What is the Difference Between Forged Cylinders and Cast Cylinders?
The forged cylinder is slowly formed and needs to go through multiple processes to complete, while the cast cylinder is formed at one time, the process flow is relatively simple, and the equipment requirements are low. In addition to being different in the process flow, there are also certain differences in materials, performance, cost and production efficiency. Therefore, when purchasing cylinder products, it is necessary to choose the most suitable forged cylinders or cast cylinders product according to different application scenarios.
Forged cylinders and cast cylinders are two different metal forming processes, and their main differences are reflected in the manufacturing process, materials, properties and fields of application.
1. Manufacturing Process
Forged cylinders, as the name suggests, uses a forging process. Forging cylindrical shape is to use forging equipment to apply a certain pressure to the metal blank heated to a high temperature state to cause plastic deformation to produce a cylindrical shape with certain mechanical properties, shape and size. In the process of forged cylinders, pressure is applied to the metal material, usually by forging, hammering and other methods. According to the forming mechanism, the forged cylinders can also be divided into free forging cylinders, die forging, rolling ring cylinders and special forged. Forged cylinders products through forging, so that the metal material has higher strength, wear resistance, corrosion resistance and tensile properties, etc., and can eliminate the looseness of the metal as cast, welding holes, the mechanical properties of forgings are generally better than the same material castings.
The cylindrical casting is to heat the metal to a liquid or semi-solid state, then pour the molten metal into a cylindrical mold that meets the requirements, and wait for cooling and solidification to form a cylindrical casting (cylindrical blank) of specific shape, size and performance. Casting technology is an earlier metal thermal processing method mastered by human beings. It can produce cylindrical castings with relatively complex shapes and has a wide range of applications. Casting can also be divided into gravity casting and low pressure casting.
2. Materials
(1) The raw material usually used for forging cylinder is block or bar metal blank. The forged cylinders processed by forging plastic deformation have better mechanical properties and structure.
(2) The casting cylinder is made of liquid metal or alloy. Casting is the direct injection of molten metal into a mold, and the resulting casting has a relatively loose structure and may have slightly inferior mechanical properties.
3. Performance
Through the forged cylinders, the forged cylinders can better control the internal structure and external shape of the material. The grain structure of the metal material will be improved, the grain will be refined, and the structure will be more dense, so that the forged cylinders has higher strength and The toughness, stability and quality will be better, and it can also greatly reduce waste generation and improve material utilization.
The cast cylinder is limited by the mold, and it can produce cylindrical castings with relatively complex shapes, ranging from a few grams to hundreds of tons. It has wide adaptability, relatively simple process, low cost, safety factor and high strength. Although casting can produce complex shapes, it forms a structure with large grains, its strength and toughness are relatively low, and the control of the internal structure and mechanical properties of the material is usually relatively poor, and dust, harmful gases will be generated during the casting process.
4.Field of Application
(1) Forged Cylinders: It has good mechanical properties and mechanical properties, and is often used in occasions that require high strength, toughness and wear resistance, such as automobiles, engineering machinery, aerospace and other fields.
(2)Cast Cylinders: Casting has the advantages of low production cost, short manufacturing cycle and is suitable for mass production. It is often used in occasions that require high sealing and surface finish, such as metal parts manufacturing, valves, water pumps and other fields.
In general, compared with cast cylinders, forged cylinders have better mechanical properties, are stronger, have higher strength, can withstand greater loads and pressures, and have longer service life. And during the forging process, the metal material can be precisely controlled and shaped to ensure that the size and shape of the forged cylinders meet the requirements. The cylinder of castings also has its corresponding advantages, so when choosing a forged cylinders forgings manufacturer, which manufacturing method to choose needs to be determined according to specific needs and requirements, so as to ensure that the final product has the required performance and quality.
