August 2017 | Craftsman’s Cribsheet #57 Failures of steel parts in service or production occur infrequently. However, when steel parts fail, the consequences are dire. Here are seven ways that steel can fail as a result of quench cracking from heat treatment. VIEW/DOWNLOAD
July 2017 | Craftsman’s Cribsheet #56 “Stress cracks are defined as transverse or near transverse open crevices created when concentration of residual stresses exceed the local yield strength at the temperature of crack formation. These stresses can be mechanically induced or attributable to extreme temperature differences and /or phase transformations. They can originate at…
June 2017 | Craftsman’s Cribsheet #55 In “The Toyota Way,” author Jeffrey Liker lists and discusses the eight non-value-adding wastes that can be found in business and manufacturing processes. These can be applied anywhere, not just on a production line. Here is a look at these wastes through the lens of our precision machining…
May 2017 | Craftsman’s Cribsheet #54 We all know the importance of safety in our shops, so here are 12 simple rules to help eliminate accidents and injuries in the workplace: VIEW/DOWNLOAD
Business Disaster Recovery Plan for PMPA Members To help member companies serve their customers and to minimize any interruption of service, PMPA has developed a Disaster Recovery Plan Procedure. The Procedure will assist PMPA member companies facing unplanned disasters such as tornados, fires, flooding, etc. to provide means to keep the supply of critical…
April 2017 | Craftsman’s Cribsheet #53 Unleaded brasses are not necessarily harder to run than leaded brass. They are just different. VIEW/DOWNLOAD
March 2017 | Craftsman’s Cribsheet #52 In cold worked steels, failures can be broadly nucleated by localized defects, such as seams, pipe and exogenous inclusions. The second are those which result from exceeding the strength of the material itself. VIEW/DOWNLOAD
Status Report on RoHS Leaded Materials – January 10, 2017 The European Commission is almost a year late on providing their decisions on the RoHS exemptions that affect our industry. The attached report will help you make sense of the review on exemptions for lead in Steel (6a.), Aluminum (6b.), and Brass (6c.) as…

November 2016 | Craftsman’s Cribsheet #50 The ability of a material to deform plastically without fracturing is called ductility. In the materials usually machined in our shops, ductility is measured by determining the percent of elongation and the percent reduction of area on a specimen during a tensile test. VIEW/DOWNLOAD
