How is injection Moulding machine hour rate calculated?

The machine hour rate is similar to the labour hour rate method and is used where the work is performed primarily on machines. If factory overhead is Rs 3, 00,000 and total machine hours are 1,500, the machine hour rate is Rs 200 per machine hour (Rs 3, 00,000 ÷ 1500 hours).

How do you calculate machine cost per hour?

Machine hour rate is obtained by dividing the total running expenses of a machine during a particular period by the number of hours the machine is estimated to work during that period.

How do you calculate machine hours?

Figuring Machine Hours Per Unit To calculate machine hours per unit, a factory must keep track of how many hours machines are run and how many units of inventory are produced. To find machine hours per unit, divide the total number of hours that machinery is operated by the number of units produced.

How do you calculate cost per machine?

Determining Basic Cost At the simplest level, a machine’s cost per hour is equal to its total cost minus its eventual salvage value divided by its total expected life. A machine that costs $25,000 and is expected to last for 17,000 hours before being sold as scrap for $1,500 would cost $1.38 per hour to use.

How do you calculate total machine hours?

For example, say a factory ran seven machines for 10 hours in one day and produced 50 widgets. Total machine hours are seven multiplied by 10 hours, or 70 hours. Machine hours per unit is calculated as 70 hours divided by 50 units, or 1.4 hours per unit.

What is tonnage in injection Moulding machine?

The “tonnage” is the measure of force that is required to keep the tool closed during the injection process. This force is the main factor in determining the injection molding machine size required for producing the part.

How do you calculate tonnage?

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton). The final figure will be the estimated amount of tons required.
