QC System

Under the control of ISO9001, ISO14001 and ISO14025, from material to the final product, each piece is processed through 49 working procedures and each procedure is controlled strictly by certain producing data. Especially for 
the procedures of kiln dry skills, environmental climates and piece checking, which promise our floor with a stable and high quality.


PC BY PC CHECKING

MC(moisture content) check. Before the KD board go into the T&G(Tongue and Groove) processing workshop, we will classify the KD boards according to the different MC level. This procedure promises all the classified KD boards is at the same MC level. At the same time, the two faces and four sides will be checked. Any defects board will be put away.

The twist surface check, before T&G processing, the workers will check the surface and put away the defects board.

Thickness check and surface check after T&G processing.
Processing defect check at the same time, classify the T&G board according to the natural color variation. Make the color in most uniform.
Sanding check before UV coating. Check the surface and thickness.
UV product line check, put away the defect UV coating product.
Final product color classified secondly. Make the final packed products color in most uniform .
Advanced kiln dry skills-key factor of final floor with a stable condition.

Advanced internal kiln equipment with experienced dry skills 
Drying the AD board according to the different places climate requirement. Making the MC more close to the local climate requirement. 
Drying the AD board according to the different species. Different species need different way (such as; time, temperature , Moisture etc.) to dry. 
Before further processing, the dried boards just after taking out from the kiln need a stress-relief period. Different species need different stress-relief time. Then the AD board turned into KD board. The stress-relief period is very important for the stability of the floor.

Test and record at the quality control center
We select the final products randomly form UV coating line for testing the impact resistance, wear resistance, hardness of surface, adhesion, scratch resistance, MC and dimensions. And then, we make a record for all the testing. If any item can't meet the requirement, the quality control center will immediately inform the workshop to improve.
