What is fan gate?
Fat gate, namely ,the shape of the gate looks like a fan.Fan gate is usually used on
multi-cavity molds or two-plate molds.
It is a common
edge gate located located in the sidewalll of the part to prevent restriction of resin flow. Since the gate could distribute melt resin into the cavity more evenly, thus it is normally applicable to parts that require a high degree of flatness and absence of flow lines. It also minimizes the possibility of part warpage and helps to maintain dimensional stability.
From above pictures we could see that the fan gate has shortcomings as well. Since the gate is too wide and it may increase labor cost to degate after molding. Besides the gate is long leaving visible trimming mark, it may affect cosmetic look as well. And there is high potentiality for air entrapment if not carefully dimensioned.
In seeking a way around the shortcomings of fan gates,
HS Mold in China has developed special tapered run gate which has several distinct advantages. We enable you to quickly design and specify the dimensions of all forms of fan gates for your injection mold project.
