Final answer:
Die casting is known for producing parts with high dimensional accuracy compared to sand casting. This is due to the molten metal being injected under high pressure into precision-made molds, a method differing from sand casting, where metal is poured into sand molds. Die casting is favored for mass production of parts that require consistent quality and detailed precision.
Step-by-step explanation:
The subject of this question is the comparison of dimensional accuracy between die casting and sand casting. Die casting is a manufacturing process where molten material, often metal, is injected into a mold under high pressure.
This process tends to produce parts with high dimensional accuracy, smooth surfaces, and thinner walls, which is superior to sand casting, where molten metal is poured into a sand mold without high pressure.
Sand casting is more tolerant of shape complexity and size, but generally results in larger tolerances and a rougher surface finish compared to die casting.
In the context of the provided information, lost-wax casting or investment casting, which is a traditional method of bronze casting, similarly involves pouring molten metal into a mold.
However, the mold is created through a wax model that is later melted away. The intricacies and precision of lost-wax casting provide a high level of detail but differ from die casting's mass production capabilities and consistent dimensional accuracy.
Injection molding, which can involve die casting for metals, and other methods like extrusion and drawing, are compared in their capacity to form materials into desired shapes.
The use of die-casting in injection molding signifies its importance for producing complex and accurate dimensional parts efficiently.
The complete question is: With die casting, the component often has better dimensional accuracy than sand casting. Justify!
