Gas permeable steel
Mold core with positive air permeability
The metallographic structure (ESEM) of the porous die steel is randomly distributed with a large number of 3D inter-spaced holes.Material: EM191 (S136 / 1.2083) Pore diameter:0.03-0.05mm (normal delivery) 0.01-0.03mm (slightly longer) The pore is an irregular honeycomb shape.
Air permeable steel is a kind of fine-grained spherical powder stainless steel which is sintered at high temperature. The interior is uniformly filled with tiny vent holes, also called porous materials or porous metals.
The air permeability is good, and the cast surface is clear.The filling resistance is reduced, and the filling power can be reduced.The mould clamping force can be reduced.The weight of the mould can be reduced to only two thirds of the original, saving materials.
Custom-made product:
According to the shape of the part, leave a 0.8-mm margin of fully permeable steel on one side, and make regional permeable steel printing and solid steel printing according to the air trapped area of the part.
