Stainless steel water cup production process--- Necking，What is the necking process?

Necking is a special process in the processing of stainless steel water cups. Most types of stainless steel water cups do not require a necking process in processing, and only some specially designed cups will use the necking process. What is the necking process?

The simple understanding of the necking process is to reduce the large cup mouth and process it into a small diameter cup mouth. The necking process not only has professional requirements for equipment in processing, but also requires the processing experience of the staff. Since the necking process more uses manual necking, it is not a small process challenge to control the diameter of each necking of the water cup to be the same. It is strictly required that the diameter error of the mouth of the water cup through the necking should be controlled within ±0.1 mm.

Some water cups are relatively simple in structure and less difficult to shrink in the production and processing process, and can be directly cold-shrinked by a shrinking machine. However, some water cups are complicated in structure and difficult to shrink.

When shrinking, the mouth of the product must be heated at a high temperature to change the hardness of the stainless steel to achieve the effect of shrinking. This process is also called quenching.

In the entire production process of stainless steel water cups, the necking process is a link with high difficulty and high rate of defective products. Therefore, the shrinking quality of a drinking glass can also show the technical ability of the workers in this factory.
