Cupping Tester

The CUPINTEK Embosser allows evaluating the adhesion and flexibility of coatings on aluminum and steel through a controlled test according to ISO 1520.

What is the CUPINTEK Embosser?

The CUPINTEK Embosser is a manual device designed to measure the resistance to deformation of paints and coatings on aluminum and steel, complying with ISO 1520. This test is essential in quality laboratories as it allows evaluating both the adhesion and flexibility of the coating when subjected to controlled embossing.

What is the purpose of the manual embosser?

The equipment simulates the deformation of the coating using a 20 mm sphere that presses the sample until cracks appear. During the test, the depth reached is recorded accurately, allowing analysis of:

• Appearance of cracks due to stress.
• Adhesion of the coating to the substrate.
• Mechanical behavior of the material under bending or stretching.

This method ensures reliable results for quality control laboratories and coating development.

Advantages of the CUPINTEK Embosser

• Smooth and constant advance: Mechanical design requiring minimal manual effort.
• Precise speed control: 0.25 mm per turn, complying with ISO 1520 (0.2 – 0.3 mm/sec).
• High-resolution digital measurement: Depth measured with 0.01 mm precision and immediate reading.
• Ergonomic design: Comfortable use even in repetitive tests.

Frequently Asked Questions (FAQ)

What types of materials can I test?
It can be used on aluminum, galvanized steel, and other coated metals, simulating deformations that occur under real bending or stretching conditions.

How is the depth of the embossing measured?
The equipment includes a digital display with 0.01 mm resolution for immediate reading.

What advantages does this embosser have over automatic models?
Although manual, its controlled advance, digital precision, and ergonomic design make it competitive against more expensive and complex automatic models, especially for laboratories seeking efficiency without complications.
