Rotational molding is not only one of the primary manufacturing methods for medium and large-sized hollow plastic products, but it is also the main processing method for super-large and irregularly shaped hollow plastic products. Furthermore, with the continuous development of rotational molding technology, it is now possible to produce solid foam plastic products through the rotational foam molding process.
In daily life, the variety of plastic products that can be produced through rotational molding is extensive and ubiquitous. From small items like ear scoops, ping pong balls, and dolls, to medium-sized products like traffic barriers, coolers, mannequins, and landscaping planters, to large items such as slides, automobile exteriors, boats, water tanks, and storage silos, rotational molding enables the manufacture of a diverse range of plastic products.

Rotational Molding Materials Requirements for Common Products
Rotational molding products come in a wide variety of types, and the specific requirements for the raw materials can vary depending on the intended application, usage, location, indoor/outdoor environment, and other factors. Here are the key material requirements for some common rotational molded products:
Rotational molding products come in a wide variety of types, and the specific requirements for the raw materials can vary depending on the intended application, usage, location, indoor/outdoor environment, and other factors. Here are the key material requirements for some common rotational molded products:
➤ Containers: Require good environmental stress crack resistance (ESCR), UV resistance, chemical resistance, high rigidity and creep resistance, and moderate melt flow rate.
➤ Manholes: Require high strength, impact resistance, toughness, and ESCR, as well as good rigidity.
➤ Toys: Require UV resistance, color fastness, slightly higher melt flow rate for good flowability and moldability, high impact resistance, good colorability, and non-toxicity.
➤ Fuel Tanks: Require high barrier properties, ESCR, strength, high melt flow rate for good processability, thermal resistance, and chemical resistance.
➤ Furniture: Require high strength, good colorability, high abrasion resistance and hardness, and low shrinkage.
➤ Pallets: Require high impact resistance, rigidity, high melt flow rate, good creep resistance.
➤ Boats: Require high impact resistance, UV resistance, high strength, good flowability, toughness, and ESCR.
