Welex Incorporated announced today that it has sold the first Welex Converge CTS™ Sheet Line. This dryer-less solution will feed an inline PLA/PET thermoforming system at a leading North American packaging supplier, obviating the need and expense of conventional drying and recrystallizing systems.

‘CTS stands for ‘conical twin screw’’ explains Welex Director of Sales Jim Nissel, who has completed trials over the past several years and applied extensive Welex processing knowledge to bring this new line to market. ‘Welex opted to build this new dryer-less solution using conical twin screw technology which we have tested and found to be superior to parallel twin screw: better feeding characteristics for low bulk densities, higher pressure and torque capability, the lowest possible melt temperature, a reduced footprint, and significant energy savings versus parallel twin screw technology,’ says Nissel. ‘It also permits the addition of inexpensive fillers such as talc and calcium carbonate without the addition of expensive side feeding systems.’

‘With solutions installed in more than 3,000 customer locations in 69 countries, including over 500 PET sheet lines, Welex is the leader,’ adds Welex Vice President of Sales – Americas, Hayes Stripling, who was also involved in the development. ‘We are now able to offer our customers a full range of options, from a traditional single screw line to the new Welex Converge CTS™ Sheet Line with high vacuum moisture removal, both with the Welex Evolution® Sheet Take-Off.’

‘We have more than a dozen active proposals in North America, Latin America, Europe, APAC and the Middle East, and are pleased to find such a receptive market for the superior performance the Welex Converge CTS™ Sheet Line presents,’ states David Schroeder, Welex President & CEO. ‘It is great validation for the time and effort invested in its development.’
