Product Details
What is rotational molding?
Rotational molding is a method of hollow forming using thermoplastic materials, suitable for most large and medium-sized plastic products and composite products, with good product quality and low investment costs.
The basic process includes the following steps:
1. Pour a certain amount of powder raw material into the mold and combine the mold using screws or clamps.
2. Heat the mold and rotate it at 360 degrees in an oven; the raw material melts within 230-300 degrees Celsius in the mold, evenly adhering to the inner surface of the mold to form the desired shape; the heating time depends on the material, shape, type, and weight of the mold.
3. After reaching a certain time and completing the heating, the arm moves to the cooling station to start cooling, usually using air cooling and water mist cooling. When the surface of the mold cools to between 80-90 degrees Celsius, the rotation of the arm stops, the mold is opened, and the product completes the molding process.
Advantages of rotational molding
1. Low cost of rotational molding molds: For products of the same specification, the cost of rotational molding molds is about 1/3 to 1/4 of that of blow molding and injection molding molds.
2. Good edge strength of rotational molding products; rotational molding can achieve a thickness of more than 5 millimeters at the edges of products, completely solving the problem of thin edges in hollow products.
3. Rotational molding can accommodate various accessories.
4. The shape of rotational molding products can be very complex, with a thickness of more than 5 millimeters.
5. Rotational molding can produce fully sealed products.
6. Rotational molding products can be filled with foam materials for insulation.
7. No need to adjust the mold; the wall thickness of rotational molding products can be freely adjusted (over 2mm).
8. The products are hollow and seamless, but the wall thickness can be adjusted to give the products high strength.
9. Various surface pattern treatments can be provided, producing products in various colors, and can be treated for UV resistance and aging.
10. Rotational molding is suitable for large hollow plastic products (for example, water towers, steel-lined plastics, etc.)
