STAVAX (AISI 420) Cavity Inserts | Precision Tooling for Thin-Wall Packaging

Product Overview

STAVAX High Precision Mold Components – Cavity Inserts for Thin Wall Packaging are engineered mould cavity parts designed for high-speed, multi-cavity injection moulds requiring excellent surface finish, corrosion resistance, and dimensional stability. Manufactured by Senlan Precision, these cavity inserts are produced strictly on a custom / OEM / Built-to-Print basis to meet the demanding requirements of thin wall packaging applications.

Key Features & Advantages

• Manufactured from STAVAX stainless mould steel for corrosion resistance

• High dimensional accuracy suitable for thin wall moulding

• Stable performance in high-cycle, high-cavitation moulds

• Excellent polishability for smooth cavity surfaces

• Consistent cavity-to-cavity repeatability

• Designed for easy replacement and maintenance

Applications / Industry Use

• Thin wall packaging moulds

• Bottle and container packaging systems

• High-speed cap and closure moulds

• Medical packaging mould components

• Multi-cavity injection mould tooling for packaging products

Mould Structure & Design Description

Cavity inserts form the functional mould surface that defines the external geometry and wall thickness of the molded part. In thin wall packaging moulds, cavity design requires precise control of:

• Wall thickness uniformity

• Dimensional consistency across multiple cavities

• Surface finish quality to support demoulding and appearance requirements

• Thermal stability under high injection speeds and pressures

All cavity inserts are manufactured according to customer-supplied drawings and mould specifications, ensuring compatibility with existing mould bases and hot runner systems.

Manufacturing Capability & CNC Machining

Senlan Precision applies controlled machining processes to achieve high accuracy and surface quality, including:

• High-precision CNC milling

• CNC turning for reference and positioning features

• Precision grinding for critical surfaces

• Polishing processes suitable for thin wall cavity requirements

• Optional EDM for complex internal details

Production is supported by advanced machining equipment from MAKINO and HARDINGE, ensuring stable tolerances and consistent surface quality suitable for export-grade mould components.
