Molds for injection and rotational molding and profile, film and sheet extrusion will glint in the artificial light inside Messe Dusseldorf's huge halls. Each K fair is a showcase for companies that specialize in making molds for sale to processors, such as:
Canadian die maker Brampton Engineering Inc. (Hall 15, Stand C9) will, after years of keeping the die design secret, open up the inside of one of its proprietary streamlined coextrusion dies (SCD) for K visitors.
The technology gives superior streamlining of melt flow, isolation of temperatures and a simple die design that allows later modification to add more layers, according to Brampton Engineering.
The company also will show Dial-A-Gap, said to change the nominal die gap of a blown film line in seconds.
Visitors will see the company's proprietary process to eliminate curl typically found in blown, asymmetrical coextruded film structures, plus a Windows version of its Italycs control system.
Cloeren Co. (Hall 13, Stand D01) will show an Epoch III AutoGauge Die for making cast stretch film and case polypropylene film.
A ``fixed geometry multilayer feedblock,'' designed for making film with as many as five layers, also will be shown.
An 84-inch die for extrusion will be shown, featuring Edge Bead Reduction technology with motorized, adjustable internal deckles.
The U.S. company claims to be the only flat die maker to use computer numerically controlled milling machines extensively.
After three years of devel-opment, MDM Multi-Colour International (Hall 1, Stand 4-9) will unveil its liquid color manifold, which the company claims can replace machines with multiple injection units.
The manifold is installed directly onto the mold. The company will demonstrate this type of molding in its booth.
The English firm makes molds and the liquid color manifolds.
Kelch Corp. (Hall 2, Stand E1), a U.S. company that claims to be the world's largest producer of cast aluminum molds for rotational molding, will exhibit with its European li-censees, Maus GmbH of Germany and Persico SpA of Italy.
Kelch said it hopes to demonstrate the benefits of rotomolding to people not yet familiar with the process.
Extrusion Dies Inc. (Hall 8, Stand B01-1) will show a surface treatment that protects flat dies and downstream rolls better than conventional coatings, the company claims.
The surface treatment is available as Ultrachrome II for chrome-plated surfaces and SRC (Surface Release Coating) for unplated metal. The product creates a hard, heat-resistant coating that resists the buildup of residual polymers and make it easier to clean polymer that does accumulate. EDI is a U.S. company.
