Microshrinkages are known as probably the most difficult defects to avoid in high-precision foundry. The presence of this failure renders the casting invalid, with the subsequent cost increment. Modelling the foundry process as an expert knowledge cloud allows properly-trained machine learning algorithms to foresee the value of a certain variable, in this case the probability that a microshrink...

Casting production has environmental implications that extend beyond the foundry’s premises. By taking a life-cycle approach the impacts upstream (supply side) and downstream (customer/user side) can be identified. The benefits of a foundry’s actions to reduce an environmental impact might be leveraged to reduce impacts at other stages in the life-cycle. However, as a minor player in the supply...

In this paper, we represent a method for machine learning to predict the defect in foundry operation. Foundry has become driving tool produce part another industry like automobile, marine, and weapon. These processes mainly have two critical problems decrease quality assurance. Now, increase of The process’s failure is associated with micro shrinkage ultimate tensile strength. We process by uti...

This paper discusses the initial efforts to implement simulation modeling as a visual management and analysis tool at an automotive foundry plant manufacturing engine blocks. The foundry process was modeled using Pro Model to identify bottlenecks and evaluate machine performance, cycle times and production data (total parts, rejects, throughput, products/hr) essential for efficient production c...

Product data management is an engineering oriented information system. Engineering change request, engineering change notice, and engineering change control workflow in a product data management system are usually utilized starting from the detail product design phase. Lack of guidelines to identify configuration items and design change control workflow is one of the major reasons for not using...

This paper presents the progress of monolithic technology for microwave application, focusing on gallium nitride technology advances in the realization of integrated power amplifiers. Three design examples, developed for microwave backhaul radios, are shown. The first design is a 7 GHz Doherty developed with a research foundry, while the second and the third are a 7 GHz Doherty and a 7–15 GHz d...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...
