Frequently Asked Questions
What is the function of ejector pins in die casting molds?
Ejector pins push the solidified casting out of the mold cavity after the casting process is completed.
When are ejector sleeves used instead of ejector pins?
Ejector sleeves are used when ejection needs to occur around a core pin or cylindrical feature, allowing uniform force distribution.
Why is H13 steel commonly used for ejector components?
H13 tool steel provides excellent heat resistance, toughness, and wear resistance, making it suitable for high-temperature die casting environments.
Can ejector pins and sleeves be customized?
Yes. These components can be manufactured based on custom drawings, mold designs, and tolerance requirements.
What tolerance can be achieved for these components?
Our manufacturing precision for die casting mold components can reach ± 0.005 mm.
