Quality Management

Foamed-semifinished product

1

Rest the newly foamed slab for 24 hours.

 

 

 

 

2

Semi-finished inspection

Appearance, length inspection.

Measure the height of the front, middle and rear end of the foam slab.

Measure the width of the top, middle, and bottom.

The light-colored anti-yellowing foam should be cut at the same places around 2 yards at the front and rear end. And take those pieces for testing

Inspection during cutting (appearance inspection, measurement, and testing)

 

 

Foam slab cutting

Tensile testing machine: After cutting the test piece with a standard die, use a tensile machine to test the tensile force, elongation, tear, peeling, etc. of the foam or cloth.

 

 

 

9

Compressive strength test: used to test the ability of the foam to recover after being pressed.

 

 

10

Standard light source color light: It is used to determine the degree of the color change of the foam under the standard light source, which is suitable for yellowing resistance.
