Ink Abrasion Test Procedure

Ink abrasion tester simulates a similar environment to test the rub resistance on printed materials.It is used to analyze the life of label by creating actual environment of application to evaluate abrasion resistance of surface coating layer of printed material.inks rub resistance tester simulates the actual working environment of product and helps to identify the quality and printing method to be used for printing of label based on application of product and its working environment.

Ink abrasion test, also known as Ink Rub test, is to measure the ink resistance against rubbing on packaging materials, professionally designed for abrasion resistance of surface coating layers of printed materials, e.g. ink layer or photosensitive (PS) coating. This instrument could effectively analyze the problems of poor abrasion resistance, ink layer falling off, lower printable force and poor hardness of coating layers of printed materials.

The tests are performed according to the following procedures.
1.Cut one piece of specimen from the provided sample and then fix the specimen in the test plane of the instrument. The size of the specimen should be 230mmx50mm.
2.Use a reflection densitometer to measure the density of the ink layer on the surface of the specimen.
3.Fix the rubber pad on the test block and then place it onto the specimen.
4.Set rub times and then start tests. The rubber pad with test block will rub on the specimen surface until the preset rub times are completed.
5.When tests are finished, the density of ink layer will be measured by reflection densitometer and the abrasion resistance of the specimen will be calculated.

Multi-Functional Scratch tester For automotive interior materials

Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method). Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured. Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consumer goods. Scratch tester is used in various applications such as

FMVSS 302 With Horizontal Flammability Tester

FMVSS 302 is one of the most important to crash survivability. This standard not only designates acceptable flammability characteristics of materials to be used in vehicle interiors but also outlines specifications for testing these properties and interpreting their results. By comparing their findings against the desired burn characteristics, auto manufacturers and parts suppliers can ensure their interior materials are approved for use. Test instruments : Horizontal Flammability Tester ; Test Procedure of Horizontal Flame Tester ： a.Mount the specimen so that both sides and one end are held by the U-shaped frame, and one end is even with the open end of the frame. Where the maximum available width of a specimen is not more than 51 mm, so that the sides of the specimen cannot be held in the U-shaped frame, place the specimen in position on wire supports as described in S5.1.3, with one end held by the closed end of the U-shaped frame. b.Place the mounted specimen in a hori

Zipper Tester, Slide Fastener Reciprocating Tester

The Zipper Tester, also known as a Slide Fastener Reciprocating Tester, is a specialized device used to test the durability and functionality of zippers or slide fasteners. It is commonly used in the textile, garment, and bag manufacturing industries to ensure the quality of zippers used in various products. The tester simulates the repeated opening and closing actions that zippers undergo during normal usage. It evaluates the zipper's resistance to wear and tear, as well as its ability to withstand the repetitive movements and forces applied during regular operation. The Zipper Tester typically consists of a testing chamber or fixture, where the zipper is securely clamped. The tester applies a controlled reciprocating motion to the zipper slider, repeatedly opening and closing the zipper according to predefined parameters, such as cycle count and speed. During the testing process, the machine measures various performance parameters, including the force required to open and close t
