Plastic parts injection moldin
The injection molding process of plastic parts mainly includes filling. Pressure holding, cooling, stripping and other 4 stages
Bottle blowing
The blow molding process is a bidirectional tensile process, in this process, the PET chain is bidirectional extension, orientation and arrangement, increasing the mechanical properties of the bottle wall, improving the tensile, tensile and impact strength
Circuit board inspection
Check the installed lines according to the circuit diagram, and check the installed lines one by one according to the circuit connections in a certain order
Switch welding
The welding of the switch is divided into two kinds: hand welding and automatic welding. According to the actual installation method, automatic welding can also be divided into dip welding and stop welding
Hit screws
The screw production process is divided into 7 steps, respectively, annealing, pickling, drawing, molding, grinding, heat treatment grade surface treatment.
