Dedy Krisbianto, Dwi Rahmalina, Agri Suwandi

Abstract


Untuk mendapatkan hasil akhir produk yang baik pada proses produksi die casting cold chamber dengan bahan material aluminium ADC12 yang sering dihadapi untuk proses akhir proses produksi die casting antara lain  porosity , sebelum pembuatan produk perlu dilakukan simulasi desain produk. Modifikasi  desain produk dapat memakai program Solidworks baik untuk desain simulasi 3D, manfaat simulasi desain produk untuk mengetahui secara dini hasil produk yang akan dibuat, yang perlu diperhatikan adalah desain gate runner pada die casting karena dapat mengetahui kecepatan aliran logam ke desain produk, untuk mengatuhui aliran cairan logam yang masuk ke dies, bisa melakukan simulasi dengan memakai program simulasi MAGMASOFT dapat mendeteksi cacat produk akhir tanpa melakukan try and error manual.Diperlukan  parameter yang dilakukan, slow shot, A 0.4, B 0.5 m/s, fast shot, A3.5, B 3.5 m/s, temperatur Molten, 670, B 670 ◦c, cycle time, A 55, B 55 detik, diameter biskuit, A85, B 90 mm. Dalam  desain modifikasi gating system A dari hasil X-Ray porosity pada produk mencapai 12.18% sedangkan pada desain modifikasi B menunjukan  penurunan cacat porosity mencapai 3.17% sehingga desain B dapat direkomendasikan untuk produk masal.
