How can plastic mold manufacturers avoid the odor generated during the production of plastic molds
Date: March 27, 2024
When purchasing injection molded parts, sometimes there may be an odor, which has a significant impact on the user’s physical health. So, how can we avoid producing odors during injection molding? Below, we will explore some methods to solve this problem.
Firstly, we can strictly control the use of additives. The tertiary amine of the catalyst used in the production of polyurethane foam will bring a strong smell, and even fog on the interior window of the car. To alleviate this odor, we can consider using polyhydroxy compounds instead of tertiary amines, as polyhydroxy compounds are not only components of polyurethane molecular chains, but also have catalytic activity. Some polyhydroxy compounds can even replace some tertiary amine catalysts, thereby reducing the odor of injection molded products.
Secondly, selecting purer resins is also an effective method. In many plastic molds, especially in materials such as polyvinyl chloride, styrene, polyvinyl acetate, and acrylic esters, residual trace amounts of monomers can cause unpleasant odors. Therefore, choosing odorless resins can effectively reduce the generation of odors.
Additionally, paying attention to the use of adsorbents is also an effective method. Adding a small amount of zeolite to the polymer can remove the odor of the material. Zeolite has many crystalline voids that can adsorb gas molecules with odors, thereby purifying the odor of the product.
Plastic mold manufacturers, by strictly controlling the use of additives, selecting pure resins, and paying attention to the use of adsorbents, can effectively avoid the production of odors in injection molded products and ensure the health of users. In the injection molding process, we should pay attention to details and solve the problem of odor from the source, striving to produce high-quality, odor free products.
The above are some discussions on how to avoid odors in injection molding processing, hoping to be helpful to you. May our production environment be cleaner and healthier, and contribute to the sustainable development of society.
