SINAR AGUNG SELALU SUKSES KARANGANYAR JAWA TENGAH). Skripsi, Fakultas Keguruan dan Ilmu Pendidikan Universitas Sebelas Maret Surakarta. Juli 2013. Tujuan penelitian ini adalah untuk mengetahui: (1) pengaruh parameter melt temperature terhadap kualitas produk injection molding yang dihasilkan. (2) parameter melt temperature yang menghasilkan produk dengan kualitas terbaik pada proses injection molding produk plastik Polypropylene (PP) menggunakan software simulasi. (3) kesesuaian antara software simulasi dengan aplikasi produksi di industri untuk desain parameter kerja melt temperature pada proses injection molding produk plastik Polypropylene (PP). Penelitian ini dilakukan dengan analisis kualitas produk injection molding (Spion PS 135). Analisis produk dengan simulasi menggunakan software Autodesk Inventor 2013. Parameter kerja injection molding digunakan adalah mold temperature 50°C, maximum machine injection pressure 85 MPa, injection time 2 s, clamp open machine time 7 s, dengan memvariasikan parameter melt temperature yaitu 200°C, 210°C, 220°C, 230°C, 240°C, 250°C, 260°C, 270°C dan 280°C, 290°C. Beberapa variasi parameter melt temperature dieksekusi menggunakan mesin injection molding Haitian HTF 160X. Data hasil penelitian dianalisis menggunakan teknik analisis deskriptif. Data dan analisis hasil penelitian menunjukkan parameter melt temperature mempengaruhi total part weight, quality prediction, cacat shrinkage dan sink mark produk Spion PS 135. Peningkatan melt temperature menyebabkan penurunan total part weight. Quality prediction terbaik produk Spion PS 135 adalah pada parameter melt temperature 210s/d280°C, mold temperature 50°C, maximum machine injection pressure 85 MPa, injection time 2 s, clamp open machine time 7 s, dengan kualitas terbaik pada nilai melt temperature 210°C dan 220°C. Analisis secara visual produk, menggunakan software Autodesk Inventor 2013, sesuai dengan hasil eksekusi menggunakan mesin injection molding dari PT.SASS Karanganyar.

ANALYSIS OF REARVIEW MIRROR CASE PRODUCT OF PS 135 BY THE REGULATION OF MELT TEMPERATURE PARAMETER OF THE POLYPROPYLENE (PP) PLASTIC MATERIAL ON INJECTION MOLDING PROCESS (A CASE STUDY AT THE LIMITED LIABILITY COMPANY OF PT.SINAR AGUNG SELALU SUKSES, KARANGANYAR, CENTRAL JAVA) Skripsi: the Faculty of Teacher Training and Education, Sebalas Maret University, July 2013) The objectives of this research are to investigate: (1) the effect of melt temperature parameter on the quality product resulting from the injection molding, (2) the melt temperature parameter resulting in the best rearview mirror case on the injection molding process of polypropylene (PP) plastic product by using the simulation software, and (3) the correspondence between the simulation software and the production application in industry for the work parameter design of melt temperature on the injection molding process of polypropylene (PP) plastic product. This research was conducted by analyzing the quality product injection molding of the rearview mirror case product of PS 135. The analysis with simulation used the software of Autodesk Inventor 2013. The work parameter of the injection molding included the mold temperature of 50°C, the maximum machine injection pressure of 85 MPa, the injection time of 2 s, and the clamp open machine time of 7 s, with the variations of melt temperature of 200°C, 210°C, 220°C, 230°C, 240°C, 250°C, 260°C, 270°C, 280°C, and 290°C. The variations of melt temperature were executed by using the injection molding machine of Haitian HTF 160X. The data of the research were analyzed by using the descriptive technique of analysis. The result of the research shows that the melt temperature parameter influence the total part weight, quality prediction, shrinkage defect, and sink mark defect of the rearview mirror case product of PS 135. The increase in the melt temperature causes the decrease in the total part weight. The best quality prediction of the rearview mirror case product of PS 135 result from parameter of the melt temperatures ranging 210°s/d280°C, the mold temperature of 50°C, the maximum machine injection pressure of 85 MPa, the injection time of 2 s, and the clamp open machine time of 7 s with the best quality of the product at melt temperature of 210°C and 220°C. The visual analysis on the rearview mirror case product used the software of Autodesk Inventor 2013 has a correspondence with the execution of the injection molding machine at the limited liability company of PT.Sinar Agung Selalu Sukses, Karanganyar.
