# Thermoformed Electronics Housings

Years of supplying electronics leaders. Now instrument housings too.

Thermoformed Electronics Housings 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.

- **Max. part size**: 2600×1600×600 mm — L × W × H, formed in one piece
- **Max. sheet thickness**: 15 mm — 8–10 mm is typical for housings
- **Tooling lead time**: 1–3 weeks — vs. about 6–10 weeks for a comparable injection mold
- **Tooling cost**: \<1/10 — of a comparable injection mold

- **Electronics experience**: In electronics supply chains since 2010
- **Precise openings**: CNC-cut to component drawings
- **Clean and ESD-aware**: Cleanroom and permanent anti-static materials

## Thermoformed parts for electronics & advanced equipment

Electronics parts that suit thermoforming:

- Electronic test
- Precision inspection
- Specialist instruments
- Precision parts handling

### Instrument housings, upper and lower shells

Large curves in one piece; parting lines and datums fixed before tooling.

### Bezels and control panels

Display, button and connector openings cut to component drawings.

### Module service covers

Split along module removal paths, so service removes one panel.

### Precision parts trays

Thin-gauge precision trays formed in our cleanroom and DI-washed before delivery.

## Thermoforming compared with other processes

Instrument housings are often asked to solve electrical functions “on the side”. What a formed part can do, and what the complete unit must verify:

| Function | Formed part can do | Verified on the complete unit |
|---|---|---|
| ESD protection | Static-dissipative sheet | Finished-part testing to the agreed method |
| EMI shielding | Mounting faces for conductive coatings or metal parts | System shielding test |
| RF or optical windows | Material and thickness chosen for the band or optics | Tested with the functional module |
| Cooling | Vents and air-path openings CNC-cut | Temperature rise in operation |

A cosmetic part does not replace performance testing.

## Assembly, access and interface design

A correctly sized opening isn't enough: how the plug goes in, how the cable bends and how a module slides out all count:

### Plugs and cables

Openings follow plug shape, mating direction and cable bend radius, with room for hands.

Needed: connector types and cable models

### Cooling and modules

Air-path openings and module removal paths are planned together.

Confirmed: air path and module removal path

### Functional connections

Shielding, grounding and RF windows are designed with the housing's mounting faces and seams.

Confirmed: functional parts and test requirements

## Sheet materials and project requirements

8–10 mm sheet is typical, up to 15 mm.

- **Instrument housings and bezels**: ABS is most common; PC where impact resistance is needed.
- **Anti-static**: Static-dissipative grades; color is not proof, so we verify by test method.
- **Clear windows**: PC or PETG.
- **Precision parts trays**: Thin-gauge PET, PS and similar, made in our own sheet plant.

Grade, thickness and functional treatments are evaluated per project.

## Factory, CNC trimming and inspection

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.

## Lead time from drawing to delivery

Typical timings. Complex parts or special materials get a specific schedule when we quote.

1. **Within 4 hours · Response**: An engineer contacts you to confirm use, size and quantities.
2. **2 working days · Evaluation and quote**: We tell you whether heavy-gauge fits and quote it side by side with injection molding.
3. **About 1–3 weeks · Tooling**: After design review we machine the forming tool in-house.
4. **By complexity · Samples**: Formed, trimmed and drilled, then fitted to your frame or mating parts.
5. **Per order · Production**: Checked against the approved sample for size and finish, then packed and shipped.

### FAQ

#### Can thermoforming be evaluated for electronics & advanced equipment 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 electronics & advanced equipment?

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 electronics & advanced equipment?

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 electronics & advanced equipment 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 electronics & advanced equipment?

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.
