US-Based Precision Manufacturing That Meets Your Print
Sindri Engineering provides precision aerospace manufacturing from our facility in Santa Ana, CA. We specialize in machining complex castings and forgings, super alloys like Inconel, and flight-critical hardware that has to be right the first time.
With clear communication, realistic lead times, and parts that arrive on spec, we act as an extension of your engineering and supply chain teams—not just another job shop.

Manufacturing Engineering Support Process
3D Printing for Prototyping and
Low-Volume Production
Get fast, accurate 3D printed parts without committing to full-scale machining. We offer 3D printing as a dedicated service for aerospace and industrial customers.
Prototyping
Validate form, fit, and function quickly to iterate designs before locking in production.
Low-Volume Production
Small batches for testing, spares, and niche programs where traditional tooling isn’t feasible.
Materials
Fiber-reinforced materials, nylons, and other high-performance engineering materials.
Processes
FDM and resin SLA printing matched to your part’s strength and surface finish targets.
Whether you’re proving out a new design or supporting a low-volume program, our 3D printing services help you move faster with less upfront cost.
Documented Processes
Documented, repeatable processes for every job ensuring consistency and precision across all manufacturing phases.
Quality-Driven Manufacturing with ISO 9001 Processes
Quality is built into every step of our manufacturing process. Our workflows are aligned with ISO 9001 requirements and customer expectations, from quote through final inspection.
Inspection Planning
First Article Inspection (FAI) and comprehensive production inspection plans using calibrated measurement tools.
Full Traceability
Full traceability of materials, revisions, and inspection records to support your audits and production schedules.
