Precision D2 Die Steel Core Inserts | Custom Wire EDM Mold Components (OEM/ODM)

Product Overview

Senlan Precision supplies OEM / ODM core insert precision mould parts manufactured from D2 (1.2379) die steel, featuring wire cutting (EDM) processing for complex geometries and tight tolerances. These components are produced strictly under Built-to-Print requirements and are designed for stable performance in precision injection molds.

Key Features & Technical Advantages

• D2 cold work die steel with high wear resistance and dimensional stability

• Wire cutting (EDM) for complex contours, sharp corners, and fine features

• Suitable for long production runs and high-cycle injection molds

• Stable hardness after heat treatment, minimizing deformation risk

• Precision machining for consistent core-to-cavity alignment

• Fully customized OEM / ODM manufacturing based on drawings

Application Scenarios / Industry Applications

• Bottle cap and closure injection molds

• Precision packaging plastic molds

• Medical and laboratory plastic component molds

• Multi-cavity injection molds requiring consistent core geometry

• High-wear mold areas where tool life is critical

Mold Structure & Design Description

D2 die steel core inserts are commonly used as threaded cores, shaped cores, or functional mold inserts. Wire cutting enables accurate formation of internal profiles, parting features, and sharp edges that are difficult to achieve by conventional milling. The inserts are designed to integrate seamlessly into core plates or cavity blocks, ensuring repeatable molding accuracy.
