Top Automotive Stamping Tooling Suppliers in China

Technology or Service	What It Covers	Typical Automotive Applications	Common Deliverables and Checks
Progressive Die Design and Manufacturing	Integrated die stations perform successive operations, such as piercing, bending, forming, and part cut-off, as strip material advances through the tool.	High-volume production of small and medium stamped components, including brackets, reinforcements, and electrical or seat hardware.	Die layout, strip layout, tool design, tryout support, and checks for part dimensions, burrs, and repeatability.
Transfer Die Systems	Parts are moved between forming stations by mechanical or robotic transfer equipment, allowing multiple operations on larger or deeper parts.	Structural panels, chassis components, and other parts that are not suited to conventional progressive-strip production.	Station and transfer concepts, die sets, operation sequencing, and trial-run checks for part handling and forming consistency.
Tandem and Line Dies	Separate dies carry out individual operations in a press line, with parts transferred between presses or stations.	Large body panels and components requiring several forming, trimming, piercing, or flanging operations.	Individual dies, process planning, line integration support, and dimensional inspection of trial parts.
3D CAD and Die Simulation	Digital design and forming analysis help assess material flow, thinning, wrinkling, springback, and potential forming issues before production tooling is finalized.	Complex body-in-white panels, high-strength steel parts, and components with demanding geometry.	3D tool designs, forming analysis reports, process recommendations, and design revisions based on simulation results.
High-Strength Steel Forming	Tool and process design accounts for the higher strength and springback behavior of advanced high-strength steels and other demanding sheet materials.	Safety-related structural parts, reinforcements, pillars, and chassis components.	Material-specific process plans, compensation strategies, trial results, and dimensional verification against supplied specifications.
Aluminum Sheet Forming	Forming methods and tool surfaces are selected to address aluminum’s material behavior and reduce risks such as surface marking and cracking.	Lightweight body panels and structural components made from sheet aluminum.	Material and lubrication recommendations, forming trials, surface-condition checks, and dimensional inspection.
Tryout, Sampling, and Tool Tuning	Press trials are used to evaluate the tooling and adjust forming conditions, clearances, or tool geometry as needed.	New dies, transferred tools, and production changes that require confirmation before release.	Trial parts, issue lists, adjustment records, and sample inspection results. Scope depends on the agreed project plan.
Metrology and Dimensional Inspection	Parts and tooling features are measured against engineering drawings or agreed inspection requirements using suitable measurement equipment.	Prototype, pre-production, and production validation for stamped components.	Measurement reports, dimensional comparison data, and documentation of nonconformities where applicable.
Tool Repair, Maintenance, and Refurbishment	Inspection, repair, replacement, or adjustment of worn or damaged die components to support continued production.	In-service tooling requiring corrective work, scheduled maintenance, or relocation support.	Repair plans, replacement components, maintenance records, and post-repair trial or inspection support.
Engineering Change and Localization Support	Tooling or process updates are managed when part designs, materials, manufacturing locations, or customer requirements change.	Model-year updates, design revisions, and production transfer projects.	Change assessments, revised tool data, updated documentation, and validation samples as defined by the project.
