Thermoforming heats a plastic sheet until pliable, drapes it over a mould, then uses vacuum pressure to form and eject a shaped part.
The process — also called vacuum forming — has been in industrial use since the 1930s and remains one of the most cost-effective methods for shaping thermoplastic materials at scale.
Step | Stage | What Happens |
|---|---|---|
1 | Heat | A flat thermoplastic sheet is clamped and heated until it becomes pliable (typically 120–200°C depending on material). |
2 | Drape | The softened sheet is lowered over or raised onto a mould (tool). |
3 | Vacuum | Air is evacuated between the sheet and mould, pulling the plastic into the mould contours. |
4 | Cool & Eject | The formed sheet cools, hardens, and is ejected from the mould. |
5 | Trim | Excess plastic is trimmed away using a cutter or router to produce the finished part. |
One key advantage is tooling speed: a vacuum forming mould can be produced in hours using 3D-printed or CNC-machined tools, compared to weeks for injection moulding tooling.
Thermoforming offers a lower tooling cost and faster turnaround than injection moulding, with better surface finish and higher output than 3D printing.
Factor | Thermoforming | 3D Printing | Injection Moulding |
|---|---|---|---|
Tooling Cost | Low (3D-printable moulds possible) | None (toolless) | Very high (steel or aluminium tooling) |
Tooling Lead Time | 1–3 days | None | 4–12 weeks |
Part Size | Up to 2440 × 1220 mm (Formech) | Limited by print bed | Limited by mould size |
Surface Finish | Smooth, printable | Layered/textured | High gloss (tool-dependent) |
Minimum Quantity | Low (1+ units) | Low (1 unit) | High (1,000+ units typical) |
Material Options | ABS, PETG, PVC, HIPS, Acrylic, PC | PLA, ABS, Resin, Nylon | Wide (tool-specific) |
Digitally Printable Surface | Yes (with TF-compatible inks) | Limited | Yes (post-moulding) |
Note: Thermoforming is optimal when tooling cost, delivery time, and the ability to combine print-and-form in a single workflow are key decision factors.
Vacuum-formed parts are used across packaging, retail display, aerospace, automotive, set design, and point-of-sale industries worldwide.

Formech machines are in active use at Apple, Google, Disney, Dyson, McLaren, BE Aerospace, Ferrero Rocher, 3M, DuPont, and Volkswagen Group, among others.
Formech desktop machines bring industrial vacuum forming into lab, studio, and classroom environments with a compact footprint.
The desktop range is suited to first-time thermoforming users, industrial designers, R&D teams, students, and small production runs where space is limited.
Model | Forming Area | Best For |
|---|---|---|
Formech Compact Mini | Small (bench-top) | Education, concept prototyping, material testing |
Formech 450 DT | 450 mm × 300 mm | Design studios, small-batch packaging prototypes |
Formech 508 DT | 508 mm × 457 mm | Mid-scale prototyping, lab environments, SMEs |
All desktop models are available in India through Arrow Digital Pvt. Ltd. and are backed by local technical support.
Formech large format machines handle forming areas up to 2440 × 1220 mm — suitable for full-panel automotive trim, large signage, and retail display production.
Model | Forming Area | Max Sheet Size | Primary Applications |
|---|---|---|---|
Formech 1372 | 1372 × 762 mm | 1524 × 914 mm | Retail POS, signage, packaging |
Formech 1250 | 1250 × 750 mm | 1400 × 900 mm | Interior panels, display units |
Formech 1500 | 1500 × 1000 mm | 1650 × 1150 mm | Automotive trim, aerospace panels |
Formech 2440 | 2440 × 1220 mm | 2590 × 1370 mm | Large-scale signage, film & theatre set pieces |
Formech large format machines are used in India for transit advertising panels, illuminated retail signage, automotive component prototyping, and film set fabrication.
Digitally printing onto a thermoplastic sheet before vacuum forming converts flat 2D graphics into dimensional, illuminated 3D display objects.
This print-and-form workflow is used by PSPs and display fabricators to produce premium retail displays, illuminated signage, and branded POS units — at far lower tooling cost than traditional injection moulding.
Step | Process | Equipment / Material |
|---|---|---|
1 | Digital print | Print the design onto thermoformable sheet using EFI H1625-SD with EFI TF inks |
2 | Mould preparation | Produce the forming mould via Massivit 3D printer or CNC machining |
3 | Vacuum forming | Form the printed sheet over the mould using a Formech large format machine |
4 | Trimming | Trim formed part using Kongsberg cutting table or manual router |
5 | Finishing | Apply EFI TF outdoor coatings for UV, scratch, and weather resistance |
EFI TF inks are formulated to stretch with the plastic sheet during forming without cracking or colour shift — a critical requirement for outdoor-rated thermoformed signage.
Common questions from Indian print shops, display fabricators, and industrial buyers considering Formech vacuum forming equipment.
Vacuum forming is a subset of thermoforming. In vacuum forming, a heated plastic sheet is shaped using vacuum suction alone. Some advanced thermoforming processes also apply positive air pressure to achieve sharper detail — this is sometimes called pressure forming or twin-sheet forming.
For retail signage, POS displays, and illuminated lettering, the Formech 1372 or Formech 1500 are the most commonly used models. The Formech 2440 is suited to extra-large-format production such as full transit panel displays or large-format set pieces.
Yes. Using thermoformable inks (such as EFI TF inks) on compatible sheets, you can digitally print a flat graphic and then vacuum form it into a 3D shape. The inks are formulated to stretch with the plastic without cracking. EFI H1625-SD printers are compatible with this workflow.
Formech machines are compatible with ABS, HIPS, PETG, Acrylic (PMMA), PVC, Polycarbonate (PC), HDPE, and many other thermoplastic sheet materials. Material suitability depends on forming temperature and the specific machine model.
Formech machines are distributed in India exclusively by Arrow Digital Pvt. Ltd. Arrow Digital provides equipment, installation, training, and ongoing technical support across India.
For large parts (above 500 mm in any dimension), thermoforming is typically faster and more cost-effective than 3D printing. Thermoforming also produces a smoother, paintable, and digitally printable surface. 3D printing remains better suited to highly complex geometries in small quantities.
