Precision CNC machining, run in-house on our own automated 5-axis equipment in Seattle. The same standards and oversight we bring to our global production network, run on our own machines under our own roof. Redstone is not a broker: when we say we are a manufacturer, we mean we run the machines.

See Our Process Or same-day technical feasibility review
Share your part details, drawings, or CAD files. Redstone will review the requirements and confirm feasibility, tolerances, materials, lead time, and next steps.
Final specifications are confirmed during the technical feasibility review.
Redstone helps hardware teams move from released drawings to repeat production with documented quality, competitive unit costs, and engineering support from the U.S.
Standardized workholding and in-process inspection keep parts in family run after run, with first-article validation on new programs and ongoing checks throughout production. The Seattle facility is where we prove what disciplined, automated manufacturing looks like.
We do not outsource the hard part. Our team writes the CAM, designs the workholding, and builds the robotic automation ourselves, so process improvements compound over thousands of parts instead of getting lost between vendors. One accountable partner from quote to delivery.
Our floor runs Brother Speedio mill-turn cells, each tended by an integrated robot and designed for unattended, overnight production. Combining turning and milling in a single setup means fewer handoffs, tighter tolerances, and consistent parts at volume.
Redstone supports production metal parts across automotive, electronics, industrial equipment, and consumer hardware programs.
Prismatic housings, brackets, and contoured parts machined complete on automated 5-axis mill-turn cells in aluminum and stainless.
Shafts, bushings, and threaded components turned and milled in a single setup, with the workholding designed and proven in-house.
Compound-angle and contoured features that need a single-setup 5-axis approach, programmed and proven on our own equipment.
Low-to-mid volume programs that benefit from robot-tended, lights-out cells, with room to scale capacity on the existing floor.
From initial drawings to final delivery, Redstone keeps each stage clear, documented, and aligned with production requirements.
Each handoff is documented. No stage moves forward until drawings, materials, and production requirements are confirmed with the customer.
Send part files, material spec, and annual volume. Same-day technical feasibility review, with a full quote that includes programming, workholding, and freight.
Review the quote and production plan, then confirm the program. Redstone assigns the work to a cell at the Seattle facility and sets the first-article schedule.
Our team writes and proves the CAM and designs the workholding in-house. First-article samples go to your engineering team for sign-off before the run.
Volume machining runs on robot-tended mill-turn cells, including unattended overnight production. Standardized workholding and in-process checks hold parts in family.
First-article and in-process inspection against your model and tolerances, with a dimensional report on the program. Parts ship domestic from Seattle, with no customs step in the schedule.

Casting vs machining compared across cost, tolerances, volume, and lead time. Learn which manufacturing process fits your metal part production needs.
Metal injection molding design requires uniform wall thickness, proper gating, and sintering shrinkage planning. Learn the key MIM part design rules before you commit to tooling.
CNC machining tolerances range from ±0.005" standard to ±0.001" tight. Learn the standards, callout types, and charts that keep rework and cost under control.
2024 and 6061 are both workhorse aerospace alloys, but they serve opposite needs: 2024 delivers high strength and fatigue resistance under tension, while 6061 offers superior corrosion resistance, weldability, and fabrication versatility.
7075 aluminum nearly doubles the tensile strength of 6061 and dominates aerospace tooling, but it is generally considered non-weldable and harder to form. 6061 offers superior corrosion resistance, weldability, and fabrication versatility for a broader range of industries.
6061 aluminum can be bent, but its precipitation-hardened T6 temper makes it prone to cracking if handled without the right techniques. Proper bend radii, annealing, and controlled heating are all essential for successful results.
A36 and AR500 are two common steel grades with very different strengths. A36 is valued for workability and low cost; AR500 is engineered for extreme wear and abrasion resistance.

Don’t see your question? Request a quote and our engineering team will answer it.
No. We own and operate a CNC machining facility in Seattle and run the machines ourselves. That is the difference: when we say we are a manufacturer, we mean it. The Seattle shop anchors a broader model that pairs U.S. capability with a vetted global production network, so each part is made where it makes the most sense without sacrificing oversight.
Our floor runs Brother Speedio mill-turn cells, each tended by an integrated robot, designed to keep machining unattended through the night. Combining turning and milling in one setup means fewer handoffs, tighter tolerances, and consistent parts at volume.
We do not outsource the hard part. Our team writes the CAM, designs the workholding, and builds the robotic automation ourselves. Because that work stays in-house, process improvements compound over thousands of parts instead of getting lost between vendors.
Aluminum 6061 and 7075, and stainless 17-4 on the Seattle floor. Additional metals and plastics, including titanium and engineering-grade polymers, are available through our global production network, and secondary processing such as anodizing, powder coating, and plating is coordinated the same way, so you still have one accountable partner from quote to delivery.
When keeping a program in the country, time-zone control, or domestic lead time matters more than the lowest unit price, the Seattle facility is the fit. There is no customs step in the schedule. For higher-volume or specialized work, that same discipline extends across our global production base.
Yes. Send the existing drawings, current inspection data, and supplier quote. Redstone assesses the program, runs a parallel quote, and projects lead-time and cost impact before you commit. Existing fixtures and programs are often re-usable.
Yes. Prototype components are machined on the same equipment that will handle your full order, so the prototype accurately represents the final component in fit, finish, and mechanical properties, and the program is already proven when you move to production.
Tolerance capability depends on the material, geometry, and feature size. Combining turning and milling in a single 5-axis setup removes re-fixturing between operations, which is where tolerance stack-up usually creeps in. Send your drawing and we confirm what is achievable for your part at the technical feasibility review.
The Seattle floor is built for repeatable low to mid volume programs on robot-tended mill-turn cells, from prototypes and small batches through recurring production runs, with room to scale capacity on the existing floor. For high-volume programs, the same oversight extends across our global production network.
3D printing works well for visual mockups and early geometry validation. CNC machining produces functional metal and plastic components with superior surface finish, tighter tolerances, and stronger mechanical properties. For industrial-grade production parts, machining remains the standard.
