With the growing focus on managing cost, sustainability and environmental responsibility, less waste is clearly among the many advantages of investment casting. Less waste reduces the amount and cost of alloys required for a run. It can also reduce the expense of reprocessing or disposing of excess material. Decreasing waste also advances sustainability by keeping material out of landfills and waste processing. This is made possible by investment casting’s near-net-shape process, where very little machining and waste is necessary.
