Company information
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.
