Twist cars are primarily made of engineering polypropylene through injection molding.
Engineering polypropylene: This is a thermoplastic resin obtained by polymerizing propylene. Depending on the arrangement of methyl groups, engineering polypropylene can be divided into isotactic polypropylene, atactic polypropylene, and syndiotactic polypropylene. This material has good mechanical properties, chemical stability, and processing performance, making it very suitable for manufacturing toy cars like twist cars that need to withstand a certain amount of pressure and wear.
Injection molding: Injection molding is an industrial product manufacturing method, particularly suitable for molding materials such as plastics and rubber. In the manufacturing process of twist cars, engineering polypropylene granules are heated and melted, then injected into a mold. After cooling and solidification, the various parts of the twist car are obtained. Injection molding has advantages such as high production efficiency, low cost, and strong reproducibility, enabling the large-scale production and widespread use of twist cars.
Twist cars, also known as rocking cars, are loved by children and parents alike for their unique design and gameplay. They are not only affordable and suitable for parent-child activities, but can also be played solo or in groups, helping to cultivate children's learning abilities and teamwork spirit. Because of their low ground clearance, scooters offer a significant advantage in ensuring children's safety.
