The speed projected from nozzle is fast, advantageously reduces the manufacturing time of individual plastic chair.It can be to hot melting plastic by fin
It is stirred so that the material distribution of hot melting plastic is more uniform, and the quality of Plastic chair is preferable.It can be further by through-hole
Increase mixing effect.Homogeneous portion can not only be such that the plastics of both sides are sufficiently mixed in homogeneous portion, and provide one and delay
Space is rushed, the violent head-on collision of both sides plastics is reduced, this advantageously reduces screw rod rotary resistance, can reduce and turn to variable speed electric motors, particularly
The requirement of square can also reduce power consumption, energy saving.
Therefore, have the advantages that manufacture efficiency is high using the utility model manufacture Plastic chair, the performance of enterprises can be improved,
And the utility model is simple to manufacture, easy to implement.
