Renewable Energy Manufacturing FAQ
Common questions from energy engineers about our precision manufacturing capabilities for wind, solar, and storage systems.
What materials do you recommend for outdoor renewable energy components?
For structural parts exposed to weather, we typically recommend 316L stainless steel for superior chloride resistance (critical near coastal or offshore sites), hot-dip galvanized carbon steel per ASTM A153 for cost-effective corrosion protection, or aluminum 5052-H32 for lightweight brackets with good saltwater resistance. For high-temperature applications such as inverter heat sinks, aluminum 6061-T6 offers an excellent strength-to-weight ratio with thermal conductivity of ~167 W/m·K. Material selection depends on your specific environmental exposure, mechanical loads, and design life target.
What tolerances can you hold for wind turbine drivetrain components?
For bearing seats and shaft interfaces we can achieve ±0.0005" (±0.013 mm) with surface finishes of Ra 0.8 µm or better — critical for proper bearing preload and fatigue life in pitch and yaw systems. Structural brackets and adapter plates are typically held to ±0.005" (±0.13 mm). Our 5-axis CNC capability allows tight tolerances on complex multi-feature parts like yaw gear rings where concentricity and perpendicularity are critical.
Can you manufacture components for IP65 or IP67 battery enclosures?
Yes. We fabricate enclosure components for battery module and rack builds—housings from stainless 304/316 or aluminum 5052/6061 sheet metal with O-ring gland machining, gasket channels, and sealed cable entry points used in IP65 or IP67 designs. We can also include threaded inserts for EMI gaskets and provide powder-coated or anodized finishes. Typical wall thickness ranges from 1.5 mm to 3 mm depending on structural and thermal requirements.
What surface treatments extend outdoor component life to 20+ years?
For aluminum parts, Type III hard anodize (per MIL-PRF-8625) provides an abrasion-resistant oxide layer of 0.002-0.003". TGIC polyester powder coat (2-5 mil) adds UV resistance designed for up to 10+ year exterior exposure in typical conditions. For steel, hot-dip galvanizing per ASTM A153 provides 50-100 µm zinc coating that sacrificially protects the base metal. Stainless steel parts benefit from citric acid passivation per ASTM A967 to maximize the chromium oxide passive layer. We recommend combining treatments — for example, anodize + powder coat — for extreme environments.
Do you support prototype-to-production scaling for energy hardware?
Absolutely. We handle the full development cycle: 3D-printed concept models typically in 1-3 days, CNC-machined functional prototypes typically in 10-15 days, and production batches of 100-10,000 pieces with rigorous quality control. All production parts include material certifications (mill certs per ASTM/ISO standards), dimensional inspection reports, and full traceability. This lets you validate form, fit, and function before committing to production tooling.
Can you machine hydrogen fuel cell bipolar plates?
Yes. We machine PEM fuel cell bipolar plates from 316L stainless steel or graphite composite blanks. Our 5-axis capability allows us to cut flow-field channels with typical widths of 0.5-1.5 mm and depths of 0.3-1.0 mm with ±0.05 mm precision. We also machine end plates with precision O-ring grooves for stack sealing. Surface finish on sealing faces can achieve Ra 0.4 µm or better for gas-tight assembly.
