Many injection mold processing products will have peculiar smell during processing, and users will feel uncomfortable, so how to avoid this situation during mold injection molding? Injection mold processing manufacturers are at your service. 1. Strictly control the use of additives The tertiary amine catalyst used in the production of polyurethane foam usually causes a very strong odor, and moisture in the window of the car, we can find that instead of using polyols, the composition of polyols is not only polyurethane molecular chains, But it also has the same catalytic activity, and some polyols can even replace half of the tertiary amine catalyst, so the odor of injection molding products disappears. 2. Use more pure resin Many plastics, especially polyvinyl chloride, styrene, ethyl acetate, acrylate, and other residual trace monomers, produce odor.

Very little monomer residue can be used to remove odors, and it is better to choose an odorless resin. 3. Pay attention to the use of adsorbents. If a small amount of zeolite is added to the polymer, the smell of information can be removed. Zeolite crystals have a lot of haze, which traps small molecules like gases.
