Coil insulation treatment under vacuum, the insulating oil can rapidly and evenly, completely penetrated into every little pores and voids of the coil, and the smooth surface. Disposal of product by vacuum insulation, the insulation performance can be greatly improved, reducing the product's power consumption, noise and vibration significant effect temperature rise, etc., to improve product quality, extend the life of the product have a good effect, so the use of vacuum impregnation paint is unmatched radical dipping process selection and improve the market competitiveness of equipment.
　　Use Hanjin shorten the soaking time than traditional dipping process a few times, but also shorten the time and data loss in drip process, directly reduce production costs, improve product quality and market competitiveness. Thus, Hanjin, Hyundai Electronics industry high standards and high requirements necessary production equipment. Products to enter the international market competition is essential production equipment.
　　Content mechanical engineering
　　Broad service areas of mechanical engineering and multi-faceted, any use of machinery, tools, as well as the production of energy and materials sectors, need mechanical engineering services. Generally speaking, modern mechanical engineering in five service areas: the development and delivery of energy conversion machinery, provide for the development and production of various products, machinery, research and provision of services in a variety of machinery, the development and provision of family and personal life Application machinery, research and offers a variety of mechanical arms.
