New Approach to Aluminium-Polymer Alloys
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
New approach to aluminium-polymer alloys prepared by in-situ mixing or addition of molten metal onto polymer granules will be highlighted. This concept is simple and never been attempted before due to the thermal instability ...
Comparative Study on Mechanical Properties and Microstructure of Binary Aluminium Alloy using Sand and Green Sand Molds
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
Products of binary system especially for aluminium alloys and others binary are of great use.However, mechanical properties of these products are still low because of wrongly chosen the types of molds. Therefore,it is ...
Study on Influence of Silicon Percentage on Flowability of Binary Aluminium-Silicon Alloy
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
Study on flowability of liquid of binary aluminium-silicon with the difference percentage of silicon is carried out by using CO2 mold and with the spiral pattern. The result showed that flowability of molten metal of ...
Acrylic Pattern for Sand Mould
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
Patterns used in casting process may be made of wood, metal, plastics or other materials. Pattern are fabricated to obtain good standards of product, so that they can last for a period of time, depending to the quality ...
Role of clay (Bentonite) on mold making process in foundry metallurgy
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
The foundry engineer is usually familiar with the fact that there are different types of clay,such as kaolinite and montmorillonite (bentonite). The bonding action of kaolinite in moulding sands results from the free ionic ...
The application of Fluidity Spiral in sand-mold casting
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
The term fluidity is always used in the cast-metals industry. Fluidity is the reciprocal of viscosity. The foundryman job is to search the amount of quantity that will permit him to evaluate the relative ability of a given ...
Effects of magnesium sulfate attack on ordinary portland cement (OPC) mortars
(Portuguese Electrochemical Society, 2008)
The chemical and mineralogical compositions in Ordinary Portland Cement (OPC) were
determined and cement which is low of C3A is more easily exposed to sulfate environment. The relation between physical strength of mortars ...
Properties of Zinc alloy cast product with different composition of Silica Sand and Bentonite in Green Sand Mould
(Universiti Malaysia Perlis, 2009-12-01)
This project is to produce tertiary alloy of Zinc-Aluminium-Magnesium (Zn-3Al-2Mg) with different composition of bentonite and silica sand in the green sand mould. Zn alloy casting industry using green sand molding is ...
