Alan Beckwith Macbro produces all grades of resin-coated sands for shell core and shell moulding. We manufacture using solid resin and hot coating technology which results in a product that has significant advantages over liquid and other solid resin processes in the areas of OH&S, cost, environmental factors and quality.
Applications
Hot coated resin sands can be used for all types of core and shell moulds.
Grades
- A range of resin strengths can be manufactured, from 1.5% to 5.0%
- Silica, Zircon and Chromite Sands can all be coated, or blends of the different sands can be produced, such as 50% zircon 50% silica.
- Sands of different AFS can be coated, typically 50 to 90 AFS are used.
- Other additives can be added to improve operator comfort.
Benefits
- Quicker build up and faster curing times give quicker cycle times and improvements in productivity.
- Less resin is required to attain the same strengths, which results in less fuming and emissions during manufacturing and casting.
- Lower overall cost.
Alan Beckwith Macbro produces a resin coated sand from thermally reclaimed sand. The reclaimed sand exhibits unique properties due to the changes that the sand grains have undergone during reclaiming.
