Bahan baku atau bahan umpan (feedstock) merupakan yang penting pada proses Cetakan Injeksi Logam (MIM). Pada penelitian ini, tiga dikarakterisasi untuk mengetahui jenis pengikatnya (binder). A (pabrikan Jepang), B Korea) dan C (hasil penelitian) dengan menggunakan SEM, PSA, TG-DTA, Rheometer Torque kelarutan. Karakterisasi SEM menunjukkan bentuk serbuk terdiri dari ligament, rounded, spherical,...

injection molding is one of the most important and common plastic formation methods. combination of modeling tools and optimization algorithms can be used in order to determine optimum process conditions for the injection molding of a special part. because of the complication of the injection molding process and multiplicity of parameters and their interactive effects on one another, analytical...

Micro-powder injection molding (μ-PIM) is one of the most promising processes of mass production for the fabrication of small complexly shaped ceramic or metallic parts with high sintered density. However, dimensional accuracy of finished parts is difficult to achieve because of extremely high shear rates during the injection molding process. This promotes the separation of powder and binder ev...

This paper presents measurements of acoustic emission (AE) signals during the injection molding of polypropylene with new and damaged mold. The damaged injection mold has cracks induced by laser surface heat treatment. Standard test specimens were injection molded, commonly used for examining the shrinkage behavior of various thermoplastic materials. The measured AE burst signals during injecti...
