Application of rotational molding technology

Application of rotational molding technology

Currently, rotomolded products are used in transportation, traffic safety equipment, entertainment, river dredging, construction, water treatment, pharmaceuticals and food, electronics, chemicals, aquaculture, textile printing and dyeing, and other industries.

1. Container-type rotationally molded parts. These plastic parts are widely used in water tanks, storage tanks for various liquid chemicals (such as acids, alkalis, salts, chemical fertilizers, pesticides, etc.), gasoline containers (gasoline storage tanks and fuel tanks for automobiles and aircraft), battery casings, and so on.

2. Automotive rotationally molded parts. Polyethylene and polyvinyl chloride resins are primarily used for rotomolding various pipes and fittings, such as air conditioning elbows, backrests, and armrests.

3. Sports equipment and various substitutes. These primarily include various rotomolded polyvinyl chloride parts, such as water balls, floats, bicycle seats, boats, and shock absorbers between boats and docks. Surfboards and boats are also rotomolded parts.

4. Toys, mannequins, and handicrafts. Because rotational molding molds can be manufactured using processes such as precision casting and electroforming, and the surface of the rotomolded part closely replicates the fine structure of the mold cavity, rotomolding can produce highly refined and aesthetically pleasing products. It is therefore often used to create products with high ornamental value, particularly toys, mannequins, and handicrafts.

In addition to the aforementioned applications, rotationally molded products are also widely used in various boxes, housings, and large pipes, such as turnover boxes, trash cans, machine casings, protective covers, lampshades, bathrooms, toilets, telephone booths, and yachts. Rotomolded products have found widespread use in the storage and transportation of liquid chemicals, in chemical plants, industrial coatings, in washing tanks and reaction vessels used in rare earth production, as well as in river and sea buoys and domestic water tanks.
