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.
DEFINITION of 'Variable Overhead Spending Variance'. The difference between actual variable overhead based on costs for indirect material involved in manufacturing, and standard variable overhead based on the budgeted costs. Variable overhead spending variance arises from difference in the costs of indirect material compared to budgeted costs. It is favorable if actual costs of indirect material â for example, paint and consumables such as oil and grease â are lower than standard variable overhead.
