Scratch 5.5 Machine

製品紹介：

The Scratch 5.5 Machine is a scratch and scratch test instrument for macroscopic scratches. It is a research-grade tribology instrument for polymers, coatings, films and bulk materials that explores scratches, scratches and other surface properties in a rigorous and meaningful way.

Common industrial applications include:

Automotive, Aerospace interiors, exteriors and coatings.

Food packaging and labeling.

Aerospace wear resistance.

Scratch resistance and scratch resistance of consumer electronics products.

Home and furniture scratch resistant.

Downhole coating resistant to scratches.

Scratch resistance and wear resistance of industrial automatic production line.

Multiple test modes:

Rise, fall and dead load scratches and scratches. Reciprocating （wear） and indentation. Multiple industry standards can be replicated, including ASTM D7027-05, ISO 19262-12, ASTM D5178, TAMU/Avery-Dennison Mar, Ford 5 Fingers, Erichsen Cross Hatch, Pencil Hardness （dead load）， Volkswagen PV3952, GM 14688-A-10N. Surface Mechanical Systems is a member of the D20 ASTM Committee and works with the PTC SCRATCH Consortium and other industry partners to help develop and promote rigorous tribology standards.

Technical parameters:

1.4 axis instrument

Normal and tangential loads （up to 400N）， micron depth resolution, high resolution tangential data up to 2000 samples per second.

Normal load: 600N, accuracy 0.05%.

Normal load: 100N, 200N, accuracy 0.25%.

Depth: 50mm, accuracy: 5 microns.

Puncture test （optional）

Up to 2,000 data points per second, in place

High speed, high load

2.Scratch 5.5 machines apply real-world loads at macro speed. Up to 400mm per second at loads of up to 400n.

Speed: 1 -- 400mm /s, programmable.

Load: 1 to 400N, progressive or constant load, programmable.

3. Programmable progressive load curve

The G5.5 machine is fully programmable from 1 to 400mm /s, with loads from 0.5 to 400N （depending on configuration）。 Each test can be run as a progressive load, using any valid load range as a starting and ending point. You can dial specific strain rates to test specific material properties.
