Interplastica 2022 Engel showcases intelligent injection moulding technology at Russian plastics trade fair

Source: Press release

Russia/Austria — From 25 to 28 January, machine engineering company Engel will welcome its customers and partners to its stand at Interplastica in Moscow again. The injection moulding machine manufacturer and system solution provider headquartered in Austria is making the potential of innovative digital solutions tangible by producing technical parts live on a tie-bar-less victory injection moulding machine.

At Interplastica 2022, injection moulding machine manufacturer Engel will show how parts with strict requirements can be produced on a tie-bar-less Engel victory 80 injection moulding machine. Three smart assistance systems from the company's inject 4.0 program ensure high production efficiency accompanied by consistently high product quality: iQ weight control, iQ clamp control and iQ melt control.

In each individual cycle, iQ weight control analyses the pressure and speed profile during the injection phase and compares the measured values with a reference profile. The injection profile, the switchover point and the holding pressure are automatically adjusted to the current conditions. This means that fluctuations in the raw material and ambient conditions are automatically detected and rejects are proactively prevented.

Without iQ weight control on the left, and with iQ weight control on the right: the software automatically detects changes in the raw material and automatically compensates for them within the same cycle.

iQ clamp control determines the optimum clamping force for the injection moulding process in question on the basis of mould breathing. In many cases, overmoulding and flash can therefore be reliably ruled out. On top of this, mould venting is improved and the mechanical load on the mould is reduced.

The third smart assistance system in this team is iQ melt control, which optimises the plasticising process. The software determines the optimum plasticising time for the application in question. Instead of plasticising at the maximum possible speed, the system fully leverages the part’s in-mould cooling time for the plasticising movement. This leads to improved melt homogeneity and is gentle on both the screw and the material, which in turn improves product quality.

In terms of design, too, the victory injection moulding machine presented at Interplastica 2022 pulls out all the stops for process consistency. The tie-bar-less clamping unit maintains the outstanding parallelism of the mould mounting platens during clamping force build-up and injection. At the same time, the force dividers distribute the clamping force evenly over the mould mounting platens.

Because there are no tie bars in the way, the mould mounting platens can be fully used up to their very edges. This means that very large moulds, such as multi-cavity moulds or moulds with core-pulls, fit on relatively small injection moulding machines. This keeps both capital expenditure and operating costs low while enabling compact production cells. Further benefits of tie-bar-less technology include fast mould setup processes and efficient automation solutions.
