Coperion STS 35 Mc11 Twin Screw Extruder

Plastimagen 2019: Perfect Solutions for Masterbatch Compounding

Sewell, NJ, USA, March 2019 – At this year’s Plastimagen show (April 2-5, 2019, Centro Citibanamex, Mexico City) Coperion will present an STS 35 Mc11 twin screw extruder for masterbatch that features a series of improvements for safer working and improved cleaning, such as a new base frame design, reengineered extruder covers and a new die head specifically developed for producing color masterbatch. Also on display will be a Coperion SP 50 pure strand pelletizer and a Coperion K-Tron gravimetric screw feeder, ideally suited to the production of masterbatch to ensure a continuous, uniform infeed.

Coperion Twin Screw Extruder STS Mc11 Ideal for Color Masterbatches
The STS 35 Mc11 twin screw extruder features a specific torque level of 11.3 Nm/cm3, screw speeds of up to 900 rpm, and proven Coperion extruder quality. The full line of STS extruders offers an extremely appealing price/output performance ratio. With color masterbatch processing in mind, Coperion equipped the STS Mc11 twin screw extruder with new features that significantly improve the system’s handling and ease of cleaning. The STS Mc11 now includes a new base frame design which allows for integration of the water manifold and wiring connections for better cleanability without sacrificing accessibility.

Coperion Pelletizing Technology Strand Pelletizer SP 50
The strand pelletizer SP 50 pure on display is ideal for longtime operation due to robust functions such as the rugged housing for sturdy cutting gap and high cutting quality over the whole working width. The cantilevered bearing design offers easy access and quick cleaning. The vibration insulation and many other useful options such as pellet length regulation, driven upper feed roll, cutting head cooling or transfer signal to the extruder control, which are available for the different pelletizers of Coperion Pelletizing Technology, ensure gentle product handling and best pellet quality.

Coperion K-Tron Twin Screw Compact Feeder Optimal Solution for Feeding Difficult Materials
The Coperion K-Tron KT20 twin screw feeder with interchangeable feeding tools is mounted on a 24 kg fully enclosed platform scale for high accuracy feeding of difficult flowing ingredients. All feeder parts in contact with the material being fed are stainless steel, and feeding equipment is easy to disassemble. A horizontal agitator gently moves the bulk material to the large throat and then into the screws. Twin screw feeders are ideal for floodable powders and more difficult, sticky or poorly flowing materials, as well as fibers or flakes. Specialty designs are available for clustering of feeders above extruders, blenders and other processes for optimal accessibility and ease of cleaning.
