CNC Milling & Wire EDM Mold Parts | Custom Complex Core Inserts

Product Overview

CNC Milling Core Inserts with Wire Cutting Processing are precision mould components designed for injection tooling with complex or shaped geometries. By combining high-accuracy CNC milling and wire EDM processes, these inserts achieve precise contours, sharp internal features, and stable dimensional consistency, making them suitable for high-precision injection molds and multi-cavity tooling systems.

Key Features & Technical Advantages

• CNC milling for accurate 3D contours and complex geometries

• Wire cutting (EDM) processing for sharp corners and internal profiles

• Stable dimensional accuracy for shaped and non-standard mould inserts

• Optimized surface integrity for reliable mold performance

• Suitable for multi-cavity and precision injection mold structures

• Fully customized, built-to-print manufacturing based on customer drawings

Applications & Industry Use

• Injection molds with shaped or irregular core inserts

• Multi-cavity molds requiring consistent cavity geometry

• Packaging molds for bottle caps, closures, and containers

• Medical and laboratory plastic injection tooling

Mold Structure & Design Description

These core inserts are typically installed in mold cavity or core plates where complex shapes or tight internal features are required. CNC milling is used to generate primary geometries, while wire EDM ensures precision cutting of profiles that cannot be achieved through conventional machining. This hybrid process improves assembly accuracy, reduces fitting time, and enhances mold stability during production.

FAQ (Technical & Purchasing)

Q1: What types of shapes are suitable for wire cutting processing?
A: Wire EDM is ideal for sharp corners, internal contours, and complex profiles that cannot be milled directly.

Q2: Can you manufacture non-standard or irregular core inserts?
A: Yes. All inserts are produced according to customer drawings with no standard size limitations.

Q3: What tolerance range can be achieved?
A: Tolerances are controlled based on drawing requirements and mold function, typically within precision mold standards.

Q4: Do you support small-batch or replacement orders?
A: Yes. We support prototype, small-batch, and replacement production for existing molds.
