Product Specification

Mold & Die Core Inserts – Precision 5-Axis Mold Core Machining

Our Mold & Die Core Inserts are manufactured using advanced 5-axis CNC machining technology, specifically designed for producing precision mold parts with complex cavities, deep pockets, and intricate curved surfaces.

Mold cores and die inserts require exceptional dimensional accuracy, smooth surface finish, and precise geometric consistency. With simultaneous 5-axis machining, we can process complex cavity structures in a single setup, significantly improving accuracy while reducing secondary finishing work.

We provide fully customized mold core machining solutions for injection molds, die-casting molds, and high-precision tooling systems.

 Precision Mold Machining Capabilities

We specialize in machining:

• Mold core inserts
• Die cavity inserts
• Deep cavity components
• Complex 3D curved mold surfaces
• High-precision mold structural parts
• Replaceable precision insert blocks

5-axis simultaneous contouring allows accurate machining of undercuts, angled surfaces, and deep pocket structures that are difficult to achieve with traditional 3-axis machining.

Custom Mold Core Manufacturing Service

All mold and die components are custom manufactured based on:

• 2D drawings
• 3D CAD files (STEP / IGES)
• Technical tolerance specifications
• Surface finish requirements

Our engineering team provides DFM (Design for Manufacturability) feedback to optimize tool path strategy, reduce polishing time, and improve machining efficiency.

We support:

• Prototype mold components
• Replacement core inserts
• Small-batch tooling production
• Long-term tooling supply programs

Technical Highlights

• Simultaneous 5-axis contour machining
• Precision cavity geometry control
• Deep cavity and narrow pocket machining
• Tolerance up to ±0.01 mm depending on structure
• Excellent surface finish to reduce manual polishing
• Machining of tool steels, alloy steels, and hardened materials

Typical Applications

• Injection mold core inserts
• Die-casting cavity inserts
• High-precision tooling components
• Automotive mold parts
• Electronic housing mold cores

FAQ – Mold Core & Die Insert Machining

Q1: Why is 5-axis machining important for mold core inserts?

5-axis machining allows the cutting tool to approach complex cavity surfaces from multiple angles in a single setup, improving dimensional accuracy and reducing tolerance stacking errors.

Q2: Can you machine deep cavity mold components?

Yes. Our equipment and programming strategies are optimized for deep pocket and narrow cavity machining while maintaining structural precision.

Q3: Do you provide custom die insert machining services?

Yes. All mold cores and die inserts are custom manufactured based on customer drawings or 3D models. We do not provide standard catalog parts.

Q4: What materials can be used for precision mold parts?

We commonly machine various tool steels, pre-hardened steels, alloy steels, and other mold-grade materials depending on project requirements.

Q5: How do you ensure surface quality for mold cavities?

Through optimized tool path programming and precision multi-axis machining, we reduce machining marks and minimize secondary polishing requirements.

Q6: Can you support small-batch tooling production?

Yes. We support both prototype tooling components and small-batch precision insert production programs.
