Q: WHAT CAN BE DONE TO PROTECT A NICKEL BELLOWS OR ELECTROFORM FROM CORROSION, OR MAKE IT BIOCOMPATIBLE?
A: Depending on the application and media the bellows or electroform will be exposed to, it can be plated with a thin layer of gold or coated with parylene. Gold adds protection against corrosion in all types of climates and environments, and is also an excellent conductor of electricity. Parylene is a polymer coating that provides moisture, chemical, and dielectric barrier properties, as well as dry-film lubricity. Both gold and parylene are biocompatible.
Q: WHAT IS REVERSE BENDING?
A: From the free length, the bellows may be operated in compression and anywhere therein to max compression and up back to the free length, OR, from the free length, the bellows may be operated in extension and anywhere therein up to max extension and back to the free length. Reverse bending is when the bellows is operated in compression and is moved through the free length into the extension and vice versa. Reverse bending will reduce the cycle life of the bellows.
Q: WHAT IS “MUTUALLY EXCLUSIVE” AS IT APPLIES TO OUR BELLOWS DRAWING TABLE?
A:The bellows should not be made to max out all capable movements at the same time. Offset and Bending movements reduces available stroke capability. Contact engineering for specific design requirements.
Q: CAN THEY BE LASER WELDED?
A: Servometer® does not offer laser welding but several of our customers have reported successful leak tight result with laser welding.
Q: HOW LONG DOES IT TAKE TO QUOTE A CUSTOM BELLOWS?
A: Most custom bellows will be quoted within 3 weeks. When we need to request additional performance specifications or review design options with our customers the process could be delayed.
Q: WHAT IS THE LEAD TIME FOR A CUSTOM BELLOWS?
A: On the first order the bellows lead time could be 6 weeks and assemblies 8 weeks. For repeat orders it would be one weeks less.
