Case Study: MAC Equipment achieves 88% Spheri Valve weight reduction and improved design with 3D Systems' On Demand QuickPlastic urethane casting

MAC Equipment Relies on 3D Systems' Expertise to Determine Best Solution

MAC Equipment, a 40‑year leader in pneumatic conveying and air filtration, needed a lightweight prototype of its 75 lb cast‑iron Spheri Valve® but faced difficulties meeting critical small features, post‑assembly requirements and brand color matching through its existing suppliers. Unsure which process would work, MAC sought a partner who could deliver precise, production‑like models while advising on the best manufacturing approach.

3D Systems’ On Demand Manufacturing recommended QuickPlastic™ cast urethane and handled post‑processing and color matching, producing highly detailed valve models that preserved all small features. The result: parts shrunk from 75 lb to 9 lb, improved product design and productivity, and a smooth project experience credited to clear communication and close attention to detail.
