The Source Manufacturer of Animatronic Dinosaurs in China

If you have ever stood in front of a roaring animatronic T. rex and wondered who actually built the thing, there is a good chance the answer is a workshop in Zigong. This city in southwest China has spent the last few decades turning dinosaur bones into an industry, and we are one of the factories at the middle of it.

Zigong Dino Culture & Art Co., Ltd. (that is us, and you will see us trading as YESDINO) designs, engineers and builds animatronic dinosaurs. We have been doing it since 2015, from models you could carry through a doorway to 30 m landmark pieces that need a crane and a concrete foundation. Everything is made under one roof in Zigong: steel work, mechanics, foam sculpting, skin, paint, electronics and testing.

If you are sourcing rather than browsing, here is the version in one paragraph: we are a factory, not a trading company. There is no middle layer between you and the people who weld the frame. Send us a venue, a species and a rough size, and we will tell you what it takes, what it costs and how long it takes, in writing.

Why so many animatronic dinosaurs come out of Zigong

Zigong has an unfair advantage: the dinosaurs were here first. The Zigong Dinosaur Museum, which opened in 1987, was built directly on the Dashanpu fossil site, and it holds one of the world's largest collections of Middle Jurassic dinosaur fossils. Locals call the city the Hometown of Dinosaurs for reasons that have nothing to do with marketing.

Once a place becomes famous for dinosaur bones, something predictable happens. Sculptors, mould makers, welders, foam suppliers, silicone and paint shops, motor and control-system suppliers, and freight agents all cluster around the same few square kilometres. That is what makes Zigong different from a city that simply decided to start making dinosaur models one Tuesday.

For a buyer, the cluster has three practical consequences:

• Iteration is fast. Reshaping a skull or re-proportioning a tail happens in a workshop next door, not on another continent.
• Parts stay available. Motors, linkage pins and control boards are off-the-shelf items here, which is what actually keeps a park's downtime short three years after delivery.
• You can come and look. Zigong is a few hours from Chengdu by road or rail, so factory inspection is a day trip rather than an intercontinental expedition. We would rather you visited than took our word for it.

We are aware that "Zigong factory" gets used loosely online. Two factories in the same city can be completely different operations, which is why the rest of this page is about specifics: what we build, how the mechanics work, and what you should demand in writing from any manufacturer you are comparing.

Who we are

Zigong Dino Culture & Art Co., Ltd. was founded in 2015 and has been building animatronic dinosaurs ever since, initially for domestic scenic attractions and increasingly for museums, parks and event companies abroad. We are a manufacturer: we design, we fabricate, we test, we pack and we support what we ship.

The work is split across in-house teams that hand the job to each other in a fixed order, which is why nothing gets "discovered" halfway through a build:

• Design and engineering: proportions, mechanics, load paths and CAD drawing sets for client approval.
• Steel fabrication: frame welding, joint and drive mounting, full anti-rust treatment.
• Sculpting: foam build-up, anatomy shaping and surface texture carving.
• Skin and paint: the softest part to get wrong and the hardest to hide.
• Electrics and programming: motors, wiring, control hardware, audio and trigger logic.
• Testing and packing: the ageing run, the six-point inspection and everything that keeps a 9 m dinosaur intact at sea.

We offer OEM and ODM work, which in practice means two things. If you already know what you want, we build it. If you have a venue and a budget but no firm idea yet, our team proposes species, size, motion list and scene layout, and you approve it before anyone touches a welder. Minimum order quantity is one unit, whether it is a stock design or something that has never been built before.

What we build

Our catalogue runs across more than 300 dinosaur designs, from roughly 1 m up to 30 m, and the range keeps expanding because customers keep asking for things that are not in it. Beyond the classic roster of Tyrannosaurus, Triceratops, Brachiosaurus, Velociraptor and Ankylosaurus, we build hybrid and fantasy concepts, species from specific geological periods, and animals that only exist in a client's concept sketch.

One thing worth saying out loud, because it saves buyers money: the biggest dinosaur is not automatically the best purchase. A 6 m Triceratops standing close to the path, where visitors can see the frill move, often outperforms a 15 m silhouette that people photograph once from 40 m away. If a smaller model serves your venue better, we will tell you, even though it is a smaller invoice for us.

