  • The Lost-Wax Casting Process—Down to Basics by Eddie Bell, Founder, Santa Fe Symposium
    The Lost-Wax Casting Process—Down To Basics By Eddie Bell, Founder, Santa Fe Symposium. Lost-wax casting is a ancient technique that is used today in essentially the same manner as it was first used more than 5,000 years ago. As they say, there's no messing with success. Today, of course, technology has vastly expanded the technique and produced powerful equipment that makes the process faster, easier and more productive than ever, but the basic steps remain the same. The steps below represent a simple overview and are intended to provide a beginning understanding of the casting process. Concept This is obviously where the design is initally conceived, discussed,evolved, and captured on paper—or on computer; CAD (computer aided design) software is increasingly popular among designers. You create the design you envision using the computer tool and the software creates a file that can be uploaded into a CNC mill or 3D printer. Model Build a model, either by hand-carving, guided by the paper rendering, or by uploading the CAD file into a computer controlled milling machine or a 3D printing machine. Models are made using carving wax, resin or similar material. This process can also be done in metal by a goldsmith or silversmith. Note: If a 3D printer or other rapid prototyping equipment is used, it is possible to skip the molding and wax-injection steps by using one of the resins that are specially made to go directly to the treeing process. Molding Create a mold from your master model, placing it in one of a variety of rubber or silicone materials, curing the material, then removing the model from the finished mold.

  • We Cover Your Infrastructure®
    MUNICIPAL AND CONSTRUCTION ACCESS SOLUTIONS CORPORATE CAPABILITIES WE COVER YOUR INFRASTRUCTURE ® A of Innovation Family TraditionEast Jordan Iron Works, Inc. has been a part of the East Jordan, Michigan, community for over 125 years. William E. Malpass and his father-in-law, Richard W. Round, established the foundry November 8, 1883, to service the area’s booming lumber industry. At the time, the foundry produced castings for machine parts, ship parts, agricultural uses, and eventually railroads. Soon after the company was founded, W.E. Malpass called upon his brother James, a journeyman machinist in England, to join the firm. When the lumbering era came to a close, EJIW expanded into new markets allowing continued success in changing times. The company shifted to the production of street castings, water works valves, and fire hydrants. In the 1920s and 30s William E. gradually transferred management to his three sons, William Henry “Will” Malpass, Richard Ward “Dick” Malpass, and Theodore Edward “Ted” Malpass. As technology advanced during the 1950s and 60s, the third generation of leadership emerged. Will’s son, W.E. “Bill” Malpass, and Ted’s son, F. Bruce Malpass, converted the foundry to a completely automated, high-pressure molding line known as the Taccone Line. The new highly sophisticated equipment maximized production capabilities for the foundry. Since the mid-1980s the business has been led by the fourth generation: Fred Malpass, son of Bill Malpass, and Tracy and Tad Malpass, sons of F. Bruce Malpass. They have trans- formed EJIW into an international leader of construction castings by modernizing its facili- ties, acquiring and establishing additional branch operations, and developing an umbrella of companies known as the EJ Group®.

  • An Example in Steel Casting the One Person Hitch Housing for the 2 ½ and 5 Ton Trucks
    An Example in Steel Casting The One Person Hitch Housing for the 2 ½ and 5 Ton Trucks The Application – The one person hitch housing is part of an improved hitch/frame design for the military’s 2½ and 5 ton trucks, used for towing weapons systems, cargo trailers, and other payloads. The hitch housing acts as an alignment and locking fixture for connecting the trailer tow hook to the truck tow bar. Through a redesign of the housing to provide lateral motion to the tow bar during hook-up, the new hitch permits one-person operation, reduces hitch-up time, and provides for safer handling. Hitch Housing Description The hitch housing assembly is attached to the truck frame. The towing draw bar moves within the assembly during hook-up, which permits the draw bar to “swing” laterally to align with the trailer tow bar. After the trailer is connected, the draw bar self-aligns and locks in the hitch housing for towing. 1 The Challenge The hitch housing has a plate geometry with vertical alignment bars and rib stiffeners. It weighs approximately 60 lbs with nominal dimensions of 18” x 20” x 5”. The housing is made with SC 8630 steel and sees loads as high at 15,000 lbs (for the 5 ton truck). The first prototypes of the hitch housing were fabricated steel assemblies, consisting of more than 35 pieces bolted and welded together. The assembly required 4-6 hours of alignment effort during installation. The projected production cost of the steel fabrication assembly was $5000 per unit.

  • 3.6 Naturally Pressurized Gating Systems in Investment Castings
    Naturally Pressurized Gating Systems in Investment Castings David Poweleit, Diana David - SFSA Rod Grozdanich - Spokane Industries Richard Hardin, Christoph Beckermann - University of Iowa Laura Bartlett - Missouri University of Science and Technology Robin Foley, John Griffin, Charles Monroe - University of Alabama at Birmingham Introduction Investment castinGs are commonly considered to have fewer issues with inclusions (reoxidation). On one hand, this seems counterintuitive Given that the pouring and gating for a typical investment castinG involves metal rapidly beinG poured down a lonG, large sprue (tree) and then oftentimes fillinG the mold cavity with additional “waterfalls”. Thus, it would seem that the increased opportunity for interaction between the molten steel and air would promote the formation of inclusions. That said, typical investment castinGs do offer some opportunities. Wall sections are generally thin and quick to solidify, which would limit time for inclusions to agglomerate and float up. In addition, the ceramic shell of an investment castinG is sintered and provides an inert atmosphere unlike sand castings where mold-metal reaction must be manaGed. Based upon on-going SFSA research and continued efforts by SFSA members to develop process improvements, a SFSA team of members and researchers began to discuss opportunities for utilizing a naturally pressurized gating system for investment castings. As of early 2019, those involved were only aware of one instance where a foundry utilized bottom gating of an investment casting, but not truly a naturally pressurized gating design for investment castings. The team discussed factors that need to be considered in developinG a naturally pressurized gating system. Unlike in traditional investment castinG riGGinG where it has a center tree / sprue that also acts as the riser, we needed to consider having a separate sprue and a feeder.
