At our facility, we specialize in metal stamping, including the development and production of progressive dies and fourslide tools, as well as precision machining. In addition, we offer secondary manufacturing services such as deburring and tapping. Our expertise in metallurgy, combined with exceptional customer support, ensures that your stamped and formed metal workpieces will have optimal geometry, with precise tolerances, even at thicknesses as thin as one thousandth of an inch.
The process of Stamping, also referred to as Pressing, involves the transformation of flat metal sheets, either in blank or coil form, into a specific shape using a stamping press and a tool and die surface. This process includes several sheet metal forming techniques, such as punching with a machine press, blanking, embossing, bending, flanging, and coining. The formation of the metal part can take place in one step, where each press stroke results in the desired shape, or through several stages. The method is typically applied to sheet metal, but can also be utilized on other materials such as polystyrene. Progressive dies are typically fed from a steel coil, which is unwound and leveled before being advanced into the press and die at a specified feed length. The number of stations in the die depends on the complexity of the part.
The process of Deep Draw Manufacturing involves transforming metal into a smooth, seamless round, square, or rectangular container, known as an enclosure or case. The height of the case produced through this method is typically at least double its diameter. Deep drawn enclosures are utilized to house technology in demanding conditions or when tight precision and dependability are necessary.
The process begins by positioning a flat piece of metal, known as a blank or disc, over a die, which is a cavity. Then, a punch forces the metal through the die, shaping it. The precision punches and dies utilized in this process are called tooling. The tooling is set up in power presses that generate the required force to drive the material through the drawing process. During the process, the material is molded into the shape of the die through pressure applied to the blank and lubrication used on either the die or the blank. Each drawing step, also referred to as a reduction, reduces the diameter and increases the height of the part. It may take five or more reductions to achieve the final shape, with factors such as the material type and thickness, corner and bottom radii, and shape determining the required number of reductions.
Progressive Die Stamping
Progressive Die Stamping involves the use of a metalworking device known as a die that transforms flat strips of metal into completed parts by way of a series of stamping stations. The die, which is housed in a stamping press, opens as the press moves upward and closes as it moves downward. The metal strip is fed through the die a precise amount with each press stroke, undergoing cutting, bending, and other forming operations until the final metal part is produced. The part remains connected to the metal strip as it advances through the die and is precisely positioned by pilots. The components of the die, which vary for each part, are located and guided by plates and pins, and the entire process is powered by the mechanical press. The feed progression and precise alignment of the strip are maintained by the press feeding mechanism and conical pilots.
Fine-blanking is a precise forming method that creates metal components with smooth edges across the entire piece in a single forming action using a small die clearance compared to traditional blanking. The process eliminates the need for additional secondary operations, reducing production time and costs. As a result, it is widely utilized in the production of various items such as automobile components, aircraft parts, and precision machinery.
