Precision Die Cast vs Machining
There are quite a few major advantages of using precision die casting instead of machining for various components.
One of the major advantages would be the lower unit cost of parts using precision diecasting. Machining complex geometries will require the removal of a lot of the material which takes a lot of time and creates a lot of wasted material. Using precision die casting, you will be able to achieve the same result in less time and with no wasted materials. Not only that but die casting components are lighter than their machining counterparts because they require less overall material to make.
Another benefit of precision die casting is that this faster cycle time will significantly reduce the lead time for batch productions. This in turn will allow you to have a greater inventory turnover ratio.
A non-cost related benefit of precision die casting is the ability to create very consistent die castings. Because you are using a mold, the product will be very consistent every time you make it. As for machining, even the simplest movement during the process will create products that are inconsistent with each other.
One of the advantages of machining is that there is less of an upfront cost. If you are only looking for low volume production, then the unit cost savings won’t justify the investment you put in for the precision die casting tools.
