In recent years, the demand for high-tensile materials has been increasing due to the need for lightweight components in automobiles and other applications. Compared to standard materials, high-tensile materials can achieve weight reduction while maintaining strength; however, their strength also leads to higher forming loads, making processing more difficult. This column provides detailed information about what high-tensile materials are, along with their advantages and disadvantages. *For more details, you can view the related links.

Machining by cutting allows for high precision finishing, but requires a certain amount of processing time. Compared to cutting, press processing is inferior in terms of precision, but it excels in production efficiency. If parts that were previously manufactured by cutting can be produced using press processing, significant cost reductions can be expected. *For more details on the column, please refer to the related links.

This is a technical proposal example for the production of sheet frames. The product in this case was initially designed with machining drawings and was planned to be manufactured through machining. The expected monthly production was 2,000 to 3,000 units, but there was a challenge that production through cutting processes would result in high costs. Therefore, we proposed a method transition from cutting to press processing through cold forging. This led to a 40% reduction in costs. [Case Overview] ■Challenge: High costs with cutting processes ■Effect: 40% cost reduction through method transition to press processing *For more details, please refer to the related links or feel free to contact us.

This is a case study of a technical proposal for sim ring manufacturing. Due to the customer's request to reduce procurement costs since product processing is outsourced, we received an inquiry about whether it was possible to maintain the same quality as fine blanking products while processing them with a press.

We solve the concerns of customers regarding press parts, such as "I want to reduce costs for functional parts that were traditionally made through cutting processes, but I don't know how." We will ask customers in detail about the specifications, applications, and assembly components of the parts, and while reconsidering the precision that customers truly need, we will provide optimal proposals. While the benefits may vary depending on the quantity lot, we will achieve cost reduction by transitioning from different manufacturing methods. Please feel free to contact us first. 【Features】 ■ Cost reduction through transitioning from different manufacturing methods such as cutting processes ■ The advantages of press processing can be utilized as the number of processed lots increases. ■ If there are concerns, we will conduct prototype testing with simple molds in anticipation of mass production and evaluate quality. *For more details, please refer to the related links or feel free to contact us.

We solve the concerns of the industrial equipment and robotics industry regarding press parts, as "a considerable number of gear and cam parts are needed, and we are considering the optimal manufacturing method." In the case of a lot of about 3,000 pieces, machining requires a significant amount of setup time, and this long lead time is also reflected in the cost. The more complex the shape, the longer it takes and the higher the cost. If using press processing with molds, once the mold is made, it is possible to efficiently produce parts with stable quality. Please feel free to contact us first. 【Features】 ■ Cost reduction through conversion from other methods such as machining ■ Advantages of press processing that arise from lots of over 3,000 pieces ■ Prototyping with simple molds considering mass production *For more details, please refer to the related links or feel free to contact us.

Kumagai Seiki Co., Ltd. solves the concerns regarding press parts, such as "We want to manufacture high-precision cam parts, but we would like to consider whether we can do it with press processing." Instead of manufacturing molds for mass production from the beginning, we conduct shape and function verification starting with prototype processing using simple molds. In the simple molds, the base die set uses common components, and we adopt a "nested" format that allows for the replacement of parts such as punches and dies according to the shape and size of the parts being manufactured. This allows us to keep costs down while conducting prototype pressing using molds. For those who want to verify the feasibility of production and shape confirmation through press processing, we first propose prototyping using simple molds. 【Features】 ■ Cost reduction through conversion from other processing methods such as cutting ■ Cost advantages of press processing due to increased processing lot numbers ■ Prototyping using simple molds with consideration for mass production *For more details, please refer to the related links or feel free to contact us.
