Customer's Expectations

> Correct dimension of the part.
> Compact mould solution. 
> High structural result. Need to move weld lines where will not create internal stress or weak points.
> Complete filling of all the ribs and walls.
> Limit the injection pressure considering the customer machine indications.
> High production volume.

 

Our Solution

To provide a properly filled part, the maximum number of injection points was considered
The solution selected (Aa series and valve gate type) was ideal for those parts with requirement of high structural resistance because it is injecting the expected quantity of material. 
For the correct filling of the internal walls a CAE analysis was performed. This indicated also deformation areas and eventual weak points in the structure. Using the analysis result was  possible to suggest the proper cooling line on the mould.
In order to limit the flow length, a multi-level manifold was considered. This choice allowed a better system balance.
The solution applied can be used for many different pallet dimensions.

HRSflow system
The hot runner system is composed by 22 drops conical valve gate Aa series not prewired and hydraulic actuation. 2 levels manifold. Stack mould with offset nozzles.
The gate diameter was 6 mm and it is used with conical tip and external end ring.
