The difference between stamping parts and casting parts
Author:
Definition of 1. Stamping and Casting Parts
Stamping is a kind of metal parts made by shearing, punching, bending, stretching and other forming processes of metal sheet or strip in the mold. The casting is a metal component that is cooled and solidified by injecting a molten metal or alloy into a mold.
The difference between 2. stamping parts and casting parts
1. Different manufacturing methods
Stamping parts are formed by shearing, punching, bending and stretching of metal plates or strips in the mold, while casting parts are cooled and solidified by injecting molten metal or alloy into the mold.
2. Different applicable materials
Stamping parts are mainly suitable for thin plates or strips, such as stainless steel, aluminum alloy, iron alloy, etc., while casting parts are suitable for steel, copper, aluminum, zinc and other alloy materials with lower melting point.
3. Processing accuracy is different
Since the stamping parts are formed by molds, their processing accuracy is high and their dimensional stability is good, while the casting parts are affected by the shrinkage of the mold and the temperature changes during metal solidification, and the dimensional accuracy is usually low.
4. Process complexity is different
Stamping parts process is simple, high production efficiency, especially suitable for mass production; casting parts are related to liquid metal injection, cooling and solidification process, more difficult to master and operation.
3. their respective advantages and disadvantages
1. The advantages of stamping parts
The advantages of stamping parts are low manufacturing cost, high production efficiency, high precision and good surface finish.
2. The shortcomings of stamping parts
The main disadvantage of stamping parts is that the thickness of the material is difficult to exceed 3mm, and there will be deformation after stamping, which requires maintenance, replacement and repair of the mold.
3. The advantages of casting
The advantages of casting parts are that various shapes and large parts can be manufactured, and the materials can be selected from metals and alloys with lower melting points.
4. The shortcomings of casting
The main disadvantages of casting are the relatively high manufacturing cost and low surface finish.
In summary, stamping parts and casting parts have their own advantages and disadvantages, and the choice of which way to produce parts is based on specific application scenarios and requirements.
