Excellence in Product Development
Pridgeon & Clay
Pridgeon & Clay, Inc., Grand Rapids, MI, received the 2012 Ulbrich Award for Competitive Excellence in Product Development for its stamped bearing bracket. The firm, a value‐added manufacturer of stamped and fineblanked parts for the automotive industry, approached its customer, NTN Bearing Corporation, with the improved design for the bearing bracket, originally cast and machined to maintain tolerances of 30 microns. To reduce part weight and cost, in 2011 the OEM customer submitted an RFQ. Every supplier except for Pridgeon & Clay no-quoted the job. Part volume: 31,500
NTN already had a part design being produced overseas comprising a stamped bracket that required machining after stamping Instead, Pridgeon & Clay proposed the switch to a progressive stamping of 5-mm-thick stainless steel, which included trim operations to eliminate machining. Key to the success of the project was proving to its customer that the existing design and processes were capable of holding the required tolerances. Pridgeon & Clay and NTN engineers developed tolerance requirements that could be met in a stamped part. They also determined the effects of parts significantly out of round and tolerance, concerned about the impact on bearing life. They found that the stamped part exhibited greater elasticity than expected—the material flexed to accept the bearing, rather than crack as would a cast metal part.
Pridgeon & Clay’s tooling engineers ultimately determined that a 16-station progressive die, run in its 1250-ton press, could hold the required part tolerances. Moving from a cast part to a stamped design removed more than $8 from the cost of each CV-joint assembly. In addition, the design change resulted in significant weight savings for the OEM.
The Product Development Award, sponsored by Ulbrich Stainless Steels and Special Metals, Inc., North Haven, CT, acknowledges a manufacturing company that demonstrates outstanding innovation in developing and manufacturing a product that best uses metal in place of a nonmetal competitive material, or that develops a product using flat-rolled material that was previously manufactured using more costly manufacturing processes.
Excellence in Quality
Pridgeon & Clay
Pridgeon & Clay also received the 2012 Waukesha Metal Products Excellence in Quality Award, for introducing several programs surrounding quality metrics, including development of scorecards used to highlight key metrics in each area of its business. The firm’s quality department tracks progress on the scorecard, which is reviewed monthly by top management.
The Pridgeon & Clay quality department streamlined its gauge-planning process in 2010 and enjoyed a 50-percent reduction in the cost of gauge changes. In 2011 the group challenged itself to make another significant improvement, and did so by developing a new document called a Preliminary Dimensional Plan. It’s used to provide the gauge shop with a specific outline of its requirements, mirroring the control plan and supporting the inspection checklist used by production personnel.
In addition, during the past year Pridgeon & Clay’s customers required annual validations on all service parts, above and beyond their written manuals. This led the company to review its labor and machine resources. As a result, it adjusted its gauge-technician staff to allow CMM work on third shift, reviewed production-CMM programs being run for ongoing capability studies and incorporated dimensional reports into its validation program.
Pridgeon & Clay also introduced several new products in 2011-2012 with extremely tight tolerances, which required the addition of new measurement equipment. The company integrated a new scope to check for chamfers, radii, small teeth and centers of arcs, and a multisensory vision system to inspect fuel-cell components. It’s also evaluating the addition of portable gauging machines (Renishaw Equator models, described as an alternative to custom gauging) to replace CMMs on the production floor. And it’s closely monitoring and addressing CMM-related production-downtime events.
With the close monitoring and effective action plans related to metrics, Pridgeon & Clay has set a goal of getting its PPAP records 100-percent complaint to customer requirements, and has improved to 95 percent, compared to 88 percent previously.
The Quality Award, sponsored by Waukesha Metal Products, Sussex, WI, recognizes outstanding achievement by a manufacturing company in the development and implementation of a company-wide quality system that effectively uses continuous improvement.
Excellence in Productivity
Eclipse Manufacturing Company, Sheboygan, WI, received the 2012 Zierick Manufacturing Corporation Productivity Award. Eclipse, a contract manufacturer of stamped and welded assemblies serving the small gas engine, automotive and other markets, won the award for incorporating a robotic-welding cell to assemble fan housings. The project resulted in dramatic productivity improvements.
Due to volume limitations, the original manufacturing plan was to stamp the housing components and assemble parts using manual spot-welding machines. Eclipse was able to justify assembly with a robotic-welding cell when it received additional orders for engine-housing assemblies. Each housing comprises two or three unique baffle components with seven to nine weld nuts.
