While much brain work originated at the Head Office, the actual milling is done in the two sites at YunLin Industrial Park.
There are two Catis manufacturing plants, namely Plant-1 and Plant-2 located a stone throw from each other. Plant-1 houses the administrations, product development and testing, tooling molds design and engineering, plastic injections, assembly and delivery. Inventory, heavy machinery work and thus noise are taken care of at Plant-2.
