Publication comments on total cost of product failure

While recently reviewing a engineering simulation publication (Advantage, VOL VII, ISSUE 2), I came across several text excerpts that resonated with the focus of LSP Technologies.

From the article “Keeping Your Product Promise”:

“As recent headlines attest, the financial cost of product failure can have a major impact on a company’s bottom line – eroding current profit margins and impacting future financial as potential warranty costs are built into the forecast. There are other long-term costs of product failures that may be less tangible but equally important.  Today, thanks to the expansion of social media, a single dissatisfied customer can share his or her views with the world in seconds, via a single mouse click.  Though harder to measure than warranty costs, negative product reviews can cause irrevocable damage to any manufacturer’s hard-won brand equity.”

Costs of product failures total much more than just the part value. Customer relationships are the strongest foundation for a business, and one area in which LSP Technologies places heavy emphasis.  If you’re in need of product life enhancement, contact us to discuss how we can help you and your customers.

From the article “Robust Design at Pratt & Whitney”:

“Many components of jet engines require cast materials with long lead times.  This results in the need to design parts and commit to geometry long before thermal boundary conditions are measured, so these designs need to be robust across a range of potential thermal conditions.”

One of the major points here is that shortened product development cycles can occasionally result in design deficiencies. Situations like this have occurred countless times in the past, and laser peening has been recognized as a solution to treat critical areas that do not perform as intended.  Laser peening often enables these products to meet and exceed their original design requirements.

 

Whether you are looking at new designs that stand to benefit from laser peening, or you’re looking to improve upon your current product line, laser peening presents a great opportunity to increase your product reliability.  Give us a call to discuss your application!

 


Literature Review II

As an active member in the surface modification field, LSPT routinely reviews technical papers published on surface modification technologies.  To share some of the information that is currently available in the community with our customers, we are continuing a website feature where we review a published article from the array of journals available and note a few key items.

The paper up for review this week is titled “Healing fatigue damage by laser shock peening for copper film.”  by X. Liu et al.  The article is available for purchase at http://www.sciencedirect.com/science/article/pii/S0142112313000923.  Several images and the abstract can also be reviewed.

The authors investigate the use of an excimer laser in laser peening copper films targeted to the MEMS (Micro-Electro-Mechanical Systems) industry.  Studies are made of both how laser peening improves the material properties over baselines values and also how laser peening after cyclic loading allows the material to have a longer total life than the undamaged laser peened samples.  This effect is what the authors refer to as the healing effect.

This article offers an interesting read for those in the MEMS industry and offers another great example of the benefits of laser shock peening, especially in new applications!
