Die Casting FAQ
How do I determine which die casting machine tonnage my part requires?
Machine tonnage requirements depend on your part’s projected surface area (the 2D silhouette of the part perpendicular to mold opening direction). As a rough guide, parts under 150mm typically fit our 135T-250T machines, parts 150-350mm use 250T-420T machines, and large components above 350mm require our 900T machine.
Our mold engineering team calculates precise tonnage requirements during quoting based on your CAD files and projection area.
What's the difference between ADC-12 / A360 and ADC-3 / A383 aluminum alloys, and which should I specify?
ADC-12 / A360 (equivalent to ADC-3 / A383) offers excellent castability and represents 82% of our production, ideal for pneumatic tools, agricultural machinery, and LED lighting where corrosion resistance is secondary. It is the most commonly use material for die casting.
ADC-3 / A383 (ADC-12 / A360) provides enhanced corrosion resistance for marine components, boat hardware, and outdoor applications exposed to saltwater or harsh environments, though it costs approximately 15-20% more than ADC-12 / A360 and has lower fluidity than ADC-12 / A360.
What's your minimum order quantity for die cast aluminum parts?
MOQ depends on part complexity and size. Simple single-cavity parts from our 135T-420T machines have 2,000-piece minimums, while complex multi-cavity molds or large castings from our 900T machine require 1,000 piece minimums to justify tooling investment.
How do you control porosity in critical structural areas of die castings?
Our mold flow simulation identifies potential porosity locations during mold design, allowing strategic gate placement and venting to direct porosity away from critical areas. Vacuum-assisted casting and optimized injection parameters minimize gas entrapment.
For medical equipment components or pneumatic tool pressure chambers requiring zero porosity, we specify X-ray inspection or proof pressure testing as additional verification.
What wall thickness limitations should I design for in aluminum die castings?
Minimum wall thickness is typically 2.5-4.5mm depending on part size and flow length. Walls below 1.5mm risk incomplete fill or weak sections.
Maximum wall thickness should generally not exceed 10mm due to shrinkage and porosity concerns in heavy sections. Our mold engineering team provides DFM feedback during quoting if your design includes problematic wall thickness variations.
What surface finish can I expect directly from the die casting process?
As-cast aluminum surfaces typically achieve Ra 3.2-6.3 μm depending on mold condition and part geometry. This requires polishing or shot blasting before surface coating for most applications. Cosmetic surfaces visible to end users need secondary finishing operations.
Mold texturing can create specific surface patterns, but fine surface finish requires post-casting polishing at our facility.
What quality checks happen during die casting before parts move to CNC machining?
Operators perform visual inspection for surface defects, flash, and incomplete fill on every casting. Dimensional spot checks using go/no-go gauges verify critical features at defined intervals.
Our quality team conducts periodic weight checks to confirm consistent cavity fill and samples parts for CMM verification. Defective castings are scrapped immediately rather than proceeding to expensive CNC machining operations.
