CPM develops standardised GXT twin-screw extruders
The Process Solutions business of CPM is working on a new product line of twin-screw extruders dubbed GXT, short for Global eXtruder Technology. The GXT is a standardised line that can be manufactured at all of CPM’s global manufacturing facilities for the benefit of regional customers. CPM is developing the GXT in
response to customer demand. “We have a constant ‘can this be done’ process with our customers,” said Sean Doran, Vice President of Engineered Materials, speaking to Compounding World at NPE 2024. In this instance, customers have been asking CPM about reducing overall operational cost in their use of twin-screw extruders. Doran said that technology trends
have usually focused on performance improvements, such as higher RPM and higher torque. But the company observed what customers were actually doing operationally, he said, and often they were not running their extruders at the higher RPM and torque levels. Standardisation is the main concept in the GXT development, but Doran stressed CPM is standardising around its proven technology, not as part of cost-cutting in the engineering of the GXT. The GXT extruders are available in standard centreline geometries, 13 Nm/cm³ torque densities and any- where from 40 to 48 L/D. The company is in the process of making final decisions on sizes and models, but it is able to take orders and start building
machines for customers right now. The standard Do/Di 1.55 extruder is the basis for the GXT design, as it is widely used in the industry. “We know the 1.55 has been an effective work- horse,” said Doran. The GXT is a standardised solution suitable for nearly all compounding applications, says CPM. It is a plug and play design and offers benefits to customers such as improved delivery times, as well as the reduction in operating costs that customers have requested. Doran said the company is confi-
dent that customers will appreciate the low cost of ownership of the GXT, plus its reliability and flexibility. �
