H13 Precision Tapered Core Pins for Medical Injection Molds
H13 Precision Tapered Core Pins are specialized mold components designed for high-precision medical injection molding applications. These tapered core pins are used to form small holes, thin internal channels, and precision cavities in plastic medical parts.
Manufactured from H13 hot-work tool steel, these core pins provide excellent resistance to wear, high temperatures, and mechanical stress during continuous injection molding cycles. The tapered geometry improves mold release performance and ensures high dimensional accuracy for delicate molded components.
Precision tapered core pins are widely used in molds producing medical consumables, laboratory plastics, and precision-structured plastic components, where dimensional stability and surface quality are critical.
Product Features
Tapered core pins are used inside injection molds to create internal features or deep precision holes in molded plastic parts. Compared with standard straight core pins, tapered designs improve part release and reduce the risk of part sticking or deformation during ejection.
In medical injection molding, molds often produce components with very small diameters, thin walls, and complex internal geometries. Precision tapered core pins help ensure consistent molding quality and prevent defects such as flash, burrs, or deformation.
These pins are manufactured using high-precision CNC machining, precision grinding, and polishing processes to achieve tight dimensional control and smooth surface finishes.
