Grounding Strap Assembly

Project description: Grounding Strap used in railroad application
With our depth of expertise and efficient methods for product manufacturing and assembly, Penn Metal Stamping, Inc. provides cost-conscious solutions that effectively compete with prices from offshore vendors. Also, by being in close proximity to a client, we can easily collaborate with their internal teams on design issues. We are often able to make recommendations that improve quality and manufacturability while significantly trimming production timelines.
The railroad grounding strap shown here consists of two stamped metal terminals, tin plated copper wire braided cable, and black tubular insulation. While reviewing the drawing, we identified that altering a few design elements would improve the overall quality of the product while facilitating manufacturing and assembly. The client was very pleased with our recommendations and price so they awarded us the contract.
Production involved several coordinated process flows. Along with cutting the wire and insulation to size, we proceeded with the tooling and stamping of the metal terminals. The manufactured components converged into the assembly area, where our press operators joined the four pieces into a finished ground strap assembly measuring 5.0" in length. In addition to in-process inspection of the individual parts, we pull-tested the finished straps to ensure their strength and functional integrity.
One extremely favorable aspect for the client was the short amount of time it took us to complete this project. Our comprehensive capabilities allowed us to deliver a moderate volume of product to them within a one-week turnaround, substantially faster than an overseas vendor would have accomplished. The client was very impressed with the results, and we were pleased to acquire a new and satisfied client.

Retainer Plate

  • Project Name & Description Retainer Plate
  • Material Used Steel
  • Volume High
  • Tightest Tolerances ± .0015"
Project description: Retainer Plate used in automotive transmission
At Penn Metal Stamping, Inc., manufacturing, inspection, and assembly of critical parts for the automotive industry is one of our core strengths. We have an in-depth understanding of the production part approval process (PPAP) and the important role it plays when doing business with this industry. Our familiarity with the process allows us to cost-effectively compete with larger suppliers while offering the level of prompt, reliable, and personalized service that as a small business we excel at providing.
We manufactured the transmission retainer plate components shown here for a major automotive company. These parts had very detailed features that we needed to reproduce accurately and repeatably in thick gauge materials. The ingenuity of our design engineers allowed us to develop unique, non-standard tooling and fixturing that enabled us to overcome the difficulties associated with stamping geometrically complex shapes. Constructed from steel, we were able to uphold tolerances as close as .0015" on all dimensional aspects, including flatness. Our production process also involved deburring to remove any shards remaining after the stamping process and improve the quality of the finished part.
Quality assurance is a dominant activity in our shop. From the sheet metal that came in the door, to die manufacture and upkeep, press maintenance, and process controls, we built quality into every aspect of this stamping process. We prepared all the required PPAP documentation and applied a rust preventive coating on the retainer plate components to protect them during shipping and storage.

Custom Aluminum Stamping

  • Project Name & Description Aluminum Cap
  • Overall Part Dimensions 1 ½" x 1" x .010"
  • Volume High
Project description: Aluminum Cap used in steering system
The aluminum cap highlighted here is an example of a product we produced in high volume here at Penn Metal Stamping, Inc. Used as a component in an automotive steering system, it features close tolerance, thin gauge construction. One of our challenges for this project was developing packaging to protect the cap during overseas shipment to China.
Due to the size and shape of the component, we ran several prototype runs to ensure the stability of our process and to validate that the product conformed to specification. Production involved deep draw stamping combined with a pinch trim cut-off to provide a clean surface on the open end. When completed, the housing featured dimensions of 1.5" in length x 1.0" in diameter x 0.010" in thickness. Our quality assurance procedures involved dimensional gauging to ensure we accurately and repeatably met the tight .0015" tolerance requirement for this high volume application.
The narrow gauge construction of these parts made them very fragile. We designed a custom method for packaging these items to achieve two goals. One was to protect them during transport; the other was to optimize the packing density for cost-effective bulk shipment overseas. Although we are a small business in Pennsylvania, the quality of our work has earned us an international reputation, so we are familiar with all of the process and paperwork involved with worldwide freight handling. The aluminum housings arrived safely at their destination in China, and the client was very satisfied with the quality and timeliness.

Helical Gear Assembly

  • Project Name & Description Assemble two steel flanges to end of helical pulley gear through the material displacement process.
  • Material Used 1020 CRS
  • Volume 700, 000/year
The helical gear assembly highlighted on this page was produced completely here at Penn Metal Stamping, Inc. For this project, the client supplied the pulley while we were responsible for manufacturing the flanges and assembling the final product.
We stamped the flanges from carbon steel, which provided the high strength properties required while being ductile enough to be reformed during assembly without losing its toughness. Assembly involved joining one of these steel flanges to each end of the supplied helical pulley gear, which was manufactured from powdered metal. Our engineers developed a method to do this using innovative tooling and a material displacement process on the assembly press. This swaging process allowed us to alter the diameter just enough to form a permanent fit of the metal components. We used an advanced technology control and monitoring system on the assembly press to ensure that the stroke forces were consistent over the entire production run and from lot to lot.
Once we assembled the components, further quality assurance involved various inspections to ensure tolerances were within .002". We also physically pulled apart samples of the finished product to measure the forces needed to break the strength of the bond. This destructive-type testing gave the client confidence that the products would perform as intended and avoid the possibility of in-field failures. Prior to shipment, we applied a dry-to-the-touch rust inhibitor to protect them during transport and storage.
We produce these parts at the rate of 700, 000 per year, in batches that we turn around on a two-day basis, and the client has since rewarded us with additional business.

Weld Fixture

  • Project Name & Description Weld Fixtures
  • Material Used Copper
  • Volume Low
Project description: Design and build weld fixtures for customers
The tool shop in our facility here at Penn Metal Stamping, Inc. is a busy operation. In addition to building dies and fixtures for our own internal use, we build and repair tools for outside clients. Designing and building tools and fixtures is a complex process that is managed by a group of individuals with a broad skill set. They use sophisticated software programs to design, refine, and validate functionality, and then use many different types of machines and other equipment to reproduce their designs in metal. Since tools and fixtures typically have very close tolerance requirements, the process of machining, measurement, and inspection is done with diligence and attention to detail.
The weld fixture shown here is an example of one such project we recently completed in our tool shop. Designed for use on an electrode-welding machine, it featured copper construction to promote welding stability. No detail was overlooked during the design phase to ensure the fixture would allow for repeatable accuracy at maximum production rates. We also designed and built this fixture to withstand prolonged stress with minimal maintenance requirements.
Our technicians use our high-tech machining center, wire EDM, and soldering equipment to build and assemble the fixture. When complete, the main body measured 2.0" in length x 2.0" in width. In addition to numerous in-process inspections, we performed a leak test to ensure the fixture was fully sealed.
Through the efforts of our engineering team, tool shop technicians, and quality analysts, we manufactured a single version of this fixture within a very short two-week timeline. Feedback from the customer has been exceptionally positive.
