HY introduces you to other aspects of stamping

Stamping

A forming processing method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size.

Metal injection molding

It is a new type of powder metallurgy near net shape technology derived from the plastic injection molding industry. As we all know, plastic injection molding technology can produce products of various complex shapes at low prices, but the strength of plastic products is not high. In order to improve its performance, it can Add metal or ceramic powder to plastic to obtain products with higher strength and good wear resistance. In recent years, this idea has evolved to maximize the solid particle content and completely remove the binder and densify the parison during the subsequent sintering process. This new powder metallurgy forming method is called metal injection molding.

Turning

Lathe processing is a part of mechanical processing. Lathe processing mainly uses turning tools to turn rotating workpieces. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used processing technology in machinery manufacturing and repair factories. Turning is a method of cutting the workpiece on a lathe by rotating the workpiece relative to the tool. The cutting energy in turning is mainly provided by the workpiece rather than the tool. Turning is the most basic and common cutting processing method and plays a very important role in production. Turning is suitable for processing rotating surfaces. Most workpieces with rotating surfaces can be processed by turning methods, such as internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooves, threads and rotary forming surfaces, etc.

Milling

Milling is to fix the blank and use a high-speed rotating milling cutter to cut out the required shapes and features. Traditional milling is mostly used for milling simple shapes/features such as contours and slots. CNC milling machines can process complex shapes and features. The milling and boring machining center can perform three-axis or multi-axis milling and boring processing, and is used for processing molds, inspection tools, molds, thin-walled complex curved surfaces, artificial prostheses, blades, etc.

metal deposition

It is somewhat similar to the "cream-squeezing" type of fused deposition, but the metal powder is ejected. While the nozzle sprays metal powder materials, it also provides high-power laser and inert gas protection. This will not be limited by the size of the metal powder box, can directly manufacture larger parts, and is also very suitable for repairing partially damaged precision parts.

roll forming

The roll forming method uses a series of continuous stands to roll stainless steel into complex shapes. The sequence of rollers is designed in such a way that the roller profile of each stand continuously deforms the metal until the desired final shape is obtained. If the shape of the part is complex, up to thirty-six racks can be used, but for parts with simple shapes, three or four racks will suffice.

Die forging

It refers to the forging method that uses a die to shape the blank on special die forging equipment to obtain forgings. The forgings produced by this method have precise dimensions, small machining allowances, complex structures and high productivity.

Die-cutting is the blanking process. The film formed in the previous process is positioned on the male die of the die-cutting die. The excess material is removed by closing the die, retaining the 3D shape of the product and matching it with the mold cavity.

Die cutting process - die

In the knife die blanking process, the film panel or circuit is positioned on the base plate, the knife die is fixed on the machine template, and the force provided by the machine's downward pressure is used to control the blade to cut the material. What makes it different from the punching die is that the incision is smoother; at the same time, by adjusting the cutting pressure and depth, it can punch out effects such as indentations and half-breaks. At the same time, the cost of molding is low and the operation is more convenient, safe and fast.
