Main features of rotomolding
Main features of rotomolding Advantage 1. The cost of rotomolding molds is low - for products of the same size, the cost of rotomolding molds is about 1/3 to 1/4 of the cost of blow molding and injection molds, which is suitable for large plastic products; 2. Good edge strength of rotomolded products - rotomolding can achieve a thickness of more than 5mm on the edge of the product, which completely solves the problem of thin edges of hollow products; 3. Rotomolding can place various inlays; 4. The shape of rotomolding products can be very complex, and the thickness can exceed 5mm; 5. Rotomolding can produce fully enclosed products; 6. Rotomolding products can be filled with foam materials to achieve thermal insulation; 7. There is no need to adjust the mold, and the wall thickness of the rotomolded product can be adjusted freely (above 2mm); 8. Suitable for molding large and extra large parts; 9. Rotational molding is very easy to change the color of the product - Rotational molding directly adds the material into the mold each time, so that all the material enters, and the product is taken out of the mold and then adds the material required for the next molding. When we are using multiple molds to rotomold the same plastic product, we can also add materials of different colors to different molds, and rotomolded plastic products of different colors at the same time;10. Saving raw materials - the wall thickness of rotomolding products is relatively uniform and the chamfer is slightly thicker, so it can give full play to the efficiency of the material, which is conducive to saving raw materials; in addition, in the process of rotomolding, there are no runners, gates, etc. Scrap, once debugged, is almost never returned to the furnace during the production process, so this process has a very high utilization rate of materials.
