Retractable tie-bar construction is the most popular trend for middle to large plastic injection molding machine ,which has uncomparable advantages in design.Stress-equilibrium feature is introduced which guarantees the life span of the bar.
Tie-bars are fixed at moving mold platen and two diagonally long-stroke smaller diameter diameter cylinders provide quick platen movement,third platen is no longer required.Two-platen design reduces the span length of clamping unit.NHTH series is the best choice for customers to replace their old machines with larger claming force and with less space occupied.
Two-platen construction shortens the tie-bars length and weight.Higher stiffness of spheroidal box-type cast iron platen.
Stress equilibrium structure of high-pressure champingHigh pressure clamping loading is evenly distributed on threads of tie-bars and no critical components to counteract the loading,marking the machine more stable and durable.
Multi pumps combination to reduce the power consumption and enhance flow matching characteristicCylinders of diffent sizes for platen moving and high pressure clamping to reduce hydraulic oil required.
Linear bearing and large footprint on moving platen to support the weight of large mold.Some movements can be controlled simultaneously to reduce the cycle time
Tie-bar is separated form fixed platen after opening the mold area.Automation handing devices for example robot arm ,can pick up the roducts form the mold at the horizontal direction.All the parts are clear and accessible on the clamping side ,which is easy to inspect and maintain.
Two platen reduces length and weight of machine ,it means muchi easier to load and less transportation costCustomers could choose three-phase asynchronous motor and servo drive with muliti pumps conbination
Applications:
It is manily applied in large precision product with deep cavity, including auto parts, pallet,garbage can.

Competitive Advantage:
1. Independent technological patent such as retractable tie bar and rotating locking structure, safety and reliable.
2. Direct locking structure makes tie bar stress evenly and have a long working life.3. Box type platen with little deformation and high rigid.
4. Super large opening stroke and mold space for many kinds of mold5. Different dimater of cyliner is for high speed closing, opening and high pressure closing. Less oil and energy saving.
6. Tie bar is sperated when molding opening and is easy for mold installation.20% space saving than three platen machine
