Adhesion of coating is the core testing index of coating quality. Traditional manual checkerboard knives rely on manual operation, which has some problems, such as uneven strength, skewed marking, large data deviation and poor repeatability, and it is difficult to meet the requirements of standardized quality inspection in modern factories. Chongqing Wanwei automatic grid tester strictly follows the national standard GB/T 9286, supports the grid marking of concave, convex, curved and planar workpieces, and can completely replace the manual grid cutter. It is the preferred equipment for upgrading quality inspection in production line and laboratory.

I. Core advantages of equipment
The equipment is optimized for industry detection pain points, and is suitable for mass production sampling inspection, R&D testing, customer factory inspection and ISO system audit. The core highlights are as follows:

1. Weight is stable at constant pressure: mechanical gravity exerts constant pressure, and the weight can be adjusted as required, so that the thin paint does not damage the substrate, and the cutting depth of the thick coating reaches the standard, with consistent test depth and high data repeatability;

2. Universal use of special-shaped workpieces: breaking the plane limitation of traditional equipment, curved surfaces and concave-convex workpieces can be automatically ruled and ruled, so as to prevent grid deformation and rating disputes;

3. Multi-spacing one-button switching: it supports three spacing of 1/2/3mm without changing tools, covering the whole scene of 3C thin paint, conventional hardware paint, thick plastic spraying and heavy anti-corrosion coating;

4. The parameters can be stored and traced: multiple groups of product parameters can be stored and called with one key, and the test data can be completely retained, which can easily pass the ISO system audit and customer inspection;

5. Ultra-low cost of consumables: it is suitable for common art blades in the market, which can be simply replaced after wear, and is convenient to maintain, and it is suitable for high-frequency sub-batch self-inspection in factories;

6. Fully automatic standardized operation: there is no need to rely on manual experience, the testing standards of all employees are unified, and multi-station customization is supported, which greatly improves the efficiency of batch testing.

Second, the industry-wide segmentation application scenarios
1. Automobile manufacturing
It is suitable for the detection of plastic interior parts, metal parts and electrophoretic spraying parts of automobile wheels, and can stably complete the standardized marking of various curved surfaces and irregular workpieces, meeting the strict quality control requirements of automobile enterprises.

2. 3C electronics
Adopt 1mm precise spacing, adapt to the plastic shell of mobile phone, computer, small household appliances, UV oil spraying, screen printing ink coating test, accurately detect thin coating, and adapt to all kinds of irregular curved workpieces.

3. Metal spray aluminum material
Suitable for inspection of aluminum alloy profiles, cabinets, door and window hardware, and plastic-sprayed workpieces. 2mm regular spacing is suitable for ordinary paint surface, and 3mm large spacing is suitable for thick plastic-sprayed workpieces with counterweight weights.

4. Research and development of coatings chemical industry
It can be used for formulation development, sample comparison and performance test of new coatings, with unified standards and traceable data, providing reliable data support for product iteration and performance optimization.

5. Building materials curtain wall floor
It is suitable for testing building materials such as aluminum veneer, curtain wall plate, exterior wall coating, floor paint, etc., and is compatible with flat and special-shaped curved workpieces. The test results meet the national standard and are suitable for factory quality inspection and engineering acceptance.

6. Daily products
It is widely used for coating inspection of plastic toys, kitchenware, lamps, craft gifts and other products, adapting to various irregular structures with concave and convex surfaces, and eliminating manual inspection errors.

7. Heavy industry anti-corrosion rail transit
For the detection of heavy-duty anti-corrosion thick coatings in construction machinery, rail transit and ships, the constant pressure of large weights and the spacing of 3mm can completely cut through the thick coatings and accurately detect the bonding strength of the coatings.

Third, general application scenarios
The equipment is also suitable for sample testing and experimental research in quality inspection laboratories of enterprises, third-party testing institutions and scientific research institutes of universities. It is a universal standardized adhesion testing equipment in the whole painting industry.
