Willman Industries Inc. is a full-service jobbing foundry offering design, pattern making, heat-treating and machining; specializing in no bake and green sand molding producing both grey and iron ductile castings.

Big and bold on the home page of its web site www.willmanind.com the company proclaims—"Quality Castings That Meet Your Requirements."

According to Randy Parker, Willman's Quality Manager, part of that quality assurance can be attributed to an Artec Eva 3D Scanner purchased from Exact Metrology back in late July last summer. A handheld and targetless [requiring no reference markers or calibration] scanner, the Eva can be compared to a video camera which captures in 3D. Below you can see just how easy the Eva is to operate as a Willman Industries employee uses it to scan a casting.

Parker was already familiar with the benefits of 3D Scanners as he was looking to upgrade from an older Laser Scanner and Faro Arm. Having worked with Exact Metrology at his previous employer, he knew he'd get the "Exact" piece of equipment he needed with the help of the Exact Metrology team.

"Technical expertise" was the advantage that sold him on working with Exact Metrology again. "Efficiency working with large castings up to 30,000 pounds" was the benefit that sold him on the Eva.

Since its purchase, Parker says the Eva has been in use practically every single day in some capacity or another and estimates it has been instrumental in QA on approximately 50 jobs so far.

Parker says the Eva has "worked out well beyond expectations."

"We've made numerous improvements to our process with it. Our dimensional control has improved not just from measuring the castings but from checking multiple process inputs with the Eva."

"We've greatly expanded the primary use we bought it for as well, to include problem solving, tooling analysis, pattern & mold scanning, and reverse engineering."

Parker knew the Eva would help supply layout castings more rapidly but is amazed at the actual pace. Some tasks are accomplished in 75 percent less time and he cited some castings that historically would have stretched over a period of seven to 10 days now being done in six to 10 hours.

He refers to the Eva as "crazy efficient." Adding, "The rate at which you can capture data is fantastic."

PolyWorks is the software of choice to process the data.

"Without a doubt the Eva has saved our company money," confirms Parker. 'We definitely promote it to customers as a valuable tool that will enable us to meet their castings' requirements."

Here are some of the various other objects Exact Metrology was requested to scan just this past January alone:

1) Motorcycle Engine (to complete some patent documentation)
2) High Heel Shoe Mold (for designing product-ready shoes)
3) Small Bevel Gear (being reverse engineered)
4) Dodge 440 Block (for entering into Cad Program) to prototype parts off of
5) Small Aluminum Tube (which is an explosive device)
6) Parking Lots
7) WWII Era M1 Garand Military Rifle
8) Stone Carvings on the Face of a Building
9) Wheel Well of a Race Car
10) Initial Small Sculpture for prototype of
3' x 4' Castings of Cartoonish Birds

What can we QUOTE for you?

Industrial CT Scanning will be performed by Exact Metrology within 60 days. Our state-of-the-art v|tome|x M300 Metrology Edition System from GE is currently being set up in our Cincinnati office. Many companies are turning to CT Scanning for non-destructive 3D Testing, reproducible 3D metrology and scientific research applications.

This Month’s Featured Product:

Artec EVA Color 3D Structured Light Scanner Studio Software

Artec™ Eva 3D Scanner is similar to a video camera which captures in 3D. The scanner captures up to 16 frames per second. These frames are aligned automatically in real-time, which make scanning easy and fast. This is especially important for the creation of special effects, medical and biomechanical research. Because of the high quality, Eva’s textured models can be used in such industries as CG/Animation, forensics and medicine.
