Top Die Castings

What Top Die Castings does

Top Die Casting Company (dba Top Die Castings) is a privately held, family-owned custom manufacturer founded in 1977 and headquartered in South Beloit, Illinois. The company operates three plants across Northern Illinois and produces aluminum high-pressure die castings, custom thermoplastic injection molded parts, machined components, and finished/assembled goods for industrial manufacturers, with Caterpillar explicitly named as an enterprise customer. Its technical core comprises 22 high-pressure die cast machines (650T–1250T) supporting aluminum alloys 360/380/383/384/413, a 25,000 sq ft CNC machining facility with 55 machines, an in-house tool shop with CAD import and mold-flow analysis, and a 300-ton injection molding line with 24/7 capability (operated through wholly-owned Top Die Plastics, Inc., established 2002).

The business is run as a single integrated one-stop-shop combining die casting, plastic injection molding, CNC machining, tool design and fabrication, secondary operations (vibratory deburr, shot blast, washing, trimming), and finishing (polishing, packaging) under one ownership. Quality is asserted through ISO 9001:2015 certification, Six Sigma methodology (Black/Green Belts, SPC, root-cause analysis), PPAP capability, real-time fluoroscopic x-ray inspection, CMM inspection, and a Caterpillar Supplier Quality Excellence Award. Production runs scale from single prototypes up to 30,000+ units per month.

The company sells exclusively through direct sales (Brett Scarpetta is the named contact), with pricing disclosed only via custom quote based on design, material, and volume. Pricing is not publicly listed. There are no disclosed funding rounds, no institutional investors, and no public listing; ownership commentary describes a 'financially sound and family owned business' continuously operating since 1977 with all revenue funded internally. Marketing is limited to a corporate website, a YouTube channel, and direct phone/email contact — there is no distributor, marketplace, or third-party channel presence.
