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, target grade or service environment, and annual volume. Same-day technical feasibility review. Full quote within 48 hours, including tooling, freight, and customs where applicable.
Review the quote and production plan. Sign the production agreement. Redstone confirms grade, facility assignment, tooling timeline, and first-article schedule.
Wax-pattern tooling takes 3 to 5 weeks. First-article samples ship to your engineering team for sign-off. PPAP package available on regulated programs.
Volume stainless casting runs at the assigned IATF 16949 certified facility. Statistical process control applied from first article. Lot traceability and heat-number records maintained end to end.
Third-party inspection at origin against your approved drawings and tolerances. Dimensional report, visual inspection, and material certification with heat number included in every shipment. US customs brokerage handled. Landed cost on your dock matches the number Redstone quoted.

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.

CF8 is the cast form of 304 stainless and CF8M is the cast form of 316. CF8M adds molybdenum, which resists chlorides, salt, and acidic media that pit 304. Use CF8 for general corrosion service and CF8M for marine, chemical, and food or sanitary parts. Send your service environment and Redstone confirms the grade at the feasibility review.
Yes. Investment casting produces dense, fine-grained stainless that runs pressure-tight for valve and fluid-handling bodies. Castings are verified under hydrostatic or pressure-decay test to your drawing before shipment on programs that call for it.
500 units per cycle for stainless investment casting. $50,000 minimum program value. Volume programs only. Multi-year preferred.
A 125 to 250 microinch Ra as-cast surface is typical. Bead blasting, pickling, passivation, and electropolishing are available, with machined sealing faces to drawing. For food and sanitary parts, Redstone confirms the passivation or electropolish spec against your washdown environment at the quoting stage.
Yes. Send the existing tool drawings, PPAP package, and current supplier quote. Redstone assesses tool transfer feasibility, runs a parallel quote with the certified facilities, and projects landed-cost savings and lead-time impact before you commit. Existing tooling is often re-usable in Redstone equipment.
