HKY / SKY Two Stage Extruder
https://www.keyatwinscrew.com/products/sky-two-stage-extruder/
HKY / SKY series two-stage extrusion system: the first stage is HK or SK series high speed and high torque co-rotating twin screw extruder, the second stage is single screw extruder to form a two-stage compound extrusion system.
The system combines twin screw high speed, strong mixing with single screw low speed, low temperature and weak shearing characteristics to enhance advantages and avoid disadvantages. It is the preferred model for mixing and modifying heat-sensitive and shearing-sensitive materials efficiently nowadays. The main granulation methods are air-cooled hot cutting and eccentric water mist granulation. They can also be matched with drawing strip cold cutting and water ring hot cutting.

SK53 Twin Screw Extruder
https://www.keyatwinscrew.com/products/sk53-twin-screw-extruder.html
Overview of SK53 Twin Screw Extruder
SK53 mini twin screw extruder can be used in engineering plastics, color masterbatch, functional masterbatch, blending modification and other industries.
In order to adapt to the high temperature and high wear resistance of Engineering plastics, HIP hot isostatic pressing technology is used in the material selection of cylinder and screw for SK53 twin screw extruder.

It has the advantages of high wear resistance and corrosion resistance; for example, when the customer's working formula in PA, PP + glass fiber or carbon fiber + flame retardant, it is recommended to use high wear resistance material (SAM10); if the customer's working material not only requires to wear resistance but also has certain acidity and alkalinity, it needs to consider using corrosion resistance material (SAM26/39). In view of the lateral forced feeding of carbon fibers, a special feeding screw design is adopted, which effectively solves the problem that the material is fluffy and can not be fed
Hot isostatic pressing (HIP) is to place the product in a sealed container and apply the same pressure in all directions to the product. At the same time, SK53 mini plastic twin screw extruder machine can be sintered and densified under the action of high temperature and high pressure. Thermo-isostatic pressure is an indispensable means and technology for the production of high performance materials and the development of new materials.
