±pm$0.005mm Precision SKH51 Core Pins | Internal Riffled Wire for Plastic Tooling

Product Overview

SKH51 and SKD61 rifle wire components are precision-manufactured mold parts designed for internal cooling and cross-drilled flow channels in plastic injection moulds. These rifle tubes are produced with controlled straightness, concentricity, and surface integrity to ensure stable coolant flow and long-term performance in high-cycle, multi-cavity mould applications.

Key Features & Technical Advantages

• Manufactured from SKH51 or SKD61 tool steel

• Suitable for straight and cross rifle cooling structures

• High rigidity for deep-hole and long-length applications

• Stable dimensional accuracy along full tube length

• Smooth internal bore to support consistent coolant flow

• Compatible with complex mold cooling layouts

• Customized / OEM / Built-to-Print production

Applications & Industry Use

These rifle wire and cross rifle tube components are widely used in:

• Multi-cavity injection moulds for bottle caps and closures

• Packaging moulds requiring intensive internal cooling

• Medical plastic moulds with strict thermal control

• High-speed injection moulds with short cycle time requirements

They are essential components in molds where uniform temperature distribution and repeatable production stability are required.

Mold Structure & Design Description

In injection mould assemblies, rifle wire tubes are typically used as:

• Internal cooling channels for cores, cavities, or inserts

• Cross-drilled cooling connections between mold plates

• Precision-installed cooling elements inside thick mold sections

• Replaceable cooling components for mold maintenance

All rifle wire parts are manufactured strictly according to customer drawings, including diameter, length, straightness, and interface requirements.
