Application of Deep Drawing in Vehicle Industry

Deep Drawing

Deep Drawing is widely used in the vehicle industry, and its high-precision, high-efficiency and diversified shape manufacturing capacity provides important support for vehicle manufacturing. The following is a clear summary of Deep Drawing’s application in the transport industry:

1、 General Overview
Deep Drawing is a process of punching sheet metal into hollow cylinders or other complex shapes. In the transportation industry, this process is widely used to produce various parts to meet the requirements of the vehicle for structural strength, aesthetics and functionality.

2、 Specific application

Body and chassis structure
Structural parts: Deep Drawing can produce various structural parts of body and chassis, such as frame beam and longitudinal beam. These parts are formed by deep drawing process, with high strength and good deformation resistance, providing stable support for the vehicle.
Parts with complicated shapes: Deep Drawing can manufacture the body covering parts with complicated shapes, such as door inner plate and engine hood, by adjusting the mould and process parameters. These components not only meet the structural requirements, but also have good appearance quality.

dynamic system
Engine parts: Deep Drawing is also used in the manufacturing of engine parts, such as oil pan, crankcase, etc. These parts are formed by deep drawing process, with good sealing and leakage resistance, so as to ensure the normal operation of the engine.
Transmission system: some parts of the transmission system, such as clutch housing and transmission housing, are also manufactured by Deep Drawing process. These components are subjected to large loads and impacts and the deep drawing process ensures their strength and durability.

Interior and exterior trimming
Interior trimming: Although the direct application of Deep Drawing in interior trimming parts is relatively rare, some interior trimming parts requiring high strength and complex shapes may still be manufactured by this process or as part of the manufacturing process.
Exterior trimming: Some metal decorative parts or structural parts of exterior trimming may be preliminarily shaped or machined by deep drawing process to meet their specific shape and size requirements.

The drawing process can also play an important role in other vehicle manufacturing. For example, in the aerospace sector, it can be used to manufacture some parts of an aircraft; In the field of rail transit, it can be used to produce some structural parts or interior parts of trains, etc.

The advantages of the drawing process include:
Capable of manufacturing parts with large depth and complex shape;
Relatively high material utilization rate;
Good dimensional accuracy and surface quality can be obtained.
