Ultra High Molecular Weight Polyethylene (UHMWPE) has been consumed in human hip implants for the last decades. Improving the reliability of hip joint implants can reach by the understanding of wear behavior and morphology of the polyethylene. The purpose of this investigation was to determine the effect of the manufacturing process UHMWPE on the w...

Crosslinked ultra-high molecular weight polyethylene (UHMWPE) is a preferred material used as a bearing material in the artificial hip joint. The purpose of this study was to analyze the effect of dose cross-linking acetabular liner manufactured by CNC milling on wear depth. The wear test is carried out with a tribometer machine by loading the acet...

Cedera yang diakibatkan kecelakaan lalu lintas dapat menyebabkan korban menderita patah tulang, cacat tubuh, hingga kematian. Korban yang mengalami kerusakan tulang dapat disembuhkan dengan restorasi tulang, yaitu dengan menanamkan tulang buatan pada jaringan tulang yang rusak. Salah satu contoh metode implan adalah dengan membuat scaffold yang ter...

CNC milling strategy of EVA foam with varying hardness to provide a high degree of surface roughness of orthotic shoe insoles is presented in this work. Machining parameters (spindle speed, feed rate, tool path strategy, and step over) in addition to hardness material and wide tolerance insoles were optimized using a hybrid approach of Taguchi-Resp...

Along with technological developments and easy access to insight into creative entrepreneurship, many people are competing to create creative products, one of which is by utilizing laser technology. Laser cutting and engraving is used for the manufacture of engraving products in acrylic, wood, glass, leather etc. The uniqueness of the results of la...

Acr y lonitrile butadiene styrene (ABS) adalah bahan plastik yang banyak digunakan pada pembuatan komponen otomotif. Limbah ABS dari industri injection molding berupa sisa potongan runner memiliki kualitas yang baik sebagai campuran dalam siklus proses produksi. Pencampuran ini bermanfaat secara ekonomis untuk mengurangi penggunaan bahan virgin . S...

Laser machines are widely used in various types of industries, both in the manufacturing industries and in the craft/creative industries. Laser machines are often used to cut and engrave objects that have difficult material and contour properties that conventional machines cannot do. Acrylic materials are often found in the craft and creative indus...

The quality of injection moulded parts can be influenced by processing parameters. The effect of mould temperature and melt temperature on the weight and shrinkage of Styrene Acrylonitrile moulded part was observed in this research. It was found that by increasing mold temperatures at constant melt temperature and injection speed, the weight of the...

Blow molding machine is a machine that used to produced plastic bottle with injection air system to blowing the soft preform (±100 ℃ ) at 7 bar pressure of air. They are two main components in injection blowing tools i.e, injection tools to distribute the high pressure air from compressor to the bottle preform and the line sliders to make a mold ca...

Sistem kendali nominal characteristic trajectory following (NCTF) adalah sebuah sistem kendali yang terdiri dari dua buah sub sistem, yaitu nominal characteristic trajectory (NCT) dan kompensator. Pembuatan pengendali berdasarkan pada eksperimen open-loop sederhana sehingga sistem kendali NCTF sangat praktis untuk digunakaan. Arduino Uno digunakan...
