We are now ISO 9001:2008 certified. Induction bending (also known as hot bending and sometimes as hot rolling) happens when heat is applied to a specific area of a metal tube or steel pipe, usually with the use of an induction coil, in order to make the material easier to bend to a preset radius.
Variable costs are corporate expenses that vary in direct proportion to the quantity of output.Unlike fixed costs, which remain constant regardless of output, variable costs are a direct function of production volume, rising whenever production expands and falling whenever it contracts.ariable costs are corporate expenses that vary in direct proportion to the quantity of output.
All the costs faced by companies can be broken into two main categories: fixed costs and variable costs. Fixed costs are costs that are independent of output. These remain constant throughout the relevant range and are usually considered sunk for the relevant range (not relevant to output decisions).Fixed costs often include rent, buildings, machinery, etc.Variable costs are costs that vary with output.Generally variable costs increase at a constant rate relative to labor and capital. Variable costs may include wages, utilities, materials used in production, etc. In accounting they also often refer to mixed costs.ixed costs are costs that are independent of output.
