This extruder was developed originally for the production of fishing bait for the sport fishing industry but is suitable for any application which requires the production of a line of product from a pre-mix. The extruder is compact, rugged, simple to set up and operate and can be customised to produce a shaped line of product or (with a cutter as shown below) line segments or pieces for roller shaping.
