HRC 58 Precision EDM Mold Parts | Custom Mirror Finish Injection Inserts

Product Overview

Senlan Precision manufactures HRC 58 injection mould components using Electric Spark Discharge (EDM) for complex geometries and tight tolerances. Produced strictly Built-to-Print, these parts are designed for stable performance in high-cavity injection moulds, combining controlled hardness, dimensional accuracy, and repeatable surface integrity for long production runs.

Key Features & Technical Advantages

• Controlled hardness up to HRC 58 after verified heat treatment

• EDM capability for sharp corners, deep ribs, and intricate profiles

• Stable dimensional accuracy for multi-cavity mould applications

• Suitable for wear-critical mould areas requiring consistent geometry

• Material and process selection aligned to customer drawings

• Custom / OEM / Built-to-Print only (no off-the-shelf parts)

Application Scenarios / Industry Applications

• Injection mould components for bottle caps and closures

• Packaging mould parts requiring complex internal features

• Medical consumables mould components with precise geometry

• High-output multi-cavity moulds where consistency is critical

Mold Structure & Design Description

These components are typically used in core, cavity, or functional mould areas where conventional machining cannot achieve the required geometry. EDM processing enables precise feature formation after heat treatment to HRC 58, ensuring dimensional fidelity without inducing cutting stress. Final geometry, tolerances, and surface conditions follow customer-supplied drawings to ensure correct mould fit and performance.

Manufacturing Capability & CNC Machining Capacity

Senlan Precision operates advanced machining and finishing resources, including:

• MAKINO high-precision CNC machining centers (Japan)

• HARDINGE CNC turning systems (USA)

• Precision EDM (spark erosion) for hardened materials

• Grinding and polishing for functional surfaces

• In-process inspection and final dimensional verification

These capabilities support reliable production of hardened mould components with complex shapes.

FAQ – Technical & Procurement

Q1: Is HRC 58 suitable for injection mould components?
Yes. HRC 58 provides good wear resistance for mould areas subject to repeated cycles.

Q2: Why use EDM instead of CNC cutting?
EDM allows accurate machining of hardened materials and complex geometries that are difficult or impossible with conventional cutting.

Q3: Do you manufacture only according to drawings?
Yes. All parts are produced strictly Built-to-Print.

Q4: Can surface finish requirements be specified?
Yes. Surface condition and finishing requirements are defined by the drawing and application.

Q5: Do you support low-volume or replacement orders?
Yes. Prototype, small batch, and maintenance replacement orders are supported.
