What CG Hill & Sons does

CG Hill & Sons is a third-generation, family-owned custom OEM capital equipment manufacturer founded in 1947 and headquartered in Mounds View, Minnesota. The company designs, fabricates, and assembles custom automated machinery, mechanical and electrical subassemblies, precision CNC-machined parts, UL 508A certified control panels, and welding/fabrication services for customers ranging from niche manufacturers to Fortune 100 enterprises across roofing/shingle, filtration, windows, automotive, packaging, paper, medical, and personal protection equipment verticals. Its most differentiated product line is the Granule Adhesion Test Machine (GATM), developed in an exclusive joint venture with 3M to test shingle sealant adhesion per ASTM D 4977, offered in single-head ($12,464) and four-head ($31,230) configurations.

The company operates from two adjacent facilities totaling 96,000–120,000+ sq ft, equipped with HAAS 5-axis CNC machining centers, 13 CNC vertical mills, 2 CNC horizontal mills, 5 CNC lathes, dual bridge-crane assembly bays with 24-foot clearance, 1600 Amp 480V power, climate-controlled CMM inspection, and dedicated panel-build workspace. The business model is primarily project-based: custom CapEx machine building and assembly work is quoted per project with NET 30 terms on orders over $5,000, while standardized GATM equipment and parts under $5,000 are sold direct through a Shopify e-commerce store with credit-card processing. Customers engage through a quote-request workflow that covers concept, design, fabrication, assembly, electrical integration, on-site test run, and after-sale repair services, with no handoffs between stages. Marketing is conducted through a corporate website, LinkedIn, Facebook, Instagram, TikTok, and YouTube, with the go-to-motion centered on direct enterprise field sales and longstanding customer relationships.
