What Off Site does

Off Site Manufacturing (legal entity Off Site Technologies) is a privately held precision CNC machining contract manufacturer operating from a single facility at 50350 E. Russell Schmidt Blvd, Chesterfield Township, Michigan, where it has continuously performed precision manufacturing since 1938. The company was formally founded in 1992, building on a manufacturing-engineering team assembled in 1985, and today machines iron, steel, aluminum, and brass components to ±0.0005 inch tolerances under an IATF 16949:2016-certified quality management system. Its core offerings include CNC turning and milling, drilling and tapping, broaching, dynamic balancing to ISO G2.5 at operating RPM, coating (E-coat, powder coat, paint, plating), sub-assembly and kitting, and full PPAP/quality inspection. A plant-wide real-time Statistical Process Control (SPC) platform monitors every critical dimension, supported by CMM inspection up to 60 x 30 x 24 inches at ±0.0002 inch accuracy, laser part identification (2D DataMatrix and QR codes) for heat-lot and tool-offset traceability, and eddy-current-driven thermal compensation (spindle chillers reducing thermal error by approximately 65%) in climate-controlled work zones held at 20 °C ±1 °C.

The company serves OEM and Tier 1 supply chains in heavy-duty commercial truck (Class-8), diesel engine, defense/military vehicle, automotive cooling and accessory drive, water infrastructure/valves, and aerospace/general industrial markets. Named customer logos on the company website include Daimler Truck North America (DTNA), Detroit Diesel Corporation (DDC), Waupaca, BorgWarner, AMG, Clarke, EJ, GLC, MTU, and Rolls-Royce. Off Site Manufacturing also operates as an off-site production-line extension for foundries, receiving raw castings and shipping finished, assembled components directly to OEM customers under the foundry's brand (blind-ship fulfillment). The go-to-market is exclusively direct sales through RFQ intake and engineering consultation, with plant tours in Chesterfield Township and ED

Revenue model

1. Precision CNC Machining Services: Revenue generated from precision CNC turning and milling services for OEM and Tier 1 suppliers, billed per part/unit produced. Covers lathes and machining centers holding plus/minus 0.0005 inch tolerances under IATF 16949 quality management system. Volume ranges from low-volume prototype runs to high-volume production programs.
2. Finishing and Coating Services: Revenue from coating (E-coat, powder coat, paint, plating) and surface finishing services bundled with machining as a single relationship, reducing logistics headaches for customers.
3. Sub-Assembly and Kitting Services: Revenue from component sub-assembly, press-fit bearing insertion, threaded inserts, bracket builds, and kitting services delivering plug-and-play kits rather than loose parts.
4. Program Management and Contract Manufacturing: Full program management revenue covering sourcing, machining, finishing, assembly, and JIT delivery under one contract relationship with MRP integration, replacing fragmented multi-supplier arrangements.

Core offering

Off Site Manufacturing is a precision contract manufacturer that produces tight-tolerance machined components (pulleys, shafts, brackets, housings, fan bases, valves) in iron, steel, aluminum, and brass under an IATF 16949 quality system. Services are bundled as a vertically integrated program covering raw material sourcing, CNC turning/milling, drilling, broaching, dynamic balancing, finishing/coating, sub-assembly and kitting, and JIT delivery with EDI/MRP integration, replacing fragmented multi-supplier arrangements for OEM and Tier 1 customers.

Product overview

Off Site Manufacturing is a precision contract machining company offering vertically-integrated CNC manufacturing services as a unified platform. The core offering bundles sourcing, precision CNC machining (turning and milling), drilling and tapping, broaching, dynamic balancing, finishing and coating, sub-assembly and kitting, and quality inspection with JIT delivery under one IATF 16949-certified relationship. The company's named service products — CNC Turning Services, CNC Milling Services, Drilling and Tapping, Broaching, Dynamic Balancing, Coating Services, Sub-Assembly & Kitting, Contract Machining Services, OEM Manufacturing Services, and Quality Inspection & PPAP — are individually deliverable but designed to be combined under a single program-management contract, eliminating fragmented multi-supplier supply chains. The portfolio covers finished precision components (pulleys, shafts, brackets, pump housings, fan bases, and custom build-to-print parts) machined from iron, steel, aluminum, and brass, with tolerances held to ±0.0005 in.
