At CHINAPLAS, Coperion GmbH and Coperion K-Tron will present their latest technologies for plastics processing. Exhibits on display include a ZSK 70 Mc18 twin screw extruder with a Coperion K-Tron T35 twin screw loss-in-weight feeder. Further on display is an STS 25 Mc11 laboratory twin screw extruder with a NT28 feeder from Colormax Systems.
Both compounding systems are suited for current challenges of the plastics industry such as recycling or the production of biodegradable plastics. Additional high-accuracy and flexible feeding solutions will be on display: a Colormax Systems V50 vibratory feeder as well as a complete Coperion K-Tron system in a mobile frame consisting of a T35 Quick Change twin screw loss-in-weight feeder outfitted with ActiFlow smart bulk solid activator, Electronic Pressure Compensation (EPC) and a 2415 vacuum receiver for refill.
At the Coperion booth, visitors can also learn about the advantages of Coperion MTS Modular Turnkey Solutions. These smart compounding lines include first-class Coperion and Coperion K-Tron technology for all process steps and are tailored to the Asian market.
Extruders for various plastics processing applications
As a representative of its high performance ZSK twin screw extruder series, Coperion will exhibit a ZSK 70 Mc18 extruder with 70 mm screw diameter at the show. With the specific torque of max. 18 Nm/cm3 it reaches very high throughput rates and end-product quality.
ZSK extruders offer high flexibility, reliability and economical production. The ZSK 70 Mc18 extruder on display is designed for the production of engineering plastics and reaches throughputs of 1200 up to 1600 kg/h. It will be displayed with a highly accurate Coperion K-Tron T35 gravimetric twin screw feeder.
ZSK 70 Mc18 extruder
Coperion will also present an STS 25 Mc11 laboratory extruder with a 25 mm screw diameter that boasts the advantages of the STS Mc11 series. It has a simple design, is operator-friendly and easy to clean. The base frame has a closed, simple-to-clean surface and is equipped with castors for easy movement of the extruder and fast installation.
By having the same screw diameter ratio Do/Di of 1.55 and specific torque Md/a3 of 11.3 Nm/cm3 as the whole STS Mc11 extruder series, production parameters of the STS 25 Mc11 can be scaled up to larger STS sizes. It is also suited for the production of small batch sizes of 2 kg and more and achieves throughputs of up to 80 kg/h.
The STS 25 Mc11 which Coperion will exhibit at CHINAPLAS will be shown with a C/S-LW-NT28 twin screw loss-in-weight feeder from Colormax Systems.
K-Tron feeders for high flexibility
Also on display will be a highly accurate Coperion K-Tron K2-ML-D5-T35/S60 Quick Change feeder (QC), featuring the ActiFlow smart bulk solid activator and Electronic Pressure Compensation (EPC) in combination with a 2400 Series vacuum receiver for refill.
The QC feeder is designed for applications requiring quick changeover of materials and convenience of fast cleaning. Twin and single screw feeding modules are available. Single screw feeding units handle free flowing powders, granules, pellets and other non-flooding materials, while twin screw units are suitable for floodable powders and more difficult, sticky or hard-to-flow materials.
The ActiFlow smart bulk solid activator offers an innovative method to reliably prevent bridging and rat-holing of cohesive bulk materials in stainless steel hoppers without internal hopper agitation.
ActiFlow is a non-product contact device, consisting of a patent-pending vibratory drive and intelligent control unit, designed specifically to work with Coperion K-Tron’s line of gravimetric loss-in-weight feeders.
Proven modular turnkey solutions
At CHINAPLAS, Coperion also presents its compounding lines that are developed with focus on the Asian market. These pre-configured compounding lines include first-class Coperion and Coperion K-Tron technology for all process steps: from raw material handling to feeders, the Coperion STS Mc11 twin screw extruder and strand pelletizer as well as conveying and bagging solutions.
The smart concept comprises a high level of automation with digitalization and optimized handling of powders to maintain a clean production area. Furthermore, Coperion offers support for building design which includes all requirements for the logistics of raw material delivery and handling finished goods as well as space for maintenance.
