Die-casting cost calculation: (water and electricity cost for each component+labor cost+material cost) x number of components+hole drilling cost+equipment wear cost.
If you don't choose die casting, then you have to choose CNC for machining.
Processing cost calculation: (utilities+labor+material cost of each component) x number of components+equipment wear cost.
Die casting production: saving raw materials, high efficiency, suitable for mass production.
Machining production: accurate size, smooth surface of parts, but slow speed, serious waste of raw materials.
If the number of products exceeds 1.5 million, you can consider opening the mold, but it depends on the size of the machine. However, there may be some difficulties in developing molds and producing such products, so the cost of die casting should increase a little/
