S136 Medical Mold Inserts | Precision Mirror EDM Core Components

Product Overview

Senlan Precision provides S136 hardened plastic core inserts manufactured with EDM (spark discharge) processing for medical plastic injection molds. These core inserts are built-to-print components designed for high dimensional stability, corrosion resistance, and repeatable precision in multi-cavity and high-cleanliness molding environments.

Key Features & Technical Advantages

• S136 stainless mould steel with high corrosion resistance and stable hardness

• EDM (spark discharge) processing for complex geometries and sharp internal features

• Consistent dimensional accuracy suitable for multi-cavity medical molds

• Excellent surface integrity after polishing or secondary finishing

• Stable performance under continuous injection molding cycles

• Fully customized dimensions based on customer drawings or specifications

Application Scenarios / Industry Applications

• Medical consumables injection molds

• Syringe components and medical connectors

• Diagnostic and laboratory plastic parts

• Precision thin-wall medical packaging

• Cleanroom-grade injection mold tooling

Mold Structure & Design Description

These core inserts are typically integrated into multi-cavity medical molds where tight tolerances and surface integrity are required. EDM processing allows accurate formation of ribs, slots, and internal profiles that are difficult to achieve through conventional milling. Insert geometry, venting details, and fitting tolerances are manufactured strictly according to customer-provided drawings to ensure proper mold assembly and part consistency.

Manufacturing Capability & CNC Machining Capacity

Senlan Precision operates advanced precision machining equipment, including:

• MAKINO high-speed CNC machining centers (Japan)

• HARDINGE precision turning and milling systems (USA)

• High-accuracy EDM and wire-cut machines

• Precision grinding and polishing processes

These capabilities enable stable control of concentricity, flatness, and dimensional repeatability for medical mold components.
