Given the growing needs of a market in continual evolution, BD Plast has improved its range of screenchangers and introduced a new line of products. It has added extrusion necks, curves and couplings to its range of products offered to OEM and to final users. The outcomes of this development process was presented at PLAST 2012, where the company unveiled a platform on which a group of necks and curves for a five-layer flat-head coextrusion line were installed, complete with wired heaters and five manual and hydraulic screen changers. A hydraulic single plate screenchanger for high production loads and a constant flow double screenchanger with a completely revised layout and sealing system were exhibited to complete the range.
