With the continuous development of rotational molding technology, the types of rotational molding products are constantly increasing, and the application scope is also expanding. At present, the industries involved in rotational molding products at home and abroad include transportation vehicles, traffic safety facilities, entertainment industry, river and waterway dredging, construction industry, water treatment, medicine and food, electronics, chemical industry, aquaculture, textile printing and dyeing, etc

  1. Container type rotational molding parts
 
  These types of plastic parts are widely used for storage and feeding boxes, water storage tanks, storage and transportation containers for various industrial chemicals, such as acid, alkali, salt, chemical fertilizer, pesticide storage tanks, washing tanks, reaction tanks, turnover boxes, garbage bins, septic tanks, domestic water tanks, etc. in chemical enterprises, industrial painting, rare earth production, and so on. If the roll molded cross-linked polyethylene barrel made of Maricxcl-100, a roll molded cross-linked polyethylene resin from Philips, is used, it can be comparable to metal barrels, and it has good chemical corrosion resistance and low maintenance costs.
 
  2. Rolling plastic parts for transportation vehicles
 
  The main application is the use of polyethylene and polyvinyl chloride paste resin to roll mold various automotive parts, such as air conditioning bends, vortex tubes, backrests, armrests, fuel tanks, mudguards, door frames and gear lever covers, battery housings, fuel tanks for snow cars and motorcycles, aircraft fuel tanks, yachts and their water tanks, small boats, and shock absorbers between boats and docks.
 
  3. Sports equipment, toys, handicrafts and other rotational molded parts
 
  There are mainly various components made of PVC paste and roll molding, such as water balloons, floating balls, small swimming pools, recreational boats and their water tanks, bicycle seat cushions, roll molding pallets, surfboards, and so on. Due to the fact that rotational molding molds can be manufactured using precision casting, electroplating, and other processes; The surface of the rotational molding part has a good "replication" effect on the fine structure of the mold cavity surface, so the rotational molding method can make the product quite exquisite and beautiful. Therefore, it is often used to produce products with great ornamental value, especially toys such as ponies, dolls, toy sandboxes, fashion models, handicrafts, etc.
 
  4. Various large or non-standard rotational molded parts
 
  There are also various boxes, shells, large pipes and other products that are widely used for rotational molding products, such as shelving, machine shells, protective covers, lampshades, agricultural spray, furniture, canoes, camping vehicle roofs, playground devices, planters, bathrooms, toilets, telephone rooms, bulletin boards, chairs, highway isolation piers, traffic cones, river and sea buoys, anti-collision cylinders, and construction barriers.
 
  Roll molding is an economical and effective method for producing large hollow plastic products. To promote the application of roll molding in China, it is necessary to absorb advanced foreign technology, develop more and better roll molding materials, improve the automation level of roll molding equipment, and shorten the mold design and manufacturing cycle. I believe that with the continuous progress of modern materials industry, mechanical manufacturing and automation technology, the rotational molding process will have rapid development in China.
