If you run a manufacturing, food & beverage, agriculture, material handling, construction, heavy equipment, pharmaceutical, or water-treatment operation in the Midwest, you already know how frustrating it is to deal with long lead times, material shortages, and machine shops that don’t truly understand plastics.
You need a plastics-only specialist that offers in-house CNC machining, custom fabrication, and one of the largest on-site inventories of sheet, rod, and tube, all under one roof with fast, reliable regional delivery.
That shop is Konrady Plastics in Portage, Indiana.
Family-owned and operated since 1981, Konrady Plastics has grown into the trusted plastic machine shop and fabrication partner for companies across Northern Illinois (including Chicago), Northwest and North Central Indiana, Southeast Wisconsin, Southwest Michigan, and beyond into Ohio. With daily regional truck delivery and nationwide shipping, we deliver precision-machined plastic components and raw materials faster than general machine shops or distant suppliers.
Why Konrady Plastics Is the Midwest’s Premier Plastics Machine Shop & Fabrication Shop
Unlike general-purpose machine shops that bounce between metals and plastics, Konrady operates a dedicated in-house plastic machine shop focused exclusively on engineered plastics. Our machinists have decades of plastics-specific experience and use state-of-the-art equipment, including Haas ST30 SSY and SL30 CNC lathes with bar feeders, CNC mills, Andi routers, and precision saws.
This specialization means we avoid common pitfalls such as warping, poor surface finishes, or out-of-tolerance parts that often occur when shops treat plastics like metal.
From rapid prototypes to high-volume production runs, every custom plastic component we produce—from wear pads, bushings, rollers, guides, and conveyor parts to complex assemblies—meets your exact specifications. We ship over one million machined plastic parts and materials annually while maintaining ISO 9001:2015 certification for consistent quality and process control.
