Consultation with in-depth knowledge and process expertise

W&H has been active in the extrusion retrofitting business for 10 years and has successfully completed more than 2,000 retrofit projects worldwide. This business profits from the company’s more than 50 years of market leadership with new machines. The installation and support is provided by the worldwide W&H Sales and Service network. Over 350 experienced service technicians from the 12 service centers work worldwide. This enables comprehensive support from the offer to the on-site commissioning – always with the goal of putting the system back into production as rapidly as possible and minimizing downtimes.

Replacement of the existing gravimetric dosing unit on a non-W&H line

Replacement of the existing gravimetric dosing unit on a non-W&H line

Resin feed separation caused film gauge and width variations on an existing blown film line. This was corrected using new gravimetric metering equipment. The modification shortens the change-over times and improves metering accuracy, especially when feeding small quantities.

Updating Automation with PROCONTROL TS (Touch Screen) on a non-W&H line

Improved Film calibration with VARIOCAGE on a non-W&H blown film line

Improved Film calibration with VARIOCAGE on a non-W&H blown film line

Using the VARIOCAGE with perfect film bubble support, unacceptable width tolerances, which caused conversion problems on downstream equipment, were completely eliminated. Furthermore, the customer noticed a significant improvement in the film quality because the CFK (carbon fiber) cage guide segments leave fewer marks on the film.

Exchanging the existing winder with the FILMATIC S multifunction winder on a non-W&H line

Unsatisfactory operation, poor winding quality and lack of operational safety of the existing, outdated winder prompted the customer to do something about it. With the integration of the FILMATICS winder with center and gap winding, the needs of the customer could be met with a winder featuring state of the art controls, winding quality and operational safety.
