H13 (1.2344) Precision Mold Cores | Hardened Inserts for Injection Tooling

Product Overview

The 1.2344 hardened mold core insert from Senlan Precision is manufactured for plastic injection molds requiring high thermal stability, wear resistance, and dimensional consistency. Produced strictly according to customer drawings, these mold cores are designed for stable performance in medium- to high-cycle injection molding applications across packaging and medical tooling environments.

Key Features & Technical Advantages

• Manufactured from 1.2344 hot work tool steel (H13 equivalent)

• Hardened for improved wear resistance and thermal stability

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

• Suitable for single-cavity and multi-cavity injection mold systems

• Stable dimensional control for long production runs

• Designed for easy replacement and mold maintenance

Applications & Industry Use

This hardened mold core insert is widely used in:

• Plastic bottle and packaging injection molds

• Cap, closure, and dispensing component molds

• Medical disposable and syringe mold tooling

• Laboratory and healthcare plastic part molds

• High-output packaging and daily-use plastic molds

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

Mold Structure & Design Description

Mold cores made from 1.2344 steel act as the primary forming components within injection molds. Key structural considerations include:

• Accurate interface with cavity inserts and mold plates

• Optimized geometry for consistent plastic flow and cooling

• Structural rigidity under high injection pressure

• Compatibility with modular mold designs for fast servicing

Senlan Precision manufactures mold cores strictly according to approved designs without functional modification unless specified by the customer.

Manufacturing Capability & CNC Machining

Senlan Precision operates advanced precision machining equipment, including MAKINO (Japan) and HARDINGE (USA) CNC systems, ensuring stable and repeatable manufacturing quality.

Manufacturing capabilities include:

• High-precision CNC milling and turning
