Bausano , a leading international player in the design and production of customised extrusion lines for plastics processing , is not only driving technological progress in the production of extrusion lines , but is also strengthening its R & D department and reinventing the concept of innovation with the introduction of new analysis tools and doubling the space dedicated to testing . To this end , Bausano provides a wide range of services through which customers can experience the company ‘ s quality in the design of their systems . Thanks to the dedicated test and experimentation laboratory , in fact , Bausano offers an exclusive working method , which starts from the customer ‘ s specific formulation to elaborate structured analyses , aimed at making each extrusion line completely tailormade . Indeed , before designing a system , analyses are carried out at Bausano using the capillary rheometer , which studies the behaviour of the material when it flows and deforms , in order to understand its viscosity as a function of the shear rate gradient . With rheological material characterisation , Bausano is able to :
1 ) define the type of materials that can be extruded on an existing plant ; 2 ) optimise head design ; 3 ) fine-tuning the design of the screws .
At the same time , the information collected is processed using a plastograph . Here , the customer ‘ s starting materials are fed into the chamber , where they are heated and undergo shear stresses between two counter-rotating rotors . During machining , the torque applied to the rotating screws is measured , which provides information on the viscosity of the molten material and thus on any changes produced by machining on the system ( gelation , branching , degradation ).
DEVELOPMENT OF NEW PRODUCTS The result of these analyses , a fundamental and distinctive preliminary step in Bausano ‘ s know-how , is compared with data
