Metal Stamping & Deep Drawing Capabilities

Chutes.png

OEMs sourcing stamped and deep-drawn components need a metal stamping manufacturer that delivers more than press capacity. They need an engineering and manufacturing partner with the application knowledge, tooling discipline, and production scale to support complex, multi-platform programs — from progressive stamping and deep drawing manufacturing through welding, finishing, and assembly-ready delivery.

 

CS Cosmos STIHL has been that partner since 1972. For more than 50 years, we have engineered and manufactured precision-stamped components, deep-drawn parts, and finished assemblies for OEMs in the outdoor power equipment, small engine, and commercial equipment markets. Our background reflects the Tier 1 supplier capability that enterprise procurement and engineering teams expect when qualifying a long-term metal stamping manufacturer.

OEM Metal Stamping Manufacturer for Complex Components & Assemblies

OEM-grade stamping is fundamentally different from commodity job-shop work. It requires dimensional repeatability across production volumes, validated processes that hold tolerances lot after lot, scalability to match seasonal and multi-year program demands, and documentation that satisfies procurement and quality team requirements from RFQ through ongoing supply.

 

CS Cosmos STIHL is an engineering and manufacturing partner, not a parts broker. We take programs from initial concept through prototype validation, pilot production, full-volume manufacturing, and continuous improvement — providing the full-lifecycle support that OEMs need when qualifying a metal stamping manufacturer for performance-critical and structural components.

Industries & Equipment Platforms We Support

Our stamping and deep drawing manufacturing experience is concentrated in the application-intensive segments where component performance directly affects equipment reliability:

  • Outdoor power equipment: Zero-turn mowers, garden tractors, ride-on platforms, handheld tools, and compact utility equipment.

  • Small engine platforms: Mufflers, exhaust systems, structural components, and engine-adjacent assemblies for commercial and industrial engine OEMs.

  • Battery-powered equipment: Stamped housings, enclosures, trays, and structural components for electrified OPE platforms.

  • Generators, pumps, and stationary engines: Components requiring durability under continuous duty and harsh environmental exposure.

Precision Metal Stamping Capabilities

Our stamping operations produce the high-volume OEM components where dimensional accuracy and repeatability are non-negotiable. Progressive die stamping, compound die operations, and secondary-operation stamping are all performed in-house, supported by tooling maintenance and quality systems designed for long-running OEM programs.

 

Scale and consistency go together. Our press capacity and process discipline deliver the dimensional control required for automated and semi-automated assembly environments — verified through in-process inspection at each manufacturing stage.

Stamped Component Types

Our stamping scope covers both structural and cosmetic components: Brackets, frames, mounts, guards, housings, and panels are produced to the tolerances required for consistent assembly line fit. Stamped parts designed for downstream welding and assembly are manufactured with the joint preparation, edge quality, and dimensional control that welding operations require.

Tooling, Die Design, & Production Efficiency

Tooling strategy directly affects part quality, scrap rates, and cycle time. Our tool and die maintenance philosophy is built around preventive maintenance schedules, in-process monitoring, and rapid response to wear indicators — protecting dimensional consistency across long production runs.

 

DFM is applied at the tooling stage. Geometry optimization, material utilization, and forming strategy are evaluated before tooling is committed. The result is lower scrap, faster cycle times, and more consistent parts across the life of the program.

Deep Drawing Manufacturing for OEM Components

Deep drawing manufacturing produces seamless, high-strength formed components that fabricated or multi-piece alternatives cannot match. The process draws flat sheet metal into three-dimensional shapes without seams or joints — eliminating weld paths, reducing leak risk, and delivering superior strength-to-weight ratios through strain hardening.

 

At CS Cosmos STIHL, metal deep drawing manufacturing is a core capability, not a specialty add-on. Our deep drawing operations are integrated into the same production flow as our stamping, welding, and finishing operations — delivering complete, finished components from a single source.

What Is Metal Deep Drawing Manufacturing?

Deep drawing transforms flat sheet metal into hollow, three-dimensional forms by drawing the material radially into a die cavity. Forming depth, material flow characteristics, blank holder pressure, and die geometry all influence the final part. Typical deep drawn geometries include cylindrical shells, cup-shaped housings, oval enclosures, and asymmetric formed parts.

 

OEMs should specify deep-drawn components when the application demands seamless construction, structural rigidity, or complex geometry. Parts that would otherwise require multiple formed pieces welded together are strong candidates for metal deep drawing manufacturing — reducing part count, eliminating weld-related failure modes, and improving dimensional consistency.

Deep Drawn Component Applications

Our deep drawing manufacturing experience spans the component types most common in outdoor power equipment and small engine platforms:

  • Muffler shells and exhaust housings: Seamless deep-drawn shells provide the structural integrity and acoustic performance that exhaust applications demand.

  • Cylindrical and cup-shaped structural components: Load-bearing formed parts where strain-hardened strength and dimensional consistency are critical.

  • Enclosures, covers, and formed housings: Battery pack enclosures, protective covers, and component housings where seamless construction improves durability and reduces leak paths.

Integrated Welding, Finishing, & Assembly

End-to-end manufacturing under one roof is what separates CS Cosmos STIHL from generalist metal stamping manufacturers. Stamping, deep drawing, welding, surface finishing, and assembly all operate within a single facility and a single quality system — reducing cost, lead time, and quality risk for OEMs managing complex, multi-platform supply chains.

