How to calculate your cost of changeover time or downtime of your machine

To calculate the costs of downtime of your machinery at the customer (this happens when you have a changeover)
With Spanclamps you will be able to convince your customer to select your machinery as you will reduce downtime.

The calculation of the costs of downtime:

1) lost labour costs = the duration of the machine downtime x the hourly pay rate of your operators

2) products costs = the price of a single unit product x the total of items you produce in a certain period x the machine downtime period

3) recovery costs = work out how much it costs you for machine reboots, energy surges, replacing and repairing parts, retrieving lost data + your other calculstions to get a more accurate machine downtime vlaue

4) extra costs = simply bear in mind that the value of machine downtime goes beyond profits lost during the downtown period

5) total costs = all the above costs + total cost of a machine downtime



- start using spanclamps or turnlocks to reduce your changeover time of a machine

         - most common technical fault is overheating of particular parts

         - vibrations is a sign a machine is breaking

         - wear and tear

         - operator misuse
