Quartz Factory
Cornerstone Quartz Factory was established in 2003 and currently operates 14 pressing lines. We use YONGJIN brand presses and gas-heated laminating curing ovens to ensure the density and flatness of its products. The factory also has 4 KEDA brand polishing lines, which equipped with eight plus four grinding heads on the back for thickness control, ensuring a smooth and even back surface.
The factory primarily produces over 100 models of quartz stone slabs across five major series: Crystal, Fine Grain, Pure White, Fish Belly White, and Multi-Color. It has recently launched a new heat-transfer printed quartz stone product, featuring a richer variety of patterns and receiving an exceptionally positive market response.
