 Education, training

Nowadays the optimal utilisation and the handling of production tools and high-performance injection moulding machinery affect how economical are the production plants.
Despite the use of the best technique, if the adjusted parameters are not optimised the productivity will drop, and there will be more reject.
On the trainings and courses we are focusing on the presentation of typical problems for example:
  • During the adjustment of the screw if we do not take into account the screw diameter, the shear force will cause material damage and the production of gas melt.
  • The use of one back pressure even in the case of a bigger shot, ignoring the stroke capacity, the cycle time and the melt temperature inhomogeneity caused by the screw shortening.
  • The use of one injection velocity during the mould filling, which is the principle cause of the free jetting and the gate rigidity.
  • Avoid the errors caused by switching to holding pressure, and the stress which comes from over injection moulding.
  • The adjustment  of a similar holding pressure run in amorphous (ABS) and semi-crystalline (PA) plastics.
  • Among all the factors taking into account only the tool temperature in the preservation of the form and size performed with heat sink.
The main goal of the courses is the invitation to a conscious and deliberate work. Its steps are the following:

1.    Error analysis

e.g.: Sink mark on the ribs.

2.    Think through the possible techniques for correction.

Is it caused by gate freezing or bad holding pressure parameters?

3.    Interference to make the correction

Parameter changing (rates, pressures)

4.     Double check, documentation

The modified parameter’s effect on the other parameters, transferring the modifications through the technology.

We recommend the participation in the courses for the following people:

Project and QS engineers, shift managers, group leaders, machine adjusters, moulding technologists, tool makers, maintenance staff.
