Metal fabrication is a core component of modern manufacturing, spanning various fields from automotive and aerospace to electronics and building structures. Understanding the basic processes, materials, and applications of metal fabrication can help potential customers make informed decisions. In this guide, we will introduce some of the most common metal fabrication techniques to help you gain insight into this industry and select the right approach for your project.
Common Metal Fabrication Techniques and Their Applications
1.Stamping
Stamping is a process that converts flat metal sheets into specific shapes through methods such as punching, bending, shearing, and embossing. It is highly suitable for mass production and is commonly used in the automotive industry for manufacturing body panels and brackets. Its efficiency and high material utilization rate make it an economical and effective process for a wide range of industries. Additionally, stamping is frequently used for producing electronic product casings and household appliance parts due to its precision and speed.
2.Die Casting
Die casting involves injecting molten metal into a steel mold under high pressure to produce metal parts with high precision and complex shapes. Materials like aluminum, zinc, and magnesium are commonly used in die casting, ideal for products requiring intricate details and smooth surfaces. The automotive industry extensively uses die casting to manufacture critical parts such as engine components and transmission housings. In addition, die casting is used in aerospace for producing lightweight structural parts and in electronics for making heat sinks.
3.Extrusion
Extrusion is a process in which heated metal is pushed through a die to produce parts with a fixed cross-sectional shape. Aluminum is the most common material used in extrusion and is particularly suitable for manufacturing long components like pipes, window frames, and heat sinks. Extrusion is widely used in the construction industry to create frames and support structures. Additionally, in electronics and industrial applications, extrusion is used to produce profiles with uniform cross-sections, ensuring structural strength and dimensional stability.
4.CNC Machining
CNC (Computer Numerical Control) machining is a highly precise process used to cut, drill, mill, and turn various materials. CNC machining is ideal for producing complex and precise parts, commonly used in the automotive, aerospace, and medical industries. CNC machining can handle metals like aluminum, stainless steel, and even titanium, making it perfect for producing engine parts, aircraft components, and medical equipment.
Common Metal Materials
Aluminum
Aluminum is a lightweight metal with high strength and corrosion resistance, commonly used in extrusion and die casting. It is ideal for applications that require a combination of light weight and strength, such as automotive bodies, building materials, and electronic heat sinks.
Stainless Steel
Stainless steel is known for its corrosion resistance and durability, widely used in stamping and CNC machining. It is perfect for applications in food processing equipment, medical devices, and building materials that require high strength and durability.
Copper
Copper has excellent electrical and thermal conductivity, making it a key material in the electronics and electrical industries. Copper is often used in CNC machining and stamping to manufacture electronic components, cable connectors, and heat dissipation systems.
Magnesium
Magnesium is one of the lightest structural metals, often used in die casting. It is ideal for producing lightweight parts such as automotive components and aerospace parts.
