Abstract

Polypropylene (PP) is a crystalline thermoplastic widely used in many industrial applications such as medical devices, automotive parts, battery cases, household products, or packaging trays due to its high chemical resistance, processability and impact/stiffness balance, well barrier property, lightness and toughness respectively. However, researchers and engineers have focused on new injection methods to reduce the cost of products and production time. After doing a literature survey about the new injection methods in this study, the co-injection simulation conducted with the Moldex 3-D program using properties of both virgin PP and scrap PP. By the way, the effect of co-injection parameters such as injection pressure, closing force, mod and melt temperatures on co-injection filling characterization investigated. As a result that when the core temperature of the first injected virgin PP is higher than its nucleation temperature, the core of the wall goes on the wall with the second injection of scrap PP until cooling of nucleation temperature. End of co-injection, the second injected scrap PP after first injected virgin PP replaced the advancing virgin PP on the wall core, and a three-layered wall consisting of original PP, scrap PP, original PP obtained.

Polipropilen ambalajın eş-enjeksiyon dolum karakteristiğinin 3-B simülasyonu

Abstract

Polipropilen (PP), hafiflik ve tokluk, yüksek kimyasal dayanım, şekillendirilebilirlik, darbe ve rijitliği dengelenmiş iyi bariyer özelliklerinden dolayı medikal ve otomotiv parçaları, ev eşyaları ve gıda ambalajlarının imalatında yaygın kullanılan kristalin termoplastik malzemedir. Bu bağlamda, araştırmacılar ve mühendisler üretim zamanı ve ürün maliyetini azaltmak için yeni enjeksiyon metotları üzerine yoğunlaşmışlardır. Bu çalışmada yeni enjeksiyon metotlarıyla ilgili literatür araştırmasından sonra, üretim hurdası PP ve orijinal PP’ nin özellikleri kullanılarak 3-B Moldex programıyla eş enjeksiyon simülasyonlar gerçekleştirilmiştir. Böylece, enjeksiyon zamanı, enjeksiyon basıncı, kapama kuvveti, kalıp ve enjeksiyon sıcaklığı gibi eş-enjeksiyon parametrelerinin dolum karakteristiğine etkisi araştırılmaya çalışılmıştır. İlk enjekte edilen orijinal PP’ nin yolluk merkezindeki sıcaklığı çekirdeklenme sıcaklığından yüksek olduğunda, eş zamanlı ikinci enjekte edilen üretim hurdası PP’nin orijinal PP katılaşana kadar yolukta ilerlemekte olduğu sonucuna varılmıştır. Eş-enjeksiyon simülasyon sonunda, ilk enjekte edilen ve ilerleyen orijinal PP’ nin yerini ikinci enjekte edilen üretim hurdası PP almış ve orijinal PP, hurda PP, orijinal PP’ den oluşan üç katmalı cidar elde edilmiştir.
