All TS251 students are supplied with a "Monolynx" microscope, as part of their home kits, (It was demonstrated in programme 4). This film takes the microscope as an example of multimater...ial manufacture, and examines the problems and decisions in choosing the "right" materials for the job. Dr. Nick Reid (O.U.) goes to the factories where the base is die cast in aluminium, where the eye pieces are injection moulded in plastics, and where the final assembly and inspection are carried out. The processes are all covered in vision and supplementary information is given.

Footage description: Shots of OU technology kit incidence light microscope being assembled. Nick Reid introduces the programme. It will examine the way the microscope was made and how the choice of materials used for construction was made. Shot of the microscope cut in half. Reid points out its components. Reid with a prototype of the above microscope. Shot of design office showing designers and draughtsman at work on microscope design. Reid explains the differences between the prototype and production model of the microscope. Ed Dickson explains the process by which instructions are turned into dies for casting a finished product. Gravity die casting method for casting a microscope body examined. Shots of the process. Commentary tells why gravity die casting rather than some other die casting method was used. Ed Dickson explains what materials were used to make the die and also how it was made. Shots of microscope bodies being manufactured by the gravity die casting method. Alf Muggeridge discusses the costing involved in producing microscope bodies. Shots of cast microscope bodies being machined. Commentary explains each step of the way. Shots of glass lenses for microscope being ground. D. Crawford-Taylor explains what plastic components his company make for the microscope. He discusses the advantages of plastics over other materials. Crawford-Taylor explains why ? was used for the microscope rather than some other type of plastic. He then tells what materials the moulds for the injection moulding process were made of. Shots of the process in progress. Crawford-Taylor explains what other parts of the microscope could be made from plastics. He also lists some of the drawbacks of using plastics for microscope construction. Shots of final assembly of the microscope. Reid sums up the programme.
