In some industries, the demand for products is subject to seasonal fluctuations, and this has a profound impact on the industrial mould production plan. For example, in the toy industry, which is highly seasonal. Toy sales peak during the holiday seasons such as Christmas and New Year. Manufacturers need to produce a large quantity of toys in the months leading up to these holidays. This means that the industrial moulds used to produce toy parts must be ready well in advance. The industrial moulds for making different toy components, like the plastic bodies of action figures or the wheels of toy cars, need to be in ideal working condition during this high - demand period.
