High Light core pin injection molding ，precision core pins
H13 Venting Core Pins for Medical Injection Molds
Specialized mold components designed to improve air evacuation in precision medical injection molds. These pins combine core formation and mold venting functions, allowing trapped air and gases to escape during the injection process.
Product Overview
Manufactured from H13 hot-work tool steel, venting core pins provide high strength, excellent wear resistance, and stable performance under continuous injection molding cycles. Their precision-vent structure helps reduce common molding defects such as burn marks, short shots, and trapped gas, which are especially critical in medical-grade plastic parts.
These venting core pins are widely used in medical injection molds requiring high dimensional precision, stable molding conditions, and high cavity productivity.
Product Features
  • Made from H13 hot-work tool steel
  • Integrated core forming and venting function
  • Precision precision-vent structures for gas evacuation
  • High resistance to wear, pressure, and heat
  • Smooth surface finishing for stable molding cycles
  • Designed for high-precision medical injection molds
  • Custom dimensions and venting structures available
  • Machining tolerance up to ± 0.005 mm
Applications
Medical Device Components
Used in molds producing precision plastic components for medical devices requiring defect-free surfaces.
Laboratory Consumables
Applicable for molds producing laboratory plastic parts such as precision tubes, connectors, and diagnostic components.
precision Injection Molded Parts
Ideal for molds forming small cavities or precision features where air entrapment can affect molding quality.
Thin Wall Plastic Medical Components
Used in thin-wall molding processes where air evacuation must occur quickly during cavity filling.
High-Cavity Medical Injection Molds
Ensures stable molding performance across multiple cavities with consistent air venting.
Precision & Manufacturing Capabilities
  • High precision CNC turning and precision machining
  • precision grinding and polishing
  • Precision control of vent clearance structures
  • Professional vacuum heat treatment
  • Strict dimensional inspection
  • Machining tolerance up to ± 0.005 mm
Benefits for Medical Injection Molding
Effective Gas Evacuation
Venting core pins help release trapped air and gases during cavity filling, improving mold performance.
Reduced Molding Defects
Proper venting reduces the risk of burn marks, short shots, and surface defects.
Stable High-Volume Production
Reliable venting supports the continuous operation of high-cavity medical molds.
Improved Product Surface Quality
Better air evacuation results in smoother molded surfaces and consistent part quality.
Longer Mold Service Life
Durable H13 material ensures long-term stability under repeated molding cycles.
Quotation Requirements
To provide an accurate quotation for custom venting core pins, please provide:
  • 2D drawings or 3D CAD files
  • Core pin diameter and length
  • Venting structure requirements
  • Tolerance requirements
  • Material specification (H13 or equivalent)
  • Surface treatment or finishing requirements
  • Order quantity
  • Mold application details
Frequently Asked Questions
What is a venting core pin in injection molds?
A venting core pin is a mold component that allows air and gases to escape from the cavity during injection molding while simultaneously forming internal features of the molded part.
Why are venting core pins important in medical injection molds?
Medical parts often require high surface quality and precision, and trapped air can cause defects. Venting core pins help maintain consistent molding quality.
Why is H13 steel used for venting core pins?
H13 tool steel provides excellent wear resistance, strength, and thermal stability, making it suitable for high-cycle injection molding.
Can venting core pins be customized?
Yes. Vent structure, pin diameter, length, and tolerances can all be custom-manufactured according to mold design requirements.
What tolerance can be achieved?
Our precision machining capabilities allow dimensional tolerances up to ±0.005 mm for mold components.
