Please visit us during K-show from 16th until 23rd of October 2019 on our booth A51-03 in hall 12 (SGE Swiss Pavilion). Together with our partners Glaroform AG and Beck Automation AG, we are presenting an exciting application in order to show that plastic can be an energy-efficient, sustainable and future-oriented material.
We have put together an interesting article describing the ICM-application on a KraussMaffei machine with an injection mould from Glaroform, IML from Beck, optical inspection from Intravis and evaluation in the MES PiSolutions from bfa.
Efficiency for the environment – K-Show 2019 Press Release
The Exhibit: Redefining the Possible
There is no doubt that the K 2019 trade fair will take place in the shadow of the discussion about environmental protection and the correct use of plastic. The industry has a duty to present solutions and to prove that plastic can be a future-oriented, energy-efficient and sustainable raw material. Booth partners Beck Automation, GLAROFORM and bfa solutions have taken this opportunity to present a production cell that, in many respects, redefines the limits of feasibility of injection moulding and decisively supports the quest for a “closed-loop” recycling economy.
A 200 ml plastic container produced with a 4-cavity ICM (injection-compression moulding) configuration from GLAROFORM and Krauss Maffei High Performance (formerly Netstal) impresses with ground-breaking material efficiency. The unrivalled low wall thickness stretches physical limits, not only resulting in considerable material savings, but also leading to a further reduction of the already highly competitive production cycle time. The lower closing force and injection pressure required thanks to the new process reduces the forces acting on the machine. This extends the life of production plant, thus increasing sustainability while minimising energy consumption. With this machine, GLAROFORM clearly demonstrates its ability to innovate and is an expression of the company’s philosophy of delivering the highest precision together with a uniquely robust design.
Beck Automation presents compact, high-performance IML automation for wrap-around labels. The system is characterised by the dynamic process, process stability and very high availability with short cycle times. The precise interaction of the individual components of the plant including automation systems, the injection moulding machine, the mould, label quality and the optical control system increases productivity while adding value. The use of lightweight materials on the main arm and the deployment of high-performance linear motors enable fast, dynamic movements. The main axle has two drive motors, which improves dynamics and extends the life of both the belts and the motors. Inclined label magazines, where the labels are contained with the print image facing down, minimise label warpage. This guarantees an optimised, precise positioning of the labels. Even with very fast cycle times, the labels are separated and transferred to the cores without disruption. The removal, transfer as well as the depositing and stacking of the products all impress with captivating levels of automation. The modified logbook which has recently been integrated into the HMI control system features user administration, parameter monitoring, simplified error analysis as well as a maintenance interval. In addition, the IML system is equipped with a 10-camera vision system from Intravis. This monitors the outside of the containers through 360° while at the same time inspecting the inside of the product.
Furthermore, labels with a digital watermark from label supplier Verstraete are deployed. This new technology enables efficient sorting at recycling plants equipped to handle this technology. In addition, the digital watermarks which are invisible to the naked eye can also be used as codes, in the same way simple bar or QR codes are used today.
MES PiSolutions by the company bfa solutions ltd provides the interface between the production and the ERP levels in this sophisticated and pioneering application. It has the task of collating and evaluating data from the injection moulding machine, the handling process and the quality assurance system and to make this data available to different users. The various functions of the MES help to make, among other things, downtime, defective products and production progress all visible in real time. This way, problems can be dealt with quickly or a tool change with a preheated tool can be prepared just-in-time. Thus the utilisation and efficiency of production plant and production lines can be significantly increased. This makes it possible to save even more energy, time and money, and further demonstrates the idea of plastic as an efficient and sustainable raw material.
In the face of changing consumer demands, the plastics industry today has the opportunity to create a win-win situation for the environment as well as its own stakeholders. The production plant shown here, with the significant reduction in wear and consumption in terms of materials, energy, work and the plant itself, while at the same time increasing output, stands for an even more efficient future. We will be presenting the state-of-the-art of tomorrow’s technology at the K 2019 in Hall 12, Booth A51-03 (Swiss Pavilion).

The Technology: Modern Processes
Injection Compression Moulding (ICM)
Injection Compression Moulding (ICM) is a manufacturing process that combines injection and compression moulding. This is a dynamic injection process: compared to conventional injection moulding, the mould is not closed completely at the filling stage. As a result, the closing force is then used to distribute the injected material throughout the mould cavity.
Today, ICM is particularly common in the production of technical parts such as DVDs or lenses. Here, the ICM process offers essential advantages in terms of dimensional accuracy and moulded surfaces. Conversely, the market for ICM systems in the field of thin-walled packaging is still in a state of development. The first early adopters are emerging, both on the supplier and the user side. These companies are mastering the challenges of this process and thus creating economic as well as ecological benefits for the environment, society and for themselves. The key benefits of Injection Compression Moulding of thin wall packaging are as follows:
- Material savings of up to 25%
Greatly improved filling behaviour with a high flow path/wall thickness ratio enables significant reductions in wall thickness.
- Enhanced possibilities regarding raw materials
The compression moulding process enables plastics to be processed, for example, which are usually unsuitable for thin-wall injection moulding due to their low melt flow rate (“strength”).
- Increased output by up to 5%
Due to the thinner wall thickness, faster cooling and thus a decrease in production cycle times decrease.
In Mould Labelling (IML)
Since IML is a very dynamic process, operational efficiency is the sum of all the machine’s high quality components.
First, the labels are sucked out of the label station. In the second step, the labels are placed on the cores and held in place by a vacuum. The cores move into the cavities to transfer the labels. In this phase, the labels are blown off against the vacuum, electrostatically charged and thus positioned in the mould, mapping the cavities as closely as possible and held in place.
The level of process design and the quality of the labels are decisive for process reliability, reproducibility, part quality and cost-effectiveness. A high-quality automation system, which is equally convincing in terms of availability, process reliability, stability and longevity, is crucial for return on investment and the level of added value.
- Closing force requirements reduced by up to 40%
Due to the use of the closing force to distribute the material in-mould, injection pressure can be significantly reduced. This in turn lowers the closing force, which serves as a counterforce to the injection pressure.
- Reduction in energy consumption by up to 20%
Due to the lower closing force and injection pressure required.
- Lower maintenance costs
Due to the lower forces at play, the whole load on the production plant is reduced, which leads, as expected, to lower maintenance costs.
- Reduction in production area by up to 15%
Because smaller injection moulding machines with less closing force tend to be used for ICM, the production area required can be reduced.
