How action figures are made

Raw Materials
Aluminum wire, modeling clay, and various sculpting tools are used to create the prototype. The actual figure is molded from a plastic resin, such as acrylonitrile butadiene styrene (ABS). This is a harder plastic used to form the main body. Softer plastics, like polypropylene and polyethylene, are commonly used to mold smaller accessory and costume pieces. Various fabrics, such as rayon and nylon, may be used for costume components including body suits, capes, and face masks. As a final decoration, acrylic paints of various colors may be used to decorate the figure. In addition, more elaborate toys may contain miniature electronic components that provide light and sound effects.

Design
Once the character has been selected, the actual design process begins with sketches of the proposed figure. The next step is the creation of a clay prototype. This model is made by bending aluminum wires to form the backbone of the figure, known as an armature. The wire form includes the outline of the arms and legs posed in the general stance that the figure will assume. The sculptor then adds clay to the armature to give the basic weight and shape that is desired. The clay may be baked slightly during the prototyping process to harden it. Then, the sculptor uses various tools, such as a wire loop, to carve the clay and shape details on the figure.

After creating the basic form, the sculptor may choose to remove the arms and work on them separately for later attachment. This gives the sculptor more control and allows him to produce finer details on the proto-type. Working with blunt tools, the sculptor shapes the body with as much detail as is desired. During this process, photo and sketch references are used to ensure the figure is as realistic as possible. Some sculptors may even use human models to guide their design work.

After the general body shape is complete, the sculptor adds the finer details, paying close attention to the eyes, nose, and mouth that give the figure its life-like expression. The designer may attach a rough lump of clay on the main figure as a temporary head while the real head is sculpted on a separate armature. This allows the sculptor to finish the figure's facial expressions independently of the body. At this point, the finished head can be attached to the main armature and joined to the body with additional clay. Once the head is attached, the neck and hair are sculpted to properly fit to the figure. Then, depending on the design of the figure, the costume may be sculpted directly onto the body. However, if a cloth costume or uniform will be added later, the prototype is sculpted without any costume details. During this process, parts of the clay may be covered with aluminum foil to keep it from prematurely drying out. Once everything is completed, the entire figure is baked to harden the clay.

The sculpted prototype is then sent for approval to the manufacturer. Once all design details have been finalized, the prototype is used to make the molds that will form the plastic pieces for the mass-produced figure. The entire sculpting process may take about two weeks, depending on the skill and speed of the sculptor. This process may be repeated several times if revisions must be made to the figure. Several months are typically allowed for this design phase.
