Frequently Asked Questions

Can you support our PPAP requirements?

Yes, for production orders, we can work with you to provide the required elements of a PPAP submission, including dimensional layouts, material certifications, and process control plans.

What is your lead time for automotive prototypes?

We specialize in rapid prototyping. Depending on complexity, we can often deliver CNC machined prototypes in as little as 3-7 business days, helping you accelerate your R&D cycles.

Do you work with electric vehicle (EV) startups?

Absolutely. We are an ideal partner for EV companies, offering the speed and agility needed for prototyping and the scalability required to move into production for components like battery enclosures, motor housings, and busbars.

What is the most common aluminum for automotive parts?

6061-T6 is the most versatile and widely used for a variety of brackets, chassis, and general components. For high-stress applications like suspension parts, 7075-T6 is often preferred. For high-volume die-cast parts, A380 is the industry standard.

Can you handle high-volume production runs?

Yes. Our facility is equipped with automated systems like bar feeders for CNC turning and robotic cells for die casting, making us highly efficient for production runs of thousands to hundreds of thousands of parts.

How do you ensure quality and consistency in a large production run?

We use Statistical Process Control (SPC) to monitor critical dimensions throughout the production process. Regular in-process inspections ensure that any deviation is caught and corrected immediately, guaranteeing consistency from the first part to the last.

What is the best finish for a chassis or suspension part?

For maximum durability and corrosion resistance, a multi-layer finish is often best. This typically involves a protective coating like E-coating or Zinc Plating, followed by a durable topcoat like Powder Coating.

Do you offer any services for motorsport/racing teams?

Yes, our rapid prototyping and expertise with high-performance materials like titanium, 7075 aluminum, and PEEK make us an excellent partner for motorsport teams that require lightweight, high-strength, custom components on a tight deadline.

Can you machine castings from another supplier?

Yes, we frequently provide secondary CNC machining services on castings or forgings provided by our clients to add high-precision features.

How do you ensure your material is genuine and meets specifications?

We source all materials from certified, reputable suppliers and can provide Mill Test Reports (MTRs) to verify the chemical composition and mechanical properties of every material lot we use.