Motors and movement: putting 13 actions into one dinosaur

On our larger builds we can fit up to 13 separate motor-driven actions, which is where that number in the specification sheet comes from. The list our clients most often ask for looks like this.

On hardware, most of our commercial builds run on low-voltage DC drive, commonly 24 V, using DC and servo motors. Hydraulics deliver more force but add a pump, a circuit, weight, cost and a standing risk of oil on your floors, so we reserve them for heavy-load special builds where the force is genuinely needed. If a quotation leans on hydraulics for an ordinary 6 m dinosaur, ask what problem the hydraulics are solving.

Trigger modes are chosen to match how your site actually operates: infrared sensor, handheld remote, coin or token start, push button, touch sensor, timer loop, or full show control synced to lighting, projection and narration. Whatever mode you pick, get three numbers in writing: sensor range and field of view, sound pressure level measured where visitors stand, and the physical location of the emergency stop.

Skin: the part that decides whether it looks alive

You can build a perfect frame and still end up with something that looks like a rental costume. The skin is where realism is won or lost, and it is the most labour-intensive stage in the entire workshop.

After years of experimentation we settled on a technique that combines elastic fabric with high-quality silicone glue. The fabric carries the load and stops the skin tearing when joints flex; the silicone provides the soft, fleshy surface that feels close to animal skin under a visitor's hand. Then the detailing starts:

• Foam first. High-elastic yellow foam goes over the moving joints, and regular high-density purple foam fills the static body sections. Using one grade everywhere is a shortcut you can feel with your hand within a year.
• Texture carving. Skin folds, scales and wrinkles are carved to roughly 3 to 5 mm deep. Carve shallow and the detail vanishes the moment paint goes on.
• Layering. Fibre-cloth reinforcement, then multiple coats of silicone, until the finished skin sits at around 4 to 5 mm total thickness.
• Paint. Base tones, muscle-shadow layers, deeper shading inside the folds, and species-specific facial detail, finished semi-matte.

That thickness window is deliberate. Too thin and the skin tears at the folds and around the joints. Too thick and the silicone fills in the carving you paid for, leaving a smooth, plastic-looking surface. If a supplier cannot tell you their target skin thickness, they are not measuring it.

Outdoor units get UV-stabilised pigments and a UV-resistant formulation, because standard paint under permanent sun fades into a washed-out version of the dinosaur you approved. Expect a touch-up repaint every two to three years outdoors; it is scheduled maintenance, not a defect.

Frame, electrics and control

The skeleton is built from Q235 carbon steel tubing, fully welded to carry the motors, the dead weight of the skin assembly and the dynamic loads of every action moving at once. Two details do most of the work in deciding how long it lasts:

• Full anti-rust coverage on every metal surface before any foam goes on. Not just the parts you can see. Once the skin is fitted, nobody inspects the inside of a dinosaur again, and hidden rust does its work in the dark.
• Heavier treatment for hard environments. Coastal and high-humidity sites get galvanised steel, or 304 stainless reinforcement at the joints and load-bearing points where corrosion starts first.

Electrically, we build for the destination: 110 V or 220 V AC at 50 or 60 Hz, with regional plug standards, and typical consumption of 200 to 800 W per unit depending on size and effect package. Battery-powered configurations are possible for event use where running a cable is not practical.

How a custom order runs: CAD drawings first

Custom work is most of what we do, so it is worth being precise about how it starts. Nothing gets welded until you have approved the drawings.

1. Brief and site information. You send the venue, the species or concept, rough size, movement wish list, indoor or outdoor, destination country and deadline. Site measurements matter: ceiling height, door and gate widths, the access path to the final position, and floor load.
2. CAD drawing package. Our engineering team issues a complete drawing set within three to five working days: frame and weldment layout, joint positions, drive placement, base-plate dimensions and control layout. This is the document you sign. It is also the document that fixes your price.
3. Written approval. You approve the drawings, or ask for changes, which are free at this stage and expensive after steel is cut.
4. Bench validation of critical joints. On large builds, head, neck and tail sub-assemblies are tested on jigs before permanent welding, so linkage ratios and pivot positions can be corrected while everything is still bolted to a rig.
5. Production. Frame welding, anti-rust treatment, electrics, foam sculpting, skin, paint, then programming. Each stage gets an internal sign-off before the next one starts.
6. Testing and packing. A minimum 24-hour continuous ageing run, the six-point inspection below, and then container-grade packing with a per-segment packing list.

