Mechanical Test

NG28 is able to provide a series of tests to identify and examine the performance and process properties of metal and non-metal material products.Through the test, we can help customers to evaluate the mechanical properties of materials and identify the weakness of materials (limit of use).

Mechanical Test

?    Service Background

1. Through the mechanical performance test, master its performance and achieve the best economy;

2. Mechanical performance is the main basis for mechanical parts design and material selection, providing guidance for customers to optimize design and scheme;

3. Assess whether the materials meet the corresponding standard requirements to protect the interests of customers in the trade;

4. Quality control of production process;

5. New material research and development.
