How Ejection System Design Impacts Mold Performance

In injection molding, it’s not enough to fill a cavity—the part must also be ejected cleanly and consistently. Poor ejection design leads to part deformation, sticking, or even mold damage. At Dongxinda, we engineer each mold with a tailored ejection system based on the shape, size, and function of your part.

From ejector pins and sleeves to stripper plates and air poppers, we apply the right method to ensure smooth, stress-free part removal. Our team also uses simulation tools to predict ejection force and avoid cycle delays or part distortion.

Clean ejection is crucial for automated production, cosmetic parts, and thin-walled components. Trust Dongxinda to deliver molds that don’t just shape your parts—they protect your process.

FAQs:

• What ejection systems do you offer?
  We support pins, blades, sleeves, plates, lifters, and hybrid systems.

• Can ejection issues be fixed in existing molds?
  Yes, we can adjust ejector layouts or add air-assisted systems.

• Is ejection force calculated during design?
  Definitely—we simulate it to ensure safe and fast part removal.
