Comparison of Rotational Molding Products and Other Molding Process

Products Question:

What are the differences in performance and application between rotational molding products and injection molding products?

Answer:

There are many differences between rotational molding products and injection molding products. In terms of performance, rotational molding products have uniform wall thickness, no corner waste or weld seams, evenly distributed internal stress, are not easy to deform, have good strength and sealing properties, can produce complex shapes, and can be filled with foam materials to achieve insulation and other functions. On the other hand, injection molding products have high dimensional accuracy, high production efficiency, but high mold costs, and have certain limitations in producing complex shapes and large products. In terms of application, rotational molding products are commonly used in the container field, such as water tanks, chemical storage tanks, etc.; in the automotive field, such as pipes and interior parts; and in sports equipment, such as water balls and small boats. Injection molding products are widely used in electronic and electrical enclosures, precision parts, and daily necessities, all of which require high dimensional accuracy and appearance standards.

Advantages of Rotational Molding Products in Practical 

Applications Question:

What are the advantages of garbage bins produced by rotational molding technology?

Answer:

Garbage bins produced by rotational molding technology have many advantages. First, the mold cost for rotational molding is low, which can effectively reduce costs for garbage bins that are in high demand but do not require extremely high precision. Second, rotational molding can produce garbage bins with uniform wall thickness, which improves edge strength, making them more durable and less prone to damage. Additionally, rotationally molded garbage bins can have a fully sealed structure, which effectively prevents the spread of unpleasant odors and the entry of rainwater. Furthermore, their shapes can be designed to be very complex, and they come in various colors, making them both aesthetically pleasing and able to meet different usage scenarios, such as in outdoor parks and streets where they exhibit good weather resistance and UV resistance, allowing them to be used for a long time without fading or aging.

Development trends and market prospects of rotational molding products

Products Question:

What are the development trends of rotational molding products in the coming years?

Answer:

Rotational molding products have a broad development prospect in the coming years. On one hand, with continuous technological advancements, automated production lines and intelligent control systems will gradually be applied to the rotational molding process, which will improve production efficiency and the stability of product quality, while reducing production costs and labor intensity. On the other hand, in the context of increasingly stringent environmental requirements, bio-based materials and biodegradable materials will be more widely used in the production of rotational molding products to reduce environmental impact. At the same time, the application of high-performance composite materials will enhance the weather resistance and impact resistance of rotational molding products, expanding their application fields. Furthermore, collaboration between upstream and downstream enterprises in the industry chain will become closer, jointly promoting the development of the rotational molding industry, forming a closed-loop industry chain that improves resource utilization efficiency. For example, collaboration between raw material suppliers, rotational molding equipment manufacturers, rotational molding product producers, and recycling companies will strengthen.
