Molding, temperature, holding pressure

Die Casting

1. Shrinkage is an important consideration.
2. Die casting is done by injecting molten metal into a mold and then waiting for it to cool and solidify into the desired shape.
3. During this process, the metal will experience shrinkage, that is, volume reduction.
 

Shrinkage

1. It is a percentage or ratio that describes the change in volume.
2. Typically, the supplier or manufacturer of the fabrication material will provide a predicted shrinkage for the die cast metal.
3.This value is determined by factors such as metal type, temperature, and pressure.

Practical Application of Mold Flow Analysis

1. Understanding shrinkage is crucial because it directly affects the size and accuracy of the final product.
2. When designing molds and models, shrinkage must be considered to ensure that the final product meets the expected dimensional requirements.
3. In addition, subsequent trimming or correction may be required during the manufacturing process to compensate for dimensional changes caused by shrinkage.
