Acid Pickling in Hot-dip Galvanizing Processes
1. Acid Solution Control Concentration: Maintain hydrochloric acid (HCl) concentration between 10–20% (or sulfuric acid at 5–15%). Excessively high concentrations accelerate corrosion, while low concentrations prolong pickling time and risk incomplete oxide removal. Temperature: Keep temperature within 20–50°C (ambient to mildly heated). Avoid overheating, as it accelerates acid consumption and hydrogen embrittlement risks. Contamination: Regularly monitor for iron salt […]
Challenges of CNC Custom Plastic Machined Parts
If you think CNC custom plastic machined parts always offered rainbows and butterflies, that’s not the case. In fact, there are a couple of considerations before you go with CNC custom plastic machined parts – and these include, but are not limited to: Warping and Tooling The most common challenge or drawback to it […]
