Green Bay, WI, Automotive Part Manufacturing: Real-World CNC Applications
Whether it’s engine parts or custom brackets, CNC machining is indispensable in the automotive industry. Roberson Machine Company works closely with Tier 1–3 Suppliers, small businesses, and other industry leaders to deliver high-precision, production-ready parts. Some typical use cases in automotive manufacturing include:
- Powertrain Components: Crankshafts, cylinder heads, and transmission housings require extreme precision to ensure performance, efficiency, and reliability. CNC machining maintains the tight tolerances these critical parts demand.
- Suspension & Steering Systems: Components like control arms, knuckles, and linkages must be lightweight, durable, and dimensionally consistent. Roberson’s machining expertise ensures each part supports proper handling and longevity.
- Brake System Parts: For caliper mounts, rotors, and pedal components, precision machining ensures safety and smooth braking. Surface finish, dimensional accuracy, and geometry are key factors in achieving reliable braking performance.
- Interior & Dashboard Hardware: Beyond the engine, CNC machining is key to producing both aesthetic and functional parts such as gear shifters, infotainment brackets, and dashboard support structures that enhance vehicle interiors.
- Prototyping & R&D: CNC-machined prototypes are a crucial step in testing component functionality, performance, and safety before full production. Roberson supports the transition from CAD designs to physical prototypes, enabling teams to innovate and validate their designs efficiently.
- Electric Vehicle (EV) Components: As EV production grows, CNC machining supports battery housings, cooling plates, and custom mounts for electric drive units—all requiring new levels of design complexity and material considerations.
- Autonomous Vehicle Systems: In autonomous vehicles, precision-machined components such as sensors, control modules, and structural parts are crucial for ensuring the performance and dependability of advanced driving systems.
- Performance & Aftermarket Parts: Through CNC machining, we produce high-performance custom parts such as intake manifolds, exhaust headers, and suspension upgrades, ideal for enthusiasts seeking enhanced vehicle performance and a personalized look.
Whether you’re producing five parts or five thousand, Roberson’s automotive manufacturing services are designed to meet the high standards of the industry. Precision, consistency, and quality are our unwavering commitments.
Types of Materials We Use for Green Bay, WI, Automotive CNC Manufacturing
Material selection is pivotal in automotive manufacturing, directly influencing the performance, safety, and longevity of vehicle components. At Roberson Machine Company, we leverage a diverse array of metals and plastics, each chosen for its unique properties—strength, weight, corrosion resistance, and machinability—to meet the specific demands of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Aluminum alloys are lightweight and resistant to corrosion, making them an excellent choice for engine components, suspension parts, and housings. High-strength alloys like 7075 are often used in performance and motorsports applications for their durability.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Valued for their strength and corrosion resistance, stainless steels are ideal for components like exhaust systems, fasteners, and drivetrain parts. Harder grades such as 440 are particularly known for their wear resistance.
- Plastics (Delrin, PETGs, Nylon, PLAs, PEEK, HDPE, Glass-Filled Nylon): These materials are great for lightweight, non-structural parts like bushings, gears, and interior components. Some, like PEEK, withstand high heat and chemical exposure.
- Brass: Offering great machinability and corrosion resistance, brass is often used in fittings, bushings, and valves in fluid-handling systems and for connectors.
- Titanium: Lightweight and exceptionally strong, titanium is used in performance applications where strength-to-weight ratio is critical, such as exhaust parts and racing components.
