PLANNING FOR MASS PRODUCTION

Henry Ford - the father of mass production

An early Ford vehicle

     

Planning the production of your possible design is an important aspect of the design process and will show the examiner that you have considered how your solution will be made on a mass production line, with a labour force. A mass production line is a method of making thousands of your final solution in a factory. The labour force is the people/workers who will put it together. At the beginning of the century the first mass production line was set up in the USA. The Ford Motor Company set up a ‘line’ of workers who put together each car. The line was composed of hundreds of people each doing only one job. When you plan your production line you need to keep each stage of manufacture very simple. This is planning for ‘mass production’.

     
A Simple Production Line for the Assembly of a Clock Face and Mechanism

FLOW CHART OF PRODUCTION/ASSEMBLY LINE

     
1. The plastic face is cut to shape on a band saw or jig saw. Waste plastic placed in recycle bin - one person required, time - four minutes.
2. The edges of the face are smoothed first on a sanding disc and then on a polishing machine - two people required, overall time - ten minutes.
3. The face is set up on a drilling machine and the centre is drilled at 16mm diameter in order that the clock spindle will pass through - one person required, time - 4 minutes.
4. The numbers are set up accurately on the face using a jig to align numbers precisely - one person required, time - 8 minutes.
5. The mechanism is set up and hands are attached and fixed in position - one person, time - 2 minutes.
6. Battery placed in position and tested - same person as for stage 5, time - 1 minute.
7. Time set - one person - same as for previous two stages, time 1 minute.
8. Quality control check. Each clock checked rigorously for quality of finish and working order - one person, time - 3 minutes.

Total - 7 people.
Time - 33 minutes.
