KraussMaffei bundles all extrusion technologies under one roof

May 12, 2021 RubberWorld 2182 Views kraussmaffei

KraussMaffei Group has bundled its technological know-how and decades of experience in extrusion by merging its corporate extrusion operations at a single location. This strategic approach results in substantial product benefits for customers, valuable synergy effects for the company, and new opportunities and fields of research for the future. The highlight will be the world’s most modern extrusion research and development center currently built at the company’s new site in Laatzen on the outskirts of Hannover. The new plant is part of the largest investment program in KraussMaffei’s history. The relocation of the entire extrusion division is scheduled for the second half of 2022.

Dimensional Change Resulting From Swell And Drawdown Of Extruded Polymers

March 8, 2021 RubberWorld 3233 Views 2019, extrusion, May

Understanding and predicting how extruded profile dimensions change along an extrusion line contribute significantly to the design of shaping dies and the effectiveness of dimensional control. Upon exiting the extrusion die, the dimensions of nonsymmetric profiles change non-uniformly along the line due to swell and drawdown.

Challenges In Extrusions Met With Branched, High Molecular Weight Keltan 13561C EPDM

March 8, 2021 RubberWorld 3640 Views 2020, arlanxeo, epdm, extrusion, May

Keltan 13561C was introduced as the premier EPDM grade for extruded seals. It has quickly become apparent that the unique combination of the grade’s characteristics makes this material one of the principal tools for other applications. The very high molecular weight and long chain controlled branching drive economical compounding and enhanced processing. Hose formulations can benefit from these characteristics.
