What should we do to reduce the emission level of these odors? Let me introduce how to reduce the generation of peculiar smell in plastic injection molds. 1. Strictly control the use of additives. The catalyst tertiary amines used in the production of polyurethane foam often bring strong odors and fog on the inner windows of cars. We can find substitutes for these amines and use polyols , polyols are not only components of the polyurethane molecular chain, but also have catalytic activity, and some polyols can even replace half of the tertiary amine catalysts, so that the odor of injection molding products will become lighter. 2. Use more pure resins. In many plastics, especially in plastics such as polyvinyl chloride, styrene, polyethyl acetate and acrylate, the residual trace monomers will produce unpleasant odors. Very little resin is needed to eliminate those odors.If the resin itself is odorless, it will also have a good effect. For example, a plastic parts processing factory has developed a new grade of acetal copolymer, which releases a very small amount of odor during the injection process. 3. Pay attention to the use of adsorbent. If a small amount of zeolite is filled in the polymer, it can remove the odor of the material. Zeolite has many crystal voids, which can capture small gas molecules with odor.

Rotational molding and injection molding are both popular methods used in the production of plastic products. While they may seem similar at first glance, there are significant differences between the two processes. In this article, we will explore the similarities and differences between rotational molding and injection molding to help you better understand which method may be best suited for your manufacturing needs.
Rotational Molding
Rotational molding, also known as rotomolding, is a manufacturing process that involves heating and rotating a hollow mold filled with a powdered material, typically plastic resin. The mold rotates on two axes simultaneously, allowing the material to evenly coat the interior walls of the mold as it melts and fuses together. Once the material has cooled and solidified, the mold is opened, and the finished product is removed. This process is ideal for creating large, hollow plastic products with uniform wall thickness and excellent strength.
One of the key advantages of rotational molding is its ability to produce complex shapes with relatively low tooling costs. Since the molds used in rotational molding are typically made from aluminum or steel, they can be easily modified or replaced as needed. Additionally, rotational molding is a low-pressure process, which means that there is less stress on the material during production, resulting in stronger, more durable products.
However, rotational molding does have some limitations. Because the material is heated and rotated slowly in the mold, the cycle times for rotational molding are typically longer compared to other molding processes. This can result in lower production output and higher manufacturing costs, making rotational molding less suitable for high-volume production runs.
Injection Molding
Injection molding is a manufacturing process that involves injecting molten material, typically plastic resin, into a mold cavity under high pressure. The material is forced into the mold, where it cools and solidifies to form the desired shape. Injection molding is commonly used to produce small to medium-sized plastic parts with complex geometries and tight tolerances.
One of the main advantages of injection molding is its ability to produce high-quality, precise parts with fast cycle times. Injection molding machines are capable of producing thousands to millions of parts per day, making it an ideal choice for high-volume production runs. Additionally, injection molding allows for the use of a wide range of materials, including thermoplastics, thermosets, and elastomers, giving manufacturers flexibility in material selection.
However, injection molding also has its drawbacks. The initial tooling costs for injection molding can be high, especially for complex molds with intricate designs. Additionally, injection molding requires uniform wall thickness to prevent defects such as warping or sink marks, which can add to the complexity and cost of production.
Key Differences
While rotational molding and injection molding share some similarities, there are several key differences between the two processes. One of the most significant differences is the way in which the material is introduced into the mold. In rotational molding, the material is added as a powder, which is then heated and melted in the mold. In contrast, injection molding uses molten material that is injected into the mold under pressure.
Another difference between rotational molding and injection molding is the cooling time. Rotational molding typically requires longer cooling times due to the slow rotation of the mold, whereas injection molding has faster cycle times thanks to the high pressure used to force the material into the mold cavity.
The cost of tooling is also a significant factor to consider when choosing between rotational molding and injection molding. Rotational molding molds are generally less expensive than injection molding molds, making rotational molding a more cost-effective option for smaller production runs or products with lower complexity. In contrast, injection molding molds can be costly, but the high production output and quality of the parts make it a preferred choice for high-volume manufacturing.
Material Selection
Another important consideration when choosing between rotational molding and injection molding is the type of materials that can be used in each process. Rotational molding is best suited for materials that can be ground into a fine powder, such as polyethylene, PVC, and nylon. These materials melt easily in the mold and have good flow properties, making them ideal for rotational molding.
Injection molding, on the other hand, is more versatile when it comes to material selection. In addition to thermoplastics like ABS, polycarbonate, and polypropylene, injection molding can also process thermoset materials like silicone and epoxy resins. This flexibility in material selection gives manufacturers more options when it comes to choosing the right material for their specific application.
Conclusion
In conclusion, while rotational molding and injection molding are both effective methods for producing plastic products, they each have their own strengths and weaknesses. Rotational molding is ideal for creating large, hollow parts with low tooling costs, while injection molding is better suited for high-volume production runs of smaller, more complex parts.
When deciding between rotational molding and injection molding, it is essential to consider factors such as production volume, part complexity, material selection, and tooling costs. By understanding the differences between these two processes, you can choose the method that best meets your manufacturing needs and allows you to produce high-quality plastic products efficiently and cost-effectively.
