ALWA POR STEEL
- is made of steel and a resin binder (in specific cases a stainless steel version can be delivered).
- is porous and produced as a block or slab in our factory in Gronau, Germany.
- has a very smooth surface with good porosity.
- is machinable (e.g., grinding and polishing).
- is particularly suitable for injection mould and blow moulds venting.
- prevents compression resistance. The injection moulding material spreads better in the wells.
- can be cleaned with methyl ethyl ketone (MEK)
- is an economic alternative to expensive sinter plates
- is suitable for: thermoplastics, reaction injection moulding (RIM), rubber

Please consider the different thermal coefficients of linear expansion if ALWA POR STEEL is screwed on a slab or something is screwed on ALWA POR STEEL (slab, block or mould). Drill larger holes for the screws into the material, so that the different expansion coefficients can level out. Screw connections which are used several times should be equipped with threaded sleeves.
