MFB manufactures mechanical components using fine blanking, conventional blanking, sizing, drawing, precision machining, prototyping, design and manufacturing of dies, assembly lines.
Fine blanking is a sheet metal machining technology. It allows manufacturing ready-to-use functional components thanks to high-precision, perfectly and smoothly cut surfaces.
Conventional blanking is the most versatile blanking procedure. Thanks to the combined use of feeding lines, presses and dies, all sorts of different mechanical components can be manufactured, such as bearing plates, closed boxes with bending and riveting, small drawn components, large and complex shaped plates complete with bending and threading. Today, this technology has become so sophisticated that unprecedented operations, which were unthinkable of only a few years ago, have now become feasible. It is now possible to make use of independent threading, drilling and bending units, in synchrony with the machine cycle. It is also possible to use state-of-the-art machines equipped with special kinematic mechanisms and further auxiliary equipment, such as air cushions, hydraulic cylinders, powerful gas springs. The factors that make this technology extremely competitive are cost-effectiveness and repeatability induced by full automation and low costs of equipment manufacturing.
The drawing technology allows manufacturing hollow pieces starting from metal sheets or flat strips. Special matrixes and punches forge the material into the desired shape. Strip-fed progressive dies are used for dishing, otherwise disk-fed or blank-fed compound dies are used. Drawn pieces usually feature a low reduction in the thickness of drawn parts and walls free of cracks, which are due to material deformation, and high repeatability. The use of suitably structured materials to be drawn, high-performance lubricants, special surface coatings of matrixes and punches, as well as a proper forging sequence and a high corporate know-how are the fundamental elements of this major manufacturing process.
Remachining occurs downstream the blanking processes. It is the natural step to further process all those components that require finishing and / or features otherwise impossible to obtain.
Specially designed machines, tools and equipment are used for grinding flat and round surfaces, threading, drilling, boring, chamfering, and so on. These machines are very often optimized for the type of machining to be carried out to assure a high degree of productivity and repeatability. Poka-joke systems are used to avoid any human mistakes in the positioning of components on the piece holding equipment. These systems have always been considered to be an integral part of the process.
The assembly of small units made up of special components manufactured by MFB has always been a service requested by customers. Certified and tested assembly units are provided thus allowing customers to directly feed the production lines that manufacture machines or mechanisms. Assembly is carried out without joining elements by means of press riveting and welding with or without filler metal or with joining elements, such as nails, rivets, screws, and so on.
Fine blanking dies
Thanks to dies designed and created with the appropriate construction criteria, together with presses equipped with multiple hydraulic forces, and the use of specific materials and lubricants, MFB manufactures components featuring extremely precise dimensions and geometries.
