Selection of a rotational moulding machine is based on the following considerations
Capacity of tank which have max share in market
Monthly expected production in terms of ltr.
Range of tanks required in market (Loft, Roof, House hold, Horizontal )
Running cost of production.
The machine must be selected from the point of view that it should produce the capacity of tank most economically which have max. share in market.
Machine must be able to produce required volume of tanks which are salable in market.
And finally running cost that matters and not capital cost.
In the competitive world, running cost of production is the key to survival of a company. The
running cost depends upon the selection of the machine. If you selected the machine which is unable to control the fuel, electricity consumption. Employing
heavy maintenance and need skilled labor then such machines though are cheap but finely take away the entrepreneur towards the loss.
Therefore machine must be :-
Less power consumable
Must not be labor oriented
Maintenance free and hence interruption free
