Copper Alloy 2500Ton Brass Cold Chamber Die Casting Machine

Features

1. The mold platen material is made of nodular cast iron and special alloy material. with good ductility and can better absorb the impact force of injection; High surface hardness, effectively reduce the die extrusion and impact marks. The formwork adopts thickened design to ensure that the formwork surface is not easy to sag and fracture during long-term use.

2. The movable mold platen adopts the rib plate structure design, which not only enhances the strength of the middle plate from the structure, but also solves a series of problems existing in the suspended thimble structure commonly used in the industry.

3. All moving joints of the machine shall be provided with alloy steel bush, and with liquid nitrogen cold charging process, the joint pressure shall be uniform, so as to effectively extend the service life of the machine.

4. According to the design standard of imported machine, medium frequency processing is adopted for the thread of tie-bar, which improves the hardness and wear resistance of the thread pair, and solves the common problems of mold adjustment and thread strain in the industry.

5. The machine base adopts integral I-shaped steel structure and adds steel beam support structure. Combined with heat treatment process, it has better rigidity and is not easy to deform, effectively maintaining the accuracy of long-term use of the machine.

6. The special alloy material and heat treatment process are adopted for the tie-bar, and the vertical and horizontal two-way stress release system is added to ensure the stable clamping force of the whole machine and prolong the service life of the tie-bar.

7. High performance injection system, with active injection and direct pressurization structure, equipped with high-performance energy storage system, optimizes the oil circuit of the injection system, reduces the loss in the process of energy transfer, the injection acceleration reaches 60g, and greatly improves the stability and repeatability of key parameters. In addition, the injection system is equipped with automatic energy storage function, automatic calculation and matching function of energy storage pressure, pressurization failure alarm function, nitrogen leakage alarm function, automatic unloading function, etc.

8. Cartridge valve opening adjustment mechanism, self-developed cartridge valve opening adjustment mechanism, solved the technical problems of adjustment difficulty in the industry.

9. The appearance design led by the world's leading industrial design team has provided innovative design for nearly 2000 customers around the world, with grand and practical appearance.

General technology

Servo Motor Energy Saving System /Oil Cooling System(option)

1. High efficiency and excellence in energy saving

The die casting machine automatically adjusts the flow pressure based on the computer setting. The overall energy saving effect can reach 45%~75%.

2. Low noise

Noise during normal operation less than 65dB, to achieve quiet operation and improve the working environment.

3. High speed response

The overall system dynamic response time is less than 50ms, and the production efficiency is increased by 5% to 7% over the ordinary models.

4. High-precision control

The PID adjustment of the system flow and pressure by the oil-cooled servo driver makes that the repeatable precision of the entire oil system is controlled within 0.3% to ensure product quality.

5. Increase of service life

The double closed loop of flow pressure makes the machine run steadily and with high repeatability, greatly reducing the strike, relieving the wear of various components and prolonging the service life.
