Advantages of our machine:
l With Servo system
YIHUI Hydraulic press with servo system,can bring you 10 kinds Advantages as below:
1. 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.
All of the hydraulic presses in our factory have passed CE,ISO,SGS,BV certificates.
1. Using Taiwan advanced hydraulic system, more steady, safer and more reliable.
2. Pressure, stroke and pressure keeping can be adjusted according to processing requirement.
3. Four columns are made of high-strength alloy steel with hard chrome plated surface and good abrasion resistance.
4. The moving bolster and worktable are equipped with optional ejecting cylinder, which meets different ejecting requirements of different products.
5. Digital control is achieved with PLC programming circuit design and touch panel operating system.
1. Cold extrusion molding and stamping for auto parts, LED heat sink and hardware tools, etc.
2. Shallow stretching and molding for metal and nonmetal parts.
High Speed Hydraulic Press YH-FAST System
Extruding Height Over 50MM
From Fast to Slow Speed
Cylinder automatically switches pump for pressurizing & shaping.
Traditional hydraulic oil system is powered by motor and pump. When the tonnage is confirmed, the faster pressing speed it is, the more motor power and pump flow are required. By analyzing the required oil flow each running step needs, we storage the additional energy generated during slow pressing via electromagnetic valves to the accumulator. And during fast pressing, signal will be transferred to the electromagnetic to start the accumulator. Then additional energy will be released to supplement the fast pressing. This is achieved by adding multiple sets of energy accumulators. Therefore we improve the pressing speed and production efficiency.
Improve pressurizing speed of hydraulic press.
