Coperion  ZSK 26 Mc18 extruder

Coperion and Coperion K-Tron at Chinaplas 2014

Stuttgart, March 2014. – One of the latest developments of Coperion GmbH, Stuttgart/Germany, to make its debut in Asia is the ZSK 26 Mc18 twin screw laboratory extruder with 25 mm screw diameter.

This new extruder, which will be shown on Coperion's booth E1J01 in Hall E1, offers all the advantages of the ZSK Mc18 series; it has a simple design, it is operator-friendly and easy to clean. It is suitable for the development of formulations, for conducting sample compound trials and for the production of relatively small batches with up to approximately 180 kg/h. Compared to its predecessor, the ZSK 26 Mc, this newly developed laboratory extruder of the ZSK Mc18 series is capable of an increase in throughput of up to 100%, as the specific torque has been increased to 15 Nm/cm3, and is more energy efficient thanks to the reduced specific energy input. The increased filling degree and the lower melt temperatures ensure extremely gentle product handling. The new ZSK 26 Mc18 is a mobile unit and requires only a minimum of floor space, as the control cabinet is integrated into the base frame of the machine. Heating and cooling are installed ready for use.

STS advanced twin screw compounder – Proven quality for plastics applications

Also on display is Coperion’s STS 65 advanced compounder with 65 mm screw diameter and a specific torque of 10 Nm/cm³. Thanks to this high torque, the STS standard twin screw compounders achieve not only very good product quality but also maximum throughput rates. The series is equipped both with a powerful motor and with a gearbox rated for the required torque.

Coperion’s further development of the STS advanced has benefited considerably from the company’s vast experience gained with the high-end ZSK series. The STS advanced series unites the advantages of a largely standardized and hence cost-efficient machine with the processing know-how acquired by Coperion over many years. A decisive factor for the improvement in compound quality is the relative increase in the amount of material passing through the extruder process section. This reduces the specific shear stress, lowers the melt temperature and improves the mixing performance. As a result, the STS advanced operates with a gentler compounding action as well as higher efficiency and product quality. Since it offers an excellent price-performance ratio, the compounder pays for itself within a short time.

Precise metering, registering and monitoring of bulk material flows

Coperion K-Tron introduces the newly redesigned Smart Flow Meter which is used in industries that need reliable metering, registering or monitoring of bulk material flows. In high rate applications, the Smart Flow Meter provides high accuracy feeding, at very high feed rates of up to 200 m³/hr (7,000 ft³/hr). Applications include material flow control within a production line, measuring filling or discharge of materials from storage, inventory control, and quantitative bulk goods measurement. The Smart Flow Meter offers lower maintenance costs, reduced headroom and is a cost-effective solution for in-line weighing applications. There are two models available: K-SFM-275-B and K-SFM-350-B, dependent on application requirements. The Smart Flow Meter is often used in polyolefin production processes, where the main component is accurately and gently fed into the extruder.
