S136 Precision Taper Core Pins are high-precision mold components designed for medical injection molding applications that require corrosion resistance, mirror surface finish, and micro-feature accuracy. These tapered core pins are typically used to form fine holes, micro cavities, and thin internal structures in medical plastic parts.
Manufactured from S136 stainless mold steel, these core pins offer superior corrosion resistance, excellent polishability, and stable dimensional accuracy. The tapered geometry improves demolding performance and reduces stress on delicate molded parts.
S136 taper core pins are widely used in molds producing medical consumables, laboratory plastics, pharmaceutical packaging components, and precision medical devices.
In medical injection molds, many components require very small internal features, thin pins, or deep micro holes. Standard straight core pins can cause sticking or damage to molded parts during ejection.
Taper core pins are designed to gradually reduce diameter toward the tip, which helps:
Using S136 stainless mold steel provides additional advantages in medical applications, including resistance to corrosion from moisture, plastic additives, or cleaning agents used in medical production environments.
Our S136 precision taper core pins are manufactured through precision CNC machining, micro grinding, and mirror polishing to achieve extremely smooth surfaces and tight tolerances.
These features make them ideal for high-precision medical injection molds and high-cavity production tools.
S136 precision taper core pins are widely used in medical and laboratory plastic injection molds where corrosion resistance and surface finish are critical.
Used for molds producing medical plastic components such as connectors, caps, and small functional parts.
Suitable for molds producing laboratory tubes, diagnostic parts, and micro plastic components.
Used in molds producing pharmaceutical plastic closures and packaging accessories.
Ideal for molds requiring micro cavities, thin wall structures, and precision holes.
Ensures consistent dimensional accuracy across multi-cavity molds running high-volume production.
We manufacture precision medical mold components using advanced machining technology and strict quality control.
Special attention is given to surface finish, straightness, and concentricity, which are essential for medical injection molding components.
S136 stainless mold steel resists corrosion caused by moisture, cleaning agents, or aggressive plastics used in medical applications.
Mirror polishing capability ensures smooth plastic flow and excellent molded surface finish.
The tapered design reduces demolding resistance and protects delicate molded features.
Wear-resistant material and precision machining improve durability and reduce maintenance.
Consistent dimensional accuracy supports continuous operation in multi-cavity medical molds.
