Discussion on the advantages of rotational molding products and injection molding products by rotational molding manufacturers
Every time during the injection molding process, materials are directly added to the mold, allowing them to all enter the product and be removed from the rotational molding mold. Then, the materials required for the next molding process are added. When we need to change the color of the product, we do not waste any material or time cleaning the machine and mold. When we use multiple molds to roll and shape the same plastic product, You can also add materials of different colors to different molds and launch plastic products of different colors. So what are the advantages of rotational molding products and injection molding products? Let's get to know about it together with the rotational molding manufacturer.
Suitable for forming various complex hollow parts, during the rolling forming process, the material is gradually coated and deposited on the inner surface of the mold. The product has a strong ability to reproduce fine structures, such as patterns on the mold cavity. Due to the mold being not affected by external pressure during the forming process, casting and other methods can be directly used to produce molds with fine structure and complex shapes.
Rotational molding manufacturer
Rotational molding products save raw materials, with relatively uniform wall thickness and slightly thicker chamfers. Rotational molding box manufacturers can fully utilize material efficiency, which is beneficial for saving raw materials. During the rotational molding process, there is no waste of runners, gates, etc. After debugging, almost no furnace material is returned during the production process. Therefore, this process has a very high utilization rate of materials.
Injection molding is the process of first adding plastic to the mold, then the mold continuously rotates along two vertical axes and heats it up. The plastic inside the mold is gradually evenly coated, melted, and adhered to the entire surface of the mold cavity under the action of gravity and heat energy, forming into the desired shape and being cooled and shaped.

Compared with traditional blow molding and injection molding processes, the rotational molding process has the following advantages:
1. Cost advantage: In the rotational molding process, only the strength of the frame is required to support the material, mold, and the weight of the frame itself, in order to prevent material leakage due to the clamping force; And during the entire forming process, the material is almost unaffected by any external force except for the action of natural gravity, thus fully possessing the advantages of convenient machining and manufacturing, short cycle, and low cost.
2. Quality advantage: During the entire production process, products with rotational molding technology have more stable quality and structure due to the absence of internal stress.
3. Flexible and variable advantages: The machine mold manufacturing of the rolling molding process is convenient and cost-effective, making it particularly suitable for multi variety and small batch production in new product development.
4. Personalized design advantages: The products in the rotational molding process are easy to change colors and can be hollow (seamless without welding). The surface treatment of the products can achieve the effects of patterns, wood, stone, and metal, meeting the personalized needs of modern consumers for products.
The products produced using this process include oil tanks, water tanks, mechanical shells, mudguards, etc. The main substitutes are metal parts and fiberglass products. Injection molding is a process developed based on micro manufacturing technology such as LIGA, and of course, there are many other methods available. The LIGA process involves producing a model required for injection molding, commonly known as a "mold", and then injecting liquid plastic into the mold, separating it to form the final product required.
