What's the difference between stamping and die-casting?

Stamping is a kind of metal processing method that is based on the plastic deformation of the metal and the use of molds and stamping equipment to apply external force to the plate, strip, pipe, and profile so that it produces plastic deformation or separation so as to obtain the required shape and size of the workpiece (stamping parts).

Stamping features:

1.Stamping is a processing method with high production efficiency and low material consumption. Suitable for the production of large quantities of parts and products, easy to achieve mechanization and automation, have a high production efficiency, and at the same time can strive to do less waste and no waste production. Even if there are leftover materials, they can also be made full use of.

2.The operation process is convenient and does not require the operator to have a higher level of skills.

3.Stamping parts generally do not need to be machined with high dimensional accuracy.

4.The stamping parts have good interchangeability. The same batch of stamping parts. It can be exchanged without affecting the assembly or product performance.

5.Because the stamping parts are made of plates, their surface quality is good, which provides convenient conditions for the subsequent surface treatment processes (such as electroplating and spray painting).

6.Stamping processing can obtain high strength, high stiffness, and light-weight parts.

7.It can make complex-shaped parts that are difficult to process by other metal processing methods.

Die-casting is the process of unifying pressure, speed, and time by using three elements, such as machine, die, and alloy. A process in which alloys, such as aluminum, copper, etc., are melted into a liquid state and then scooped into a die-casting machine and made out of die-casting molds. For the thermal processing of metals. Die casting is a type where most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys.

Die casting classification:

1. The existence of pressure means that the die-casting process is different from other casting methods. Pressure casting is a special casting method in modern metal processing technology. It is the process of filling the molten metal at high pressure and speed and crystallizing at high pressure to form the casting.

The metal casting process is characterized by the use of the mold cavity to apply high pressure to the melted metal. MDs are usually made of stronger alloys, a process somewhat similar to injection molding.

Storing characteristics:

Die casting is a casting method. Through die casting and casting, the die casting size tolerance is very small, the surface precision is very high, and in most cases, the die casting without further machining can be assembled and applied. Threaded parts can also be directly cast out.
