In the industrial set up of the economy, the printing machines are growing in large numbers. Different printing techniques and processes are used by every industry for effective communication. Any machine used in printing ink on the substrate (printing medium) which can be cloth, paper or plastic, is referred to as the printing machinery. By applying pressure to the substrate, the printing machinery transfers the ink on the printing medium resting on an inked platform composed of movable type. The development of industrial printing machines changed a lot of things in the world. It would make transfer and preservation of historical records, scientific findings, and knowledge easy and possible. There’s a great advancement in the printing machinery introduced in the market today given the improvement in science and technology. There’s a competition in the industry, as many companies are now making printing press. As every company is introducing better features and making an effort to overcome the other competitors, this has led to the introduction of many enhanced features in printing machinery. With the introduction of various features in these types of machinery, printing is now easier to be done than it was in earlier days.

Today, printing machinery is available in many sizes to suit different needs. Bigger sizes of printing machinery are available for heavy-duty printing or big-time printing businesses. You can get small and medium sizes too for small and medium printing businesses. The machinery size determines the volume of printing that will be done in a day, to a greater extent. When compared with small-sized printing machinery, the heavy industrial printing machines can print a lot of things per hour or regularly. There are different types of printing machines for printing on a different medium since different printing machines make use of different printing technology. Each of the below-mentioned printing machinery is meant to serve a particular purpose. You must consider your printing needs or the type of printing that you are doing before you want to buy or order for your printing machine. Several factors such as the size, the type of printing done, the seller, the brand, and others determine the cost.

The digital printing machines have gained immense popularity for short to medium run jobs requiring high clarity, quality, and fine printing. A vibrant quality image is delivered with these types of printers. By providing cost-effective and fine printing solutions, these affordable and high-performance machines are revolutionizing the printing industry. Because of the on-demand services, digital printing equipment ensures fast turnaround time. Digital printers are ideally suited to publish a small print run of posters and books. They have many advantages over traditional methods.

Understanding Metal Stamping

Metal stamping is a cold-forming process that makes use of dies and stamping presses with rewinding machine to transform sheet metal into different shapes. Pieces of flat sheet metal, typically referred to as blanks, is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. Production facilities and metal fabricators offering stamping services will place the material to be stamped between die sections, where the use of pressure will shape and shear the material into the desired final shape for the product or component.

This article describes the metal stamping process and steps, presents the types of stamping presses typically employed, looks at the advantages of stamping compared to other fabrication processes, and explains the different types of stamping operations and their applications.

Basic Concepts of Metal Stamping Machine

Metal stamping, also referred to as pressing, is a low-cost high-speed manufacturing process that can produce a high volume of identical metal components. Stamping operations with slitting machine are suitable for both short or long production runs, and be conducted with other metal forming operations, and may consist of one or more of a series of more specific processes or techniques, such as:

Punching

Blanking

Embossing

Coining

Bending

Flanging

Punching and blanking refer to the use of a die to cut the material into specific forms. In punching operations, a scrap piece of material is removed as the punch enters the die, effectively leaving a hole in the workpiece. Blanking, on the other hand, removes a workpiece from the primary material, making that removed component the desired workpiece or blank.

Embossing is a process for creating either a raised or recessed design in sheet metal, by pressing the raw blank against a die that contains the desired shape, or by passing the material blank through a roller die.

Coining is a bending technique wherein the workpiece is stamped while placed between a die and the punch or press. This action causes the punch tip to penetrate the metal and results in accurate, repeatable bends. The deep penetration also relieves internal stresses in the metal workpiece, resulting in no spring back effects.

Bending refers to the general technique of forming metal into desired shapes such as L, U, or V-shaped profiles. The bending process for metal results in a plastic deformation which stresses above the yield point but below the tensile strength. Bending typically occurs around a single axis.

Flanging is a process of introducing a flare or flange onto a metal workpiece through the use of dies, presses, or specialized flanging machinery.

Metal hot stamping machines may do more than just stamping; they can cast, punch, cut and shape metal sheets. Machines can be programmed or computer numerically controlled (CNC) to offer high precision and repeatability for each stamped piece. Electrical discharge machining (EDM) and computer-aided design (CAD) programs ensure accuracy. Various tooling machines for the dies used in the stampings are available. Progressive, forming, compound, and carbide tooling perform specific stamping needs. Progressive dies can be used to create multiple pieces on a single piece simultaneously.
