Thermoformed Automotive Parts
Trim for specialty vehicles:tooling that pays at a few hundred sets.
Thermoformed Automotive Parts are shaped from heated plastic sheet. FUNYO forms single parts up to 2600 × 1600 × 600 mm from sheet up to 15 mm; housings commonly use 8–10 mm. Forming tools take about 1–3 weeks and cost under 1/10 of a comparable injection mold.

Thermoforming compared with other processes
Keep model differences
in a clear revision table.
When one platform serves several models, tools, CNC programs and appearance standards are managed by revision:
Send drawings, answer in 2 working days| How we handle it | Confirmed by | |
|---|---|---|
| Shared platform | Parts with the same shape, split and datums share one tool | Models, drawings and a sample set |
| Interface differences | Openings and left/right differences handled in CNC programs | Per-model machining and assembly records |
| Matching appearance | Color, texture and gloss to one master sample | Shared appearance standard |
| Service parts | Tools and programs kept by model and part number | Revision traceability |
Automotive and rail material specifications differ and are confirmed per project.
Assembly, access and interface design
New model?
Start with what can be shared.
Sharing doesn't mean forcing models to be identical. It means separating the contours that truly match from the interfaces that change:
Main contour and split
Compare body contours, splits and materials; what matches goes into one tool.
Needed: surface models for each variant
Model interfaces
Openings, accessories and left/right differences are handled with CNC programs and fixtures.
Confirmed: CNC program per model
Mounting datums
Trimming and holes reference the vehicle mounting points; seams are checked on the vehicle.
Confirmed: on-vehicle sample and seam record
Sheet materials and project requirements
Where it sits
decides what the material must answer.
8–10 mm sheet is typical, up to 15 mm.
Heavy-gauge thermoforming| Interior trim | ABS is most common; color and texture approved to a master sample. |
|---|---|
| Exterior covers | PC or ABS for impact; a weatherable grade for sun exposure, checked on samples. |
| Rail interiors | Specific fire and smoke standards apply; the material is specified per project with certificates. |
| Parts handling | HDPE, PP or static-dissipative grades, chosen by part and process. |
We don't claim vehicle or rail certifications that haven't been confirmed.
Factory, CNC trimming and inspection
Forming, trimming, inspection:one plant in Zhuhai.
FUNYO started in precision machining in 2004 and has been thermoforming since 2013. Heavy-gauge forming, CNC trimming and dimensional inspection all happen in our Doumen plant, and we machine our own forming tools, so revisions don't wait on outside shops.

Thermoforming for automotive & transportation: FAQ
Bring the model differences.
We'll find what can be shared.
Send the models, mounting areas and current platform; if neighboring trim exists, include its appearance and seam requirements.
FAQ
Can thermoforming be evaluated for automotive & transportation at 300–3,000 units per year?
300–3,000 units is a quoting scenario, not a break-even threshold. Compare part size, assembly, material, tooling and unit costs before selecting a process.
What size and sheet thickness are available for automotive & transportation?
The maximum single part is 2600 × 1600 × 600 mm, with sheet up to 15 mm. Housings commonly use 8–10 mm sheet. Finished dimensions depend on geometry and trimming allowance.
Which sheet grades should I specify for automotive & transportation?
ABS, PC, PVC, PETG and PP can be formed. PC or PETG can be evaluated for transparent parts. PE, weatherable, flame-retardant and antistatic grades are sourced and sampled for the project.
How long does tooling for automotive & transportation take?
Forming tooling costs under 1/10 of a comparable injection mold and takes about 1–3 weeks. Comparable injection molds take about 6–10 weeks. Confirm the scope against the drawing and material.
What should I send for a 2-working-day thermoforming assessment for automotive & transportation?
Send drawings or photos, dimensions, annual and first-order quantities, assembly interfaces and operating conditions. We respond in 4 hours and provide the applicability assessment and comparison quote in 2 working days.
