Introducing the applications of "beautiful shear surfaces" and examples of machining for cam function components!

If there are no instructions on the drawing, the finish of the "shear surface" for standard pressed parts is not considered important. So, in what cases is a "clean shear surface" necessary? While we may not know the specific applications of the parts, we will consider this based on information from our customers. For the products we manufacture, there are often instructions regarding the "shear surface" on the drawings, such as "ensure over 70% shear surface" or, conversely, expressions like "the combined area of the fracture surface and the droop surface should be 30% or less." *For detailed content of the column, please refer to the related links. For more information, 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.
