Analysis and optimization of forming processes
We analyze, simulate, and optimize your forming process
We specialize in the manufacture of innovative 3-D applications made of plastic and the improvement of existing ones. We develop new methods, processes, and technologies for packaging, technical components, and electronic products.
Our focus is on thermoforming, also known as deep-drawing, and similar shaping processes. We design new control systems for forming processes, develop methods for specifying the forming behavior of materials, help you optimize your molded parts, and identify sources of error.
We transfer topical themes such as digitalization, Industry 4.0, and machine learning to thermoforming and hence make a significant contribution to the use of processes by material suppliers, machine and mold manufacturers, and processing companies in this sector.
Our motivated team looks forward to working with you to overcome challenges and push boundaries.
We analyze your forming processes using our experience, material/machine/process data available to us, and the active use of our technologies. Geometry measurement is achieved using projection and scanning processes. We use infrared measurements to determine the temperature of the plastic inline during the forming.
If needed we test your manufacturing process experimentally on our thermoforming test rig or using a numerical simulation model, so allowing the targeted rectification of faults. Based in the acquired data, we advise you about parameter and mold optimization for manufacturing your molded parts.
We assist you, for example, with:
Regardless of whether you are dealing with existing or new moulded parts - we help you from concept to production.
Based on your requirements or sample applications, we create a production concept and evaluate conventional and innovative heating and moulding technologies. We show you the individual advantages and disadvantages.
In addition, we further develop existing technologies or design completely new ones.
We use various material and process databases, draw on our experience, rely on an experimental, numerical simulation for functional analysis and parameterization and use statistical methods for technology analysis.
Here we can help you:
The material that is used largely determines whether your requirements on the molded part are met. We can assist you with comparing and selecting suitable semi-finished products. Besides using our material database we also use a variety of methods for characterizing plastic materials.
Depending on the application and required properties we select a suitable method for testing the material behavior.
The concept of measuring the forming properties of materials, as well as associated methods, is something we are constantly working on. You also benefit from this knowledge.
We can, for example, assist you with:
We check the requirements of your products and use experimental tests and numerical simulation to identify improvements. This can, for example, concern the load limit, geometry, or permeability.
You receive concrete proposals from us as to how to modify your products and what technologies to use.
We assist you with:
A selection of commonly asked questions about forming processes.
There is currently no generally accepted definition of thermoformability. It is often understood to be the mechanical deformability of the material during forming. There are already methods for measuring this, for example the uniaxial and biaxial tensile test, TMC (thermoforming material characterization), bubble inflation, and thermoforming using test structures.
Forming air impact technology involves using a nozzle system to direct compressed air in the upper tool onto the semi-finished product. This causes both a mechanical and thermal impact on the semi-finished product. By selecting suitable nozzle parameters, the forming process and also the wall thickness are influenced.
Conformable electronics are dynamically deformable, structural 3-D electronics. Cost-effective, planar, and conventional processes are, amongst other things, used for the assembly and printing of these components because the shaping is only performed in the last step. We have in-depth experience of thermoforming, process and technology development, and experimental and numerical simulation. This know-how is the basis for forming hybrid semi-finished products into the desired shape.
The correct use of numerical simulation leads to a greater understanding of the thermoforming process and to more effective development work. Whether this benefits your situation or not depends on your particular application and must be determined. We do this taking account of the materials, process, and specific objective.
With complex technologies or molded parts, such as conformable electronics, it is essential to use numerical simulation for effective process dimensioning and parameterization.
By systematically acquiring and evaluating material, machine, and process data, it is possible to link information via "artificial intelligence", to identify features, and take actions. There is also anonymous exchange and processing of data between the participants of the value-creation chain. Machine learning and "deep learning" significantly improve the process monitoring and quality testing during the production.
