Stamping is a manufacturing process that involves applying pressure to a material to deform it into a desired shape or size. There are various types of stamping processes utilized in the industry, each with its unique set of advantages and disadvantages. In this article, we will describe some of the most common types of stamping processes.
Overall, stamping is a versatile manufacturing process that plays a crucial role in the production of a wide range of metal parts and components. By understanding the different types of stamping processes, manufacturers can select the most suitable process for producing high-quality parts in an efficient and cost-effective manner.

The relationship between the shell type and the template temperature and the crust time. If the template temperature is not enough or the shelling time is too early, the shell tooth surface portion cannot be fully cured. Long time, the sand is easy to fall off, resulting in rough surface of the shell tooth surface, affecting the quality of the cast tooth surface. After this kind of situation, the double cone rotary vacuum dryer can be used in the drying box for heating for a period of time before use. The curing temperature is generally 240 to 260 °C.
The shell-type demoulding should carefully clean the residual sand in the shell type, transport and store it, and the shell-shaped tooth surface should not be damaged. When assembling the shell type before casting, the sand should not fall into the sand. The casting temperature is low, and the contour of the tooth surface is unclear, inclusions, pores, etc., and the root of the tooth is also prone to wrinkles, but the casting temperature is too high, and it is easy to produce sticky sand. The suitable casting temperature is 1400 ~ 1450 °C.
Heat treatment process heating equipment: 45kW box type electric furnace quenching equipment: coal-fired salt bath furnace, thermocouple temperature measuring salt bath: nitrate, nitrite heat treatment process. If the as-cast carbide is excessive or distributed in a network, it is difficult to machine, and a high-temperature graphitization annealing process can be added before roughing. Mechanical properties The mechanical properties of the gear material were taken from a wedge-shaped sample cast with molten iron and heat treated with the gear in the same furnace.
Blanking: Blankings are flat pieces of sheet metal that have been precisely cut and punched out from larger sheets of metal. Blanking is a process used to produce these flat pieces, and is ideal for producing large quantities of uniform, flat parts.
Coining: Coining is a stamping process used to create impressively flat and precise features - often used in creating coins or bearing seals.
Drawing: Drawing involves pulling a flat piece of metal through a die with a punch tool to form it into a three-dimensional shape. This process is commonly used in the creation of products such as automobile fenders, cans, and ship hulls.
Embossing: Embossing is the process of applying raised designs or patterns to a flat piece of metal by impressing the metal with a die. This process is popularly used in the production of decorations and signage.
Piercing: Piercing is the process of punching or drilling holes in a metal sheet. It is widely used in creating products such as luggage tags, name plates, and metal attachments.
Blanking and forming: Blanking and forming involve using a single die to create a part that has a variety of features, both flat and formed. It is a highly efficient process for creating complex parts.
