Eagle Alloy, Eagle Precision and Eagle CNC plan to maintain full production capability, even in light of the recent decision by Michigan’s Governor to close all “nonessential” businesses.
This introduction to metalcasting provides a brief overview and history of the casting process, as well as an outline of common casting techniques in use today. The goal of this article is to give new manufacturers a better understanding of how metalcasting works and what steps are involved in producing cast products. By the end of the article, the reader should have a clear picture of the opportunities presented by metalcasting, and a sound appreciation for its potential as a modern manufacturing method.
Metalcasting is a modern manufacturing industry, and cast products are utilized in 90% of durable goods, from lamp posts to space shuttles. Still, no casting is perfect. Even with recent innovations in simulation and process technology, nearly every cast product will contain some level of defect. A clear understanding of casting defects is vital for any casting customer, as it helps guide realistic expectations when working with a casting facility.
While experienced casting facilities are skilled in finding a balance between cost and quality, purchasers should be closely involved in determining admissible levels of defects in deliverable products.
In our blog series, Casting Advocates, we explore the work of organizations and industry leaders who work to elevate the metalcasting profession. Here in this first installment, we focus on the Steel Founders' Society of America.
The Steel Founders' Society of America (SFSA) was first organized in 1902, and initial meetings were a "luncheon club" attended by a handful of casting companies from the Midwest and the East Coast. After more than a century of evolution, SFSA is now a major force in promoting metalcasting competitiveness industry-wide. Today, SFSA works to provide members with the tools and knowledge to succeed in today's high-tech manufacturing environment.
Forget about the Rose Bowl–this year's college competition to watch is coming up in February!
The AFS Wisconsin Regional Invitational Casting Competition will host casting teams from colleges and universities around the Midwest. Taking place during the AFS Wisconsin Regional Expo and Conference, the event invites student teams to present cast products they've created using school casting facilities. All projects in competition were completed by members of AFS student chapters.
Cem-Tec, a manufacturer of steel light poles in business since 1974, approached Eagle Alloy, Inc. with an emergency order. Due to an unforeseen supply-chain issue, they needed to find a new foundry to manufacture one of their popular products. With orders in and customers waiting, the clock was already ticking.
The following case study illustrates the steps Eagle Alloy followed to transfer casting of the product to our facility and to ensure that Cem-Tec had high-quality products ready for their customers as soon as possible.
Eagle Alloy was lively and bustling on Thursday, October 4th. That's no surprise: our Muskegon, MI campus is regularly buzzing through three shifts a day, five days a week. But this particular day brought in a larger crowd than usual: in celebration of Manufacturing Day 2018 we opened our campus to local schools and community representatives for a demonstration of modern metalcasting.
The goal of Manufacturing Day is to inspire the next generation of manufacturers, and we wanted to support that goal any way we could. By inviting students to witness our work firsthand, we aimed to provide an introduction to modern metalcasting and manufacturing. After nearly 40 years in business, we understand the importance of letting young people know about the exciting potential of metalcasting careers.
Product development processes vary widely from foundry to foundry. The Eagle Group's Product Development blog series aims to highlight practices used by leading foundries that prioritize quality in every part they produce.
One product development practice that sets Eagle Alloy apart from other shell molding foundries is their use of a handheld laser scanner for inspection and dimensional reporting. This technology greatly improves the accuracy of dimensional reports, and makes it easier for customers to verify that new parts meet their requirements.
APQP, or "Advanced Product Quality Planning," is a product-design process developed by automakers in the 1980s. Since then, a large number of businesses have adopted APQP for the product development stage.
A major portion of APQP is devoted to planning the production process, and making the right design decisions at an early enough stage to prevent expensive corrections later. When APQP is carried out correctly, it's a comprehensive and complete process. The foundry will engage the customer on multiple levels to learn everything they can know about the product, its end use and its working environment before finalizing design.
Every manufacturer bringing a cast product to market must decide on the right casting process to use. Casting methods like shell molding, greensand casting, investment casting and airset casting all have their own sets of benefits and drawbacks. The right choice depends on the quantity being cast, the size of the part, and the requirements for dimensional accuracy, surface finish and material.
While it's not as widely used as shell molding or greensand casting, airset casting has plenty of advantages, and can be the perfect option for the right product.
