M340 Long Taper Core Pins for Medical Injection Molds
Product Overview
M340 Long Taper Core Pins are high-precision mold components designed for medical injection molds that require deep tapered cores and ultra-fine internal structures. These pins are commonly used to create long micro holes, tapered channels, and deep cavity features in medical plastic components.
Manufactured from Böhler M340 stainless mold steel, these core pins offer excellent corrosion resistance, superior hardness, and outstanding polishability. The long tapered structure allows precise formation of deep internal geometries while improving demolding performance.
M340 long taper core pins are widely used in high-precision medical molds, laboratory consumable molds, and micro injection molding tools, where both structural strength and micro-level accuracy are required.
Product Description
Medical injection molded parts often contain deep internal holes or narrow tubular structures that require long core elements inside the mold. Standard straight pins can cause high friction during demolding and may damage delicate plastic parts.
Long taper core pins solve this problem by combining extended pin length with a gradual taper geometry. This design provides several key advantages:
- Smooth demolding for deep molded features
- Reduced friction between the plastic part and the core pin
- Improved plastic flow around thin core structures
- Lower risk of deformation or breakage of molded parts
The use of M340 stainless mold steel further improves the performance of these mold components. Compared with standard tool steels, M340 provides:
- Excellent corrosion resistance
- High wear resistance in long production cycles
- Superior mirror polishing capability
- Stable dimensional accuracy
Our M340 long taper core pins are manufactured using advanced machining technologies such as precision CNC turning, taper grinding, and mirror polishing to ensure excellent straightness and high dimensional stability.
