Evaluate the quality of the waiting chair
 
Today, there are still a small number of merchants that sell inferior chairs for the sake of profit. Then, how to identify the advantages and disadvantages of the row chair in the process of purchasing a waiting chair? However, the first thing I saw was the crack of the steel plate.
 
Causes of steel plate extrusion cracks in link chairs: Extrusion cracks are a common waste in extrusion, especially in hard alloys, and cracks should never be allowed to leave the factory.
 
1. The temperature speed is not properly controlled, the temperature is high, and the speed is too fast;
2. The speed control system fails;
3. The extrusion speed was not adjusted in time when the alloy was changed;
4. The squeeze began to suffocate the car, did not adjust the speed in time after extrusion;
5. Squeeze to the later stage, resulting in temperature rise and insufficient speed reduction.
