Stavax S136 Mold Core Inserts | Precision Parts for Plastic Bottle Molds

Product Overview

Stavax S136 mould steel core inserts are precision components used in plastic bottle making molds, requiring high corrosion resistance, dimensional stability, and consistent surface quality. Manufactured under a built-to-print model, these inserts are designed for long production cycles and stable performance in multi-cavity injection molding systems.

Key Features & Technical Advantages

• Manufactured from Stavax / S136 stainless mould steel

• Excellent corrosion resistance for moisture-sensitive molding environments

• Stable hardness distribution suitable for long-term production

• High dimensional accuracy and repeatability for multi-cavity molds

• Fine surface finish supporting consistent bottle geometry

• Fully customized / non-standard production based on customer drawings

Applications & Industry Use

• Plastic bottle injection molds

• Packaging molds for daily chemicals and liquid containers

• Medical and laboratory plastic container molds

• High-volume, multi-cavity bottle manufacturing systems

• Precision mold assemblies requiring corrosion-resistant inserts

Mold Structure & Design Description

The S136 core insert is typically installed within the cavity or core assembly of bottle molds. Design focuses on concentricity, cooling efficiency, and surface integrity. Proper fit and tolerance control ensure stable demolding, uniform wall thickness, and consistent product quality across all cavities.
