M340 Precision Taper Core Pins for Medical Injection Molds
High-performance mold components designed for medical injection molding tools requiring superior corrosion resistance, mirror polishing capability, and long service life.
Product Overview
M340 Precision Taper Core Pins are engineered for medical injection molding tools that demand exceptional performance. These tapered pins create precision holes, internal cavities, and thin precision structures in molded medical plastic components.
Manufactured from Bohler M340 stainless mold steel, these core pins provide outstanding hardness, excellent corrosion resistance, and superior polishability. The tapered design enhances demolding performance and protects delicate molded parts during ejection.
Ideal for high-precision medical molds, pharmaceutical packaging molds, and laboratory consumable molds where consistent dimensional accuracy and high surface quality are essential.
Product Description
In precision medical injection molds, plastic components often require extremely small core features and deep thin cavities. Straight core pins can cause sticking, deformation, or excessive friction during part release.
Taper core pins feature a gradual diameter reduction toward the tip, enabling smoother demolding and reducing stress on molded plastic parts.
