What you have learned in the electrical enterprise is very comprehensive, from the wiring, installation and debugging of the control cabinet to the parameter selection, structural principle and hardware wiring of some control elements.

Jiangnan molding technology: Zhouzhuang, located not far from the east side of Zhangjiagang Bridge, reached its glorious period 20 years ago. Now, like most enterprises, it is said that due to the deterioration of leadership relations, orders from big customers such as GM and Mercedes-Benz in Shanghai and Wuhan have been lost. Jiangyin's enterprises are not small in scale, but they lack vitality and the company structure is redundant. It's hard for you to make any big progress (big companies have this common problem). The most important thing is that the main production equipment of molding enterprises is injection molding machine, and the estimation you have to make is also a piece of equipment, which is not closely related to the specialty (process adjustment is mixed). The failure rate of machines like that is not high, and it is impossible to grow in three to five years.
