The foundry business grows fast and, to keep up the pace, the players need to use the latest and most efficient technologies wherever available.
One good example is the useage of the most innovative technologies enabling foundries to produce highly complex sand molds and cores while still very accurate dimension wise.
This type of technology – that is using the addition of successive layers of sand – enables the foundry to make perfect shapes of very complex parts that are often difficult to produce in the common foundry molding process.
Moreover, the 3D printing technology also contributes in many cases to reduce lead time and cost that are extra incentive to consider this new technology to maintain the competitive edge in the foundry segment of the market.
Though this process is primarly suitable for R&D and prototyping projects, the new development in the production of more efficient production units are already promising to hope that one day the technology will be use on a high-scale basis.
Please have a look for yourself at the two below links to have a taste of the promising capabilities to be developed in this growing niche market.
excelent and I need more information
Please specify the extra information you need.
We have consulted one company in Kunshan, China. The cost for core making is acceptable. However the products we are going to prototype need precision machining after casting, during machining we will scrap number of castings for programing and adjustment, if we consider those castings scraped in machining, the total cost is still high. Normally the lead time for 3D prints is 7 working days, for one cavity mold is about 20 days, so we still choose one cavity mold as prototype mold.
I understant your point Jack. 3D printing core is not the solution to every requirement.
pierre, so you know understand !!~ I am a visionary not a dreamer!!!!
You are right Kevin! You are a visionary, one of a kind!
