Viet UC Mechanics Polymer, a Vietnamese manufacturer of plastic materials, specializes in the production of masterbatch, plastic additives, pigments, PVC additives and plastic resins. The company was faced with the challenge of eliminating metallic impurities in the masterbatch. This is to prevent particles from entering the plastic mixtures during production. These impurities could not only affect the quality of the end product. They also cause machine downtime and customer complaints. To ensure the quality and purity of their products, it was necessary to find a reliable metal detector that is sensitive enough to detect and remove even the smallest metallic particles (ferrous 0.39 millimeters, non-ferrous 0.5 millimeters, stainless steel 0.5 millimeters). They also had to ensure that the solution would work effectively with challenging product effects, such as dark coloration, especially black masterbatch.
Metal separator for reliable and precise metal separation
After a thorough market analysis, Viet UC decided to implement the Rapid Vario metal separator from Sesotec. The device has been specially developed to detect and separate metallic contaminants in bulk materials, even if they are deeply embedded in the product. The unit is characterized by high sensitivity, easy integration into existing production lines and reliable performance. The Sesotec solution included a feature that automatically or manually adjusts to different product effects. These can be, for example, electrical conductivity and color variations in black material.
In the plastics industry, the masterbatch can contribute to the product effect. This is because some additives or fillers can make it more difficult to detect metal contaminants or affect the detector. Metal detectors and separators are designed to be sensitive enough to detect metal contaminants while compensating for the product effect as much as possible. These systems were installed at Viet UC before filling into 25-kilogram bags to ensure that the products are consistently free of metal. The first unit was installed in September 2023, followed by a second unit in May 2024.
Metal separator improves product quality, customer trust and processes
The implementation of the metal separator has paid off for Viet UC in many ways, particularly because the company places a high value on quality assurance. First of all, product quality has been significantly improved, leading to increased customer satisfaction. Returns and complaints due to metal contamination are a thing of the past. In addition, potential machine damage and expensive production downtime have been avoided thanks to the reliable detection and removal of metal particles.
Viet UC plans to continue investing in recycled materials such as PP and HDPE and to use Sesotec equipment to test these new product lines as well. This partnership with Sesotec supports the company in its vision of global expansion and meeting the highest quality standards. “By installing the Rapid Vario metal detector, we have been able to significantly increase the quality of our masterbatch products. Our customers now have full confidence in the purity of our deliveries. Sesotec has helped us not only to optimize our internal processes, but also to improve our reputation with end customers”, says Nguyen Van Phuong, Technical Manager at Viet UC Mechanics Polymer.
Conclusion: metal separator optimizes production processes and thus business relationships
In summary, the Sesotec solution has not only optimized Viet UC's production processes, but has also brought long-term benefits for the business and customer relations.
