Put simply, variations in pressure during the die-casting process will directly impact the final product, both in quality and in its characteristics. If the pressure is too low, the molten metal might not fully fill the mold, leading to parts that are incomplete or lacking detail on the surface. They could also come out weaker and less dense.
On the other hand, using too much pressure can cause the molten metal to infiltrate even the smallest crevices of the mold, leading to flash formation around the part—something you’ll need to spend time removing. Ultimately, using excessive pressure could make the mold wear and tear faster. That’s why choosing the right amount of pressure is really important.
