Can avoid the oil leakage. Because using Servo motor, the oil temperature can be lower. 2. English and customer country local language, bilingual operation interface, easy to operate. 3.Can save 50% - 70% electricity energy. 4.Parameters and Speed can be adjusted on the touch screen, easy to operate.(Machine without servo system, speed can not been adjusted.) 5.Can be 3 to 5 years longer service life than the common machine. it means,if common machine can service for 10 years, then machine with servo, can use 15 years. 6.Ensure safety and easy to know error,easy to do after service. Because of Automatic alarm and auto troubleshooting system.  7.Very easy to change mold, shorter time of changing mold. Because it have memory function,if use the original mold, do not need to adjust parameter again, 8.Very quiet , do not have noise. 9.Much stable than common machine. 10.Much high precision than common machine. l We could supply not only custom machine,molds,robot arm(manipulator),auto feeder process technology, and other relative machines but also a full production line service. l The main components are imported from Japan and Taiwan . So the quality is near the Japan production, but the unit price is lower than  Japan production. l Our factory have specialized in independent development and producing hydraulic press for over 20 years. So the product is stable and high quality. l Machine body, we use bending structure , much stronger than the common welding structure . l Oil pipe, we use Clip-on structure , much tight than common welding structure. Prevent oil leakage. l We take integrated oil manifold block, much easier to check machine and repair machine. Quality Control All of the hydraulic presses in our factory have passed CE,ISO,SGS,BV certificates. Technical Features 1.With servo system, save energy 60%, 0.02mm precision, Speed adjustable. Customer local language on touch screen, 20 sets data saving function. 2.Using advanced hydraulic system allows few malfunction. High reliability and small reversing impact. 3.Four columns are made of high-strength alloy steel with hard chrome plated surface and good abrasion resistance. 4.Key hydraulic electrical parts come from famous brands of Germany, United Stated and Japan.Quality is guaranteed. 5.The continuous circulating oil cooling system lowers the oil temperature during machine running. Applicable Scope 1. Deep drawing for metal and nonmetal parts, and other processing operations like pressing and punching. Such as tableware, kitchenware, metal shell of motor and electrical appliances, automotive sheet metal drawing parts, cover bottom plate and lighting parts, etc.
