Ø 3-28 mm PM-35 Steel Round Rod Ventilated Breathable Steel Bar for Plastic Mould 
It is made of fine particles of spherical powder stainless steel after high temperature sintering, and the inside is evenly covered with tiny vent holes in all directions. It is also called porous material or porous metal.
The specific gravity is small, but the specific strength is high. Good energy absorption. Good vibration damping effect. Large specific surface area. A quarter of the tissue is through holes. It has good mechanical cutting performance and acid and rust resistance.
It has been widely used in the exhaust system for plastic molds and in pressure-reducing equipments.
