FAQ Section
What is the difference between ADC12 and A380?
ADC12 and A380 are both popular aluminium die casting alloys. ADC12 offers good fluidity and corrosion resistance, making it suitable for general purpose components. A380, on the other hand, provides better mechanical strength and toughness, often preferred for automotive and high-stress applications.
Can you do thin-wall die casting below 1.5 mm?
Yes, we specialise in thin wall aluminium casting and can produce parts with wall thicknesses below 1.5 mm, depending on the design and material. Our advanced high-pressure die casting machines ensure precision even at thin sections.
Do you provide low-volume production?
Absolutely. We support flexible order quantities starting from 500 to 1000 pieces, ideal for prototyping, pilot runs, or small batch productions, without compromising on quality.
What file formats do you accept?
We accept all standard 3D CAD formats including STEP, IGES, Pro/E, and SolidWorks files, making it easy for you to send your designs and get quick feedback on manufacturability.
