use rare earth magnets to hold and remove small ferrous metal contamination. The five metal detectors displayed are designed for installation at different stages within the manufacturing process and to handle specific materials. For example, the QuickTron 05 and 03R models detect and separate metal contamination in free-fall applications. �

At K2022, Collin Lab & Pilot Solutions demonstrated a medical tube line with its new VKT 3000 vacuum water bath. The line included an extrusion unit with an E 25
P extruder, as well as a lift extruder, strip die and new 3000mm water bath – with optimised, closed- water circulation and vacuum calibration unit. The line enables high precision in roundness and constant tube diameter with up to five layers. The water bath is followed by diameter measurement, a take-off unit and a Collin winder for tubes. “With this line, tubes for minimally invasive
procedures, dialysis, catheter, infusion or drainage tubes or drug-loaded strands can be produced,” said Friedrich Kastner, CEO at the company. “It has a line speed of up to 200 m/min and a diameter range of highly precise tubes of 0.5 to 5mm.” Collin water baths are available in different lengths – for horizontal and vertical tube guiding. Due to the modular design, several water bath units can be arranged in series. This allows water baths with lengths up to 15 m and speeds up to 200 m/min. “The advantage of our tube lines is that they can

be arranged in a modular way with different machine elements for different requirements, depending on the customer requirements – and can be used for non-medical applications,” added Corné Verstraten, CSO at Collin. �

Delta Tecnic of Spain has introduced a range of masterbatches for PVC window profiles. The colour PVC masterbatches are designed to
provide fast dilution, high colour consistency and weather resistance. Popular colour options for window profiles include browns, creams and greys. The company offers PVC masterbatches in a range of shapes and sizes including very fine Criopellets with particle sizes less than 1,000 microns, small micro pellets, micro pellets and standard pellets. Area manager Filipa Martins says that using masterbatch rather than powder pigments is a cleaner solution for profile extruders producing their own compounds – and also shortens cleaning times. In addition, it is offering new colour masterbatches for recycled PVC in black, white and brown. These all have high concentrations of pigments and are formulated to deliver good dispersion. The white masterbatch has a high content of titanium dioxide and other ingredients to help restore the appearance of recycled white PVC that has yellowed over its lifetime. A new conductive formulation for cable
applications combines carbon black with graphene to enhance EMI shielding. It is currently in a trial phase. The company already has a range of commercial conductive products based on carbon black and carbon nanotubes. �

At K2022, 3S – part of Erema – presented innovations in wear measurement and screw production. It demonstrated how a new type of cylinder enables ultrasonic wear measurements – and a new screw manufacturing technology leads to more efficient production. The company is a specialist in the manufacture of extruder screws for plastics and recycling, and each year processes between 1,500 and 2,000 screw and cylinder orders. The company has developed a new type of cylinder that enables ultrasonic wear measurement of the extrusion screw and cylinder while the machine is running.
