Tier-1 Vacuum Thermoforming for Thailand's Automotive Industry

Large-format thermoformed components manufactured to automotive standards — build-to-print, under IATF 16949 quality systems, with manufacturing heritage since 1989.

What We Do

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.

Build-to-Print Manufacturing

Send us your drawings or CAD. We handle process design, tooling coordination, PPAP submission and serial production to your spec.

Automotive-Grade Quality System

IATF 16949 and ISO 14001 certified. APQP, PPAP, full lot traceability — the documentation discipline OEM programs require, applied to every industry we serve.

Tooling & Development Support

In-house tooling capability through our parent company group: CNC machining and tool making under one roof shortens iteration loops.

Why Vacuum Thermoforming?

If your part is large, your volumes are low-to-mid, and your timeline is tight — thermoforming usually wins. Here's why.

The Process

  1. Heat plastic sheet heated to forming temperature
  2. Form vacuum draws the sheet onto a single-sided mold
  3. Cool part solidifies on the mold
  4. Trim CNC trimming to final geometry
Vacuum Thermoforming vs Injection Molding
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.
