Verification of Modification Effect on Prototype Castings from GJV Using Ultrasound Checking
Journal Title: Archiwum Odlewnictwa - Year 2012, Vol 12, Issue 3
Abstract
Reason for and risks of using of cast iron with vermicular graphite for typical construction parts. Ultrasound checking of graphite shape. Factors influencing plausibility of result. Difference between laboratory and operation application. Roughness, parallelism, stability and size dimension of walls. Conditions, proposals for simplification and productivity enhancement of castings checking. Recommendation.

Safety management system of subcontractors’ works in foundry companies
Most companies use the services of subcontractors, either in their core business, or to support the work – e.g. maintenance. This poses the need for effective and systematic monitoring of the work of subcontractors, espe...
Evolution of Mg-5Al-0.4Mn microstructure after rare earth elements addition
Mg-5Al-0.4Mn-xRE (x = 0, 1, 2, 3 wt.%) magnesium alloys were prepared successfully by casting method. The microstructure was investigated by light microscopy. The influence of rare earth (RE) elements on the area fractio...
The geometrical precision of the silicone matrices to the manufacturing of the models of the gear
The article presents the researches of geometrical precision of silicone casting form manufactured with using of the process of rapid prototyping of the tools (RT – Rapid Tooling). The testing casting form is applied to...
Quality stabilisation of synthetic sand containing bentonite in process lines
Stabilisation of sand quality requires the monitoring and control of sand moisture contents and its other parameters at each stage of sand processing, i.e. during the preparation of return sand mix and rebonding processe...
Identification of temperature changes dynamics in selected castings as a contribution to performance life improvement
Parameters describing boundary conditions and dynamics of temperature changes during casting cooling in foundry moulds and the successive performance, especially as regards the massive cast elements, were discussed. Cons...
