Hardened AISI M2 (SKH51) Cavity Inserts | 60 HRC Precision Mold Components

Product Overview

AISI standard plastic insert molding cavity inserts with 60 HRC hardness are engineered for injection molds requiring high wear resistance, dimensional stability, and long service life. Manufactured by Senlan Precision strictly to customer drawings, these hardened cavity inserts are suitable for demanding multi-cavity and high-cycle injection molding applications in packaging and medical tooling.

Key Features & Technical Advantages

• AISI standard tool steel with hardened condition up to 60 HRC

• Excellent wear resistance for long production cycles

• Stable dimensional accuracy under thermal and injection pressure loads

• Built-to-Print manufacturing based on customer drawings or 3D data

• Suitable for single-cavity and multi-cavity mold configurations

• Optimized for repeatability and mold maintenance efficiency

Applications & Industry Use

These cavity inserts are widely applied in:

• Plastic bottle and container packaging molds

• Caps, closures, and dispensing component molds

• Medical disposables and syringe injection molds

• Laboratory and healthcare plastic part tooling

• Daily-use and hygienic packaging injection mold systems

All applications relate strictly to industrial injection mold tooling, not finished consumer products.

Mold Structure & Design Description

Mould cavity inserts form the critical shaping surfaces within plastic injection molds. For 60 HRC hardened inserts, design considerations include:

• Accurate fit with mold base and insert pockets

• Controlled draft angles and surface finish for consistent demolding

• Structural rigidity for multi-cavity layouts

• Compatibility with replaceable insert mold designs

Senlan Precision manufactures cavity inserts strictly according to approved customer designs without functional alteration unless specified.

Manufacturing Capability & CNC Machining

Senlan Precision operates advanced CNC machining equipment from MAKINO (Japan) and HARDINGE (USA) to ensure stable, high-precision production.

Manufacturing capabilities include:

• High-precision CNC milling and turning

• EDM machining for complex cavity geometries

• Surface grinding and controlled polishing

• Heat treatment to achieve consistent 60 HRC hardness

• In-process and final dimensional inspection

All processes follow drawing-defined tolerances and specifications.
