The application of rotomolding

Feb 01, 2018

With the development of the rotary molding process, the range of its products has been expanding. The application of rotary molded products has been very wide. Some representative applications are as follows.

1. Containers Rotary molding parts, such plastic parts are widely used in water storage tanks, storage tanks of various liquid chemicals (such as acid, alkali, salt, chemical fertilizers, pesticides, etc.), petrol containers And cars, aircraft fuel tank), battery case and so on.

2. Automotive rotary molding parts, mainly the application of polyethylene and PVC paste resin, rotational molding a variety of pipe fittings, such as air conditioning elbow, backrest, handrails and so on.

3. Sports equipment and a variety of substitutes. There are a variety of PVC plastic parts, such as water polo, floats, bicycle saddles, boats and boats and docks between the buffer shock absorber. The rotomolded cross-linked polyethylene (PET) drums from the company's rotomolding-grade cross-linked polyethylene "Maricxcl-100" can compete with metal drums and offer good chemical resistance and low maintenance costs. The rotomolding pallets were commercialized in the United States, Japan and other countries in the early 1970s. Surfboards, boats and the like are also commonly referred to in the literature as rotational molding.

4. Toys, models, handicrafts and so on. As the rotating mold can be molded by precision casting, electroforming and other manufacturing processes; rotomoulding the surface of the mold cavity fine structure of the surface structure "replication" is very good, so the rotational molding method can make the product is quite exquisite appearance, it is often used In the production of more: the value of large ornamental products, especially toys, models, handicrafts and so on.

In addition to the above, there are a variety of rotating molded products are widely used in various boxes, housings, large pipes and other parts, such as turnover boxes, bins, machine enclosures, enclosures, lampshades, bathrooms, toilets and telephone rooms, yachts and many more. Rotary molding products in the liquid chemicals storage and transportation, chemical companies, industrial coatings, rare earth preparation in the tank, the reaction tank, as well as the Hohai buoy, living water tanks and other fields have been widely used.
