Aerospace Manufacturing Excellence in California
The manufacturing industry in California has deep roots in the aerospace industry. As such, being able to produce complex designs with precision and speed is essential in order to be a trusted partner. PEN Manufacturing has long been an ally for aerospace companies pushing the boundaries of technology, providing high-quality prototypes that are critical to research and development. Our expertise in one-off, custom prototypes enables aerospace innovators to test, refine, and validate new designs before committing to full-scale production, ensuring that every part is mission-ready.

Precision and Flexibility for Complex Prototypes
Aerospace R&D demands a level of precision that allows for complex geometries, tight tolerances, and high-quality finishes. At PEN, we’re equipped with advanced CNC and 4-axis machining capabilities that empower us to meet these exacting requirements.
Whether it’s components for new propulsion systems, lightweight structures, or advanced control mechanisms, our ability to create custom parts supports every stage of design validation.

Speed Without Compromising Quality
In the aerospace industry, time is often as critical as quality. PEN Manufacturing understands the importance of delivering prototypes on tight schedules, which is why we have streamlined our processes for rapid turnaround without sacrificing precision.
Support from Concept to Testing
Our team works closely with engineers to provide end-to-end support through each phase of R&D. By producing prototypes that are true to design, we allow engineers to test components in real-world conditions, making it possible to refine and optimize their ideas before they move to production. This collaboration minimizes costly redesigns and accelerates time-to-market for breakthrough aerospace technologies.
