Corelco - Extrusion Lines - Lignes d'extrusion

Choice of production's process

Blowing process

Invented in early 60's, the blowing process is still nowadays efficient for standard production of medium size of corrugated pipe.
On the other hand it's limited for small size and doesn't offer many production's evolution possibilities.
Vacuum process

It's a huge evolution permitting a new vision of actual production and considers the production of tomorrow, without any kind of limitation such as diameter, profile, thickness control and use of material.


Corelco was already convinced in it in 1992, start-up of development program which permitted us to set up an in line pre-wired extrusion line and also to set up the sequential running mode which became essential for automotive fuel line production.

Our technical choice to assure PRODUCTIVITY, RELIABILITY and LONGEVITY
simple and clever design, a judicious choice of material associated to practical heat treatment, a control process which keeps developing, are the base of our know how.

• nitrited cast iron channels and quenched steel curves.
• side adjustment on central for a quick mould block releasing.
• water cooling in a turbulent network for a better thermic exchange.
• AC drive for an adjusted range of speed.
• torque limiter to protect mould blocks.
• quenched steel mould blocks for a longer life (guarantee for 30000 hours) and a better thermic exchange.
• automatic lubricating system and oil collecting device for an environmental respect.
• process control with last version of PLC...
