For many plastic recycling companies, identifying and screening engineering thermoplastics is quite difficult, because it may contain a variety of different polymers, coatings and additives, plus metal parts and Other non-plastic parts and other materials, making recycling The difficulty and cost of such plastics have greatly increased. However, the US MBA Polymers company has adopted a new production line, which has greatly improved economic efficiency.

MBA Polymers uses an advanced engineering thermoplastic identification and screening system, as well as a small extrusion press. The former is used to separate engineering thermoplastics from many materials; the latter is used to make polymer particles, which are fed into molding equipment and made into a variety of specific shapes to suit different test requirements.

Taking a computer product as an example, the production line first grinds a large number of computer casings and other electronic waste into pieces, and then uses magnetic fields and a cyclone screening device to screen out iron and non-ferrous metals, and then separates the foam with jet air. Paper and other lighter weight materials eventually use a patented screening, cleaning, and testing process to further purify the remaining plastic and separate it into different types.

It is reported that the processing capacity of this production line is 6 times higher than the existing equipment, and the annual processing capacity is 40 million pounds.
