Quality Inspection Center

Establish strict quality control procedures

Automatic Insertion Force test Machine

By applying a certain force to the connector plugging and unplugging process to simulate the plugging and unplugging load of the connector in the actual use process, to assess the reliability and stability of the connector in use.

Salt spray Test Machine

By generating specific environmental atmospheres, such as salt spray and sea spray, the connectors are exposed to high concentrations of corrosive substances, to assess whether the surface coating and finish of the test product protects the substrate from corrosion and whether it maintains its proper function over time.

Precision Testing Machine

For measuring and detecting various parameters and physical quantities, ensuring high accuracy and stability of products.

Capacitance Tester

Determine if this connector is working properly by testing the capacitance value between the two connector pins. In this way, the connector can be tested quickly and accurately to ensure its reliability.

High Precision Secondary Image Measuring Instrument

By projecting the object to be measured in the imaging system, the image is recorded and digitized to obtain parameters such as size, shape and position of the object to improve production efficiency.

Electric heating constant temperature drying oven

Electric Heating Constant Temperature Drying Oven

It is used for testing thermal properties parameters such as coefficient of thermal expansion, thermal conductivity, and heat capacity of materials, as well as for quality analysis and purification of materials. It is an indispensable equipment.
