John Winter stocks filters for foundries producing aluminium, iron, steel and copper alloys
The need to produce quality castings has never been so important and metal filtration and cleaning is an essential part of the casting process. Filtering all cast metal production is now standard practise for all foundries and John Winter has a comprehensive range of filters for all metal grades to reduce the risk of inclusions in castings.
​
Cleaning the metal surface prior to casting or using a protective flux is vitally important to ensure the metal is in pristine condition before any metal is poured. For Iron and Steel casting John Winter has Slag Coagulant and Slagcure K and for aluminium alloys and copper alloys a range of fluxes to cleanse and protect the melt from atmospheric moisture.

Filters for:
Aluminium, Copper Alloys, Iron and Steel
Filters for
Aluminium Alloys
AL Filter
The AL Filter is designed specifically for aluminium alloys. The filters can be put back into the scrap and remelted with no detrimental effects from fragments of filters ending up in castings when 'returns' are remelted and recast.
Filters for
Iron & Copper
Alloys
JW Silicon Carbide
High quality, silicon carbide filters supplied to some of the biggest foundries in the UK and globally for casting Grey Iron, SG Ductile iron and Copper Alloys.
Available in 10, 20 and 30PPI and multiple sizes.
Filters for
Steel Alloys
Zirconium
John Winter zirconium filters are tried and tested and in use at multiple steel foundries. The Zr filter is well suited to the most demanding high temperature alloys. Suitable for steel alloys and available in various sizes.
Filtering Aluminium
Large White Alumina Filters
Alumina
Our large white alumina filters are for filtering large volumes of aluminium. Typically used in bulk melting systems, metal refiners and large scale aluminium ingot and slab production.
Available in standard and bespoke sizes with and without gasket.
Aluminium Filtration
Filter Cloth/ Mesh
10PPI & 20PPI
Die Casting Filtration
Filter cloth is available in 2 grades. Fine 20PPI (1.5mm pores) and coarse 10PPI (3mm pores).
Supplied on rolls but can be cut to length.
Ferrous Metal Cleaning
Surface treatment coagulants and fluxes
Cleaning Iron & Steel
Slag Coagulant
Metal Cleaning
A granular coagulant that binds liquid slag together so it can be easily removed from the metal surface. 2 or 3 applications will produce a clean metal surface prior to casting. Available in Fine, Medium and Coarse grades.
Flux
Slagcure K
Metal Cleaning
A blend of oxides that gets added to the ladle or furnace. Helps to prevent liquid slag from solidifying and building up on furnace and ladle linings therefore, extending the service life of refractories.
