Company Profile

LIS Automatic Controlled Co., LTD. was founded in 1979 in the city of Taichung, the capital of the machine tools industry of Taiwan. For the past thirty years LIS has been the sole designer and manufacturer of hydraulic units for many machine tools manufacturers, both domestic and international. Our product lines have expanded and have become more innovative to meet the demands of ever-improving metal cutting, die casting, and plastic injection tools etc.In 2006 we established the PolarJet CNC Solutions, Inc., which specializes in the production of high-pressure coolant systems to help customers solve difficult machining problems.After years of effort, we have developed a series of products that are available for use in different types of machine tools.We will continue to innovation and move forward for customer priority position and customer goals , to create a win-win situation with our customers.

LIS AUTOMATIC holds the quality commitments to our products, with perfection and responsibility. All products are extensively tested before shipment. POLARJET is assembled with high-quality components, to ensure the durability and reliability of the systems, which also operate according to the customers' requirements.
In the wake of the industrial automation, high speed and intelligent development, the application of the high pressure coolant system is more important, which focusing and penetrating the vapor barrier through the cutting coolant, reducing the high temperature while cutting the workpieces, improving the tool life and the surface accuracy of the workpieces which may reducing the finishing process of deburring.
