Necking

Necking is a manufacturing process that involves reducing the diameter of one end or a section of a metal tube or rod by applying localized compressive forces, often using specialized tools or dies.

This technique is used to create transition zones or dimensional adjustments in tubes, making them suitable for specific applications such as assembly or connection with other components.

The necking process reinforces the structure of the tube and improves its mechanical resistance in the affected areas.

The process for shrinkage

Discover the industrial process of shrinkage, a technique for transforming metal tubes that is essential in many industrial sectors. Here are the key steps in this process to reinforce and adapt the tubes to specific applications.

1. Preparing the tube

The metal tube is inspected to ensure compliance with the required specifications.

2. Marking the restricted area

A specific area on the tube is marked to indicate the location of the recess.

3. Fixing the tube

The tube is fixed in the shrinking machine to ensure its stability during operation.

4. Diameter reduction

A specialized tool is used to apply controlled force to the marked area, thereby gradually reducing the diameter of the tube.

5. Dimension control

The shrinking machine is equipped with measuring devices to precisely control the size of the tube during operation.

6. Removing the tube

Once the shrinkage is complete, the tube is removed from the machine and inspected to verify the quality of the shrinkage.

7. Finish (if required)

The tube may be subjected to complementary operations such as cleaning or surface treatment to meet the specific requirements of the application.
