Automotive parts consolidation is changing the discussion around body-in-white manufacturing. Gigacasting has drawn attention by replacing assemblies of many stamped and joined components with larger cast structures, but steel stamping is also moving toward fewer, larger and more integrated parts.
Research presented in 2026 by WorldAutoSteel and at AISI's Great Designs in Steel shows that advanced high-strength steels, press-hardened steels, tailored material strategies and increasingly sophisticated stamping simulation are expanding the possibilities for consolidated automotive structures. This does not mean stamping or gigacasting will universally replace the other; it means OEMs now have more architectural choices.
The industry figures discussed below are based primarily on WorldAutoSteel's 2026 Parts Consolidation Study, commissioned with Ricardo Engineering, and technical topics presented at AISI Great Designs in Steel 2026. These findings describe specific engineering studies and should not be interpreted as universal production results or Changdong performance guarantees.
Traditional automotive body structures can contain many individual stampings joined by spot welding, riveting, adhesives or other assembly processes. Each additional component introduces tooling, fixtures, handling, dimensional stack-up and production-management requirements.
Parts consolidation attempts to redesign several smaller components into fewer, larger structural parts. The objective is not simply to reduce the number of stampings. Engineers must also evaluate structural performance, manufacturability, joining strategy, repairability, investment, material utilization and the effect of larger parts on the production system.
WorldAutoSteel commissioned Ricardo Engineering to investigate whether AHSS could support greater parts consolidation in a front body structure based on the Steel E-Motive concept. The project used 3D CAD modelling and stamping simulation to assess both structural design and manufacturing feasibility.
| Study Result | WorldAutoSteel 2026 Finding |
|---|---|
| Front structure part count | 38 parts reduced to 25 parts, a 34% reduction in the study design |
| Weight | 8% reduction for the redesigned front body structure |
| Piece cost | 10% reduction estimated for the studied front structure |
| Manufacturing investment | Approximately US$21 million reduction estimated for the specific front-structure manufacturing model |
| Structural performance | Designed to remain comparable with the Steel E-Motive baseline |
These numbers should be read as results from one engineering study, not as general savings that every stamping project can achieve. More important for stamping-die engineering is how the consolidation was achieved: multiple existing components were redesigned into larger hot- and cold-stamped parts, with some concepts combining two to six previous stampings into one component.
Large aluminum castings demonstrated that vehicle manufacturers could reconsider the traditional architecture of many small stamped and welded parts. This shifted the engineering question from “How do we manufacture every existing component?” toward “How many components are actually necessary?”
For steel stamping, the response is not to copy the casting process. Instead, the opportunity is to redesign stamped structures using newer AHSS grades, press-hardened steel, tailored blanks, larger forming operations and more sophisticated process simulation so that fewer stamped parts can perform functions previously divided among several components.
WorldAutoSteel's study included five new consolidated subassembly concepts. One example changed a five-component strut-top assembly into a single hot-stamped component, while other concepts consolidated several stamped parts through different AHSS and tooling strategies.
AISI's 2026 Great Designs in Steel program reinforced the same broader direction. One technical project specifically evaluated AHSS- and UHSS-dominant steel front-end designs as alternatives to a generic aluminum giga-casting architecture. The project evaluated crash and stiffness targets, manufacturing feasibility, part consolidation, cost and sustainability rather than treating material substitution as a simple one-variable comparison.
Larger consolidated stampings usually place more demands on the material. A component may need high structural strength in one region while also requiring sufficient formability for deeper draws, radii, embossments or complex transitions elsewhere.
Modern AHSS, UHSS and press-hardened steel give engineers a wider range of strength and formability combinations. Tailor welded blanks can extend this approach by combining different steel grades or gauges within one blank so that material properties are placed where they are needed.
However, higher material strength also increases tooling challenges. Cutting loads, springback, edge cracking, galling, die wear and dimensional stability become more important as part size and structural integration increase.
| Tooling Requirement | Why Consolidation Increases the Requirement |
|---|---|
| Larger tooling envelope | Combining several components can create larger blanks, forming surfaces and trimming boundaries. |
| More complex forming sequence | One integrated component may combine geometry previously distributed across several simpler stampings. |
| Higher CAE dependence | Material flow, thinning, splitting, wrinkling and springback require earlier simulation and iteration. |
| Trim and pierce complexity | Larger three-dimensional parts create longer trim lines, more pierced features and more demanding scrap discharge. |
| Springback control | High-strength materials and larger structural geometries increase the importance of compensation and restriking. |
| Validation | A dimensional deviation in one consolidated component can affect several downstream assembly interfaces. |
The 2026 WorldAutoSteel work used stamping simulation extensively to evaluate manufacturing feasibility. Areas such as thinning, splitting, material flow and process parameters had to be considered while larger single-piece concepts were developed.
This reflects a broader tooling trend: as one stamped component carries more geometry and structural function, early DFM and CAE decisions become more valuable. Draw depth, radii, drawbeads, binder force, lubrication, material model and springback compensation can influence whether consolidation remains manufacturable.
Gigacasting and consolidated steel stamping use fundamentally different manufacturing systems. Their economics and engineering trade-offs depend on production volume, vehicle architecture, available capital equipment, part geometry, material strategy, joining operations, repair strategy and existing factory infrastructure.
Even the 2026 studies that demonstrate steel alternatives use specific baselines, assumptions and cost models. The useful conclusion is therefore not that stamping has “defeated” gigacasting. The more defensible conclusion is that advanced steel stamping remains an active parts-consolidation route, and vehicle manufacturers can evaluate both architectures according to program-specific requirements.
Parts consolidation may simplify the vehicle assembly structure while making each individual stamping more technically demanding. A larger consolidated component can require a larger die, more forming stages, higher press loads, more complex trimming and tighter control of springback and dimensional interfaces.
For stamping-die suppliers, the trend therefore shifts engineering value upstream toward DFM, CAE, material understanding, die design, tryout correction and dimensional validation rather than simply machining a larger tool.
The direction visible in 2026 industry research suggests that automotive tooling suppliers will increasingly need to support larger and more integrated stamped structures while working with stronger materials and more simulation-driven development.
Important capabilities include large-tool engineering, AHSS forming experience, CAE, springback compensation, trim-and-pierce engineering, suitable press tryout and dimensional validation. For projects within Changdong's verified tooling and equipment conditions, these capabilities can be combined during DFM, die development, tryout correction and sample validation.
Automotive parts consolidation is the redesign of multiple vehicle components into fewer, larger and more integrated parts in order to simplify vehicle architecture and manufacturing.
Gigacasting is one parts-consolidation route, while AHSS, UHSS, press-hardened steel, tailored blanks and advanced stamping processes are enabling another route based on larger integrated steel stampings.

Not universally. Vehicle manufacturers can evaluate casting, stamping and mixed architectures according to volume, structure, material, investment, manufacturing infrastructure and program requirements.
The 2026 WorldAutoSteel feasibility study demonstrated that selected AHSS and press-hardened steel structures could consolidate several existing components into fewer larger stampings. Actual feasibility remains vehicle- and project-specific.
Larger integrated parts can combine more geometry and structural functions in one component, increasing requirements for material flow, die size, forming sequence, trimming, springback compensation and dimensional validation.
CAE can help evaluate thinning, splitting, wrinkling, material flow and springback before tooling is finalized. Physical tryout and sample validation are still required to confirm actual manufacturing performance.
