Yellow Jacket® Table Top Extruders were the first extruders manufactured by Wayne Machine and have a long, proud history. Compact and lightweight, they are ideal for research, testing, quality control, and production applications. The extruder screw is easily removed for quick and easy cleaning when cross contamination is a concern. Wayne Yellow Jacket® Table- Top extruders are extremely versatile and are often used as lab extruders, main production extruders or as co-extruders. Wayne custom builds these extruders for special applications such as high temperature or corrosive polymer processing. Wayne Yellow Jacket® Table Tops 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
• 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.
• Yellow Jackets feature a Heavy duty thrust bearing section. Many other lab extruders use only the gearbox bearings to bear the thrust and this leads to premature gearbox failure.
• The downstream end of the barrel is supported for strength and die stability during operation.
• The toothed timing belt drive allows for easy speed range changes when compared to directly coupled motor and gearbox designs.
