MFWL 40​


THE Machines Yvonand SA designs, develops and engineers ‘in-house’ all composite tube extrusion, metal forming and laser welding lines. Components are engineered and manufactured to the highest standards, technologies and precision, resulting in unsurpassed productivity, line performance and end-product quality.

Closed-loop production management and quality systems assure that highest productivity and cost-performance efficiencies as well as world class operational excellence is attained.

A range of complete production lines and processes is available for multi-layer composite tubes plastic/metal products (MFWL), with pipe extrusion and metal-up stream processes, forming and laser welding and composite pipe down-stream process all from one hand.

Mono-layer metal forming and laser welding stands (FWM) can be incorporated in to existing production lines as well as be complemented with all metal tape up-stream handling and welded tube down-stream processes. All technologies from one single and experienced supplier.

Plastic pipe extrusion:
Inner and/or outer plastic, with THE own or customer bespoke extruders. Integrated polymer mixing, dosing and feeding available as well as layer thickness control.

Metal Rollforming:
In-house manufactured precision roll-forming tools engineered with finite element simulations to impart minimal stress and strain, avoid surface damage and provide process stability. High quality and use of materials assure longevity of the tools. Quick-change carrier systems benefit in low set-up times and operational excellence.

High quality laser welding with proprietary orbital seam tracking system. Laser power source and beam quality adapted and configured to best suite the application.

Quality Control:
In-line monitor and measurement of all geometric parameters with fully integrated in-line continues non-destructive weld seam and tube quality control systems with exclusive ICO and ECC (Internal Crack Observer) eddy current measure.

Line Controls:
Centralized line control systems, with recipe management to assure process stability and operational excellent. Line controls have data logging capabilities for track and trace requirements of key required process parameters and quality checks as well as prepared for customer industry 4.0 requirements. User friendly HMI and line management systems.
