Design & Development Process

Step 03
Engineering Drawing & Tooling Design Confirmation

After confirming the development direction and initial cost estimation, ECHO METALART moves into the formal engineering design stage. The core of this step is precision, manufacturability, and verification.

Professional 3D Modeling & Engineering Design

Our engineering team utilizes SolidWorks for 3D modeling and engineering design, transforming concepts into manufacturable structures, including:

  • Complete 3D models (3D Modeling)
  • Structural layout and component configuration (Engineering Design)
  • Tooling part separation and assembly logic planning

By establishing accurate 3D models early, we can clearly evaluate proportions and structural details before mold development, significantly reducing the risk of later modifications.

Supported File Formats

To ensure smooth communication and cross-functional collaboration, we support widely used international file formats. This allows seamless integration across design, tooling, and manufacturing processes.

Detailed Dimensions, Tolerances & Finishing Specifications

Detailed Tooling Molds Extensive Mold Library

All engineering drawings clearly definetechnical requirements to ensure consistency across tooling, sampling, and mass production.

  • Dimensions and tolerance ranges for each component
  • Critical structural and load-bearing areas
  • Surface finishing and plating zones
  • Assembly methods and part-fit relationships

These drawings serve as the official reference for tooling fabrication, sampling, and mass production.

Structural Strength & Durability Optimization

With extensive experience in metal hardware and belt buckle development, our engineering team simultaneously evaluates:

  • Structural stability and load distribution
  • Thickness optimization, chamfering, and connection details
  • Product lifespan and long-term durability
  • Material behavior during high-pressure die casting

While preserving the intended design appearance, we ensure that each product meets practical usage requirements and mass-production standards.
