NEXA-Expansion Line

Developed as a modular system for the continuous expansion of heavy wall tubing in the range of 12 - 200 mm (expanded diameter) with wall-thickness ranging from 2.0 - 6.0 mm. Depending on the size, quality and consistency of the crosslinked tubing, speeds of 3 - 4 m/minute or even higher can be achieved.

The expansion line consists of the following major modules:

  • Portal unwinder
  • Belt Haul-input module
  • Double pressure oil-heatingmodules
  • Expansion and calibration module
  • Belt Haul-output module with pinch rollers
  • Clamping module
  • Cutting module

Features:

  • New modular design, state of the art electronics and drives
  • Reliability & longitudinal change control
  • Heating by means of heating elements
  • Precise temperature control
  • Continuous circulation of the heating liquid


  • 1 illuminated view window per element for observing the product during the production process and for maintenance
  • Pressure control for pressure inside the tubular heater
  • All drive elements are made of none-corrosive materials
  • Liquid level indicator & Internal/external pressure control

HW and IR-expansion line

HW-expansion line

Expanded sizes up to 20mm.
Shrink ratio 2:1 and 3:1.
Speeds up to 25 m/minute, depending on size, quality and consistency of the tubing.

Features

  • Easy operation 
  • Non-liquid heating system 
  • Changing from 1 size to the other in less than 5 minutes
  • Reliability

IR-Expansion line

Expanded sizes from 5 mm up to 50 mm (expanded inside diameter). The IR machine will expand 2:1 and 3:1 thin and medium wall heatshrinkable tubing. Speeds of up to 12 m/minute, depending on size, compound composition and consistency of the crosslinked tubing.

Features

  • Easy operation
  • Non-liquid heating system
  • Changing from 1 size to the other in less than 5 minutes
  • Reliability
  • Ideal machine for single and dual wall (adhesive lined) polyolefin and elastomeric, Kynar (PVDF) and fluoro-elastomeric tubing

Flattening Machine

The PTL/Compo flattening line is for flattening heat-shrinkable tubing to be used as identification sleeves. This line is capable of flattening expanded heat-shrinkable tubing of multiple diameters ranging in diameter from 2.4mm up to 76.2mm.

Consistent flattening can be easily achieved. The flattener has been designed and equipped with controls for product consistency and reproducibility.

Halogen-free and halogenated, flame-retardant polyolefin heat-shrink tubing in 2:1 and 3:1 shrink ratio, as well as other heatshrinkable tubing (such as fluoropolymer based products) can be easily flattened to any desired ‘puff’.


REVEX - Revolving Expander

New design, different expanded shapes possible.

  • Output: 40-60 pcs/hr.
  • Expanded sizes from 40mm to 90mm diameter
  • Wall thicknesses up to 12 or more, depending on material
  • Multiple layers

Cutting lines

Our cutting lines have been designed for cutting thin-, medium- and thick wall tubing.


Compounds for heat-shrinkable tubing

The PTL range includes various commercial polyolefin compounds for thin wall applications, and special compounds for high grade applications including defense. Also compounds for medium- & thick-wall tubing for low voltage and medium voltage up to 36 kV are available.
