You are also welcome to send us drawings (sketch, PDF or 2D-DXF) or 3D data, step zipped. Step please in AP214.
Please compress your files to minimize the file size.
Please send us your 3D data in Step AP 214 as a closed volume model solid model and in tool position.
If the plastic part is outside of the tool coordinate origin and rotated in several axes, please position it in tool position.
Please mark the position at which the injection moulding is to take place, either with spheres in the CAD data set (assembly), or another marking, e.g. as a screen image (screenshot) with arrows.
Please use the possibility to contact us via video conference.
In order for an EXAflow to “work”, we need a flexible plastic. The bent tunnel is “forcibly demoulded”. While it is doing this, it must not break.
We recommend that you look at the elongation at break in the technical data sheet of the plastic under the mechanical properties, as well as the stress-strain diagram. The elongation at break must be at least 40% – better 50%.
We have already experienced that plastics with an elongation at break well below 10% were still flexible.
If you are not sure if your plastic is flexible enough, please contact the technical support of the plastic manufacturer.
An even better value would be the flexural modulus of the plastic. Unfortunately, the plastic manufacturers treat this value stepmotherly. You will hardly find any information – and if you do, then not in percent but
mostly only in MPa, Megapascal. The modulus of elasticity also provides information about the flexibility of a plastic.
