❓ Precision Casting FAQ

🔹 What are the advantages of carbon steel in investment casting?

Carbon steel provides excellent strength-to-weight ratios and is highly cost-effective for mass production. It allows for a wide range of heat treatment options to achieve specific hardness and toughness requirements.

🔹 What is the typical lead time for custom OEM parts?

Usually, mold design and prototyping take 2-4 weeks, with mass production following in 4-6 weeks depending on complexity and surface treatment requirements.

🔹 How does JUNLONG ensure metallurgical integrity?

Every melt is tested using optical emission spectrometers. We provide Material Test Reports (MTRs) and 3.1 certificates upon request for full traceability.

🔹 Can you handle complex internal geometries?

Yes, investment casting (lost wax) is ideal for complex shapes that are impossible or too expensive to machine. We use ceramic cores for intricate internal passages.
