Injection molding machine from WOOJIN BRAND NAME from SOUTH KOREA, Hydraulic, hybrid, Description detailed information about instruction, using machine Vì vậy mà hãy cứ bình tâm, em nhé Cuộc đời ta cũng như rượu vang vậy. Có những loại vài tháng là uống được, nhưng cũng có loại phải lưu giữ rất nhiều năm để đạt độ chín cần thiết. Điều quan trọng không phải là sớm hay là muộn, mà là đúng lúc. Bởi mọi thứ đều có thời điểm của riêng mình. Vị rượu ngon chính là phần thưởng của tháng năm. Cũng như câu chuyện về hai chú sâu kia. Sâu anh nằm trong cái kén cảm thấy bực bội vô cùng, nên cố vùng vẫy thật mạnh để mong thoát ra ngoài. Vùng vẫy ngày này qua ngày khác, sâu mọc đôi cánh bé. Nó lại cố ra sức đập cánh, đôi cánh dần lớn ra, cứng cáp. Và cuối cùng, sâu anh hóa bướm, rũ bỏ cái kén chật chội để bay lên cao. Khi đã thoát ra rồi, nó mới thấy sâu em vẫn còn mắc kẹt trong kén. Nó hăm hở lao đến giúp em phá vỡ cái kén và đưa sâu em ra ngoài.

The TB series is a new energy-saving hydraulic injection

molding machine that optimizes the mechanical structure

and control system for the servo pump system

Discrete hydraulic circuit for oil circulation, cooling, and filtering,

decreasing process startup time, maximizing process precision,

and increasing the life expectancy of the machine

Injection unit equipped with dual-pull nozzle touch cylinder,

Proportional/Integral/Differential valves,

& low friction mechanixm for improved precison and wear of nozzle

- Center-press platen and brake motor in clamping unit for increased accuracy & precision.

- High-rigidity frame

- Optimized mechancial design for greater clamping force in a smaller-sized machine.

- Stabilizing mounting feet reduce noise and isolate the machine from ambient vibration.

Mold

▲ On smaller-sized molds, clamping force concentrates at the corners of the mold. ▲ Regardless of mold size, clamping force dispersionand deflection is uniform across the entire mold face.

There is no interference during oil circulation

Oil - Tank

Use

Motor

Servo pump sytem reduces energy consumption

up to 80% vs traditional pump

Reduces heat generation & dissipation into hydraulic oil

Reduces oil cooling needs up to 25% compared to

traditional pump Produces less noise during machine

operation

- Oil-leakage protection

- Increase durability

3 Center press moving platen

Center-press toggle system is designed to apply well-dispersed force across the entire mold surface during clamping

High-lubricity tie bar bushings decrease friction and retain shape during clamp movements

- Evenly distributes clamping force on the mold

- Minimizes mold deflection

- Greater speed and stability in platen movement

4 Brake motor

The brake motor on the rear platen maintains the same position even after long and repeated use, eliminating the need to recalibrate mold height on even the longest production runs

- Maintaining set of clamping force

by preventing clamp slip phenomenon

Dedicated circuit for oil cooling/filtering maintains oil conditions with greater stability It helps to improve reducibility and reduce maintenance normally needed under typical molding conditions with integrated oil conditioning

By comparison, integrated oil circulation can bring contaminated oil into the tank through oil cooling/filtering and routine

operation, increasing the frequency of filter changes, adding

to component wear, producing additional heat, and contributing

to leak point formation

However, the newly designed oil tank & circulation system separates oil circulation from oil cooling/filtering through

a discrete pump, ensuring that unfiltered oil and filtered oil have

no contact during machine operation

Moreover, hydraulic oil can be conditioned while the process is idle or undergoing setup

Clamping unit

- Better process control and precision

- Reduce cooling & filtering time

▲ Closed-loop controlling cystem

▼ Dual cylinder injection unit

The dual pull nozzle touch cylinders are equipped

on both sides in injection unit providing greater stability and improved precision

By comparison, a single pull nozzle touch cylinder concentrates force at the bottom of the fixed platen, contributing to a loss of platen parallelism over the course

of routine use

▲ Single Pull Nozzle Touch Cylinder

Injection unit

1 Closed-loop system

3 Dual pull nozzle touch cylinder

2 Dual cylinder injection unit

Correlates system parameters with actual measurements, ensuring that all positions and pressures perceived by the controller are precisely those of the actual components and fluids

Ensures that there is absolutely no deviation between set parameters and actual measurements

- Enhanced control of injection back pressure by system feedback and self-regulation.

- Nozzle touch stability improves molding precision

- Faster reaction time of the screw during injection

- Provides an even axial force on the screw, reducing wear

- Greater process stability

- Minimize and cushion the impact

The dual cylinder injection unit is designed to provide

axial dispersion of force during screw traversal,

preventing wear against the barrel interior

High-responsiveness and minimizes molding defects

caused by uncontrolled pressure changes in melt flow
