ALPHA

Fixed stroke, Crank motion, High presicion

The ALPHA series are recognized as Yamada's best-selling crank motion press due to its simple mechanism (2 plungers and 4 posts slide guide), high speed, and high precision for many different types of stamping applications like connectors, electrical components, washers and motor lamination. Its very rigid frame made in casting iron guarantees an optimal rigidity and very low bed distortion. As all Yamada dobby presses the ALPHA series are equipped with an automatic oil temperature control (heat&cool system) which an optimal stability of the slide penetration from the first stamped parts at any constant speed or in acceleration.
