QMS

In our production process, we have a number of measures to ensure the quality of our products, briefly described as following:

QC

From the beginning of production, the material of acrylic will go through dust blow off phase to clean impurities and black spots in the plastic raw material. 

INJECTING / BLOWING: (In process QC)

Our quality inspector will examine the containers as they come out of the injecting or blowing equipment. We will remove any packaging that has bubbles, black dots, or scratches from the production line to recycle room.

DECORATING / PRITING: (In process QC)

At the decoration stage, we will examine the product outcome after each procedure such as spray painting, hot-stamping, silk screen printing etc. for imperfections, wrong position, or color mismatching. If there’s any visible problem on the parts, it will be discarded.
