  • The production requirement for the projector is 60,000 to 80,000 units per year.
  • The design engineers at InFocus had three options for manufacturing the interface frame in magnesium --

Production Method

 Characteristics
Machining from Metal Stock Too expensive and time consuming for high volume production
Multi-part sheet metal assembly Tolerance/alignment limitations and high assembly costs
Metal Casting Tight tolerance capability and low cost, high volume production

It was obvious that a one piece precision casting would provide the best performance at a market acceptable cost for this high volume precision component
