The 3D sand printing (3DSP), by binder jetting technology for rapid casting, has a pivotal role in promoting the development of traditional casting industry as result producing high-quality and economical molds. This work presents an approach monitoring analyzing powder sand-bed images to serve realtime control system 3DSP machine. A deep residual network (ResNet) is used classify defects occur...

New Nissan to feature complex aluminum castings The new Nissan GT-R features aluminum inner-door and rear-seat structures made from Alcoa’s proprietary vacuum die casting process (AVDC) at the company’s plant in Soest, Germany. Both components also feature new proprietary alloys developed by Alcoa. The new C-446 alloy, in combination with the unique advantages of the AVDC process, enabled Alcoa...

Monitoring and control of manufacturing processes is an essential part of any industry. Being able to collect sensor measurements, analyse the measurements in an intelligent way, select appropriate actions and validate the desired results of these actions is a tremendous goal to be achieved. In this paper, we propose a monitoring and control framework of a multi-tier closedloop controlling lost...

Pyrolysis-gas chromatography-mass spectrometry (MS) was used to identify the major organic products produced by pyrolysis of three foundry sand resins: (i) Novolac and (ii) phenolic urethane (PU) (both phenol-formaldehyde based resins) and (iii) furan (furfuryl alcohol based resin). These resins are used in the metal casting industry as a "sand binder" for making cores (used to produce cavities...

Article history: Received:29.09.2013. Received in revised form: 17.12.2013. Accepted: 24.12.2013. A three-dimensional Computer Aided Design (CAD) model of the bearing sleeve casting is established by Pro/E software. The ViewCast program is utilized for studying casting processes of solidification and mould-filling in order to optimize the casting technology. Based on the solidification simulati...

In a foundry casting line, contaminants are released from a large area. Casting fumes include both volatile and particulate compounds. The volatile fraction contains hydrocarbons, whereas the particulate fraction mostly comprises a mixture of vaporized metal fumes. Casting fumes lower the air quality in foundries. The design of local ventilation for the casting area is a challenging task, becau...

Although the role of dental casting alloys has changed in recent years with the development of improved all-ceramic materials and resin-based composites, alloys will likely continue to be critical assets in the treatment of missing and severely damaged teeth. Alloy shave physical, chemical, and biologic properties that exceed other classes of materials. The selection of the appropriate dental c...

A hierarchical representation formed by an octree for a volume ray casting is a well-known data structure to skip over transparent regions requiring little preprocessing and storage. However, it accompanies unnecessary comparison and level shift between octants. We propose a new data structure named half-skewed octree, which is an auxiliary octree to support the conventional octree. In preproce...

Production of overall CO2 emissions has exhibited a significant reduction in almost every industry the last decades. The steelmaking is still one most producers worldwide. processes and facilities used at steel plants, such as blast furnace electric arc furnace, generate large amount waste heat, which can be recovered meaningfully used. Another way to reduce number low-quality products which, d...
