4 Key Advantages of Wet Shot Peening

Posted on by Admin

Water to be used for Wet Shot Peening in AucklandIn treating metal surfaces, sandblasting is the usual go-to technique. While this method works effectively, a modern process called wet cold blasting or wet shot peening comes with a few advantages over the older technique.

  1. No Need for Degreasing

With wet shot peening, you no longer have to degrease metal parts. You can put directly the greasy metal parts into the machine. Skipping the degreasing step in the process will save you money and labour time.

  1. Less Media or Blasting Product

You can’t run a blasting machine without enough amount of blasting media. However, in wet, cold blasting, you’ll only need a little amount of cleaning media as the water in this method has a cushioning effect on the media. As a result, you may reuse the blasting product for several times before replacing them.

  1.  Reduced Cleaning Time

In sandblasting, metal parts usually come out of the machine covered with leftover dust from the blasting product. But after peening, metal parts come out completely clean. So, you no longer have to spend time dusting off each part before moving to final plating operations.

  1. Smoother Finish

Since the material is wet while on the machine, it conforms better during the blasting process. So, not only the parts come out clean after peening, but they also have a smoother finish. Stainless steel, brass, and aluminium usually come out with an attractive satin finish after a wet blasting. In addition, metal parts with intricate designs often look detailed and etched after the treatment.

Above all, wet blasting is a dust-free process. Hence, you lower the risk of the harmful effects of dust particles when inhaled. But despite these key advantages of wet blasting over dry methods, you still have to know whether this technique is ideal for your material.
