Wayne Yellow Jacket® Small Floor Model extruders are used primarily as main extruders in applications demanding a rigid floor mounted machine. These applications might be in a production situation where the extruder is required to have a minimum vibration for precision extrusion or the floor model extruder might be used as the basis of a co-extrusion system which requires at least one rigid extruder. Wayne custom builds these extruders for special applications such as high temperature or corrosive polymer processing. These extruders can also be built with 90 degree panels for use in crosshead die extrusion such as in tubing, wire insulation and fiber optic sheathing applications. Wayne Yellow Jacket® Small Floor Model extruders have some unique advantages over competitively sized extruders and these are as follows:

• No worm drive gearbox - All Wayne extruders use double reduction helical gearboxes for less gear wear, less gearbox frictional heat and more efficient power transmission to the screw. This results in reduced stalling and more stable output as required for laboratory tests and production applications.
• One piece barrel with EDM feed hole means Yellow Jackets have full wear resistant bimetallic lining in the feed section that can't be misaligned as opposed to competitive machines that have separate soft stainless steel feed sections which wear out easier and are easily misaligned during operation and maintenance causing screw damage
• Higher horsepower drives are available- for example our 1" floor model has 5HP which is 67% more horsepower than a 3HP competitive model.
• Industry standard feed end driven screws are used for easy scale up to production machines without translation losses.
• Since no dynamic seals are required, all the problems that can be caused by them including seal surging, polymer stagnation and degradation and flooding of the gearbox with polymer when the seals wear and fail, are eliminated.
• Screw break protection and deformation prevention are achieved through the use of high strength screw alloys and advanced electronic torque limiting features of the drive.
• The toothed timing belt drive allows for easy speed range changes when compared to directly coupled motor and gearbox designs.
