In the production process of plastics and rubber, the misinsertion and wear of iron sheets and metal powders can affect product quality and finished product qualification rate. To solve these problems, magnetic separators are widely used in the rubber and plastic industry. Different types of plastics such as PET, PE, PVC, PP, PS, PC, as well as modified plastics in industries such as production, granulation, and injection molding of engineering plastics such as PA, POM, ABS, PTFE, PSF, PI, LCP, PPS, and PEEK can use magnetic separators to remove impurities.
magnetic separators have various product features, including semi-automatic/automatic removal of ferromagnetic powders, particles, and iron oxide, capturing small weakly magnetic impurities, ensuring the safety and product quality of subsequent production lines. Commonly used magnetic separator products include magnetic rods, magnetic grids, drawer magnetic separators, and rotary magnetic separators.
A successful case is an engineering plastic production enterprise whose plastic particles are mainly supplied to the automotive industry, with a finished product qualification rate of only 96%. After analysis, it was found that the plastic particles contained fine iron impurities inside. Traditional metal detection tests cannot capture these impurities. To solve this problem, after repeated tests, it was recommended to use a strong magnetic roller type magnetic separator to remove iron inclusions. After use, the finished product qualification rate for automotive parts users increased to 98%. Now, all 12 production lines of the company have added strong magnetic roller type magnetic separators, which have been running stably for 2 years.
