Medical Syringe Core Pins | Stavax Steel Multi-Cavity Mold Components

Product Overview

Senlan Precision supplies STAVAX mold core pins engineered for multi-cavity medical syringe injection moulds. Manufactured strictly to customer drawings (Built-to-Print), these core pins emphasize corrosion resistance, dimensional stability, and repeatable accuracy—key requirements for high-cavity, high-cycle medical moulding where process consistency and tool life are critical.

Key Features & Technical Advantages

• STAVAX stainless mould steel for enhanced corrosion resistance and clean processing

• Consistent hardness after controlled heat treatment for stable long-run performance

• Tight dimensional control suitable for multi-cavity syringe moulds

• Precision ground surfaces to support smooth demoulding and minimal wear

• Interchangeability support for cavity balance and maintenance efficiency

• Custom / OEM / Built-to-Print manufacturing only—no catalog parts

Application Scenarios / Industry Applications

• Medical syringe injection moulds (single-use and disposable)

• Multi-cavity medical consumables moulds

• Precision core pin systems for medical connectors and tubular components

• High-output moulds requiring stable cavity-to-cavity consistency

Mold Structure & Design Description

In multi-cavity syringe moulds, core pins define critical internal diameters and concentricity. STAVAX material provides corrosion resistance and dimensional stability under repeated cycles. Geometry, tolerances, surface finish, and mounting interfaces are produced exactly per customer drawings to ensure correct alignment, uniform filling, and reliable demoulding across all cavities.

Manufacturing Capability & CNC Machining Capacity

Senlan Precision operates advanced equipment for high-accuracy mould components, including:

• MAKINO high-precision CNC machining centers (Japan)
