picture below show a simple runner system in mold construction, begin from nozzle until gate, nozzle for mold usually located in plate 1, plate 1 is upper plate,
when you design a runner system, basically like picture below, you must know location of product, is important when we decide where gate to be placed, here is the basic rule :
1. Look at drawing and 3D CAD data from the product, make sure you was choose where is cavity side and where is core side, give attention for tolerance of product
2. Do not locate gate in the precision tolerance, if is must to make a little grove in the product when you choose pin point gate type, Picture below use pin point gate type.
3. make sure the flow will steady for all side
