High Flatness S136 Steel Core Insert with HRC58 Hardness and Precision Inner Grinding for Plastic Injection Bottle Cap

Internal thread cores are essential components for plastic parts that require screw-together functionality, such as bottle caps, drinkware lids, and plastic hardware. The delicate nature of threads demands specialized molding approaches to prevent damage during ejection.

Traditional methods required manual unscrewing from thread cores to avoid thread stripping, adding significant labor, time, and cost. Our automated solution eliminates these inefficiencies while ensuring faster production and error-free parts.
