Laboratory twin screw extruder is mainly used in the research and development of polymer plastics, mainly for universities, enterprises and research institutes. The main feature is that the screw diameter is small, which greatly reduces the use of materials in the application and development.

Modular construction barrels combination, self-cleaning screw Combination. Both screws and barrels designed according to building block principle. And the machine’s extensive performance and special purpose could be achieved ideally. Independent control of barrel temperature. A variety of cutting methods that meet the requirements of various materials. Adopt good dynamic system and workmanship can bring excellent machine performance.

У параўнанні з традыцыйным двухшнековым экстрударам, трохшнековы экструдар не толькі захоўвае многія выдатныя ўласцівасці двухшнековага экструдара, але і мае наступныя характарыстыкі: 1. Лепшы эфект пластыфікацыі і змешвання: 2. Суадносіны даўжыні і дыяметра вінта кароткія, таму час знаходжання і змешвання матэрыялу большы. 3. Вышэйшая прадукцыйнасць: прадукцыйнасць трохвінтовага экструдара на 50% вышэйшая, чым у аналагічнага двухвінтовага экструдара.

Спалучайце высокую хуткасць і інтэнсіўнае змешванне двухшнековай апрацоўкі з нізкай хуткасцю, нізкай тэмпературай і нізкімі сціральнымі нагрузкамі аднашнековай апрацоўкі. Ідэальна падыходзіць для кампаундавання тэрма- і сціральна-адчувальных матэрыялаў: ПВХ-сумкі для кабеля, абуццёвых падэшваў, празрыстых кантэйнераў і медыцынскіх вырабаў; ЭВА-сумкі для бранзалеткавых кабеляў; мастэрбэчы з вугляроднай чарнілай на аснове ПЭ, ЭВА і г.д.

Кампанія «Каўін Экстружн» паспяхова стварыла высокаэфектыўны аднашнековы экструдар CSE. Такі экструдар мае значна большую прадукцыйнасць, меншы энергаспажыванне і адначасова выдатныя антыабцасныя ўласцівасці. Пры экструзіі труб спажыванне энергіі складае 0,25-0,3 кВт·г/кг, а для дошак, лістоў і грануляцыі — 0,15-0,2 кВт·г/кг, што значна ніжэй за паказчыкі звычайнага аднашнековага экструдара.

«Кавін Экстружн» — гэта спецыялізаваны вытворца і пастаўшчык паслуг па падтрымцы двухшнековых экструдараў, запчастак, дапаможнага абсталявання і комплексных вытворчых ліній.
Мы пастаўляем розныя тыпы падачы, гранулятары, абсталяванне для транспарціроўкі матэрыялаў і іншыя дапаможныя машыны для падрыхтоўкі сыравіны і далейшай перапрацоўкі.
Founded in Nanjing in 2012 by twin-screw extrusion industry veterans, Cowin Extrusion is an international, high-tech polymer processing equipment manufacturer. In September 2024, the company established Anhui COWIN in Chuzhou (near Nanjing). Alongside its affiliate, Nanjing Skr, this new 25,000-square-meter production base spans 2.33 ha and employs 80 people. Additionally, Cowin maintains a 20-person procurement, technology, and sales office in the Nanjing Jiangning Development Zone.
Cowin Extrusion focuses on R&D, manufacturing, and turnkey projects for polymer compounding equipment. Backed by a team with 20+ years of experience, the company maintains deep cooperation with domestic universities, research institutes, and leading foreign extruder companies to deliver innovative solutions.
