Football toys are typically produced using what method?

Football toys are typically produced using blow moulding. This method is particularly suited for creating hollow plastic objects, allowing for the production of lightweight and durable items such as toys. In blow moulding, a tube of heated plastic, known as a parison, is inflated within a mould to form a hollow shape. This process is ideal for items like footballs, where a spherical shape with an internal cavity is necessary.

Rotational casting is generally used for larger and more complex shapes and would not yield the same efficient results as blow moulding for toy production. Transfer moulding and injection moulding are more commonly associated with solid items or parts with intricate details rather than hollow forms. Therefore, while rotational casting might find its niche in certain applications, it is not the preferred choice for the production of football toys.
