S136 Mirror-Finish Cavity Inserts | Precision Tooling for Cosmetic Packaging

Product Overview

S136 Components Cavity Inserts for Injection Molding by Senlan Precision are high-accuracy mould components manufactured for cosmetic packaging applications that require excellent surface quality, corrosion resistance, and dimensional stability. Produced strictly on a custom / OEM / Built-to-Print basis, these cavity inserts are designed to integrate seamlessly into multi-cavity or single-cavity mould systems with stable long-term performance.

Key Features & Advantages

• Manufactured from S136 stainless mould steel for corrosion resistance

• Suitable for high-polish and fine surface finish requirements

• Stable hardness distribution after heat treatment

• Tight dimensional tolerances for cavity-to-cavity consistency

• Optimized for multi-cavity cosmetic packaging moulds

• Fully customized according to customer drawings (Built-to-Print)

Applications / Industry Use

• Cosmetic packaging moulds (caps, closures, containers)

• Bottle and packaging component mould tooling

• Medical packaging moulds requiring clean surface quality

• Multi-cavity injection mould systems

• Precision mould refurbishment and replacement inserts

Mould Structure & Design Description

Cavity inserts form the primary shaping surfaces of injection moulds. Their dimensional accuracy, surface finish, and material stability directly affect part appearance and mould lifespan. Senlan Precision manufactures S136 cavity inserts according to customer-defined geometry, ensuring proper fit, thermal stability, and uniform cavity performance across mould layouts.

Manufacturing Capability & CNC Machining

Senlan Precision applies controlled precision machining processes for cavity inserts:

• High-precision CNC milling and turning

• EDM and wire-cut EDM for complex cavity geometries

• Precision grinding for critical interfaces and tolerances

• Controlled heat treatment for S136 material

• Fine polishing processes aligned with cosmetic packaging requirements

Machining is supported by advanced equipment including MAKINO (Japan) and HARDINGE (USA) CNC systems to ensure consistency and repeatability.
