Answer the common selection and use questions of Chongqing Wanwei automatic checkerboard, including concave-convex surface detection, marking spacing, consumables cost, ISO factory inspection, multi-station customization and other questions, and take you to understand the advantages of national standard automatic paint film checkerboard equipment.

Chongqing Wanwei automatic grid tester conforms to the national standard GB/T9286, the weight is automatically marked at constant pressure, and the spacing of 1/2/3mm can be adjusted. The cost of consumables is low, and it is suitable for the adhesion detection of paint films in automobile, 3C electronics, plastic spraying and anti-corrosion industries, replacing manual grid knives, and the detection data is stable and traceable.

Chongqing Wanwei Instrument WV-603-500 fully automatic carton compression testing machine is specialized in testing the compression performance of corrugated boxes, plastic buckets and other packaging containers, which conforms to national and international testing standards, has high precision and stable operation, and is suitable for box compression and stacking testing in packaging, logistics and food industries.

Chongqing Wanwei Instrument has newly launched the five-axis linkage automatic 100-grid testing machine WV-BG-02 (CNC). In the paint and paint coating industry, the coating adhesion is the core testing index to judge the durability and appearance stability of the finished product. Traditional manual checkered knives rely entirely on manual operation, with uneven strength, irregular grid, poor detection repeatability and low efficiency of batch production line detection, which is difficult to meet the requirements of standardized quality inspection in modern factories and compliance testing of third-party testing institutions.
