Abstract

Kemasan kosmetik berbentuk silinder umumnya menggunakan material polipropilena (PP) dengan variasi ketebalan 1, 2, 3, dan 4 mm serta berbagai pilihan warna. Konsistensi warna kemasan perlu dikendalikan melalui pembandingan dengan color chip sebagai standar acuan yang memiliki karakteristik ketebalan dan warna yang sesuai dengan produk. Studi ini bertujuan merancang dan membuat purwarupa cetakan color chip untuk menghasilkan spesimen dengan ketebalan 1, 2, 3, dan 4 mm serta kompatibel dengan mesin injection molding Hwa Chin 80SE. Perancangan cetakan dilakukan dengan mempertimbangkan konfigurasi komponen pembentuk spesimen, sistem pendingin, sistem penyelarasan, dan sistem ejeksi. Komponen insert core dan cavity core dibuat dari baja NAK80, sedangkan insert plate, cavity plate, insert clamping, dan cavity clamping dibuat dari baja S50C. Sistem pendingin menggunakan tiga saluran berdiameter 6 mm yang masing-masing terdiri atas dua saluran pada insert plate dan satu saluran pada cavity plate. Pengujian dilakukan dengan menginjeksikan material PP ke dalam rongga cetakan dan mendinginkannya melalui sistem pendingin yang dirancang. Hasil pengujian menunjukkan bahwa purwarupa cetakan mampu menghasilkan sepasang spesimen color chip dalam satu siklus pencetakan, dengan setiap spesimen memiliki ketebalan bertingkat 1, 2, 3, dan 4 mm sesuai dengan rancangan. Waktu siklus pencetakan yang diperoleh adalah 13 detik. Hasil tersebut menunjukkan bahwa purwarupa cetakan yang dikembangkan mampu menghasilkan spesimen color chip dengan konfigurasi ketebalan yang diperlukan dan berpotensi digunakan sebagai standar acuan untuk mendukung pengendalian serta evaluasi konsistensi warna kemasan kosmetik berbahan PP.