Welding Capabilities Supporting Stamped & Deep Drawn Parts

Spot welding and MIG welding produce multi-part assemblies from stamped and deep-drawn components. Structural and cosmetic weld requirements are addressed through fixture strategy, weld parameter control, and operator qualification. Fixtures are designed for repeatability, ensuring consistent joint quality across high-volume production runs.

Surface Finishing & Coatings

Plating, black oxide, high-temperature paint, and corrosion-resistant coatings are integrated into the production flow. Finish selection is driven by operating environment, durability requirements, and appearance standards. Finishing operations run in-line with stamping and welding — eliminating the coordination delays and quality risks that come with outsourcing finish work to third-party suppliers.

Assembly-Ready Subcomponents

Kitted and subassembled components reduce OEM handling and assembly complexity. We deliver stamped, welded, and finished subassemblies packaged for direct integration into OEM production lines — reducing inbound part counts, incoming inspection steps, and line-side staging time. This approach supports lean manufacturing objectives and just-in-time delivery requirements for enterprise OEM programs.

Engineering Support for Manufacturability

Early-stage collaboration with OEM engineering teams is where the highest cost and performance gains are captured. CS Cosmos STIHL’s engineering team works alongside OEM design and procurement groups from initial concept review through production launch, providing the DFM expertise that turns drawings into producible, cost-effective components.

Design for Manufacturability (DFM) in Metal Stamping

Geometry optimization targets formability and tool life. Material selection balances strength, thickness, formability, and cost for each application. Reducing secondary operations through design changes — such as integrating piercing, forming, and trimming into the progressive die sequence — lowers per-unit cost while maintaining or improving part performance.

Transitioning From Fabricated to Stamped or Deep Drawn Parts

Consolidating multi-piece weldments into single stamped or deep-drawn components is one of the most effective cost-down and weight-reduction strategies available. Fewer parts mean fewer welds, fewer potential failure points, and lower assembly labor. CS Cosmos STIHL’s engineering team evaluates existing fabricated designs for deep drawing manufacturing or progressive stamping conversion, managing the redesign without disrupting active production programs.

Materials, Tolerances, & Quality Expectations

Procurement and quality teams need confidence that a metal stamping manufacturer can hold tolerances, control processes, and document results consistently. CS Cosmos STIHL’s ISO-aligned quality system and decades of OPE-focused manufacturing experience provide that confidence across high-volume, long-running OEM programs.

Material Options and Thickness Ranges

Common material families include cold-rolled steel, stainless steel, and high-strength low-alloy (HSLA) grades. Material selection is driven by the application’s structural, corrosion resistance, and formability requirements. Thickness is optimized during DFM to balance strength, weight, and material cost. Deep drawing applications require materials with specific elongation and formability characteristics to achieve target draw depths without tearing or wrinkling.

Tolerances, Inspection, & Process Control

Dimensional control for stamped and deep-drawn components is maintained through validated tooling, in-process inspection, and statistical process monitoring. Critical features are verified at defined checkpoints throughout the manufacturing process. Repeatability across high-volume programs is documented and traceable, supporting PPAP-level deliverables and ongoing supplier performance reviews.

Manufacturing Scale & OEM Program Readiness

Long-term OEM programs require a metal stamping manufacturer with the capacity, planning discipline, and documentation systems to support multi-year supply commitments. CS Cosmos STIHL’s 9M+ annual unit capacity and seasonal demand planning expertise — developed through decades of serving the outdoor power equipment market — provide that foundation.

High-Volume Production & Capacity Planning

Managing ramps and volume changes is a core competency. Capacity allocation, material procurement, and production scheduling are planned around seasonal demand patterns and multi-program production calendars. Consistent delivery performance is maintained even when multiple OEM programs are running simultaneously.

Documentation & Supplier Qualification Support

Drawings, revision control, inspection reports, and process validation records are maintained to OEM standards. Our documentation systems support customer audits, supplier onboarding processes, and ongoing qualification requirements. Long-term supplier reliability is demonstrated through consistent quality metrics, on-time delivery performance, and proactive program management.

When to Choose Metal Stamping vs Deep Drawing

Understanding when to specify stamping versus deep drawing manufacturing helps OEM engineers and sourcing teams make better sourcing decisions. The right process depends on part geometry, structural requirements, production volume, and cost targets.

Metal Stamping Use Cases

Progressive and compound die stamping is the right choice for flat or lightly formed components with multiple features. Brackets, mounts, panels, guards, and structural reinforcements that require tight tolerances across pierced, formed, and trimmed features are well-suited to progressive stamping. High-volume, cost-sensitive programs benefit from the speed and material efficiency of progressive die operations.

Deep Drawing Use Cases

Deep drawing manufacturing is specified when the application requires cylindrical, cup-shaped, or deeply formed geometry. Seamless construction provides superior strength and rigidity compared with fabricated alternatives. Eliminating welds and seams reduces leak paths — critical for exhaust components, fluid-handling housings, and sealed enclosures. When part consolidation can replace a multi-piece weldment with a single deep-drawn component, the cost and quality advantages are significant.
