Types of stamping

We offer single and multistage, progressive die, deep draw, fourslide, and other stamping methods to ensure the most effective method for manufacturing your products. Xinzhe’s experts can match your project with the appropriate stamping by reviewing your uploaded 3D model and technical drawings. 

• Progressive Die Stamping uses multiple dies and steps to create deeper parts than would typically be achievable through single dies. It also enables multiple geometries per part as they go through various dies. This technique is best suited to high volume and large parts such as those in the automotive industry. Transfer die stamping is a similar process, except progressive die stamping involves a workpiece attached to a metal strip pulled through the entire process. Transfer die stamping removes the workpiece and moves it along a conveyor. 
• Deep Draw Stamping creates stampings with deep cavities, like enclosed rectangles. This process creates rigid pieces since the extreme deformation of the metal compresses its structure into a more crystalline form. Standard draw stamping, which involves shallower dies used to shape the metal, is also commonly utilized. 
• Fourslide Stamping shapes parts from four axes instead of from one direction. This method is used to manufacture small intricate parts including electronics components such as phone battery connectors. Offering more design flexibility, lower production costs, and faster manufacturing times, fourslide stamping is popular in aerospace, medical, automotive, and electronics industries. 
• Hydroforming is an evolution of stamping. Sheets are placed on a die with a bottom shape, while the upper shape is a bladder of oil that fills to high pressure, pressing the metal into the shape of the lower die. Multiple parts can be hydroformed simultaneously. Hydroforming is a quick and accurate technique, though it requires a trim die to cut the parts out of the sheet afterward. 
• Blanking cuts pieces out from the sheet as an initial step before forming. Fineblanking, a variation of blanking, makes precise cuts with smooth edges and a flat surface. 
• Coining is another type of blanking that creates small round workpieces. Since it involves significant force to form a small piece, it hardens the metal and removes burrs and rough edges. 
• Punching is the opposite of blanking; it involves removing material from the workpiece instead of removing material to create a workpiece. 
• Embossing creates a three-dimensional design in the metal, either raised above the surface or through a series of depressions. 
• Bending happens on a single axis and is often used to create profiles in U, V, or L shapes. This technique is accomplished by clamping one side and bending the other over a die or pressing the metal into or against a die. Flanging is bending for tabs or parts of a workpiece instead of the whole part.
