Southern California Investment Casting |
Aerospace & Defense
Southern California’s aerospace and defense manufacturers depend on high-precision components that can survive extreme heat, pressure, and mechanical stress — and investment casting is the process that makes those parts possible. Investment casting has become an integral manufacturing method in aerospace engineering, delivering precision, complexity, material strength, and consistency that few other processes can match.
For industries designing next-generation engines, lightweight structures, and high-temperature components, aerospace investment castings offer the accuracy and resilience needed to ensure safety, performance, and innovation at every altitude.
Critical Supply Chain Challenges Facing California Aerospace Manufacturers
Our hybrid ceramic 3D printing and investment casting process eliminates these bottlenecks by removing seven of those twelve traditional steps — delivering first castings in days, not months, with zero tooling investment required.
Services Offered in California
Precision Investment Casting for Aerospace Applications
Our precision investment casting capabilities are built for California’s aerospace and defense industries. Using LAMP™ technology, we 3D print ceramic shell molds directly from CAD files, bypassing wax patterns and lost wax casting tooling. Molten metal is poured to produce high-precision components from aerospace-grade alloys, including titanium, Inconel, Hastelloy, stainless steels, and specialty superalloys. Each casting meets ASTM standards and tight dimensional tolerances for critical applications, from turbine components to structural airframe parts.
Rapid Prototyping and Low-Volume Production
Our tooling-free rapid prototyping combines ceramic 3D printing with investment casting, reducing lead times from 12–17 weeks to days. Engineers can quickly move from CAD to poured, finished prototypes, validating material properties and iterating designs for production. This supports California aerospace R&D programs needing high-precision components, fast innovation, and competitive pricing.
CNC Machining Services and Post-Casting Operations
We provide turnkey CNC machining services, turning cast blanks into fully finished, inspection-certified components. Post-casting operations include 5-axis CNC milling, precision drilling, threading, and surface finishing to aerospace Ra specifications. Every component undergoes CMM inspection, ensuring quality investment castings and reliable time delivery for California aerospace and defense programs.
Our Advanced Manufacturing Process in California
Our hybrid ceramic 3D printing and investment casting process eliminates the tooling bottlenecks that have historically plagued California aerospace project timelines. Our streamlined process includes:
- Direct ceramic shell 3D printing from CAD files — no wax patterns, no injection molds required
- Traditional investment casting metallurgy that preserves material properties and ASTM compliance
- Rapid iteration capability supporting California's fast-paced aerospace development cycles
- Integrated post-casting machining and finishing for turnkey component delivery
- Quality control and inspection processes aligned with AS9100 aerospace standards
The result is a casting program that delivers production-quality metal parts in 10 days, where traditional suppliers need multiple weeks or months.

Frequently Asked Questions About California Investment Casting
We cast a wide range of aerospace-grade alloys, including titanium, Inconel, Hastelloy, stainless steels, aluminum alloys, and specialized superalloys — including single-crystal and directionally solidified materials for turbine applications. Investment casting preserves superior material grain structure compared to machined or fabricated alternatives, making it the preferred process for high-stress, high-temperature critical components across California's aerospace and defense programs.
Yes. The lost wax investment casting process, and our ceramic 3D printing equivalent, excels at producing complex internal cooling passages, thin-wall structures, undercuts, and intricate geometries that are impossible to achieve through machining alone. Turbine blade cooling channels, hollow structural airframe fittings, and complex manifold geometries are all well-suited to our process, with no additional tooling cost for geometric complexity.
