Modern Advanced Mold Manufacturing Technology (Part 2)

With the continuous advancement of precision manufacturing, modern mold technology is moving toward intelligent design, digital integration, and rapid production. New-generation CAD/CAM software and advanced rapid manufacturing technologies are driving this transformation.

These innovations improve efficiency, reduce development time, and enhance manufacturing accuracy for high-precision industries.

Next-Generation Mold CAD/CAM Software Technology

New-generation mold CAD/CAM software developed in countries such as the United States, the United Kingdom, Germany, and leading research institutions introduces:

• Intelligent design capabilities
• Integrated engineering systems
• Mold manufacturability evaluation
• Knowledge-based engineering databases
• Advanced simulation tools

These systems are built on extensive design knowledge derived from practical mold engineering experience. The knowledge is structured and stored in engineering databases, allowing software to automatically apply expert-level decision-making during mold design.

Intelligent Design Support

Unlike traditional CAD tools that simply replicate manual calculations, next-generation software:

• Applies advanced design theory
• Uses expert engineering knowledge
• Optimizes mold structure automatically
• Improves design rationality and reliability

This results in more advanced and manufacturable mold designs.

3D Integrated Design and Simulation

Modern mold software uses three-dimensional modeling and visualization to design mold structures. These systems allow:

• 3D parametric feature modeling
• Forming process simulation
• Cooling and flow analysis
• CNC machining simulation
• Data integration and management

High-level integration ensures all modules share the same data model, forming a unified dynamic database. This supports:

• Mold design
• Manufacturing
• Assembly
• Inspection
• Testing
• Production launch

Mold Manufacturability Evaluation

Manufacturability evaluation is a key feature of next-generation mold software. It helps engineers:

• Compare multiple design options
• Evaluate structural feasibility
• Estimate manufacturing cost
• Assess assembly performance
• Analyze forming performance

These functions help optimize mold design before production begins, reducing risk and cost.

Assembly-Oriented Design

New-generation mold software also supports assembly-oriented design. Instead of assembling individual components manually, the system:

• Defines functional relationships between parts
• Creates associative component structures
• Ensures correct assembly alignment
• Improves overall mold quality

This approach significantly enhances reliability and production efficiency.

Advanced Rapid Mold Manufacturing Technology

1. Laser Rapid Prototyping Technology (RPM)

Laser rapid prototyping technology has developed quickly and is now widely used. Commercialized rapid prototyping methods include:

• SLA (Stereolithography)
• LOM (Laminated Object Manufacturing)
• SLS (Selective Laser Sintering)
• 3D Printing

These technologies enable fast creation of complex mold structures, reducing development cycles and improving design verification.

Rapid prototyping provides:

• Shorter design cycles
• Lower development cost
• High dimensional accuracy
• Flexible design modifications

2. Moldless Multi-Point Forming Technology

Moldless multi-point forming replaces traditional molds with adjustable pin arrays for sheet metal forming. This advanced manufacturing method:

• Uses CAD/CAM technology
• Enables rapid 3D surface forming
• Reduces tooling cost
• Improves production flexibility
• Supports complex surface shaping

This technology is gaining popularity in flexible manufacturing systems.

3. Resin Stamping Mold Technology

Resin stamping molds have been successfully applied in automotive prototype production. This method features:

• CAD/CAM-machined master models
• High-strength resin casting
• Precise gap control
• High dimensional accuracy
• Reduced manufacturing cycle (by 50%–66%)
• Significant cost savings

Resin molds provide an economical solution for small-batch production and prototype development.

Future Development Trends

Advanced mold manufacturing technologies continue evolving toward:

• Intelligent CAD/CAM integration
• Rapid prototyping adoption
• Flexible moldless forming
• Digital manufacturing workflows
• Cost-efficient small-batch production

These technologies will further enhance precision manufacturing industries.

Conclusion

Next-generation CAD/CAM software and rapid mold manufacturing technologies are transforming modern precision engineering. By combining intelligent design, simulation, and rapid production, manufacturers can significantly improve efficiency, reduce cost, and achieve higher accuracy.

These innovations play a key role in supporting advanced equipment manufacturing and future industrial development.
