INJECTION SYSTEM |
|
|
FEATURE: • APID temperature control, precise temperature control of barrel. |
|
| • Multi-injection speed and pressure and multi-level holding pressure settings, switch from the injection time, location, pressure control to ensure the quality of molding. • Multi-level back-pressure of pre-plastic and pre-speed are computer-controlled, anti-drooling and automated auto purge. • Expected to prevent cold-start function to ensure that the screw, barrel will not be harmed. Stability of the injection unit. |

SERVO ENERGY-SAVING |
|
|
FEATURS: • There is no extra energy consumption due to output volume changes according to load alteration. • In the phase od holding pressure,servo motor lowers rotate speed and consumes a little of energies. • In the phase of cooling,motor doesn't work and consumes no energy. • The noise is below 78bd.Servo motor has almost no noise huring no operation. • No constant flow pump and speed set motor overflow heating.When the temperature of hydraulic oil is lower,the cooling water is reduced greatly. |
|
|
According to different products,servo energy-saving injection molding machines will save 20%-80%energy and bring you prominent economic benefit. Is equipped with high performance servo motor controlling system,the machine's output power can vary in accordance with the loading changes. Which reduce energy consumption and noise.The motor rotates at lower speed in holding pressure stage,and doesn't work in cooling time. |

CLAMPING SYSTEM |
|
|
FEATURE: • Security doors fitted with hydraulic, mechanical and electrical interlocking triple safety device. When the safety door is open, the machine cannot clamp. |
|
|
• Automatic adjustment. The replacement of different mold, the parameters set by clamping force to achieve the automatic adjustment. • High-precision electronic detection device, multi-stage control of opening stoke, speed and location, location accuracy. • Arch splint piece of the tail plate use the finite element analysis. It features as light weight, high-intensity, and high- rigidity. • Flexible core programming control, and independent hydraulic pump station to provide power. |
|
| LUBRICATION SYSTEM | |
|
The following should be focused on when using the lubricating oil:
|
|
|
• Proper lubrication will lengthen the service life;on the contrary ,poor lubrication will result in the wear and heat of parts.The clamping unit of the machine employs auto central lubricating device,and the other necessary moving parts have grease nipples for lubrication. Lubrication oil is an important factor of the machine.No operation without lubricating,otherwise the equipment will be seriously damaged. |
|
| SAFE SYSTEM | |
|
• The safety devices include safety door and locking-self mechanism.All safety doors are very important to avoid personal to damage by splashing melted material and prevent person from dangers zone.The locking-self mechanism will stop all damage action at any door opening. • The safety door limit switch serves to interrupt the mold closing.When the safety door is open,limit switch has been activated to brek the circuit.Its dual circuit control functions of Normally closed and Normail open can stop the motion of the machine. |
|
In case of any accident or error in the process of operation,first press the emergency stop button (the red projectied one on the lower right corner of the screen),and then turn off the main power supply switch.Find out the causes of fault and do not start the machine until all faults have been rectified. |

about us
HC series plastic injection molding machine has moving platen featuring box type bridge structure and full-connected rear high-rigidity mold platen. Through finite element analysis, it can prevent deforming of mold platen, resist against fatigue, have high repetition accuracy, distribute mold closing force uniformly, greatly increase mold's service life and reduce the molded parts cost.
Clamping unit:
1. Internally-rolled 5-point double toggle mold clamp structure, greatly increases rigidity and precision of the mold clamp unit.
2. With box type bridge structure, moving platen, and high rigidity continuous rear platen reinforced through finite-element analysis, we guarantee that the mold platens are not deformable and are durable.
3. The tie rods are made of high quality structural alloy steel plated with hard chromium, with high mechanical strength and fatigue strength.
4. Provided with low-pressure mold protection device.
5. Multi stages controlling of mold clamp pressure, speed and position.
6. Mold thickness adjusted through ring gear driven by hydraulic oil motor.
7. Several hydraulic ejection modes.
Injection unit:
1. Use of double guide posts and dual-cylinder balance injection device, guarantees that balanced and uniform forces are applied on the screw during injection and moving forward.
2. High quality alloy screw nitride or with chromium plating, and nitride barrels, are protected against corrosion and fatigue, which greatly increase their service life.
3. With fine adjustment of nozzle centering.
4. Screw preplasticizing driven by high torque hydraulic motor device.
5. Multiple injection speed, pressure and position settings.
6. Special screws and barrels are provided according to different properties of engineering plastics to ensure the molding quality of finished products.
Lubricant unit:
1. With use of volumetric electrical lubricator, automatic centralized lubrication and uniform oil distribution in the pipeline, the machines have high lubrication efficiency and long toggle life. Hydraulic unit:
1. Well-known oil pump and control valves in the world are used, to execute accurate controlling over the force, speed and direction of hydraulic mechanism and ensure the accuracy, reliability, stability and durability of the machine.
2. Control system of the constant displacement pump ensures steady outputs and high response.
3. Main hydraulic elements and seals are international well-known brands.
4. The pipelines are arranged more reasonably and better, and thus ensure easy maintenance.
