7 Möglichkeiten, ein Industriegehäuse abzudichten

Der Abdichtung eines Industriegehäuses wird selten große Aufmerksamkeit geschenkt – sie ist aber fast immer eine der kritischsten. Welches Dichtverfahren technisch und wirtschaftlich sinnvoll ist, hängt vom jeweiligen Anwendungsfeld ab.

Entgraten von Gummiformteilen

Das Entfernen des Grats kann manuell, thermomechanisch, durch Reibung oder werkzeuggebunden erfolgen. Wenn Gummi entgraten werden soll, stehen damit grundsätzlich vier industrielle Wege zur Auswahl.

Werkzeugkosten in der Fertigung von Gummiform- und Verbundteilen

Anyone involved in the production of elastomer moulded parts eventually faces a central question: What does the tool cost? The answer to this is rarely straightforward.

Isobutene-Isoprene Rubber

Butyl rubber, chemically „isobutene-isoprene rubber“, abbreviated IIR, is a synthetic elastomer distinguished by its very low gas permeability and its resistance to oxygen, ozone, and many other chemicals.

FVMQ – Fluoro-Vinyl-Methyl-Silicone Rubber

FVMQ is a further development of classic silicone. Due to the structural change of the rubber with a fluorine group, fluorosilicone exhibits significantly better oil and fuel resistance while retaining the properties of standard silicone.

HNBR - Hydrogenated nitrile butadiene rubber

HNBR (hydrogenated nitrile rubber) is characterised by its high resistance to temperature, oil and ageing. Overview of structure, properties & processing

VMQ - Vinyl-Methyl-Siloxane

VMQ (silicone) - material properties, terminology (MVQ, LSR, RTV, FVMQ), standards & guidelines, processing and material comparison

CNC milling and EDM

CNC milling and die-sinking EDM in toolmaking: Functionality, differences and interaction between the two processes and their influence on precision and quality.

Additives

Additives in elastomer compounds control processing, ageing resistance, cross-linking and functional properties. Overview of mechanisms of action, additive classes and technical classification.

Primer

How can rubber be bonded to a substrate (metal)? Basics, function and process reliability for primer application.

CR - Chloroprene

Chloroprene (CR): Properties, chemical structure, processing, relevant standards and material comparison with other synthetic rubbers explained in compact form.

NBR - Nitrile Butadiene Rubber

NBR (nitrile butadiene rubber) is an oil and fuel-resistant synthetic rubber characterised by good mechanical properties and high resistance to mineral oils.

FKM - Fluororubber

FKM refers to fluorinated elastomers with a saturated polymer main chain. Overview of chemical structure, processing, standards and material comparison.

EPDM - ethylene propylene diene monomer

EPDM is a synthetic rubber based on ethylene-propylene. Overview of structure, properties, processing and categorisation in a material comparison.
