  7. Pipe extrusion

Extruded pipes are a common product that comes in many shapes and sizes.  Several kilometres of pipe are used annually in the construction, installation engineering, sewerage and, for example, floor heating sectors.

In the production process of normal plastic pipes, the molten material is forced through a circular mould and then calibrated and cooled in a controlled manner. After cooling, the tube is cut to length or wound on a reel. 

For the specialisation of tube extrusion, Plastima cooperates with specialised machine manufacturers on the basis of exclusive contracts. Not only do we supply the extruders, we can also advise you on follow-up equipment. This includes measuring systems, vacuum and cooling tanks, corrugators, drawing units and seeding units. Plastima is also the right place for automated post-processing.

To optimise efficiency, Plastima offers intelligent solutions for meter weight control and material handling. 


Types of pipe extrusion at Plastima

For its pipe extrusion specialisation, Plastima works exclusively with the renowned machine manufacturer WEBER. The family-run company Hans Weber Maschinenfabrik, based in Kronach, Germany, has focused on 100% German quality for 100 years. With a team of over 400 specialists, WEBER supplies customer-specific extrusion solutions with the latest technology in control, drive and screw geometries worldwide.

WEBER machines are available in the following designs:

  • Parallel twin-screw extruders
  • Conical twin-screw extruders
  • Single-screw extruders
  • Single-screw co-extruders
  • Conical twin-screw co-extruders

For pipe extrusion, WEBER develops extruders up to 2000 kg/h and pipe heads for single or multi-layer pipes with a range from 5mm diameter to 800mm diameter. For PVC as well as for PO, PE and technical plastics, such as PEXa, WEBER is the right place for you

For proper control of the extrusion process, it is important to pay attention to the upstream of the extrusion line. Within the pipe extrusion specialisation, multiple components are widely used, such as the addition of an antistatic additive, a dye or, for example, the composition between PVC powder and PVC grinding material. To monitor and control the throughput of valuable material, material conveying and dosing plays an important role.

Conveyor systems

Using conveyor systems can drastically reduce the reliance on manual handling. Well-kept material transport requires a relatively low investment and contributes to operator efficiency, reduced production downtime and cleanliness of the production floor.

Dosing and measuring equipment

For a stable and efficient extrusion process, Plastima has supplied high-end gravimetric mono and multicomponent dosing systems and measuring equipment for tube extrusion since 1985 with iNOEX.

Since iNOEX was founded in 1984, the company's focus has been on improving the process parameters of the extrusion process. With an eye on efficient use of valuable raw materials, iNOEX makes it possible to calculate highly accurate gauge weights by using the loss-in-weight principle. 

However, iNOEX goes beyond just measuring material take-up. The company's specialisation has translated into the development of ingenious thickness and ovality measurements. With these, we can offer both a manual solution for spot checks, but also constant measurements using advanced methods such as X-Ray and Radar technology. 

The engineers at iNOEX and Plastima like to think along with you to make your process as efficient as possible.

Ever since the 1960s, Plastima has been focusing on offering complete extrusion lines. An important part of this is advising on the right downstream. 

Besides extruding the tube, the downstream equipment also has an important influence on the contours and quality of the product. Plastima works exclusively with SICA and ITIB for downstream. 

Besides conventional downstream equipment such as drawing units and cutting units, Plastima can also give you recommendations on the installation of, for example, corrugators, reels and machines for automated fitting of fittings and seals.



Pipe treatment

What started as a company in the production of aluminium profiles, is today one of the most well-known suppliers in the field of durable downstream equipment for producing both smooth and ribbed tubes. Based in the Bologna region, the company employs 130 people and focuses mostly on R&D to continue pushing boundaries and supporting industry automation. 

SICA offers the following machines within its specialisation:
  • Pullers with a wide diameter range for the most consistent pulling force and speed.
  • Guaranteed for a stable production process.
  • Highly accurate sawing and cutting units for various wall thicknesses and applications.
  • Extreme precision ensures high tolerances.
  • Automatic and semi-automatic machines for forming connections and fittings including the possibility of inserting seals.
  • Reels with integrated packaging function for wrapping the wrapped product.
    Packaging machines of solid tubes, both by means of belts or bags.

Pipe structures

By using corrugators, tubes can be calibrated in a ribbed structure. A ribbed plastic pipe offers very high stability in a highly flexible structure. Ribbed tubes are widely used in the automotive industry and installation engineering. The most well-known application of this type of pipe is the hoover stroke.

Thanks to years of intensive development, ITIB is today among the most innovative and reliable manufacturer of equipment for the purpose of ribbed tube production. ITIB's proven technology is applicable for thermoplastics and can be used for both single- and double-walled tubes.
