Collapsible cores are precision-engineered components used within injection molds to form complex internal geometries. They allow for the automated ejection of parts with threads or undercuts without the need for unscrewing mechanisms. This significantly improves production efficiency and cycle times, making them a critical component in high-volume manufacturing of packaging, cosmetics, and medical device components.
The functionality of a collapsible core depends entirely on its precision manufacturing. At SENLAN, we achieve the tight tolerances required for flawless operation, with accuracy held at +/- 0.005mm. Our advanced equipment, including Hardinge CNC lathes and Makino milling centers, allows us to machine the complex moving parts of the core to perfection, ensuring seamless collapse and expansion for every cycle.
Premium materials, durable performance. The foldable core withstands immense mechanical stress and must maintain its precision after millions of cycles. Therefore, we select only premium materials from leading brands, such as Borel steel. Each component undergoes factory-certified heat treatment to maximize hardness, wear resistance, and dimensional stability, ensuring a long and reliable service life for your molds.
