Can laser cutting or CNC punching on pre-swollen membranes improve hole alignment accuracy in RED stack assembly compared to manual punching, or are there other effective methods available for cutting holes in membranes?
Laser cutting or CNC punching on pre-swollen membranes can improve hole alignment accuracy in RED (Reverse Electrodialysis) stack assembly compared to manual punching, as they offer:
1. Higher precision (µm-level accuracy).
2. Better repeatability for uniform hole patterns.
3. Reduced deformation vs. manual methods.
Best choice depends on material, swelling behavior, and production scale. CNC/laser is optimal for lab/prototyping; die cutting suits large batches.
Thank you for the clarification. I have one more question:
Can you please suggest a suitable gasket material for my RED experiment? Currently, I am using EPDM gaskets and platinum-cured silicone gaskets, but they tend to expand under compression, causing the holes to misalign.
Is Teflon (PTFE) a better option, or would you recommend any other material for the gasket? Please advise.
I am using FAS-30 and FKS-30 membranes. For making holes in these membranes, is laser cutting or CNC punching a better option, especially considering that the membranes will be in a wet, fully expanded condition?
