RETROFITS for Non-W&H Lines
Upgrade your blown and cast film extrusion lines with W&H technology and performance
Get in touchUpgrade Your Blown Film Lines with Retrofits from W&H
If you have blown or cast film lines from other machinery manufacturers, you can still optimize your machine's performance with the latest tecnologies from W&H.
W&H offers free consultations to discuss goals you have for your existing lines and how retrofits from W&H could help you achieve them.
Retrofits for Non-W&H Blown Film Lines
10 - 60% Increased Output with the Xtreme Performance XP Air Ring
10 - 60% Increased Output with the Xtreme Performance XP Air Ring
The new XP cooling system from W&H was introduced in at the K 2019 in Düsseldorf.
Blown film lines from both W&H AND other manufacturers can be retrofitted with the XP cooling system.
Output can increase from 10 - 60%
W&H technology for a small investment

Installation
Installation of extruders, including all components, will be done by W&H service technicians.
Installation: 1 – 2 days per extruder (including training)
New MAXICONE Die Heads and Dies

New MAXICONE die heads and dies can be retrofitted to all W&H blown film lines as well as other systems.
Installation
Die installation, including all necessarycomponents, will be done by W&H service technicians.
Installation: approx. 5 days (including training)
ARCTIS and MULTICOOL Air Rings
Increase your output and film quality by retrofitting W&H dies or MULTICOOL or ARCTIS air rings, which are available for W&H and other dies. A new gauge profile controller is available as an additional option.

Installation
Installation of air ring retrofit packages, including all components, will be done by W&H service technicians.
Installation: approx. 5 days (including training)
VARIOCAGE
Improve film width tolerances with optimal calibration that saves trim and satisfies your customers with its operating properties – all with the non-contact NOSTIC cage.
Example of 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.

The VARIOCAGE film calibration unit ensures tight tolerences.
Installation
The film calibration unit and components are assembled by W&H service technicians.
Installation: approx. 2 days (incl. training)
PROCONTROL Automation

Updating Automation with PROCONTROL TS (Touch Screen) on a non-W&H line Combining machine functions of several operator terminals across the machine using a user friendly touch screen control unit, has simplified machine operation considerably. The operators are better informed, they avoid errors and are consistently producing better quality products.
New Gravimetric Weighing System and Vacuum Feeders
example of a success replacement 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.

New gravimetric system (module G) and vacuum feeders can be retrofitted to all W&H blown film lines as well as extrusion equipment of other manufacturers.
Installation
Installation of gravimetric system and vacuum feeders, including all components, will be done by W&H service technicians.
Installation: approx. 1 – 2 days per gravimetric system and vacuum feeder (including training)
Winder retrofits for Non-W&H blown and cast film lines
FILMATIC-Winders
Easy processing with a smart design: With a film winder from W&H's comprehensive FILMATIC range, you can offer perfect, straight-edged rolls from start to finish.
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.

Installation
Filmatic winders and components are assembled and installed by W&H service technicians
Installation including training: approx. 5 days (depending on requirements)
Retrofits for Non-W&H cast film lines
Stand Alone FILMEX Extruders
Upgrade your cast film line by retrofitting high performance FILMEX extruders with SMB (Smooth Barrier) screws and crosshole mixing sections.

FILMEX extruders can be retrofitted on all cast film lines, including W&H and others.
Installation
Installation of extruders including all components either by W&H service technicians or by customer.
Installation: approx. 1- 2 days per extruder (including training)
