SUMMARY

Die casting is a cost-effective method for producing small metal components, primarily due to its low running costs despite high initial equipment investments. While die casting minimizes the need for extensive post-processing, many parts still require additional machining, such as drilling or planing, to achieve precision. For those considering alternatives, RepRap 3D printing, specifically the Mendel model, offers a viable option for producing plastic components, though initial costs for a complete kit are around $1,000. Mastery of design software like TurboCad can enhance the efficiency of both die casting and 3D printing processes.

PREREQUISITES
  • Understanding of die casting processes and equipment
  • Familiarity with machining techniques such as drilling and planing
  • Knowledge of 3D printing technologies, specifically RepRap systems
  • Proficiency in design software, particularly TurboCad
NEXT STEPS
  • Research the cost-benefit analysis of die casting versus traditional machining methods
  • Explore advanced techniques in die casting for improved precision
  • Learn about the capabilities and limitations of RepRap 3D printing
  • Investigate TurboCad tutorials to enhance design skills for manufacturing
USEFUL FOR

This discussion is beneficial for manufacturing engineers, product designers, and hobbyists interested in cost-effective production methods for small metal and plastic components.

I know that the initial outlay for automated equipment is quite high etc but the running cost is relatively low isn't it? Is it right to say thatf for smaller metal components die casting is favoured as not much further work is required to the work piece

Die casting can be efficient, but bear in mind that many die cast parts need to be drilled, planed, or otherwise machined before they can be used.

The casting helps remove the cost of creating the part from scratch, but if the part has to be used in an application that requires some precision, it will have to be machined to fit.
 
Depending upon the desired end product, I might also suggest that you look into RepRap 3D printing in plastic. Unfortunately, it still costs about $1,000 to buy a full kit (mechanical and plastic parts), but it can soon pay for itself if you need to make a fair bit of stuff. I'm planning to get one, probably a Mendel, after I figure out how to use my new TurboCad program. (At least it will save the hassle of hand-filing new parts every time I blow the guts out of a silencer. :biggrin:)
