THE CHARACTERISTICS OF LAMPUNG LOCAL SAND AS CASTING SAND IN THE METAL CASTING PROCESS

Sand Mold Press Casting with Metal Pressure Control System

Sand-casting technique for trans-tibial prostheses.

A sand-casting technique for trans-tibial sockets was applied to 28 amputees, and the prosthetic fit observed through transparent check sockets. The results were better than historical reports of fittings with plaster of Paris casting by qualified prosthetists. The fit was consistently and evenly larger than the stump, but total contact could be achieved by applying three (two to five) stump so...

A Study for Analyzing Effects of Design Parameters in the Sand Casting Process of Aluminum Alloy

The use of aluminum alloys are of significant use in industry. Studying of design parameters of such products is important as not much work has been done for optimizing it. The generic formulation involves the flow, velocity, continuity fluid dynamics and shape related issues. The time for filling the mould and shape factor also play major role in performance of the casting process. In this pap...

Modeling of Reoxidation Inclusion Formation in Steel Sand Casting

A model is developed that predicts the motion and growth of oxide inclusions during pouring, as well as their final locations on the surface of steel sand castings. Inclusions originate on the melt free surface, and their subsequent growth is controlled by oxygen transfer from the atmosphere. Inclusion motion is modeled in a Lagrangian sense, taking into account drag and buoyancy forces. The in...

Costs Models in Design and Manufacturing of Sand Casting Products

In the early phases of the product life cycle, the costs controls became a major decision tool in the competitiveness of the companies due to the world competition. After defining the problems related to this control difficulties, we will present an approach using a concept of cost entity related to the design and realization activities of the product. We will try to apply this approach to the ...
