Thinking About Doing Your Own Shot Peening?

There are a number of considerations that are critical when evaluating the feasibility of doing shot peening in-house.

1. How many different peening operations will be required for your parts?

For optimum production flow, each different operation may require a different machine, thus adding to start upcapitalexpenses and on-going operational expenses. ID and OD peening, shot and glass bead peening,and large and small parts are all factors that may necessitate additional machines.

2. What is your current air compressor capacity?

Pneumatic peening machines require a large volume of clean, dry, and uninterrupted air. Typically, air dryers are needed to keep moisture out of the system.

3. Where do you plan to install the the equipment?

By their very nature shot peening machines increase the noise level and may create a dust laden environment that can be incompatible with many manufacturing operations.

4. How will machine down time affect your manufacturing workflow?

Over time a peening machine will “eat itself up” from the inside. Replacement and repair of such items as nozzles, cabinet walls, motors, holding fixtures and air lines are necessary on a regular basis and may require sudden and immediate attention.

5. How reliable will your source of shot be?

Good quality peening media in accordance with AMS 2431 is fundamental to the process. Shot can frequently be a back ordered item with a qualified supplier, causing serious delays in production. Therefore it is imperative to maintain a substantial inventory of peening media.

6. Have you fully considered all the quality requirements for the shot peening specification?

In addition to needing trained and qualified operators, additional important requirements under most shot peening specifications include process development, equipment, and process shot control.

7. Do you have enough peening workload to justify doing the work in-house?

Unless machines operate at high capacity levels, they can be expensive to run. An outside peening source may be a more economical alternative.

8. Do you believe that by having the shot peening process in-house, you will improve inventory turns?

If you had a dedicated supplier in close proximity, could you better invest your capital allocation elsewhere? If an approved supplier operated a shot peening department in your facility, would this be an alternative solution?
