Applications & Industries

These medical syringe core pin mold inserts are widely used in:

• Injection molds for medical syringes

• Mold systems for syringe barrels and related medical components

• Medical plastic molds requiring strict dimensional consistency

• High-precision molds for disposable medical consumables

They are particularly suitable for applications requiring high precision, stable surface performance, and controlled wear behavior.

Mold Structure & Design Description

Core pin mold inserts are installed on the core side of syringe injection molds and directly define internal product geometry.
Key design considerations include:

• Accurate pin diameter and straightness for syringe barrel formation

• Proper fit and alignment with surrounding mold components

• Structural strength to withstand injection pressure and repeated cycles

• Compatibility with multi-cavity medical mold layouts

All inserts are designed and manufactured strictly according to customer drawings to ensure correct assembly and stable mold operation.

Manufacturing Capability & CNC Machining

Senlan Precision manufactures medical mold core pins and inserts using advanced CNC machining and finishing technologies.
Our production facilities are equipped with high-precision machining centers and CNC lathes from MAKINO (Japan) and HARDINGE (USA), along with other internationally recognized equipment, enabling:

• Machining accuracy up to ±0.002 mm

• Stable tolerance control for slender and high-precision core pins

• Consistent surface quality prior to coating

• Reliable repeatability for medical mold components

TiN coating is applied after machining and surface preparation to ensure uniform coating thickness and performance.

Technical FAQ

Q1: Are syringe core pins manufactured strictly according to drawings?
Yes. All medical mold core pins and inserts are produced strictly based on customer-provided drawings and specifications.

Q2: What is the function of TiN coating on core pins?
TiN coating improves wear resistance, reduces friction, and helps maintain surface stability during long production runs.

Q3: What tolerance levels can be achieved?
Depending on geometry and length, machining accuracy up to ±0.002 mm can be supported.

Q4: Can these inserts be supplied as replacement parts for existing medical molds?
Yes. Replacement and interchangeable core pin inserts can be manufactured to match existing mold designs.
