BIG FIVE ADVANTAGES OF QGM AUTOMATIC BLOCK MAKING MACHINES
Our machines, with harmonic cooperation between mechanical, electrical and hydraulic machines functions, guarantee a reliable and high output production of concrete products.

1. Use Germany Siemens PLC control system and Siemens Touch Screen, use Schneider and Omron relays and contactors
A. Siemens PLC, with great adaptability, guarantees the stability and reliability of the machine.
B. Visualization touch screen, with easy operation
C. High-quality electrical components from Schneider and Omron.

2. Use Frequency Conversional Control Technology, which controls the block making:
A. Frequency Conversion Control: Guarantees the precise and parallel movement between tamper head and mould, protects the products from transfiguration; Increases the production rate by improving the vibrating efficiency
B. Controls the instantaneous start and stop of the motors, to protect the motor from over-heating caused by constant working
C. Power saving: 30%;

3. Use Double high-dynamic Proportional/Directional Valves to automatically adjust the oil flow and pressure
A. Buffer the hydraulic cylinder, to protect the cylinder from damage caused by inertia;
B. Guarantee production stability; .

4. 360° Multi-Shaft Rotating and Compulsory Feeding
A. Speedy and rotating feeding, with uniform mixing, to make sure that the density and intensity of the products are guaranteed
B. This uniform feeding is applicable for different kinds of raw materials and moulds;

5. Use heat treatment on moulds and main parts of the machines:
A. Heavy duty machine structure and wear resistant moulds;
B. The hardness reaches up to HRC 52-58
C. Greatly improves the using lifetime of the machine by 50%.

Technical Features
1) Uses Germany Siemens PLC control system and Siemens Touch Screen.
A. Visualization screen with easy operation;
B. Is able to set up, update and amend the production perimeters, to maximize the production output;
C. Dynamic display of the systems status, automatic trouble shooting and warning notice;
D. Has automatic-locking function, avoiding mechanical accidents caused by operational mistakes;
E. Is able to troubleshoot the machinery via teleservice.

2) Uses high-dynamic proportional and directional valves, which automatically adjust the oil flow and pressure as per specific working requirements, to buffer the hydraulic cylinder when working; Uses integrated high-pressure and soft oil pipes, with easy installation;
3) Uses multi-shaft rotating and compulsory feeding, which greatly improves the density and intensity of the blocks, and reduces the feeding time as well;
4) Integrated structure of vibrating and moulding platforms, which reduces the weight of the machine, and improves the vibrating efficiency; .
5) Uses one single motor to drive the vibrator via transmission shaft, avoiding the inconsistency of double motors;
6) High-precision guide bearings are used to assure the precise movement between the tamper head and the mould;
7) Heavy-duty machine frame, which uses high-intensity steel and advanced heat treatment, is wear resistant
