Metal Stamping Services

Progressive die stamping feeds a metal strip through a series of dies in a single press stroke, cutting, bending, and forming the part in stages until the finished component exits at the end. It is the most cost-effective stamping method for high-volume parts because each stroke produces a completed part with minimal material handling.

Deep draw stamping pulls a flat metal blank into a die to form a hollow, three-dimensional shape such as a cup, enclosure, or canister. It is the right process when the finished part needs a seamless drawn form rather than a welded or assembled structure.

Fine blanking produces parts with smooth, square sheared edges and tight tolerances by applying counter-pressure during the cut. It eliminates the secondary operations typically needed to clean up a standard stamped edge, and it suits functional parts where edge quality and flatness are critical.

We stamp cold-rolled steel, hot-rolled steel, stainless steel, aluminum, copper, and brass. Material selection depends on your strength, conductivity, corrosion resistance, and formability requirements. Our engineering team confirms the best material at the feasibility review.

Standard production lead time is 4 to 8 weeks, with tooling and first-article timing confirmed at the quote stage. Rush programs can be reviewed case by case.

Progressive die tooling carries higher up-front cost, so it is built for recurring production rather than one-off parts. We will tell you at the quote stage whether your volume is a fit and recommend the most cost-effective process for your run size.

Metal stamping is a cold-forming process that presses sheet metal between a punch and a die to cut and shape it into a finished part. Operations such as blanking, piercing, punching, bending, and forming are combined in a single tool so each press stroke produces a part. Because the die does the work, stamping holds repeatable dimensions across long runs and delivers low per-part cost at production volume.

Flat or lightly formed parts at high volume suit progressive die stamping. Hollow, drawn shapes such as cups and enclosures call for deep draw. Functional parts that need smooth, square edges and tight tolerances are a fit for fine blanking. Send your drawing and target volume and our engineering team confirms the process, tooling, and material at the feasibility review.

Achievable tolerances depend on the stamping technique, die precision, and material thickness, with fine blanking holding the tightest dimensions and squarest edges. Where a part needs stricter control on a critical feature, secondary machining can refine it after forming. We confirm the tolerances your drawing calls for at the feasibility review.

Metal stamping serves automotive, electronics, industrial equipment, consumer products, appliance, and energy applications. Any program that needs repeatable, consistent parts at production volume benefits from stamped components. Our facilities are ISO 9001 certified and inspect every program against your drawing.

Stamping versus laser cutting is a volume decision. Stamping requires a tooling investment but delivers a much lower per-part cost at production quantities. Laser cutting has no tooling cost, making it better for short runs or designs still in development. Finalize your design before committing to dies, since tooling changes are expensive.

The most common mistakes in sheet metal stamping are holes placed too close to edges, small hole diameters that do not account for material thickness, and tight radii. These features look simple in CAD but require secondary operations. Redstone reviews every design for manufacturability before quoting.

Redstone applies a critical-to-quality inspection approach. Every dimension on your drawing is ballooned into an inspection template, with extra rigor on the driving dimensions that control assembly fit. We use CMM, height gauges, thread gauges, and optical measurement depending on the feature.

The facility only sees that Redstone is producing the parts, not the end customer or industry. For sensitive projects, Redstone can split production across multiple facilities so no single facility receives the full drawing set.

Metal stamping works best for parts formed from sheet metal or strip stock through operations like blanking, punching, and drawing. If your part has geometry that cannot be formed from flat stock, a casting process may be a better fit. Our team recommends the right process based on your geometry and volume.
