When examining toy crane machines commonly found in arcades and entertainment centers, the construction typically involves a combination of both plastic and metal materials. The external cabinet and decorative elements are predominantly made from durable plastics or sometimes medium-density fiberboard with plastic laminates. These plastic components provide the colorful exterior and help reduce overall weight while maintaining structural integrity.

The internal working mechanisms, however, largely consist of metal components. The crane arm itself, the claw mechanism, support beams, and crucial moving parts are typically constructed from steel or aluminum alloys to ensure strength and durability. The metal framework provides the necessary stability for the machine to operate consistently despite frequent use.

Electrical components including wiring, motors, and sensors are housed within metal protective casings. The prize drop chute and coin mechanism also feature metal construction to withstand repeated use. Modern manufacturers often use powder-coated steel for corrosion resistance in the metal parts, while high-impact ABS plastic covers the exterior.

The specific material ratio varies between manufacturers and machine models. Commercial-grade machines intended for heavy arcade use tend to incorporate more metal components, particularly in stress-bearing areas. Smaller consumer versions for home use may feature more plastic construction to reduce costs and weight. Understanding this material combination helps explain why these machines can withstand years of operation while maintaining their visual appeal.
