Plastic mold manufacturers, how to solve the odor problem during injection mold product processing.
When purchasing injection mold products, sometimes an odor may occur, which can have a significant impact on the health of the users.
How can we avoid generating odors during injection molding? Let’s briefly understand below.
1. Strictly control additive use: Catalysts such as tertiary amines used in the production of polyurethane foam can bring strong odors and cause fogging on the windows inside cars. By using hydroxyl compounds as substitutes for these amines, which not only form part of the polyurethane molecular chain but also exhibit catalytic activity, some hydroxyl compounds can even replace half of the tertiary amine catalysts, thus reducing the odor of injection molded products.
2. Choose purer resins: In many plastic molds, especially in polyvinyl chloride, styrene, polyethylene terephthalate, and acrylic resin, residual trace monomers can produce unpleasant odors. Opting for odorless resins can be more effective.
3. Pay attention to the use of adsorbents: Adding a small amount of zeolite in polymers can help eliminate odors. Zeolite has numerous crystalline voids that can capture gas molecules causing odors.
4. Odor issues during injection mold product processing require attention. Odors not only affect product quality and aesthetics but may also pose potential health risks to humans. Therefore, it is essential to find methods to address odor issues. By strictly controlling the use of additives, such as finding alternatives to tertiary amines with hydroxyl compounds, we can reduce the odor problem in products.
5. Choosing pure resins is an effective way to solve odor issues. In many plastic molds, residual trace monomers can lead to unpleasant odors. Therefore, selecting odorless resins can help minimize odor formation. Additionally, using adsorbents is effective. Adding a small amount of zeolite in polymers can assist in removing odors. Zeolite’s crystal pores can capture gas molecules causing odors, reducing the odor problem in products.
Solving the odor issue in the injection mold product processing requires considering factors like additive selection, resin purity, and adsorbent use. By rigorously controlling key production processes, selecting appropriate materials and additives, and taking suitable measures, we can effectively reduce odors in products, enhance product quality, and user experience. In injection mold product processing, focusing on product quality and user experience is crucial, striving to solve odor issues, and providing users with safer, healthier products.
