Coextrusion extrusion head

pipefor the plastics industryspider

Tooling for mono- and multilayer extrusion
Suitable PVC toolings for a great variety of applications

• Besides the extruder, pipe heads are one of the most important components in a pipe extrusion line.
• The Spider series provides a wide range of pipe heads covering the complete range of possible pipe diameters.
• Tooling is available for foam core pipe as well as compact multi-layer pipes, including solutions with a middle layer made from recycled materials or with high filler content.

Your Advantages

• Wide throughput and pipe dimension range thanks to flow channel geometries optimally adapted to pipe head sizes
• Best pipe quality, good pipe surfaces and low pipe overweight
• Processing of all standard PVC compounds and stabilizer systems
• User-friendly, robust design with easy handling in production and set-up cycles
• High operational reliability and easy maintenance due to high-quality materials and improved design

Our Offer (general)

• Outer diameters from 6 to 1,600 mm
• Different pipe heads with classic single spider concept for diameters up to 710 mm
• Twin-strand tooling for diameters up to 250 mm
• Four-strand tooling for diameters up to 50 mm
• Flow channel surfaces chrome-plated as standard (options: stainless steel or multiple chrome-plating)
• Support or carriage systems adapted to pipe head size and weight
• Optimized heating capacity
• Option: thermal centering and heating tape insulation

Spider NG series
The new Spider NG series offers a totally redesigned flow channel and an innovative die-clamping system.

Your advantages:

• Maximized dimension ranges at every size and all pressure classes
• Highest throughput rates for each size
• Best processability of all common PVC formulations and stabilizer systems
• Best processability of highly filled formulations and recycled materials
• Keeping the smallest wall thickness differences over the entire pipe circumference
• Excellent mechanical and optical pipe properties

Our offer (Spider NG)

• Innovative die change system with fixed centering
• Diameter change in less than 15 minutes (example: Spider NG 250)
• Wall thickness change in less than 8 minutes (example: Spider NG 250)

Double spider pipe heads
Double spider pipe heads use staggered spider positioning offering advantages for thick-walled PVC pipe production and very high throughput ranges.

Your advantages:

• Best mechanical pipe properties
• Excellent wall thickness distribution enabling reduction of pipe overweight and material savings of approx. 1.5%
• Perfect inner pipe surface
• Very high throughputs possible

Our offer (Double spider)

• Seven sizes of double spider pipe heads for diameters up to 1,600 mm
• All flow channel surfaces are chrome-plated

3-layer pipe heads for foam core pipe extrusion
Pipe heads for 3-layer PVC pipes with foamed or compact middle layer; example: Spider 200-3 pipe head for 3-layer pipe with diameters up to 200 mm.

Your advantages:

• Short flow channels and small volume enable processing of various formulations and stabilizers
• Optimized distribution channels provide perfect layer distribution and low pipe weight
• “Spider” design concept suitable for foamed to compact, high-filled and/or reclaimed materials
• Modular concept that can be converted to a 2-layer system

Our offer (3-layer)

• Cover dimensions from 32 mm up to 710 mm
• Throughput rates from 350 kg/h up to 1,600 kg/h
