I-Mold GmbH & Co. KG has developed a sprue adjuster, which the company said enables a toolmaker to change the direction of melt flow in the runner system of an injection mold.
By a simple turn of the sprue adjuster, the flow of melt to the individual mold cavities can be selectively freed or blocked. The setting is done manually from the mold-parting surface, when the mold is open. I-Mold said this is very easy to do and requires only a brief interruption of the molding cycle.
This makes it possible, for example, to isolate a bad cavity, or in family molds to isolate a cavity that is needed for some applications but not all.
The sprue adjuster is available in three sizes. The toolmaker machines the melt flow-ways into the sprue adjuster's cylindrical body.
I-Mold is based in Brensbach, Germany. In North America, the sprue adjuster is sold by DMS Inc. of Oldcastle, Ontario.
