1.透气钢热处理
PORCERAX II透气钢的出厂硬度为35-40 HRC，但是如果有特殊需求，本产品也可以处理至HRC50~52度使用，PORCERAXⅡ透气钢的热处理应在真空炉中进行。
2.透气钢硬度
PORCERAX II透气钢的表面25％是孔隙，如果用洛氏或布氏硬度计测试硬度，会给出虚假或误导的读数。采用任何一种施加符合的测试的硬度计，都会使得表面之下的气孔倒塌并呈现一个假阅读。建议使用显微维氏硬度计（50或30克负载）来测量新东透气钢之硬度。
3.新东透气钢蚀纹
PORCERAX II透气钢（7微米级）可以进行蚀刻，但是为了防止破坏的材料的内部的排气结构的，某些程序必须严格遵守。
至关重要的是，应确保加工部门了解透气钢材质以及蚀刻技术，否则可能使得工件彻底报废。透气钢在蚀刻之前，必须彻底清洗空隙并妥善密封，否则蚀纹过程中所使用的腐蚀剂会浸入孔隙结果，生锈并堵塞气孔，这种损害是不可逆的，必须更换新的透气钢工件。
我们建议不要在蚀纹面中插入透气钢，透气钢完美的排气性，会导致插入区域纹理分辨率变高而光泽降低，同时由于透气钢所需要的预处理过程，使得交期延长、成本提高，合理的安装区域会是更好的选择。更多的信息，可咨询你的透气钢供货商。
4.新东透气钢表面呈现
在正确的使用情况下，PORCERAX II透气钢实现了完美的排气，使得树脂和模具成型表面的完美贴合，从而可以产生高质感、哑光的表面。但是如果将透气钢安装在腔侧，起结果将造成纹理设计和实际光泽的差异，不过如果产品成型后会被再次喷涂，则可能是可以接受的。
5.水冷管线
出于尺寸或应用的考虑，偶尔会采取水冷却透气钢工件的方法。有多种方式来实现这一点。在涉及一个直通水管线方案时，密封防泄漏的镀镍水管是有效的。在复杂管路模式中，最好使用可以接受的密封剂，如dichtol。化学镀镍有一点要注意，应当远离尖角，例如那些穿插在水管的交叉点，否则镀镍层会有脱落的可能，最终导致泄露。另外，dichtol密封胶使用不当也会产生相同的结果。请确保透气钢材料已被彻底清除残留的加工液或其他污染物。

Porcerax II
Post-Machining Treatments
Heat Treatment
Heat treating of Porcerax II should be done in a vacuum furnace. As supplied, Porcerax II has a hardness of 35-40 HRC. It can be heat treated to 50-52 HRC; however, Porcerax II carries a fairly high potential for movement. Strict guidelines are supplied by International Mold Steel and should be followed.
Hardness
Porcerax II is 25% porosity by volume and will give false or misleading readings if tested with either a Rockwell or Brinell hardness tester. As the load of either of these testers is applied, the pores beneath the surface will collapse and render a false reading. It is recommended that a micro Vickers hardness tester (50 or 30g load) be used to test the hardness of Porcerax II.
Texturing
Porcerax II (7 micron grade) can be textured. In order to prevent the possibility of destroying the internal vent structure of the material, certain procedures must be strictly adhered to. It is imperative that the chosen texture source know they are working with Porcerax II. If they don't, the likelihood for permanent, irreparable damage to the piece is virtually assured.
The pores of the material must be thoroughly cleaned and properly sealed prior to texturing. Failure to do so results in the etchants used in the texturing process leaching into the pore structure and rusting the venting closed. This rust is permanent and cannot be removed once it has occurred. The piece will be useless and must be replaced.
Thousands of molds worldwide have been successfully textured. However, it is imperative that the molder and/or moldmaker's texture source be supplied with the information needed from International Mold Steel to properly process the piece.
We strongly advise against inserting Porcerax II into an already textured surface. The perfect venting of Porcerax II results in much higher resolution of the grain at the inserted area and a dramatic reduction in gloss. It is recommended that the entire textured surface be Porcerax II. Also, due to the pre-treatment procedure required for texturing Porcerax II, expect longer deliveries and higher costs. Please consult your graining source for more information.
Surface Reproduction
Porcerax II provides perfect venting of all gases from the mold. While this is desirable in most cases, the venting of the Porcerax produces a perfect "marriage" between the resin and the molding surface, thus producing a dull, matte finish. If Porcerax II is used as an insert on the cavity side, the result will be two dissimilar appearances due to differences in gloss and texture definition. This may be acceptable if the parts are painted after molding.
Water Lines
Occasionally the need will arise, due to size or application considerations, to water-cool Porcerax II. There are a number of ways to accomplish this. In designs that involve a straight-through water line pattern, a simple, effective way to seal the line and prevent leakage is electroless-nickel plate the water lines. In complex circuit-type patterns, it is advisable to use an acceptable sealant such as Dichtol. Electroless nickel has a tendency to pull away from sharp corners such as those at intersections of crossing water lines. However minutely this pulling away from corners may be, it will eventually cause some leakage into the material and reduce permeability through oxidation. Improper use of the Dichtol sealant will produce the same results. Regardless of which sealing process is used, be absolutely certain the material has been thoroughly cleaned of any residual machining fluids or other contaminants.
