DAOBEN VR-E3 SERIES MOULDING MACHINE

VR-E3 Plastic Injection Molding Machine Features

FURTHER EFFICIENCY IMPROVEMENT:
1. Newly upgraded power, increased glue injection speed by 15% – 25%
2. Newly optimized screw design, significantly increased screw speed, and further improved plasticizing ability by 5% – 10%
3. Increase the overall dry cycle by more than 5%

FURTHER ENERGY-SAVING
1. Adopting control pipeline and oil valve adaptability optimization design to reduce pressure loss
2. High-precision wire rails are used for injection and glue injection, and low-friction oil seals are used for oil seals to reduce friction resistance in our moulding machine
3. Adopting a new generation servo system paired with a gear pump, high speed, low energy consumption

FURTHER STABILITY
1. The rigidity of the locking mechanism is improved, the distribution of locking force is evenly distributed, and the central force is strengthened to enhance reliability and durability
2. Comprehensive optimization of the shooting platform structure and plasticizing components

injection device

INJECTION DEVICE

The locking mechanism of our injection moulding machine is comprehensively optimized, with a central strong support two-plate structure, a high rigidity locking head plate, and a locking two-plate structure design to enhance the overall rigidity of the locking mechanism. The entire series is equipped with a T-shaped groove+code mold hole combination template, which not only facilitates the installation and removal of molds, but also improves the overall rigidity of the template.

New shooting platform structure upgrade:

1. Injection line rail structure: reduces movement friction resistance, captures injection accuracy, and improves plasticization efficiency

2. Double injection and transfer oil cylinder structure: reduces movement sequence friction resistance and facilitates maintenance and operation

3. Self-lubrication and cleaning of glue injection and transfer equipment: self-lubricating for over 8000 kilometers, reducing oil pollution to the workshop and environment

CLAMPING UNIT

1. The design of the strong support structure at the center of the second board reduces template deformation and achieves an even distribution of locking force; Using lower clamping force can also reduce the deformation of the mold cavity size, improve the forming accuracy of the product, and save energy.
2. Structural optimization of locking head plate and locking tail plate, with increased rigidity and minimal shape change.
3. The unique design of the guide pillar unloading groove, guide pillar and guide pillar nut thread pitch diameter significantly reduces stress concentration, achieves zero failure of the guide pillar and guide pillar nut, and improves reliability.
4. Integrated injection support bracket: Adopting an integrated injection support bracket, the support point is moved forward, and the injection head plate is fixed to improve the stability of the injection part

hydraulic unit

HYDRAULIC UNIT

New hydraulic oil circuit design: Optimize oil circuit flow design, reduce pressure loss, and be more energy-efficient: optimize hydraulic principles and valve plate pipeline flow channel design, reduce oil circuit pressure loss, and be more energy-efficient.
Low-friction oil seal: Reduce frictional heat and energy loss.
Further response: Spray glue and melt glue have high response speeds and a wider process range.
Standard CNC backpressure: Adopting CNC back pressure method for more convenient adjustment of adhesive back pressure.
Further power improvement: Increased power, strong power, and improved glue injection speed.

CONTROL SYSTEM

1. Fully upgrade the electronic control system and adopt the Mengl MS series controller;
2. New control panel design and page design;
3. Upgrade the screen to a 12-inch screen;
4. The control unit CPU adopts Cortex-A55, a 4-core/2GHz CPU, with a control cycle increased to 0.2 ms recording speed, fast response speed, and high control accuracy;
5. Upgrade mold parameter storage to 1000 sets;
6. Support multiple sets of action pressure velocity curves (closing and opening the mold, firing, pressing, etc., but black requires special agents);
7. Closed mold positioning control, open mold positioning control, injection positioning control, fixed mold positioning control;
8. Equipped with MES system process parameter reverse writing function (optional)
