Does die casting also have shrinkage?
Shrinkage is an important consideration when we talk about die casting, a method of manufacturing metal parts that involves pouring molten metal into a mold and then waiting for it to cool and solidify into the desired shape.
During this process, the metal undergoes shrinkage, which is a shrinkage in volume.
1.Shrinkage rate:
Is a percentage or ratio that describes a change in volume.
Typically, the supplier or manufacturer of manufacturing materials will provide a predicted shrinkage rate for die-cast metals, which is based on factors such as metal type, temperature, pressure, and more.
2. Die casting evaluation considerations:
It is crucial to understand the shrinkage rate because it directly affects the size and accuracy of the final product. When we design the mold, we must consider the shrinkage rate to ensure that the final product meets the expected size requirements. In addition, follow-up steps may be required during the manufacturing process. Trimming or correction to compensate for dimensional changes caused by shrinkage.
Shrinkage is a parameter that cannot be ignored in the die-casting process. It is crucial to ensure the accuracy of the product and to control it within the tolerance range.
