Structural prototypes are physical models used to verify and test the structure and function of a product during product development. Unlike appearance prototypes, structural prototypes focus mainly on the structural integrity, functional testing, and assembly methods of the product. Here are details about the main features, production process, and application areas of structural prototypes.

Main Features
Functionality: Structural prototypes are usually designed to simulate the actual functions of a product, including moving parts and connection methods.
Material Selection: A variety of materials can be used, including plastics, metals, or composites, depending on the needs of the product.
Strength and Durability: Structural prototypes need to have a certain strength to withstand the pressure and loads during testing and evaluation.

Production Process
Design Phase:
Use CAD software to carry out detailed structural design and generate a 3D model.
Determine the structural, size, and functional requirements of the prototype.
Material Selection:
Choose appropriate materials such as ABS, PLA, aluminum alloy, etc. according to the application to ensure the strength and durability of the prototype.
Processing Methods:
CNC Processing: Suitable for structural prototypes that require high precision and strength.
3D Printing: Suitable for rapid prototyping and can quickly verify the design.
Injection molding: If mass production is required, injection molding is an effective choice.
Assembly and testing:
Assemble the individual components into a complete structural prototype for functional testing and performance evaluation.
Make necessary adjustments and improvements based on the test results.

Application areas
Mechanical equipment: Used to test and verify the strength and function of mechanical structures.
Consumer electronics: Verify the internal component layout and connection methods of electronic products.
Automotive industry: Test the structural strength and assembly methods of automotive parts.
Medical devices: Verify the functions and user interface design of medical devices.

Summary
Structural prototypes play a vital role in product development and can effectively verify the feasibility and functionality of the design. By reasonably selecting materials and processing methods, high-quality structural prototypes can be produced to ensure the performance and reliability of the final product.
