Repair compounds to fill casting defects and pinholes

The absence of pores in metallic cast materials is of great importance for their overall load-bearing capacity. Even the smallest irregularities can lead to hairline cracks or breakage of the component. Unfortunately, these defects often only become visible after machining. The financial losses due to machine and personnel costs can be considerable - not to mention the time delay.

There is actually no classic “metallic” repair method. The only option is synthetic fillers. We explain how to choose them correctly . . . for cast steel, gray cast iron, cast aluminum or gunmetal!

Ask us about: fill porous castings, coat forming tools, repair sealing surfaces, restore guideways, repair leaking housings, seal oil sumps

MetaLine Series XL – MetaLine Series XL are synthetic ceramic metal substitute materials solidifying without shrinking and bulging. Insufficient dimensions, faults, porosities or eruptions may be planed accurately fitting and permanently. After application and solidification exact forming of finished surfaces by means of popular machining methods is possible. With the help of a copper conductive coating applied partially, galvanic further processing of components is also possible.

Scope of application:

Fill porous castings
Coat forming tools
Repair sealing surfaces
Restore guideways
Repair leaking housings
Seal oil sumps

Technical solutions in detail

MetaLine Series XL –

MetaLine Series XL are non-shrinking, non-swelling, synthetic ceramic "metal substitutes". Undersize, imperfections, porosities or break-outs can be accurately and permanently levelled. After application and curing, the treated surfaces can be precisely machined using standard machining techniques. Further electroplating of the component is even possible with the aid of a partially applied copper conductive layer.

More than just optical repairs - solutions that are also used in the OEM sector!

Wir lösen Erosionsprobleme an Ventilatoren / Gebläsen!
Casting porosity repair - there is the need for “invisible” casting defect removal and the need for pure “sealing”. Here is an example of the latter, namely the full-surface coating of a larger casting with the brushable MetaLine repair ceramic KXL
Removal of casting porosities - forming tool in a press shop for the production of automotive parts. Repairing the cavities is just as essential as removing them by grinding or milling. Simple “ filling” is no longer possible with this size and load . . .
Filling casting cavities - the imperfections were professionally processed, filled and scraped to size. Also an effort, but significantly less than a complete new production of the part
Porosity filling - the expert immediately recognizes that it is erosion/cavitation and not a cavity. However, the solution is the same as for porosity caused by casting. Synthetic regeneration with the ceramic-based MetaLine SXL
Ceramic filler - The type of leveling is a typical “do-it-yourself” finish. The professional would shorten the edge length. Not bad - but unfortunately not ideal either. Why are we showing it anyway? So that YOU can learn from it. Where else on a website is someone so critical of themselves?
Filling shrinkage cavities - if the number of porosities becomes excessive, the only option is a complete overcoating. However, this should always be the last option, as the metallic surface character will of course change completely!
Flange porosities - the removal and filling of superficial porosities always requires mechanical preparation, capillary cleaning and drying. Everything else is make-up!
Oversize repair - compensation of flange porosities with the paste-like MetaLine repair ceramic SXL or the brushable version, the MetaLine repair ceramic KXL - depending on the condition of the substrate
