Frequently Asked Questions

Common questions about our automotive manufacturing services and capabilities

What automotive quality certifications do you have?

We are IATF 16949:2016 certified, which is the international automotive quality management system standard. We also maintain ISO 9001:2015 certification and comply with customer-specific requirements from major automotive OEMs including Ford Q1, GM Global A, and Chrysler QSB.

What tolerances can you achieve for automotive parts?

Our precision CNC machining capabilities can achieve tolerances as tight as ±0.001" (±0.025mm) for critical automotive components. For injection molded parts, we typically maintain ±0.002" to ±0.005" depending on part geometry and material selection. All dimensions are verified using coordinate measuring machines (CMM).

Do you support just-in-time (JIT) delivery for automotive production?

Yes, we have extensive experience with JIT delivery systems required by automotive manufacturers. Our production planning and logistics capabilities are synchronized with customer assembly schedules, ensuring parts arrive precisely when needed to minimize inventory costs and prevent line stoppages.

What materials do you work with for automotive applications?

We work with a wide range of automotive-grade materials including aluminum alloys (6061, 7075, A380, A383), steel grades (carbon steel, stainless steel, tool steel), engineering plastics (ABS, PC, PA66, POM), and specialized alloys for high-performance applications. All materials come with full material certificates and traceability.

What is your typical lead time for automotive parts?

Lead times vary by complexity and quantity. For prototypes, we typically deliver in 3-7 days. For production tooling, lead times range from 2-6 weeks depending on complexity. Once tooling is completed, production parts can be delivered in 1-3 weeks for initial orders, with ongoing production scheduled based on customer forecasts.

Do you provide design for manufacturing (DFM) support?

Absolutely. Our experienced automotive engineers provide comprehensive DFM analysis to optimize part designs for manufacturability, cost reduction, and quality improvement. We review designs for material selection, processing methods, tooling requirements, and assembly considerations to ensure optimal production outcomes.
