With the CTE 50 PLUS Coperion Nanjing, China, launches its new CTE PLUS twin screw extruder series at Chinaplas 2015 (Guangzhou / PR China, May 20-23, 2015). The CTE PLUS is equipped with a new gearbox engineered by Coperion Stuttgart, Germany. It offers a new terminal box that meets highest safety standards and is supplied on a unitized base frame. The series offers a very attractive cost/performance ratio and its precise manufacturing ensures the economical processing of a wide range of applications at high product quality. Before delivery each CTE PLUS extrusion system is subjected to a Factory Acceptance Test (FAT) at the Coperion Nanjing site to ensure high quality standards. As an option, the CTE PLUS series can be provided with CE certification. The CTE PLUS series is making its world public debut at Coperion’s booth n. 5.1K11 in hall 5.1. at this year’s Chinaplas.

New gearboxes for CTE PLUS series

To improve reliability and to ensure longer life time Coperion Stuttgart, Germany, has engineered new gearboxes for the CTE PLUS that can bear a specific torque of 7.2 Nm/cm³ and are exchangeable with old generation CTE’s gearboxes. The rotating parts and bearings of the new gearboxes have been redesigned, tooth width has been enlarged and tooth flank and profile have been optimized to ensure a perfect intermeshing surface. The new gearboxes offer improved cooling and oil supply and the geometry of their housing has been optimized for higher stiffness and prevention of vibrations. The gearbox housings are all manufactured in-house at Coperion Nanjing. After production all gearbox housings are checked in-house with a 3D inspection machine to ensure dimensional precision up to 1.4 μm. Every single CTE PLUS gearbox is subjected to almost 40 inspection items.

Improved quality standards at Coperion in Nanjing

Coperion Nanjing - the production site of the CTE series - has implemented comprehensive standards to improve production quality. Coperion Nanjing is using numerous modern, German supplied machining centers and quality check instruments. The state-of-the-art CNC machining centers for the production of barrels and screw elements as well as the inspection centers for barrels, screw elements and gearbox housings ensure high production quality.
