CMM Tested 1.2344 Cavity Mold Parts

Precision Mold Components for the Packaging Industry

Product Overview

Our 1.2344 cavity mold parts are precision-engineered components used in high-cycle injection molds for the packaging industry.

Each cavity component is:

• CNC machined

• Heat treated

• Surface finished

• Fully inspected by CMM (Coordinate Measuring Machine)

These parts are critical in forming the final geometry of packaging products such as caps, containers, closures, and thin-wall packaging components.

All components are manufactured strictly according to customer drawings.

Typical Applications

These cavity mold parts are widely used in:

• Bottle cap molds

• Cosmetic packaging molds

• Food container molds

• Thin-wall injection molds

• Multi-cavity packaging molds

• Medical packaging molds

Especially suitable for 8, 16, 32+ cavity systems where dimensional consistency is critical.

Material – 1.2344 (H13 Equivalent)

1.2344 tool steel is selected for packaging mold cavities because it provides:

• High wear resistance

• Good thermal fatigue resistance

• Stable hardness after heat treatment

• Long mold life in high-speed production

Typical hardness range:
48–52 HRC (customizable based on application)

Other material options available:

• SKD61

• S136

• SKD11

• SKH51

Material selection depends on resin type and expected mold life.

Engineering Focus

In packaging molds, cavity precision directly affects:

• Product wall thickness

• Thread accuracy

• Sealing performance

• Surface appearance

Key control points include:

1) Dimensional Accuracy

• Precision tolerance: ±0.005 mm to ±0.01 mm

• Axiality control

• Verticality control

• Insert seat matching accuracy

Critical features are ground after heat treatment to ensure stability.

2) Multi-Cavity Consistency

For high-cavity molds:

• Cavity inserts are batch-machined

• Simultaneous boring improves alignment

• Controlled grinding ensures identical geometry

This reduces variation between cavities and minimizes flashing or leakage issues.

3) Surface Treatment Options

Depending on production requirements:

• Nitriding

• TiN / TiAlN / TiCN coating

• Polishing

• Custom surface finishing

Surface treatment improves wear resistance and extends maintenance intervals.

CMM Inspection & Quality Control

All cavity mold parts are inspected using CMM equipment to verify:

• Key dimensions

• Concentricity

• Alignment features

• Surface geometry

Inspection reports are available upon request.

The quality control process includes:

• Raw material verification

• In-process inspection

• Final dimensional verification

• Hardness testing after heat treatment

Manufacturing Capability

Production processes include:

• High-speed CNC machining

• EDM & Wire EDM

• Precision grinding

• Surface polishing

• Heat treatment coordination
