Case Study: Achieving Cosmetic Standards in the Stamping Press Customer’s Goals Select a tooling shop that could design and build a progressive stamping die of this magnitude. Select a metal stamping supplier with the capability and capacity to produce these larger-sized, highly cosmetic side tables. Design and Manufacturing Process Customer Ultra designed and built a 144-inch progressive stamping die equipped with multiple stations and in-die sensors to produce the Major Appliance Manufacturer side table on our 800-ton press. The part's stringent cosmetic standards made it a challenge to metal stamp and this case Part study outlines how we established a successful production process. Stainless Steel Side Tables To remove sharp edges on the side table during metal stamping the Die Manufacturing Issue Designers utilized two methods; hemming and coining. Hemming Utilizing their own equipment and works better on longer, straighter edges and so this method is primarily employees to produce this part was applied on the side edges of the tables. Hemming precisely wraps the sheet not sustainable for the long-term. metal back around itself and forms a clean, radius edge. Coining operations are then used to remove the sharp edges on the remaining areas of the side table including interior locations; resulting in a stamped cut edge. Another key component to maintaining the cosmetic standards was locating a steel supplier that could provide plastic coating on one-side of the sheet metal and within the specified material thickness. Finally, during metal stamping two methods are utilized to maintain clean surfaces on the side tables. One is a permanent sprayer attached to the progressive die that clears away plastic and metal shavings. Second, in the last station of the die is a vacuum-like operation to remove all remaining debris from the side table. VIEW THE LAST STAGES OF THIS PRODUCTION Achieving Cosmetic Standards in the Stamping Press Customer’s Outcome Side tables are being delivered defect-free for assembly at their manufacturing facility. Significant time and money are being saved utilizing Ultra as their all- inclusive supplier. We provide die design and tool building, metal stamping, packaging and die maintenance services. .

Integrating Cold Forging and Progressive Stamping for Cost
Precision Cold Forging Progressive Stamping Enables Cost Effective Production of Complex Parts Overview Both Cold Forging and Precision Stamping are proven technologies used in the fabrication of parts for a wide range of industries. Many of our previous Tech Bulletins have detailed the benefits of each technology, and in several cases, these processes are thought of as an either- or choice. This Tech Bulletin provides insights into how combining these technologies in a process known as Precision Cold Forging Progressive Stamping can provide significant synergies and additional benefits for the cost-effective production of complex parts that cannot easily be created by either technique alone. What is Cold Forging? As detailed in other Interplex Tech Bulletins, Cold Forging is essentially an impact forming process in which billets of raw material are compressed and reformed into a part’s desired shape. Cold Forging offers the key benefits of lower costs, rapid high-volume throughput, high part strength, and very efficient material utilization. This, in comparison to processes like machining that remove Figure 1 – Cold Forged significant amounts of raw material rather than simply reforming all the Automotive Seat Belt Gear material into the desired shape. What is Precision Stamping? Precision Stamping is another proven technology that uses a press and die to form sheet metal, blanks or coil material into desired shapes. Variations of the stamping process can effectively yield several different output results including bending, embossing, flanging, coining, etc. Like Cold Forging, Precision Stamping typically offers high material utilization with minimal waste and can also deliver high-volume production results.

Progressive Stampings
Perfection Spring and Stamping Corp. Defining What We Do…. Progressive Stampings Progressive (punch and blanking) die with strip and punchings. Progressive stamping is a metalworking method that can encompass punching, coining, bending and several other ways of modifying metal raw material, combined with an automatic feeding system. The feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. The carrying web, along with metal that is punched away in previous operations, is treated as scrap metal. The progressive stamping die is placed into a reciprocating stamping press. As the press moves up, the top die moves with it, which allows the material to feed. When the press moves down, the die closes and performs the stamping operation. With each stroke of the press, a completed part is removed from the die. Since additional work is done in each "station" of the die, it is important that the strip be advanced very precisely so that it aligns within a few thousandths of an inch as it moves from station to station. Bullet shaped or conical "pilots" enter previously pierced round holes in the strip to assure this alignment since the feeding mechanism usually cannot provide the necessary precision in feed length. The dies are usually made of tool steel to withstand the high shock loading involved, retain the necessary sharp cutting edge, and resist the abrasive forces involved.

Sorting of Automotive Manufacturing Wrought Aluminum Scrap
Sorting of Automotive Manufacturing Wrought Aluminum Scrap A Major Qualifying Project Submitted to the Faculty of Worcester Polytechnic Institute in partial fulfillment of the requirements for the Degree in Bachelor of Science in Mechanical Engineering By Shady J. Zummar Ghazaleh Date: 04/26/2018 Sponsoring Organization: Metal Processing Institute Approved by: ________________________________________ Professor Diran Apelian Alcoa-Howmet Professor of Engineering, Advisor Founding Director of Metal Processing Institute Abstract An increase of 250% in wrought aluminum usage in automotive manufacturing is expected by 2020. Consequently, the generation of new aluminum sheet scrap will also increase. Producing secondary aluminum only emits 5% of the CO2 compared to primary aluminum – a significant 95% decrease. With the advent of opto-electronic sorting technologies, recovery and reuse of new aluminum scrap (generated during manufacturing) is at hand. A series of interviews with industrial experts and visits to automotive stamping plants were performed in order to identify: (i) the most common wrought aluminum alloys from which scrap is generated; (ii) the present scenario — how scrap is collected today; and (iii) the types of contamination that must be accounted for during and after sortation. Recommendations are made herein that will support the development of an optimized scrap management system including sorting criteria that will enable closed loop recycling. 2 Table of Contents Abstract 2 Table of Contents 3 Acknowledgements 5 1 Introduction

Improvement in the Forming Process of Support Brackets Vulnerable to Cracking
Improvement in the forming process of support brackets vulnerable to cracking - problem solving in the field of sheet metal forming Examensarbete Materialvetenskap Martin Lind Date: 2012-10-04 DEGREE PROJECT Metals working engineering Programme Extent Materials Design and Engineering, 300 ECTS 30 ECTS Name of student Year-Month-Day Martin Lind 2012-10-04 Supervisor Examiner Lars Troive Stefan Jonsson Company/Department Supervisor at the Company/Department Schneider Electric – Wibe, AB Annarella Jansson Title Improvement in the forming process of support brackets vulnerable to cracking Keywords Sheet metal forming, forming methods, flanging test, cracking, FEA, galling Summary This report has been written to summarize my work, regarding a will to improve the manufacturing process of a support bracket used for cable ladders. The company concerned in the project have experienced several problems with severe cracking in a flange radius throughout the years of production. The main task has therefore been to identify the problem and to come up with some suggestions of how to avoid these issues ahead. In order to evaluate the formability of the material used in production, flanging tests have been performed accompanied by finite element analysis in MSC Marc. The conditions of the cut edge subjected to cracking, as well as the cutting tool, have also been investigated by light optical microscopy (LOM), as well as by scanning electron microscopy (SEM). The results show that the flanging operation in today's production of support brackets extensively exceeds the critical flanging ratio of the steel sheet material. As sheet material tends to adhere to the tool surfaces, issues due to galling can also be stated during manufacturing.
