, which helps to lower processing costs. 3. Comparison with castings It has superior strength compared to castings. Additionally, issues such as internal voids that occur in castings do not arise. Aluminum is often used for lightweight components, and hot forging is a technology that can contribute to further performance improvements such as miniaturization and increased strength while keeping material and processing costs down. Due to its lightweight, high strength, excellent corrosion resistance, thermal conductivity, and machinability, the potential of hot forged aluminum products is vast.

We would like to introduce a case study of custom jig creation using a high-hardness resin 3D printer. There are many products with small lot sizes and a variety of types, and producing them through metal processing becomes expensive. Additionally, making them out of metal results in heavier products, leading to the challenge of wanting to reduce weight to improve work efficiency. Therefore, we created jigs using a 3D printer. As a result, the jigs have higher strength compared to general nylon and ABS resins, and they are significantly lighter than metal, which has improved work efficiency and made it possible to produce them at a low cost. [Case Overview] ■Challenges - High costs when produced through metal processing - Need to reduce weight to improve work efficiency due to heaviness of metal ■Results - Improved work efficiency - Possible to produce at a low cost For your reference: A video introducing our jig production by Ricoh https://www.ricoh.co.jp/3dp/case/matsui/ *For more details, please refer to the PDF document or feel free to contact us.
