Dari serangkaian ujicoba mulai dari menentukan tooling (tip &die) dengan cara melakukan perhitungan Draw Down Rasio (DDR)& Draw Ratio Balance (DRB), mencoba Line speed extruder sampai ujicoba temperatur Extruder pada projek Telkom ADSS untuk menentukan hasil kualitas hasil pengujian yang terbaik sudah dilakukan, tiga buah variable yang berpengaruh terhadap kualitas hasil tes plastik telah di pilih yaitu: perhitungan DDR & DRB untuk menentukan tooling yang gunakan dan temperatur extruder. Rangkaian pengujian dilakukan dengan tujuan mempelajari seberapa besar pengaruh tooling (tip & die) dan juga temperatur extruder. Hasil pengujian terbaik yang tidak menyebabkan cacat pada permukaan kabel yaitu dengan menggunakan tooling tip berdiameter 8.2 mm dan die berdiameter 13.5 dan temperatur screwextruder Z1=130°C, Z2=160°C, Z3=165°C, Z4=170°C, Z5=175°C, dan pada zona crosshead H1=180°C, H2=180°C, H3=185°C, H4=185°C. Dari ketiga variabel tersebut tololing (tip & die), line speed dan temperature extruder adalah sangat signifikan.Karena keduanya sangat bersinggunganDownloads
