FACILITIES
Mini-Flex Corporation in 1965. Current photos will be posted soon.
Brazing (MIL-B-7883) or Soldering- In general, the induction method of brazing or soldering is preferable since there is no danger of torch flames contacting the thin-walled bellows, causing immediate damage or early failure in the end usage. The sub-assembly shown eventually becomes a complete "Bellows-Coupled Rotary Motion Feed-Thru" for ultra high vacuum service.
Welding (MIL-STD-1595) - In most cases, Mini-Flex utilizes the Tungsten Inert Gas Fusion Welding (T.I.G.) process. By using low amperage control, and no filler rod material, the heat can be pin-pointed directly at the weld joint without subjecting the convolutions to high temperature. The miniature assembly shown is 3/8" O.D. and has been tested in excess of 10,0000 p.s.i.g. without deformation.
Quality Control - Due to the inherent critical nature of a thin-walled bellows, MINI-FLEX exceeds the requirements of MIL-I-45208 and MIL-STD-45662. These inspection procedures are consistently maintained for ultimate reliability. This inspection room is fully climate controlled, glass enclosed and separated entirely from all work areas.
Leak Detection - The bellows subassembly illustrated is being tested for leakage with helium on a "Mass Spectrometer Leak Detector". At this stage there have been five silver braze joints completed, of which each joint has been individually checked previously. This is standard procedure at Mini-Flex on all critical leakproof, or ultra high vacuum assemblies. Certification of leak test to 1x10-9 scc/sec. is always available on request.
Custom Designed Bellows Machine (affectionately called the "Monster") - This view of a conglomeration of mechanical, electrical and hydraulic components combine to ultimately allow consistent and sensitive control in the forming of a bellows in order to offer repetitive characteristics at competitive costs.
On-The-Shelf Stock - Mini-Flex Corporation has initiated a "first" in the bellows field - a policy of carrying thousands of these highly specialized items "on-the-shelf". Ideal for prototype and research and development projects.
