What is Hollow One-piece Plastic Products Created by Rotational Molding?

Rotational molding is mainly used to produce hollow one-piece plastic products. This process is capable of producing a wide range of parts, from small to extreme large, from the simple to very complex shapes. So, what kind of plastic products are hollow plastic products molded by rotational molding process?

Hollow rotomolded plastic products are seamless, uniform in wall thickness and of single construction. The parts can be fully or partially closed items. If the part has an opening, this opening is much smaller than its internal space. It has two features with an inner surface, that is to say, it must be hollow in the middle; the opening connected to the interior of the product must be a small part of the surface of the product. This definition is more professional and abstract. Generally speaking, hollow plastic products refer to products with a small opening or even no opening, and the rest are all surrounded by plastic to form a hollow product. Rotomolded plastic products are commonly seen during our day-to-day activities. The plastic products such as bottles, pots, boxes, cans, barrels, balls, boxes, etc., are basically hollow plastic products regardless of size or complexity. Though some rotomolded plastic products visually look like solid plastic product, actually they are hollow products, such as the rotomolded door, rotomolded furniture. Not all the rotomolded plastic products are hollow, such as the large-scale covers, enclosures and housings.
