1.Valve gating nozzle ,is used the valve pin tip mechanically closes the gate on completion of the holding pressure time .valve gate creates on gate vestige.but leaves only a barely visible ring, for this reason , it is the best solusion for all parts where surface quality is critical
 

2.Due to the relatively large gate openings, according to the part requirement , is realized with this gating method . as a result ,valve gating offers higher mold filling quantity and mold filling speed to make the part in good characteristics,and imparts the lower mold filling stresses and also gives a wide processing window suitable for the most difficult the thermoplastics that contain sensitve additives
 

3.Good color changing , and the better parts quality requirement can be reached , throught opening the different gates in different time by serially control
