M340 Medical Core Pins for Precision Medical Injection Molds
M340 Medical Core Pins are high-precision mold components designed for medical injection molding applications that require corrosion resistance, dimensional stability, and ultra-fine feature formation. These core pins are used to create small holes, internal channels, and precision structural features in molded medical plastic components.
Product Overview
Manufactured from Bohler M340 stainless mold steel, these core pins provide excellent corrosion resistance, superior hardness, and exceptional polishability. These properties make them particularly suitable for medical injection molds that require long production cycles and strict quality standards.
M340 medical core pins are widely used in molds producing medical consumables, laboratory plastic products, pharmaceutical packaging components, and other precision medical plastic parts.
Product Features
Core pins are essential components in injection molds used to form internal geometries and precision holes in molded plastic parts. In medical injection molding, these features are often extremely small and require very high dimensional accuracy.
Because medical molds often run high-volume production with strict quality control, the core pins must maintain consistent performance under repeated thermal cycles, injection pressure, and mechanical stress.
