An automotive trim die removes excess material from a drawn or formed sheet metal part to establish the final edge profile. A trim and pierce die may also create holes, slots, notches or reference features during the same operation or through coordinated tooling stages.
Dongguan Changdong Tool & Die Co., Ltd. designs and manufactures custom automotive trimming dies, pierce dies and trim-pierce tooling for suitable structural parts, reinforcement components, brackets and formed panels. Each project is reviewed according to the part drawing, material grade, sheet thickness, trim-line geometry, piercing requirements and customer press conditions.
Review of final edge geometry, cutting direction, staged trimming requirements and part support.
Piercing of holes, slots, notches and selected locating features according to drawing requirements.
Suitable press equipment supports die spotting, cutting adjustment, scrap-flow review and sample production.
Trimmed profiles, holes, datums and selected dimensions are inspected using suitable measurement methods.
An automotive trim-pierce die locates a previously drawn or formed component, supports its three-dimensional shape and cuts the final perimeter or selected edge sections. Piercing punches may then produce holes, slots or notches required for later welding, fastening, assembly or locating operations. Depending on part geometry and load distribution, trimming and piercing may be completed in one die or divided into separate operations.
| Capability | Changdong Reference | Project Conditions |
|---|---|---|
| Sheet thickness | Approximately 0.3–12 mm | Subject to material grade, cutting perimeter, geometry and press review |
| Press capacity | 45T–800T | Press matching also considers bed size, shut height and pressure center |
| Maximum die length | Approximately 4,200 mm | Depending on die structure, weight and equipment conditions |
| Maximum product size | Approximately 1,200 mm | Subject to part structure, locating method and tooling route |
| Selected precision features | Approximately 0.03 mm may be achievable | Subject to feature type, material, process and inspection method |
| Typical T0 timing | About 35 days | After final drawings and technical requirements are confirmed |
A drawn automotive component may contain springback and local shape variation before trimming. The die must locate the part using stable datums and support areas without forcing it into an incorrect position. Trim-line accuracy depends on the relationship between the formed surface, locating features, cutting inserts and the approved sample condition.
Clearance is selected according to material grade, thickness, tensile strength, edge requirement and cutting direction. Insufficient clearance may increase cutting load and edge chipping, while excessive clearance may increase rollover and burr size. The required burr direction should be confirmed during drawing review. General principles are explained in the stamping die clearance and burr control guide.
A long three-dimensional trim line may not cut at the same time across the complete part. Shear angles and staged cutting can help manage peak load, but they may also introduce lateral force and uneven die loading. The tooling structure, guide system, insert support and pressure center must be reviewed together with the customer press.
Trim scrap, pierced slugs and cut-off sections must leave the tooling without interfering with the part, sensors or moving components. Scrap chutes, die relief, ejectors and discharge direction are selected according to scrap size, die orientation and press conditions. Unstable scrap flow can damage the part or interrupt repeated production.
Replaceable cutting inserts and punches may simplify maintenance in high-wear areas. Selected inserts, punches and cutting edges can be heat-treated to approximately HRC 58–60 depending on tool steel, part material and stamping conditions. TD or Super TD treatment is available for selected in-house die components when required by the project.
Trim and pierce tooling for suitable reinforcement components, structural supports and formed automotive panels.
Final-edge trimming and piercing of mounting holes, slots and locating features for formed bracket components.
Post-drawing trimming, notching and piercing for suitable three-dimensional sheet metal components.
A trim die cannot be developed only from a flat blank or final two-dimensional perimeter. The incoming part shape is created by the drawing or forming operation, including its springback, surface variation and locating condition.
For this reason, trim-line development should be coordinated with the drawing, forming, flanging and restriking process. Changes made to an upstream forming die may affect the location and stability of the part in the trim-pierce tool.

Dongguan Changdong Tool & Die Co., Ltd. designs and manufactures automotive trim dies, pierce dies and trim-pierce tooling with DFM, machining, assembly, 45T–800T press tryout and sample-validation support.
Changdong manufactures custom stamping dies and stamped metal parts. It does not sell stamping press machines, standard retail cutting dies or laser-cutting equipment.
A trim die cuts the final outer edge or removes excess material, while a pierce die creates holes, slots or internal cutouts. Both operations may be integrated into one tool when geometry and load conditions permit.
Yes, for suitable parts. Complex trim lines, high cutting loads, part deformation or scrap-flow risks may require separate or staged operations.
The trimmed sample can be checked against approved datums, profiles, dimensions and checking-fixture or CMM requirements, depending on the project.
Provide the final part drawing, formed-part data, material grade, thickness, trim-line and hole requirements, burr direction, expected volume and available press information.
Send the formed-part drawing, material specification, trim line, piercing requirements and press information for a project-specific tooling review.
