Medium and large size Hydraulic Plastic Injection Molding Machine
EH Series (180~750 TON)
Medium and large-size Hydraulic Plastic Injection Molding Machines ranging from 180ton to 750ton has the mainly hydraulic system configures an Electro-hydraulic proportional system to control the oil flow and pressure. It has responsive and high-consistency features. Via the Lvdt spool receives the feedback signal and modifying output, lets the users get a hydraulic pressure closer to the actual situation, and helps the users grasp the control of injection parameters. The power resource is from a double fixed vane pump. The main hydraulic system can provide a high-flow source via pumps' confluent, which gives an advantage to booting up the speed of the machine.
The traditional-hydraulic system has two features, one is high-pressure resistance, and second is it can provide a long holding time. So the traditional injection machine is more suitable for making thick parts, transparent parts, products that require a smooth surface, or materials that need high-pressure holding.

Our Advantage
- Hydraulic Plastic Injection Molding Machine is the best solution for engineering plastic like PPS, PPSU, PPI, PEI. According to the feature of the electric-hydraulic controlling system, the pressure output could extend a long time, it does an advantage for a product that needs a long holding pressure time.
- The platen uses the FCD-600 spheroidal graphite cast iron could achieve 600 ~ 750 N/mm² tensile strength not easy to bend or deform.
- The toggle automatic centralized lubrication system, always keeps the toggle and copper bushing parts lubricated to increase the life-time.
- Dual injection cylinders mechanism provides high-pressure and high-speed injection, match with the high response valve upgrade the performance of injection.
- The Mold Adjustment Mechanism with sturdy gear and high torque hydraulic motor has high strength and low clearance, which reduces adjusting time and increases accuracy.
- Mold Adjustment Motor with Brake Unit always keeps the platen in the same position prevents to cause the flash of the products.
- The s-60c high carbon steel slide matched the roller bearing reduces the friction and brings smooth during mold opening and clamping.
- Mold open/clamping switch is controlled by a proportional solenoid valve increase the stability of the platen location point.

Small Size Hydraulic Plastic Injection Molding Machine
EH Series (50~140 TON)
The 50ton to 140ton Small-size Hydraulic Plastic Injection Molding Machine comes with an electro-hydraulic control system by the Rexroth solenoid and proportional pressure relief valve (both with Lvdt). The high-response hydraulic pressure and flow control system can quickly changeover to every injection stages command given by the user is needed. The hydraulic power resource is from the induction motor coupled with a vane pump, it is more capable of producing long hold pressure time (more than 60sec) products.

Small Size Hybrid Plastic Injection Molding Machine
EH-DS Series (50~140 TON)
Small size Hybrid Injection Plastic Machine range from 50ton to 140ton equips the servo energy saving system, which achieves an outstanding energy-saving effect. The Hydraulic system with a rapid response and pressure output linear feature, easy to reach every requirement given by the user. Our Injection Machines can provide stable pressure when a high flow rate is required during the production. It saves energy during the low pressure output and the product cooling. Comparing with the conventional hydraulic system, it saves 60% energy consumption. It has a perfect pressure curve repeatability, and still keep the advantage of conventional hydraulic system, that has the ability to keep the pressure at 140kg/cm2 at least 30 sec. with low oil flow, it gives a huge competitiveness of thick products to prevent shrink, bubblers, jetting, etc. If you need more detail of product catalog, please reach out to us.
