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: For parts like crankshafts, cylinder heads, and transmission housings, CNC machining delivers the extreme precision necessary for optimal performance, efficiency, and reliability, meeting the exacting tolerances these components require.
- 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: Caliper mounts, rotors, and pedal components are machined for safety and smooth function. Surface finish, tolerance, and geometry are critical to ensure effective braking performance.
- Interior & Dashboard Hardware: CNC machining isn’t limited to engine parts—it’s also essential for crafting aesthetic and functional components like gear shifters, infotainment brackets, and dashboard support structures.
- Prototyping & R&D: Automakers often turn to CNC-machined prototypes to validate the performance, safety, and fit of components before full production begins. Roberson helps facilitate a smooth transition from CAD models to physical parts, accelerating design validation and innovation.
- Electric Vehicle (EV) Components: The growth of electric vehicle production relies on CNC machining for components like battery housings, cooling plates, and custom mounts for electric drive units, demanding new design techniques and material choices.
- Autonomous Vehicle Systems: Precision-machined parts are fundamental for the operation of sensors, control modules, and structural components in autonomous vehicles, ensuring high performance and reliability in complex driving systems.
- Performance & Aftermarket Parts: CNC machining makes it possible to produce custom parts like intake manifolds, exhaust headers, and suspension upgrades, allowing automotive enthusiasts to improve their vehicle’s performance and visual appeal.
Roberson’s automotive part manufacturing services are designed to meet the industry’s high expectations—whether you’re producing 5 parts or 5,000. Precision, consistency, and quality are always the standard.
Types of Materials We Use for Detroit, MI, Automotive CNC Manufacturing
In automotive manufacturing, material selection is key to ensuring the performance, safety, and longevity of vehicle components. At Roberson Machine Company, we leverage a diverse selection of metals and plastics, each chosen for its unique strengths—strength, weight, corrosion resistance, and machinability—to fulfill the precise needs of automotive applications. This includes:
- Aluminum (6061, 7075, 7050): Lightweight and highly resistant to corrosion, aluminum alloys are widely used in manufacturing engine components, suspension parts, and housings. 7075 alloys are particularly favored in high-performance and motorsport applications.
- Stainless Steel (303, 304, 316, 321, 420SS, 416, 440): Stainless steels are prized for their strength and corrosion resistance, making them ideal for applications like exhaust systems, fasteners, and drivetrain components. For detailed insights on stainless steel, check out What Is Stainless Steel?. Hardened grades like 440 are especially known for excellent wear resistance.
- Plastics (Delrin, PETGs, Nylon, PLAs, PEEK, HDPE, Glass-Filled Nylon): These materials are ideal for lightweight, non-structural parts such as bushings, gears, and interior components. Certain types, like PEEK, are resistant to high heat and chemicals.
- Brass: Ideal for fittings, bushings, and valves due to its machinability and corrosion resistance. Commonly found in fluid-handling systems and connectors.
- Titanium: With its remarkable strength and lightweight nature, titanium is a top choice for applications where performance and weight are critical, such as exhaust components and racing parts.
