--- title: "Heavy-Gauge Thermoformed Housings & Enclosures | FUNYO" description: "Thermoformed housings and enclosures up to 2600 × 1600 × 600 mm. Tooling takes 1–3 weeks; FUNYO forms and CNC-trims parts in Zhuhai." type: landing --- # Thermoformed Housings & Enclosures A 2.6-meter housing. No injection mold first. Thermoformed Housings & Enclosures 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. ![Illustration of a heavy-gauge equipment housing](/assets/heavy-gauge/housing.webp) Illustration: equipment housing formed in one piece, openings and vents CNC-cut - **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 ## Sizes and forms of heavy-gauge thermoformed housings Three common forms, one route: tool, form, CNC trim. ### Equipment housings Upper/lower shells · bezels · side panels Exterior parts for medical devices, instruments and robots. Curves and generous radii form in one shot; display windows, button holes and vents are CNC-cut to your drawing. ### Enclosures & lids Deep box + lid · main shell + rear cover Control boxes, energy-storage and power-module enclosures, test units. Mounting holes, cable entries and sealing faces are machined to drawing; brackets and threaded inserts fit as separate parts. ### Large body parts One piece or split Up to 2.6 m long and 600 mm deep in one piece, so one seam fewer. Larger parts are formed in sections and joined. Used for autonomous-equipment bodies, leisure equipment and construction-machine covers. Maximum size is the forming envelope for one part. Draft, radii and trim allowance come off that; we confirm the finished size at evaluation. ### Examples ![Medical equipment housing](/assets/cases/medical-housing.webp) Medical equipment housing ![Large medical equipment housing](/assets/cases/large-medical-housing.webp) Large medical equipment housing ![Power battery housing](/assets/ppt/power-battery-housing.webp) Power battery housing ![Illustration · EV charger housing](/assets/illustrations/charger.webp) EV charger housing (Illustration) ![AI and service robots](/assets/ppt/service-robot.webp) AI and service robots ![Drone shell](/assets/ppt/drone-shell.webp) Drone shell Photos are from FUNYO’s company profile; the caption identifies the thermoformed part.

Select a style to see where it fits. ### Deep box + separate lid Loaded from the top Components drop in from above; the lid comes off on its own. Common for control boxes and energy-storage or power modules. ### Upper and lower shells Closes around the components Two shells close around the internals; the parting line and datums are fixed before tooling. Common for instruments, medical devices and robot bodies. ### Main shell + rear access cover Serviced from the back The front stays clean; a rear cover handles installation and service. Common for equipment that is opened often. Hinges, brackets and threaded inserts fit as separate parts. For waterproof or flame-retardant enclosures, tell us the target rating and we evaluate material and design together. ## Sheet materials for thermoformed housings Housings typically use 8–10 mm sheet, up to 15 mm. Every sheet below runs on our heavy-gauge formers; weatherable or flame-retardant grades are sourced per project. | Sheet | Typical use | |---|---| | ABS | The most common housing material: stiff and easy to machine. FUNYO runs its own ABS sheet plant, so color and cost are easier to control. | | PC | When you need more toughness and impact resistance, or a clear window. | | PVC | Chemical resistance, and parts with flame-retardance requirements. | | PETG | Clear or translucent cosmetic parts and display housings. | | PP / PE | Chemical and impact resistance for boxes and handling parts, at low weight. | Exact grade, color and texture are approved on physical swatches and samples. ## Related product families - [Thermoformed Machine Covers & Shrouds](/en/products/covers-shrouds) - [Thermoformed Panels & Fascias](/en/products/panels-fascias) - [Thermoformed Handling Trays & Liners](/en/products/trays-liners) - [Thermoformed POP Displays and Light Box Faces](/en/products/displays-signage) - [Quality assurance](/en/quality/quality-assurance) - [Tooling & process engineering](/en/quality/tooling-process-engineering) - [Technical cleanliness](/en/quality/technical-cleanliness) ## 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. ![FUNYO heavy-gauge thermoforming machine](/assets/factory/heavy-forming.webp) Heavy-gauge former: ABS, PC, PVC, PETG and PP sheet; parts up to 2600 × 1600 × 600 mm ![FUNYO 3-axis and 5-axis CNC routers with a formed part on the bed](/assets/factory/cnc-router.webp) 3- and 5-axis CNC routers: trimming, holes and slots after forming; 5-axis for curved surfaces ![Tunnel oven in FUNYO's secondary-processing area](/assets/factory/tunnel-oven.webp) Tunnel oven for secondary processing: adjustable temperature, airflow and conveyor speed ![Engineer measuring a part on a vision measuring system](/assets/thin-gauge/cmm.webp) Vision measuring system checks holes and contours; a 3D automatic vision system is also on site ### Facts you can check - **2004**: Founded; 20+ years of precision machining - **2005**: Became a tier-1 supplier to Gree - **ISO 9001 · 14001**: Quality and environmental management certified - **2024**: Recognized as a High-Tech Enterprise - **ABS · PET/PS**: Own plant for thermoforming sheet - **4 hours**: Response to design requests ### Selected long-term customers Gree Electric, Panasonic, Foxconn, Jabil, Lite-On, TDK, Mitsumi Electric, Mektec, Broad-Ocean Motor, Haojue, JCD, AKM, CYGIA These relationships cover precision formed trays, CNC parts and other work.

Compare part size, assembly, material, tooling and unit costs before selecting a process. #### What size and sheet thickness can a thermoformed housing reach? 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. #### How does thermoforming tooling cost compare with injection molds, and how many weeks does it 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. #### Does moving CNC-cut openings for a new model require another forming tool? If the external geometry, sheet and forming datums stay unchanged, we can evaluate a CNC program and fixture change. Changes to the formed shape require a separate tooling review. #### Can medical or industrial housings meet a UL 94 or IP rating? Provide the target rating first. Material grades are sourced and sampled per project; the housing, seals and assembly must be assessed together. Final ratings depend on testing the complete equipment. #### Which sheet materials are available for housings and transparent windows? 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. #### Can I receive a response in 4 hours, and when will thermoformed samples be ready? We respond in 4 hours and provide an applicability assessment and injection-molding comparison quote in 2 working days. Forming tooling takes about 1–3 weeks; sample timing is assessed against the part geometry. #### Can a housing project of about 3,000 parts per year apply for no tooling charge? Housing projects of about 3,000 parts a year under an annual supply agreement can apply for an assessment. The quotation and contract define charges, amortization and tool ownership; eligibility is not automatic. ## Contact Bring us your next big idea. Let’s give it the right shape.
