There are two times cleaning must to be performed to Vortex® and Porcerax II®:
The first time is when the tool shop has prepared the insert or cavity. The material is 25% air by volume and the cutting fluids will displace the air, thus filling and clogging the pores. After the permeability has been restored by EDM machining the venting surface, the steel should be sent to Molder’s World, Inc for professional cleaning.
The second time cleaning is needed is after the insert or cavity has been in operation and film, a thin layer of mold release agent, resin residue, shop oil or any other contaminate has partially or totally blocked the air flow.
