PET Sheet Extrusion Line Sale
The twin-screw extruder has unique merits to the process of polyester resins. Polyester is very vulnerable to thermal decomposition and hydrolyzation. Kerke has launched a new high-tech, lower-shearing, and low-temperature twin-screw extruder for the PET process, which streamlined the process, and portrayed advantages in energy-saving and end-product quality. As a result, the whole production cost has been contained.
PET Extrusion Line For Sale ( PP/PC/PS Sheet )
Energy-saving: twin screw extruder direct extrusion technology eliminated the necessity of pre-drying of polyester, thus the electricity can be saved up to 40%.
Product quality: thanks to the high-torque, low-shearing and low-temperature twin screw extruder, the lower process temperature can inhibit the negative effect caused by thermal decomposition demonstrably. Plus innovative high-efficiency vacuum system, the twin screw extrusion system can minimize hydrolyzation and oxidation as less as possible, which is harmful for polyester resins like PET/PC. Furthermore, the vacuum can remove some low molecular particles generated by the extrusion process; therefore the quality of final products has been raised.
Streamlined process flow:the pre-dry system has been removed from the process, the whole process flow has been streamlined which can bring down the investment, operation and production cost. In addition, the footprint, logistic and labor cost has been saved as well.
Wider tolerance of raw materials:the nature of self-wiping makes twin screw extruder more tolerate with the shape and bulk density of the raw materials. No matter pellets, powder, flakes, film even yarn can be taken easily. Not only has the pre-dry process been eliminated, but the pelletizing process has been spared too.
Cost containment: each merit above mentioned can save cost directly and indirectly.
