With the development of the rotary molding process, the application scope of the products has been expanded. The application of rotating molding products has been widely applied. Some typical applications can be cited as follows.
1. The container classes rotational molding parts, such as plastic parts are widely used in reservoir, all kinds of liquid chemical storage tank (such as acid, alkali, salt, chemical fertilizer, pesticide, etc.), the gasoline used containers (gasoline storage tank and tank cars, planes use), battery shell, and so on.
2. The automobile is made of rotary molding, mainly applied polyethylene and polyvinyl chloride paste resin, rolling out various pipe fittings, such as air conditioner bend, backrest, handrail, etc.
3. Sports equipment and various substitutes.There are various kinds of products, such as water polo, float ball, bicycle cushion, small boat, and cushion shock absorber between the ship and dock.The roll-plastic cross-linking polyethylene bucket made from the roller of the company's roll-plastic grade crosslinked polyethylene tree can compete with the metal drum, and it is resistant to chemical corrosion and low maintenance costs.Roll-plastic stacking disk, in the early 1970s, in the United States, Japan and other countries have been commercialized;Surfboards, boats, etc. Are also commonly referred to in the literature for rolling.
4. Toys, models, crafts, etc.Because the rotary molding tool can be made by precision casting, electroforming, etc.Roll with molding pieces of fine structure on the surface of the mold cavity surface "copy" effect is very good, so the rotomolding method can make the products be quite delicate and beautiful, reason often used in making is: great ornamental value of the products, particularly toys, models, crafts, etc.
In addition to the above, along with a variety of rotational molding products is widely applied case, shell, large pipes and other parts, such as turnover box, dustbin, machine shell, shield, chimney, bathroom, toilet and telephone, yacht, etc.Rotational molding products in liquid chemicals, suitable chemical enterprises, industrial coating, re wash tank, reaction tank, etc., in the making and hohai life buoy, water tanks, and other fields has been widely used.
