SG Die heads for compounding and masterbatch ©> AUTOMATIK Die heads or pelletizing units are used in strand pelletizing systems for extrusion of strand profiles. They are responsible for even strand flow and uniform pellet shape. SG series die heads have been specifically developed for applications in masterbatch, compounding and recycling processes. Adapted to your process and product, they can be used downstream of single or dual screw extruders, pumps or melt filters. Your benefits ■ Uniform and homogeneous melt distribution ■ Minimized dwell-time and short flow path of the melt ■ No separation or de-mixing of the components ■ Minimum pressure drop ■ Simple and easy cleaning ■ Mounting tool for the die plate ■ Cleaning Device for reduction of die drools (Hot-Air-Knife)

SG Die heads for compounding and masterbatch CFX Analysis Requirements for a uniform geometrical shape and the most uniform pellet size possible rank very highly. Pellets are produced by mechanical cutting of the melt or of the extruded strands. In designing and dimensioning the die heads, very complex physical relationships must be analyzed. When knowing the material properties and composition of the melt it is possible to design the perfect geometry of the die head. The following image shows, as example, the simulated shear rate in an insulated die head under adiabatic conditions. Depending...

Hot Air Knife (HAK) The Hot Air Knife (HAK) has been specially designed to reduce deposits at the die plate to an absolute minimum and increase efficiency of the extrusion process. It uses heated and pressurized air that eliminates die drool residues and thus avoids build-up of deposits which cause contaminations. The HAK is suitable for different operating sizes from 100 mm up to 900 mm and can be integrated directly at the die head or run by an autarkic control system, as shown below. This means in effect maximum flexibility regardless of the type of die head or other downstream equipment....
