Much of the wax used in investment casting can be reclaimed and reused. [2] Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process. Investment casting is so named because the process invests (surrounds) the pattern with refractory material to make a mould, and a molten substance is cast into the ...
Lost-wax casting – also called investment casting, precision casting, or cire perdue (French: [siʁ pɛʁdy]; borrowed from French) [1] – is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.
In the Austrian Business Cycle Theory and all its different frameworks, the actual definition of malinvestment is the same: an investment with high potential that loses value. [2] A malinvestment only occurs if the loss in value is due to increased interest rates. [3]
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
The Kuznets swing (or Kuznets cycle) is a claimed medium-range economic wave with a period of 15–25 years identified in 1930 by Simon Kuznets. [1] Kuznets connected these waves with demographic processes, in particular with immigrant inflows/outflows and the changes in construction intensity that they caused, that is why he denoted them as "demographic" or "building" cycles/swings.
Investment is often modeled as a function of interest rates, given by the relation I = I (r), with the interest rate negatively affecting investment because it is the cost of acquiring funds with which to purchase investment goods, and with income positively affecting investment because higher income signals greater opportunities to sell the ...
Evaporative-pattern casting is a type of casting process that uses a pattern made from a material that will evaporate when the molten metal is poured into the molding cavity. The most common evaporative-pattern material used is polystyrene foam. [1] The two major evaporative-pattern casting processes are: [1] Lost-foam casting; Full-mold casting
Some sources argue identifying any such patterns as a "cycle" is a misnomer, because of their non-cyclical nature. [1] Economists using efficient-market hypothesis say that asset prices reflect all available information meaning that it is impossible to systematically beat the market by taking advantage of such cycles.
