     The Group Leadership Team (GLT) of the Milwaukee Section of ASME consists of ten (10) elected members:  chair, vice-chair, secretary, treasurer, and six (6) advisors.  This year, we will be voting for all 10 positions as required by the new ASME directives.

     The Nominating Committee, consisting of Ken Derra, Joe Derra, and Bob Stachowicz, propose the following ASME members be elected to the following Milwaukee Section Group Leadership Team positions.  

     Chair: Allen Perkins - Allen currently serves as Chair.  After leaving the Navy in 1972, he joined his father’s business, Perkins Engineering Co.  He has held a PE since 1977, is still running the company, and considers himself semi-retired.

    Vice-Chair:  Scott Kramer - Scott currently serves as Secretary.  He received a Bachelor of Science in Mechanical Engineering in 1984 from Northwestern University and a Master of Science in Mechanical Engineering in 1992 from UWM.  Scott has been employed by Milwaukee Electric Tool, since 1993, and currently leads and manages many of the lithium ion battery projects.

    Secretary:  Liam Coen - Liam currently serves as an Advisor.  He is a Lead Engineer at GE Waukesha Gas Engines, and presently a member of the American Gear Manufacturers Association (AGMA) Materials and Metallurgy Committee.

    Treasurer:  Douglas KieslingDouglas currently serves as Treasurer.  He has a Bachelor of Science in Applied Mathematics and a Master of Science in Mechanical Engineering.  He currently works for GE Waukesha Gas Engines.  In 2009, he host-chaired the Spring Conference for the Internal Combustion Engine Division of ASME at Waukesha Engine.

    Advisor:  Bryan EskraBryan currently serves as an Advisor.  He received a Bachelor of Science in Mechanical Engineering, emphasizing Energy Conversion, from UWM in 1970.  He is a registered Professional Engineer in 6 states, including Wisconsin.  Bryan is a Life Member of ASME and has been active in our local section.  He was Vice-President, Principle, of Power Engineers Collaborative, LLC.

    Advisor:  Gene JanikowskiGene currently serves as Vice-Chair and has been an ASME member since 1975 and is a Life Member.  He is a Registered PE in Wisconsin, an ISO 9000 Auditor, and a Six Sigma Blackbelt.  He is retired from C&D Technologies.

    Advisor:  Subha KumpatySubha currently serves as an Advisor and has coordinated the Section’s efforts in educational seminars.  Since 1997, he has taught at MSOE and currently is a professor of mechanical engineering and the program director of the Master of Science in Engineering program.

    Advisor:  Chris NelsonChris is seeking his first position on the GLT.  He has been an active member of our section.  He works at GE Waukesha Gas Engines.

    Advisor:  Carissa PetzingerCarissa currently serves as an Advisor.  She received a Bachelor of Science in Mechanical Engineering with a minor in Electrical Engineering in 2013 from Marquette University.  Carissa was very active in Marquette’s ASME section and was Vice-Chair of District Events for the Student District Operating Board (SDOB) for District C from 2010 to 2013.  Currently, she is on the College Relations Committee for our section and works at Generac.

    Advisor:  Buck TannerBuck currently serves as an Advisor and has been an active member for the last few years and most recently he has been involved with the meeting arrangements committee.

  • History and Heritage Event - May 18, 2016

    This month, the ASME Milwaukee Section is inviting you to join us at the Grohmann Museum at MSOE for a presentation by Tom Fehring, the chairman of ASME’s history and heritage committee.  Tom will discuss Milwaukee’s industrial heritage.  Tom has been researching the mechanical engineering accomplishments of Milwaukee-area companies since 1980 and has recently begun writing a book on the subject.

    Before the presentation, there will be a brief meeting including elections of officers for our Group Leadership Team (GLT) as well as Honors and awards.  This will all follow a Dinner Buffet  that will include roast beef and orange roughy.

    For more information and a complete list of the individuals being elected to the GLT, AND also to register for this event please click on the following link:

  • Tour of Signicast Corporation--Hartford, WI

         On Wednesday, March 23, 2016, our annual combined ASME/SAE tour was held at Signicast Corporation in Hartford.  This year, the tour was organized and planned by SAE.  Just over eighty members toured the highly automated, state of the art facility that produces quality investment castings.

              As our group toured the plant, the guide described in detail the steps involved to produce investment castings:

    1. Creation of prototype parts—3D additive manufacturing is used to create the initial wax patterns.  Sample parts are then poured and inspection by CMM is used to verify the customer’s dimensions.
    2. Manufacture of production tooling— Several large six axis CNC machines provide in-house capability to produce the large tools for injection molding of the wax patterns.  Programming is performed in a separate area.  Tool room machinists then assemble the components.  No blueprints are used on the shop floor--computer workstations provide access to all drawings.  With the abundance of software, computers and robots, software licensing becomes a major expense.
    3. Injection molding of wax patterns--The patterns are molded similar to the injection molding of plastic parts.  Parts are then automatically unloaded and placed on conveyor systems.
    4. Assembly of patterns to sprues forming clusters—  Multiple wax patterns are assembled into one complex pattern and attached to a wax sprue with the result known as a pattern cluster, or tree.
    5. Dipping of assembly into slurry by robots— The first step (priming) is to dip the pattern clusters into a solution of fine refractory material with excess material allowed to drain off.  The next dip involves a (stucco) coarse ceramic particle slurry.  Other dipping operations may be used, and, robots perform the planned sequences.  The slurries consist of common refractory materials such as silica, zircon, aluminum silicates and alumina.  We were allowed to feel these slurries—this was a hands on/in tour.
    6. Drying/Dewax-- The coating is now allowed to thoroughly dry which can take 16-48 hours.  The molds are then turned upside down and placed in a furnace to melt and vaporize the wax patterns.  It should be noted that the mold must be strong enough to withstand the pouring and dewaxing heat and pressures, but not so strong that it is difficult to remove the ceramic mold after pouring.
    7. Burnout and preheating.  The mold is then subject to a burnout which heats the mold and removes moisture and residual wax.  The mold is then preheated to allow the metal to stay liquid longer to fill in any details.
    8. Pouring operation--  Liquid metal is then poured into the mold, either by robot or by hand.
    9. Divesting--  The shell is then removed by pressure and media blasting.  Rough and final finishing removes the sprues and cleans up the casting.                                                                                                                                                                                                                   As we toured the factory, the level of automation was impressive.  ASME Magazine recently reported that by 2025, over 45% of factory jobs will be automated.  With Signicast’s high level of automation, driverless vehicles and automated material handling resulted in a minimum of workers visible throughout our tour.                                                                                                                                                         With over eight hundred workers, forty some engineers and five foundries, all working together, Signicast is a leader in the manufacture of investment castings.  We thank the management and tour guides for their time and expertise to present a quality tour.
