What material is the electric dinosaur model made of?

In some large scenic spots and parks, we can often see the figures of simulated dinosaur models, or show their teeth and claws, or be naive, and can also make vivid movements and make terrifying sounds. Presumably many tourists will be curious, what material is the simulated dinosaur model made of?

The common material is sponge silicone, which is characterized by softness and elasticity. And the touch is very real, like touching a real creature. A motor and a transmission structure are installed inside to create a dinosaur model with action functions.

When making, first use steel such as channel steel round pipe and square pipe, and cut the dinosaur-shaped steel skeleton according to the design drawings. Then weld according to the action of the simulated dinosaur model. The moving parts are welded into movable joints, and the non-moving parts are directly welded into a fixed structure.

Next, install the motor and transmission structure on the dinosaur. For the motor, you can use a DC brush motor or a stepper motor, and there is also a pneumatic simulation dinosaur that can only use a cylinder. Coolie models can be made with either motors or cylinders, but cylinders are relatively more expensive.

Finally, the sponge is used as the base. The artist makes a corresponding rough model of the dinosaur model according to the type and shape of the dinosaur. After adding the skin fiber, the waterproof and sealing process can be used for coloring. The coloring is generally done with oily acrylic paint, which can Prevent fading after rain.

After the production is completed, the motion program is written, and a simulated dinosaur model is completed. Of course, there is also a dinosaur model made of glass fiber reinforced plastic, but the surface of the material is hard and cannot be equipped with a motor to create dynamic effects. And it is easy to fade and crack when placed outdoors for a long time.