The robotic-welding cell as-designed was budgeted to cost the same as three sets of manual spot-welding fixtures. The custom cell features powered and free conveying equipment. One conveyor can load six sets of components on pallets (shown below), while six fan-housing stampings on pallets move on a second powered conveyor. The conveyors automatically transport the housings and the internal components into the welding cell.
The cell employs three robots—two handling robots and one welding robot —as well as a nut welder. The nuts are welded to the housing before the housing passes to the handling robot for locating in a weld fixture. Part-presence and motion sensors track all parts and automated motions, and tool positions. The composite cycle time for the weld cell averages 100 sec. Welding time for one housing type has been reduced by 53 percent, while production volume has increased by 30 percent.
Overall savings for the three housings being welded in the cell is estimated at 1.2 man-years compared to manual spot welding. The weld cell was used to provide a 10-percent cost savings to the customer. As a result of the increased scheduling flexibility provided by the robotic-welding cell, Eclipse earned a Supplier of the Year Award for Customer Service at its customer’s annual supplier conference held in April 2012.
The Productivity Award, sponsored by Zierick Manufacturing Corp., Mount Kisco, NY, recognizes outstanding achievement by a manufacturing company in the development and implementation of programs, processes and use of assets that lead to significant improvements in productivity.
Excellence in Safety
Unirac Inc., Albuquerque, NM, received the 2012 Pitcher Insurance Agency Safety Award, for its outstanding employee-driven safety and health program responsible for achieving more than three years of injury-free performance. Employing 140 people, Unirac designs, manufactures, distributes and installs photovoltaic solar-industry mounting structures.
By using a “from the ground up” approach versus a “top down” management mandate to improve its safety performance, the company has achieved full-scale buy-in from its operators who self-monitor workcell activities, develop safe work practices and enhance material-handling procedures. With the many pieces of equipment employed at the company, the handling of 4000-lb. bundles of raw material via forklifts and a fast-paced environment, the employees’ commitment to safety is evident. In January 2012, Unirac had a surprise OSHA audit with no findings.
Select portions of Unirac’s safety program include program oversight and administration at the COO level; use of daily, weekly and monthly safety checklists and data collection that drive safety metrics and KPIs; a documented process to evaluate accidents, incidents and near misses as a means of root-cause and corrective-action efforts; and an employee-run safety team with management involvement and commitment to support the team in implementing their recommendations.
As part of the safety program, safety audits are conducted across the factory using “new sets of eyes” from outside the audited area to look for safety concerns that may be overlooked by those who work there every day. Opportunities for improvement are posted and the implementation of the recommendations tracked. In addition, spot awards and employee-of-the-month recognition for self-directed safety-related actions are provided, and employees’ safety efforts are recognized in the company’s pay-for-performance bonus program. Unirac continues its commitment to world-class operational practices with its pursuit of OHS 18001, Occupational Health and Safety Management Systems certification, anticipated by the end of 2012.
The Safety Award, sponsored by Pitcher Insurance Agency, Chicago, IL, acknowledges either an effective comprehensive safety program or a specific innovative idea in the context of an effective safety program.

Excellence as an Educational Institution
Orleans/Niagara Career and Technical Education Center (OCTEC)
OCTEC, Medina, NY, received the 2012 Clips & Clamps Industries Educational Institution Award for its outstanding Precision Machine Technology (PMT) program. Under the direction of instructor William Rakonczay, the primary focus of the program is “jobs, jobs and jobs.” Students—currently 24 seniors and 25 juniors—come to OCTEC at the beginning of their junior year. By the end of their senior year, they are expected to be ready for the workforce with, at the very least, good entry-level skills. The program is a mix of theory work and hands-on practice —roughly 2 hours of practical work per hour of classroom instruction. In addition to technical knowledge and practical skills, students must demonstrate organizational skills, responsibility, good attendance, a positive work ethic and all of the attributes that make a good employee.
More than 50 percent of the students in the class achieve National Institute of Metalworking Skills (NIMS) certification each year. The OCTEC PMT program is the only secondary program in New York certified by NIMS. Articulation agreements also have been forged with Erie Community College, Monroe Community College and Genesee Community College, through which students may choose to earn college credits.
Successful students are rewarded by working in “capstone” placements at local companies. Seventy-five percent of seniors are successfully placed in work-study programs each year. In addition, this summer five juniors worked in internships at local companies and were part of OCTEC’s fall co-op program.
The Educational Institution Award, sponsored by Clips & Clamps Industries, Plymouth, MI, recognizes a public or private educational institution that provides outstanding training and education services to companies in the metalforming industry. The award is funded by the Dul Foundation. MF
