By changing the material, we eliminate the quenching process and achieve cost reduction!

This is a technical proposal example for the production of driven gears. In the case of the product mentioned here, the conventional method required component strength, so after machining with S45C material, heat treatment was performed to achieve the necessary strength. However, due to the product's weight (300g), there were challenges regarding the cost of heat treatment. Therefore, we proposed a method transition to "780 high-tensile material" combined with precision shearing processing. This allowed us to manufacture a product that previously took three days in just a few hours, achieving a 40% cost reduction as a result. [Case Overview] ■ Before Proposal: Ensured strength through heat treatment ■ Effect: 40% cost reduction by eliminating heat treatment through material change to "780 high-tensile material" *For more details, please refer to the related links or feel free to contact us.

We can provide consistent support from prototype development to mass production using molds. We can accommodate plates up to 6 mm and will create molds that combine the application of cold forging technology and precision shearing processing. While a certain level of initial investment is required, there is potential for significant cost reduction compared to existing methods. Please consider utilizing our services for transitioning from existing methods to pressing and for the development of new parts in your press production facility.
