FAQ

• Q1: What is the advantage of using etched plates over machined plates for PCHE?
  A: Etching produces burr-free, stress-free, and uniformly smooth channels without heat-affected zones. It also allows for much finer channel geometries (as small as 0.03mm) than traditional machining, and design changes are quick and inexpensive since no hard tooling is required.
• Q2: What materials can you etch for PCHE plates?
  A: We can etch stainless steel (SUS304, SUS316, SUS316L), titanium (Gr1, Gr2), Inconel, Hastelloy, copper, brass, and many other alloys commonly used in high-performance heat exchangers.
• Q3: What is the minimum channel width you can achieve?
  A: We can achieve channel widths as small as 0.03mm and ridge (wall) widths down to 0.015mm, depending on material thickness.
• Q4: What is your typical lead time for PCHE prototype plates?
  A: Prototype samples typically take 3–7 working days after design approval. Mass production lead times are 7–15 working days, with expedited options available for urgent orders.
• Q5: Are your etched plates ready for diffusion bonding?
  A: Yes. Because etching produces clean, burr-free, oxide-minimized surfaces, our plates are ideal for direct diffusion bonding or welding without additional surface preparation.
