Differences Between Forged vs Other Bars

December 10, 2013

Edward Vojcak P.E. was a colleague in the Technical Services Department at Bliss and Laughlin Steel, a cold finisher on Chicago’s South Side.

Today he is a Metallurgist and Professional Engineer with A. Finkl and Sons Co.  in Chicago, as well as  a leading contributor to LinkedIn’s Metallurgy and Material Science Group.

I was impressed with  his response to a  recent request on LinkedIn asking “Why are forged bars better than other bars for a piping application?”

Here is Ed’s reply:

“”Better” is relative.  Best practice is to optimize cost, time and quality of performance.  Forgings are typically more expensive than bar stock or castings because machined dies and furnaces are required – they are generally tougher because the deformation re-aligns the ever present non-metallic inclusions in metals parallel to applied stress – hence the improved quality.  Bar stock can be machined into almost any configuration quickly and has most of the directional strength along its length.”

There are a lot of takeaways from this succinct paragraph, but the one I thought the greatest takeaway was this:

“Better” is relative.  Best practice is to optimize cost, time and quality of performance.

Best practice is

  • Not to optimize only cost.
  • Not to optimize only on quality of performance.
  • Not to optimize only for time.

Ed’s statement gets to the crucial issue in selecting materials for manufacturing- selecting to optimize for several key issues.

Not just raw materials cost.

Thanks  Ed Vojcak for the share.

Shadow Boards: Pride and Professionalism

November 26, 2013

“Setups are going a little smoother (mostly);  there is much less wasted time searching for
needed tools; and everyone is showing a little more pride and professionalism
in their tidy new professional  work area.”

Avoiding unneeded tools is just as important as having the ones you need.

Avoiding unneeded tools is just as important as having the ones you need.

PMPA Vice President Tom Bernstein  of Torin Products, a CNC Swiss shop in Columbus Nebraska just shared his experience with Shadow Boards in  the December issue of Production Machining Magazine.

Its an easy read, and it tells as good a story about how to manage as it does about how to create Shadow Boards.

“The benefits are not just financial and measured in saved time. My team is now confident that in this area they exemplify Best Practice.”

File this one under continuous improvement! Read the full story here

2 Rules For Effective Benchmarking

August 6, 2009

Benchmarking is not a comparison of numbers or indicators. Benchmarking is an ACTIVITY or PROCESS to determine Best Practice, and your relationship to that Best Practice.

Benchmarking is an activity that employs a systematic and continuous effort to identify important measureables (benchmarks). It  employs a defined process to compare your organization’s status to that of a best-in-class company or companies. Benchmarking is a tool that helps you identify, improve and implement the practices or methods that will enable you to become the new ‘best-in-class.’

Two rules for effective Benchmarking are:

  1. If Benchmarking does not lead to a specific action, it is a waste of your company’s resources;
  2. If you aren’t Benchmarking to the best, your Benchmarking will be under effective.

Competitive analysis can tell you what the differences are between you and another company, but it does not give you any insight into how that difference exists. Benchmarking focuses on best practices and methods, resulting in process changes and improvements that will achieve improved customer satisfaction.

Site visits in my experience result in some limited information sharing and collection of novel ideas, but  after the visit, these are recognized to be a smorgasbord of unfocused facts. While these facts may be interesting, they may or may not be applicable to your firm or what you are trying to accomplish. This is especially true if the facility that you are visiting is not a best in class peer.

PMPA members have a Benchmarking ‘tool they can use’ to measure their company’s performance against their peers in manufacturing.

PMPA's iLumen Benchmarking Service is secure and easy to use.

PMPA's iLumen Benchmarking Service is secure and easy to use.

Called PMPA iLumen Benchmarking Service, this safe, secure online tool allows participating members to compare their company’s financial and operating performance against that of their peers or other manufacturing companies. Seeing the difference between their firm’s and other firms’ performance in key areas  gives the PMPA members a focus for their company’s improvement activities.

In the April Issue of PMPA’s Business Trends Report,  almost half of the companies  that reported double digit sales increases over the prior month were PMPA iLumen Benchmark participants.These companies have used the intelligence of the PMPA iLumen Benchmarking data to show them where to address improvements in their organization.

Participation in PMPA iLumen Benchmarking is no extra charge for PMPA members- it is a member benefit.

Numbers may be the language of Benchmarking, but they are merely raw material that drives the real activity- continuous improvement and transformation of your people, processes, and systems. These improvements will result in higher quality, lower costs, and ultimately, improvement of your company’s products and services. PMPA’s iLumen Benchmarking Service can provide you too, with “tools you can use” to drive improvements in your companies processes and performance.
