ABSTRACT:
Shipping container carrying cargoes requiring temperature control and/or ventilation require a main frame capable of housing a refrigeration unit. Hitherto, main frames have been constructed by welding the component parts together which is extremely time consuming. The present invention provides a method for producing a main frame in which a recessed portion for housing the refrigeration unit is deep drawn while a force is simultaneously applied to maintain a substantially constant thickness of the main frame.
