The characteristics and application of rotomolding process

Number of visits: Date:2017-08-01
  Rotational molding technology:
 
  Rotational molding, also known as rotary molding (Rotational Molding), it is the amount of powdery resin into the cold mold, driven by the plastic molding machine around two mutually perpendicular to the axis of the slow rotation and rotation, while Heating the mold with an external heating source so that the resin powder is melted and uniformly coated on the entire cavity surface of the mold by means of its own gravity, and finally the hollow product is obtained by cooling and demoulding.
 
  Molding process features:
 
  1, rotomolding mold low cost: the same size of the product, the cost of rotomolding mold is about blow molding, injection mold costs 1/3 to 1 /
 
  2, rotten plastic products edge strength is good, rotomolding can achieve the edge of the product thickness of more than 5 mm, completely solve the problem of thin edge of hollow products;
 
  3, rotomolding can be placed all kinds of inserts;
 
  4, the shape of rotomolding products can be very complex, and the thickness of more than 5 mm;
 
  5, rotomolding can produce fully enclosed products;
 
  6, rotomolding products can be filled with foam material, to achieve insulation;
 
  7, no need to adjust the mold, rotomolding product wall thickness can be freely adjusted (2mm above);
 
  8, the product seamless hollow, but you can adjust the wall thickness, so that products with high strength;
 
  9, can provide a variety of surface pattern processing, the production of various color products, can be used for anti-UV anti-aging treatment, for a variety of stone, wood simulation results.
 
  The main application of rotomolding products
 
  With the continuous development of rotomoulding process, the type of rotomolding products continue to increase, the scope of application has also been expanding. At present, domestic and foreign rotomoulding products involved in the industry, including transport, traffic safety facilities, entertainment, river dredging, construction, water treatment, pharmaceutical food, electronics, chemicals, aquaculture, textile printing and dyeing, etc.:
 
  1, the container type rotomoulding parts
 
  This kind of plastic parts are widely used in storage and supply boxes, storage tanks, various industrial chemicals storage and transportation containers such as acid, alkali, salt, chemical fertilizers, pesticide storage tanks, chemical enterprises, industrial coatings, rare earth Preparation of the tank, reaction tank, turnover me, trash, septic tanks, living water tanks and so on. The rotomeric cross-linked polyethylene barrels made with Ferrophle-based XLPE resin "Maricxcl-100" can be comparable to metal buckets and are resistant to chemical corrosion and low maintenance The
 
  2, the use of rotomoulding vehicle parts
 
  Mainly used in the application of polyethylene and PVC paste resin, rotten various automotive parts, such as air conditioning elbow, vortex tube, backrest, armrest, fuel tank, fender, door frame and shift lever cover, battery shell, snow car And motorized fuel tanks, aircraft tanks, yachts and their water tanks, boats and boats and dock between the buffer absorber and so on.
 
  3, sports equipment, toys, handicrafts rotomoulding pieces
 
There are various types of plastic, such as water polo, float, small swimming pool, recreational boat and its water tank, bicycle cushions, rotomolding pallet, surfboard and so on. As the rotomoulding mold can be used precision casting, electroforming and other manufacturing process; rotomoulding surface of the mold cavity surface fine structure "copy" effect is very good, so the rotomorphic method can be done very delicate products, so commonly used In the preparation of products with greater ornamental value, especially toys such as ponies, dolls, toy boxes, fashion model models, handicrafts and so on.
 
  4, all kinds of large or non-standard category rotomoulding pieces
 
  Rotary molding products are also used in a variety of box, shell, large pipe and other parts, such as shelves, machine shell, protective cover, lampshade, agricultural sprayer, furniture, canoe, camping vehicle roof, Equipment, planter, bathroom, toilet, telephone, advertising display card, chair, highway isolation pier, traffic cone, river buoy, crash barrel and construction barrier and so on.
 
  I long-term domestic and foreign customers for all kinds of custom-made rotomoulding molds and rotomolding products, according to the drawings or samples provided by customers and design design mold, customers can process all kinds of rotomolding products.