Stock models skip steps 1 to 4, because the engineering already exists. Ordering one is genuinely fast, and if the design is right for your venue there is no reason to customise anything except the paint.

What gets checked before anything ships

Factory testing is not a formality, and it is the cheapest insurance in the whole project. Before a unit is allowed anywhere near a packing crate, it passes six inspection areas:

1. Frame and welds: structural strength, joint alignment and mechanical stability.
2. Electrical systems: full load testing of motors, wiring and internal components.
3. Sculpt: proportions, muscle form and overall realism against the approved drawings.
4. Skin surface: detail sharpness, and no defects in the skin itself.
5. Skin adhesion: consistent bonding to the foam substrate, especially around moving joints.
6. Paint and detail parts: finish quality plus eyes, teeth, claws and every small component.

Running alongside that is the ageing test: a minimum of 24 hours of continuous operation, cycling through the full movement list the way your park would use it on a busy day. Motors get hot, wiring reveals its weak points, and linkages show you what they are made of. You receive video and photo records of the run rather than a two-minute highlight clip, and you are welcome to ask for the raw footage.

On paperwork: our electrical components are CE-marked where applicable, we work to ISO 9001 quality-management processes, and independent third-party inspection (BV, TUV or SGS) can be arranged on request at additional cost. Ask for certificate numbers and the inspection scope; a logo on a brochure page is not a certificate.

Shipping, container splitting and installation

Large animatronic dinosaurs travel in pieces, and the rules of thumb are worth knowing early because they affect your access plan and your base design:

• Units taller than about 2.6 m or wider than about 2 m are built as separable sections to fit a standard sea container.
• Anything longer than roughly 8 m almost always ships in several segments regardless of other dimensions.
• Fragile components such as eyes, mouth parts, claws and skin edges are individually wrapped in foam and bubble film.
• Full-container-load shipments travel secured inside the container; less-than-container-load shipments go into air cases or heavy wooden crates.

You should receive a packing list documenting every segment's dimensions and weight. That is not admin: you need those numbers to confirm your site can accept the largest piece, and to arrange lifting equipment before the truck arrives rather than after.

While your dinosaur is still in production, finish the site work. Foundation and anchor layout matching the delivered base plate, power cable routes, drainage, and a shelter over wherever the control boxes will live. Doing this in parallel with factory production is the single biggest schedule win available to you.

Installation support comes in three levels: a printed installation and maintenance manual plus step-by-step assembly videos as standard, remote video guidance through commissioning as standard, and an engineer dispatched to your site for large or complex projects, quoted separately.

Warranty, spares and after-sales support

Our standard warranty on a delivered unit runs 12 to 24 months depending on the build and specification, with paid extension available up to 60 months. Read the exclusions on any warranty, ours included: wear items such as silicone skin and linkage pins are normally outside base cover, which is fair as long as you know it before you order rather than after.

Every unit ships with a dedicated spare-parts kit, and we keep parts available long after delivery. The practical promise is simpler than the legal one: when a motor or a board fails in year four, you should be able to get the part, not a lecture about how the model is discontinued. Remote video troubleshooting is standard practice and resolves most issues without anyone getting on a plane. On-site engineer dispatch is quoted separately and usually makes sense only for large installations.

What keeps an exhibit alive is unglamorous and consistent:

Frequently asked questions

The short version, if you are still deciding

• We are a factory, not a trading company. Steel, foam, skin, paint, electrics and testing all happen in our own workshop in Zigong.
• One unit is a valid order. 300+ designs from 1 m to 30 m, stock or fully custom.
• Up to 13 movements, chosen because they will read on site, not because a bigger number looks better in a quotation.
• You approve drawings, not a wish list. A full CAD drawing package within three to five working days, then bench testing, then production.
• Nothing ships without a 24-hour ageing run and a six-point inspection.

Tell us the venue, the species and the deadline, and we will come back with drawings, a movement list, a price and a production schedule. If a smaller model suits your site better than the one you asked about, we will say so, and we would rather lose the bigger sale than watch a dinosaur fail in front of your visitors.
