Examples from the field
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
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.
Replacing the existing W&H 3-layer die with a compact MAXICONE C with MULTICOOL P2K
Investing in MAXICONE C with MULTICOOL P2K has improved the customer’s ability to serve the market and has increased efficiency. Apart from higher outputs and better film thickness tolerances, when determining the layer ratio, the customer is awarded increased flexibility and production, compared with the old system.
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.
Extending the existing W&H Profile control with the PROFILE BOOSTER Module
Significant scrap caused by frequent resin and recipe changes was reduced using this module because the PROFILE BOOSTER shortens start up time until good quality product is achieved by up to 60%.
Modernization of the haul off with MULTINIP with patented drive concept and NOSTIC film control
Film curvature and slack caused downstream converting problems. Upgrading the line with the extremely long collapsing frame of the Multinip haul off in conjunction with the patented NOSTIC film control solved the problem.
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Unsatisfactory operation, poor winding quality and lack of operational safety of the existing, outdated winder prompted the customer to do something about it.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.
