Gravity Diecasting
Part 2. The Rolls-Royce Mechanised Foundry
Arrangement of Operation Stations on the Conveyor, Inspection

In this second instalment we describe the mechanised gravity diecasting foundry installed at a Rolls-Royce shadow factory. It is probably the most up-todate and efficient of its kind in the world. Considerable ingenuity is shown in the layout of the equipment around the central conveyor, but, in addition to this it will be appreciated that very skilful planning has been necessary to ensure the balanced flow of some 103 different castings in various alloys. The mere use of mechanical time-saving equipment is valueless without efficient organisation.

Considerable ingenuity is discernible in the layout of the foundry; from examination of the plan in Figure 23 it will be seen that the whole of the plant is arranged around a central conveyor that carries the castings from station to station. From the very first stage of metal melting, the work flows continuously forward until, after final heat-treatment, the castings enter the stores.

Arranged on both sides of the conveyor is the equipment for the various operations, the operators removing the castings as they arrive at the various stations and replacing them when the work is completed. Here again, skilful planning is necessary to ensure a balanced flow to each operator; this point will be appreciated when it is remembered that 103 different castings, in various alloys, are dealt with.
