Large-Part Vacuum Thermoforming
Forming large, complex geometries that are impractical or uneconomical to injection-mold — door trims, floor coverings, under-body panels, liners and beyond.
Tier-1 automotive supplier · Pathum Thani, Thailand
Large-format thermoformed components manufactured to automotive standards — build-to-print, under IATF 16949 quality systems, with manufacturing heritage since 1989.
Forming large, complex geometries that are impractical or uneconomical to injection-mold — door trims, floor coverings, under-body panels, liners and beyond.
Send us your drawings or CAD. We handle process design, tooling coordination, PPAP submission and serial production to your spec.
IATF 16949 and ISO 14001 certified. APQP, PPAP, full lot traceability — the documentation discipline OEM programs require, applied to every industry we serve.
In-house tooling capability through our parent company group: CNC machining and tool making under one roof shortens iteration loops.
If your part is large, your volumes are low-to-mid, and your timeline is tight — thermoforming usually wins. Here's why.
| Criterion | Vacuum Thermoforming | Injection Molding |
|---|---|---|
| Tooling cost | Single-sided mold — a fraction of the investment | Matched steel tooling — high upfront cost |
| Tooling lead time | Typically 2–3 months | Typically 3–6 months, depending on size & complexity |
| Part size | Excellent for large panels & deep draws | Limited by press size; large parts get very expensive |
| Volume sweet spot | Low to mid volume | Very high volume |
| Design changes | Fast, low-cost tool modification | Expensive and slow to modify |
| Per-part economics | Amortized tooling keeps total cost-per-part lower at low/mid volume | Wins only when volume is high enough to absorb tooling |
At low-to-mid volumes, amortized tooling cost dominates part economics. That's where thermoforming delivers the lowest total cost — without compromising on automotive-grade quality.
Beyond build-to-print, we are developing our own NVH (Noise, Vibration, Harshness) material technologies — and we're open to co-developing them with partners.
