Starting Up

Your Business In Brief - September 2008
Husky to De-Emphasize Large-Tonnage MachinesHusky Injection Molding Systems Ltd., Bolton, Ont., says it will de-emphasize production of large injection presses in order to concentrate on its core packaging markets, including PET preforms, closures, and thin-wall products.

Your Business Pricing Update - September 2008
Commodity resin prices were still rising last month, and still more hikes were pending, but market resistance was building.

The lightweighting advantages of in-mold labeling in times of soaring resin costs are highlighted by the experience of Germany’s largest mustard maker.

Don’t Wind Wrinkles Into Your Film
Wrinkles are a major cause of defects in extrusion winding and converting, especially with thinner films, which are much more wrinkle-prone than thick ones. The cause of most wrinkles is located close to the roller where the wrinkle first appears and can be identified by looking at the orientation and pattern of the wrinkle. First, find the cause; then try to eliminate or at least reduce it.

What Toolroom Maintenance Supervisors Need to Know
Those in charge of keeping molds reliable and production-ready normally start their day in the same manner—wondering what broke down since they last walked out the door—and hoping they have the resources to get it going again.
