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.
Trang 1The TB series is a new energy-saving hydraulic injection
molding machine that optimizes the mechanical structure
and control system for the servo pump system

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.

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
Trang 3▲ 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

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
