Extrusion machinery group SML has released a new three metre wide machine for the production of enhanced stretch film for performance applications. Named SmartCast, the machine is a modular system with four pre-configured extrusion units at throughputs ranging from 1,700 kg/h to 2,400 kg/h and a choice of five or seven layers depending on requirements.
Using an optional edge encapsulation system, production speeds of up to 750 m/min are claimed to be achievable, which would provide an output on the winder of over 1,500 kg/h of 12µm film.
SML has also upgraded the chill roll unit by adding additional functions, avoiding vibrations and making operation easier. Also new from SML is the W4000-4S winder, which has been designed with the following features:
- Machine and jumbo rolls on 3-inch cores
- Hand rolls on 2-inch cores
- Coreless and thin core technology
- Reduced film tail for improved roll finish
The SmartCast line will be in operation on the SML stand (17/C42) at K 2013 in Düsseldorf.
