Profiles, Tubes and Filaments
Peter Profiles and Tubes
Ensinger demonstrates a high degree of excellence in engineering profiles and special tubes made of technical plastics for industrial applications. 
Geometries and materials precisely tailored to the specific application result in economical and high-precision solutions
To meet our customers’ requirements, profile and pipe extrusion, as well as coextrusion of different thermoplastics, can be performed using a wide range of  inline or offline processes such as printing and knurling, winding or cutting to size, thermoforming and welding, annealing and conditioning. 

Over 40 years of experience in the extrusion of thermoplastics into industrial profiles and tubes

For a broad range of industrial applications, we offer:

  • Economical and high-precision solutions
  • Extrusions technologies for profiles and tubes with various cross-sections and surfaces
  • Processes for further processing through to comprehensive solutions from a single source
  • Tools and operating equipment are designed and produced in-house
  • Prototypes produced with pre-series tools
  • Tolerances according to DIN EN 16941, DIN ISO 2768 or specific requirements

Why Ensinger

Experience and knowledge

Engineering advice based on many years of experience in the processing of thermoplastics combined with knowledge about the markets and the needs of our customers enable us to find the optimum solution to suit your requirements.

We offer our customers sound and individual advice about raw materials, applications and process technology. To find the individual solution we also can rely on close-knit knowledge transfer within the whole Ensinger Group.

Our non-binding, economical quotations are based on a qualified requirement profile.

  • Ultrasonic 
  • Reshaping by heat

Special extrusion processes

  • Co-Extrusion:
    Combining of different thermoplastics
    Reinforced and unreinforced material
    Different colours
    Combination of hard and soft materials
  • Jacket extrusion of metallic:
    Traction mandrel for bending operation 
    Voltage equalizing

Post treatments

  • Annealing process for reduction of internal stress,
  • Conditioning - Adjustment of required humidity and  physical properties

Hundreds of possible modifications

Improved and new materials are important milestones when it comes to technological developments. In our portfolio you will find engi­neer­ing and high-temperature plastics with suitable characteristics/ pro­perties for all kinds of different applications. Optimized sliding properties, low abrasion, high operating temperatures, strength, dimensional stability and chemical resistance are the best pre­req­ui­sites for replacing conventional materials, both successfully and economically.
Furthermore, almost 500 polymer modifications can be achieved. The application conditions involved determine the material selection. 

The basic thermoplastic polymers can be reinforced with carbon or aramid fibre, or dry lubricated. Using the co-extrusion method, reinforcing agents such as metals can be integrated, plastics with varying characteristics can bei connected by means of sheathing, or hard-soft connections produced, for example for sealing lips.

Ensinger produces profiles using the extrusion and co-extrusion method. For example full profiles, hollow chamber profiles and particularly thin-walled profiles with wall thicknesses of 0.4 to 0.5 mm made of materials specially adapted to the application in question.

Filaments from high-performance plastics for professional 3D printing

To enable the cost-effective and efficient production of very small batches, special applications or prototypes, Ensinger has expanded its product portfolio to include filaments made from high-performance plastics. Alongside the filaments in stock, we offer the creation of components made, for example from PEEK, PEI, PVDF or PPSU.


Due to many years of experience and enormous production know-how, Ensinger is capable of producing tubes with minimal diameters of 2 and 3 mm up tomaximum diameter of 90 mm. Any graduation of wall thickness is possible from 0.3 up to 20 mm.

Here, too, extremely narrow tolerances can be implemented in agreement with the customer. Benefits such as low tooling costs, low batch sizes and varying lengths offer even greater flexibility and lower-cost solutions.
