M340 Long Taper Core Pins for Medical Injection Molds
High-precision mold components designed for medical injection molds requiring deep tapered cores and ultra-fine internal structures.
Product Overview
M340 Long Taper Core Pins are engineered for medical injection molds that require deep tapered cores and ultra-fine internal structures. These specialized pins create long precision holes, tapered channels, and deep cavity features in medical plastic components.
Manufactured from Bohler M340 stainless mold steel, these core pins provide exceptional corrosion resistance, superior hardness, and outstanding polishability. The long tapered structure enables precise formation of deep internal geometries while enhancing demolding performance.
These components are widely used in high-precision medical molds, laboratory consumable molds, and precision injection molding tools where both structural strength and precision-level accuracy are essential.
