A 3-D CAD system with finished elements analysis module is used to evaluate the mechanical and thermal solicitations. The screws geometry allows the machine to process the material in a soft way, by keeping a proper energetic supply of motor, material and heating system; therefore a better quality of the extruded product is achieved with a high output rate. The project parameters of the screws, such as the compression ratio and the chambers filling, enables us to obtain proper cutting actions, with remarkable advantages for a longer life of the screws and barrel. On the barrel, the temperature control system is made through the following manufacturing features: \u2022 barrel heating through a low-thermal-inertia system for an accurate control of the temperature; \u2022 cooling system by high capacity blowers and highly efficient thermal dissipaters for thermal exchange or, in the bigger models, by oil forced circulation in a spiral circuit integrated in the barrel; \u2022 L-distribution of the heating elements in order to keep the temperature constant and avoid any possible thermal deformation of the barrel; \u2022 set temperature control through P.I.D. algorithms.

A 3D CAD system with finished elements analysis module is used to evaluate the mechanical and thermal solicitations. For a further improvement of the quality of the melt characteristics and at the same time to satisfy some particular working requirements, the screw can be featured by mixing zones with dispersing and distributing elements with characteristics suitable for the different applications. The wide range of geometries allows optimizing the performances. In fact there are available screws: \u2022 dedicated to particular materials to maximize the performances; \u2022 multi use to reconcile versatility and performance. Screw and barrel can be in execution for single or double vent system through water-ring pumps and, for particular requirements like high vacuum level, through dry-pump groups. On the barrel, the temperature control system is made through the following manufacturing features: \u2022 positioning and dimensioning of the temperature control zones according to the different screw geometries; \u2022 cooling system by high capacity blowers and highly efficient thermal dissipators for thermal exchange; \u2022 L &#8211; distribution of the heating elements in order to keep the temperature constant and avoid any possible thermal deformation of the barrel; \u2022 set temperature control through P.I.D. algorithms.<\/p>\n<p>The most suitable screw geometry is selected by means of a computer assisted design system in accordance with the chemical\/ physical characteristics of the solid-state material and with the rheological data of the melt.

The project parameters of the screws, such as the compression ratio and the chambers filling, enables us to obtain proper cutting actions, with remarkable advantages for a longer life of the screws and barrel. The vent system allows an efficient evacuation of the volatile elements during the fusion process. The vacuum unit, easily accessible, is protected by a filtration group equipped with bypass which avoids any interruptions during the maintenance operations. Thank to our long experience, JINHAI has also developed specific screw geometries for different applications, obtaining a very good thermic stability at low working temperatures and high performances also with an absorbed power extremely reduced. In this case also, thanks to the different technical solutions, the technology developed by JINHAI during its long experience, counter-tend compared to the easy market choices dedicated to the production in series, can fit the most exigent needs of the customers.<br \/>\nReplacement screws and barrels from JINHAI increase the quality and the output of any extruder. JINHAI has outstanding experience in the design and development of plasticizing units, which are applied to our own range of machines as well as to replacement units (cylindrical or conical) for twin-screw extruders of all types on the market.<br \/>\nAt an early stage JINHAI focused on it\u2018s development activities on corrosion-proof plasticizing designs of barrels, liners and screws, enabling solving problems optimal and guaranteeing a long service life. The manufacturing of more than 20.000 screws and barrels &#8211; in a wide variety of sizes and versions &#8211; has led to an extensive know-how in development and manufacturing. Thus manufacturing of units designed to optimally meet the processing needs of the customer and providing the highest possible reliability and quality.<br \/>\nd or coated, cylindrical or conical, with variable pitch or core progression, with shear, mixing or kneading zones &#8211; whatever the process technologists engineers require, JINHAI will manufacture.<\/p>\n<p><img class=\"alignnone size-full wp-image-382\" src=\"https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application.jpg\" alt=\"\" width=\"1000\" height=\"218\" srcset=\"https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-200x44.jpg 200w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-300x65.jpg 300w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-400x87.jpg 400w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-600x131.jpg 600w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-768x167.jpg 768w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application-800x174.jpg 800w, https:\/\/www.screwbarrels.com\/en\/wp-content\/uploads\/2020\/11\/application.jpg 1000w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<p>All parts are manufactured to JINHAI original drawings, customer drawings or individual design for all extruder models from JINHAI and other leading manufacturers worldwide.<\/p>\n<p>Twin-screw barrels are predominantly manufactured using CNC machines.
