Anybody can tell me what is the advantage & shortage of pin point gate (03 -plate mold)?

A three plate mold is generally used when gate poisition at the side or edge of the molded part is objectionable or would likely cause no filll or exteremly hard to fill sections of the part. When used as a central fill point in a symmetrical part, it allows for uniform part filling without part weakening weld lines.


I hope it helps

ITS VERY SIMPLE


ADVANTAGE:-


IT LEAVE LESS MARK ONTHE COMPONENT


LESS MATERIAL WASTAGE


IT SOLIDIFY SOON SO THAT INTERNAL MATERIAL DOES NOT COME BACK DURING PAKING


DISADVANTAGE:-


MORE INJECTION PRESSURE IS REQUIRED
 
THANK YOU VERY MUCH KEVOKAM & SADHU.



BUT I HAVE ANOTHER QUESTION: IF THE APPEARANCES (GATE MARK, WELD LINE,



FILLING...) ARE NOT IMPORTANT, WHICH TYPE OF MOLD WILL BE CHOSEN? PIN POINT



GATE OR SIDE GATE? THE PHYSICAL PROPERTIES OF THE PART ARE DEPENDENT ON



TYPE OF MOLD OR NOT?
 
yes ur right the gate depends on type of mould as well as more on component accuracy and if u want no matk on component u can go for hot runner mould it will save wastage as well as ur cycle time ok best of luck keep going
