Abstract

Sendi pinggul dapat mengalami kerusakan karena faktor usia, umur, maupun penyakit. Untuk mengobatinya dilakukan pemasangan artificial hip joint (AHP). Investment casting adalah metode yang banyak digunakan untuk manufaktur AHP, karena memiliki hasil finishing yang presisi. Untuk mencari parameter pengecoran yang optimum diperlukan permodelan dengan metode elemen hingga. Dengan dilakukan permodelan terlebih dahulu diharapkan saat tahap produksi sudah didapatkan parameter yang optimal. Pada penelitian ini dilakukan permodelan pengecoran dengan variasi ketebalan cetakan yaitu 6, 7, 8, 9, 10, dan 11 mm serta gating system single gate dan multiple gate. Dari variasi tersebut dianalisis distribusi temperatur, fluiditas, proses solidifikasi, dan shrinkage yang optimal. Didapatkan parameter optimal pada variasi ketebalan cetakan 11 mm dan desain gating system multi gate. ==================================================================================================== Hip joint could suffer damages due to several factors, like age, accident, and disease. Artificial hip joint is one of the way to treat the disease. Investment casting is a method that numerously used to cast AHP, because of its superior precise finishing. To find the optimum parameter, simulation using finite element method is done. By simulate the investment casting first, it expected to find the optimum parameters obtained for production phase. In this research, casting modelling with variation consists of shell thickness with 6, 7, 8, 9, 10, and 11 mm and gating system design with single and multiple gate are conducted. From the variation, it expected to obtain optimum temperature distribution, fluidity, solidification process, and defect formation. The optimum result is in 11 mm mold thickness variation and multi gate gating system design.
