Conjoined coating equipment is based on the strength of the source to ensure high quality, high efficiency, and high stability, and launch a more perfect vacuum coating mass production solution. Continuous coating can prevent the coating chamber from being exposed to the atmosphere, which ensures the stability of the coating process and also saves pumping time and doubles the production efficiency. Conjoined equipment through the simplified and optimized configuration of the vacuum unit, the energy consumption of the conjoined equipment for plating the same number of products is about 60% of the energy consumption of the single equipment, effectively saving energy, reducing costs for enterprises, and greatly shortening the equipment investment payback period.
