Integrated technology of precision welding and stamping
Integrated technology of precision welding and stamping
In the modern manufacturing industry, simple parts forming is often only part of the value chain. It is becoming a mainstream trend to integrate multiple stamping parts into a functional component by precision welding. The integration of precision welding and stamping represents the value transition from manufacturing parts to manufacturing components, providing greater freedom and integration for product design.
The core advantage of this integration technology is to reduce the assembly process, improve the structural strength and reduce the total cost. A typical example is the inner panel of an automobile door, which is usually made of multiple precision stampings such as outer steel plates, stiffeners, and mounting brackets, and the parts are assembled by robot spot welding. If these parts are produced by different suppliers and then transported to the assembly plant, it will face the problems of complex logistics, cumulative error of precision and high management cost. A company that can provide stamping services and integrate welding capabilities can produce all stamping parts in the same plant and assemble them with high accuracy and efficiency using welding fixtures and robots, ensure dimensional stability and consistency of final components.
To achieve this goal, the front of the precision stamping, the process put forward very high requirements. For the stamping parts used for welding and assembling, the outline dimensions and the flatness of flange edges must be strictly controlled. Any out-of-tolerance deformation or burrs will affect the positioning accuracy of the welding fixture, resulting in unstable welding quality, or even virtual welding, penetration and other defects. Therefore, for the production of such parts of the metal stamping die, must have high precision and stability. In some cases, there are even specialized metal stamping dies on the market for the production of critical parts in such welded assemblies.
From a technical point of view, in addition to traditional spot welding, laser welding is also increasingly used in precision welding and stamping, the production of components. Laser welding has the advantages of small heat affected zone, small deformation, beautiful weld and high strength, which is very suitable for components with requirements for appearance and sealing, such as battery trays of new energy vehicles and shells of high-end home appliances. Choosing a partner with precision stamping, welding, and dual capabilities means you get not just a bunch of parts, but a ready-to-use, reliable function module, this greatly simplifies your supply chain and speeds up the time-to-market process.
