What’s the advantage of die casting?
For big volume production die cast products are cheaper with uniform quality comparing to other hardware machining methods. Because die casting is semi or fully automated process which reduces much labour cost and labour mistakes.
Complex shape and structure parts can be easily cast.
The molten aluminum cools rapidly in the die, which makes the casting part produce fine-grained hard skin, so the cast parts will have strong strength.
Die cast pasts need little follow up process.
Die cast parts have highly accurate dimension and smooth surface.
Die casting parts of aluminum and zinc have features as follow:
Good corrosion resistance
High strength and hardness
High thermal conductivity
Good surface finish
