Modules and Assembly

m-tube – modular assembly line

Optimal workflow – that’s what it’s all about. Construction plastics can be assembled in different ways. They can be welded, glued or assembled into assemblies. Labelling is also useful for some applications. The assembly process is often a manual activity that must be coordinated as effectively as possible. The flow of goods must not come to a standstill when striving for the shortest possible setup times and thus low setup costs. In addition, with the high variability of plastics, assembly must also be flexible.


Thermoplastics can be welded together. This process is called plastic welding. There are various methods for this, which we bundle into the modular m-tube assembly line: Welding can be done either without or without contact. The foundations for this must already be laid in the planning and construction of the product. We offer the following procedures with m-tube:

  • Ultrasonic welding
  • Heating element butt welding
  • Hot gas welding
  • Extrusion welding


The bonding of plastic materials is a powerful process and can be used to connect two thermoplastics as well as to connect to other materials. Bonding is a chemical connection process and therefore has several advantages. This includes even stress distribution so that materials are not damaged. There is also no part distortion.

In order for the adhesive bond to work well, the right material and adhesive must be selected, the adhesive layer must be applied optimally and the workpieces must be designed correctly in accordance with later stress at the adhesive points.

In the assembly line, the materials are prepared. They are cleaned and degreased and surfaces are sanded or chemically treated.

Assembling modules

One of the great advantages of thermoplastics is that they can be combined with similar or different materials to form modules. The best materials are used depending on the application requirements. There is real innovation potential in this combination. For example, heavy batteries for operating wind turbines are now skilfully held together with support structures made of plastic. This makes transport much easier at heights of 50 to 60 meters.

A well thought-out assembly is also essential for the constructing modules. In this processing stage, not only the costs but also the load and wear values are decided.
