Case Studies

Transdermal Darts

Here is an example of how the depth and breadth of processes at Peridot benefited one of our clients.

The product pictured here is a transdermal cetacean tag. The product is used to affix an electronics package to large whales for animal studies. Transdermal cetacean tags are deployed either using a pneumatic air gun or a long fiberglass pole. The device is used to study whale behavior and can measure, record and transmit data such as light, depth, temperature, and speed. Peridot’s role was to fabricate and assemble the metal package which houses the electronics.

The assembly consists of a broad head and shaft for ease of penetration.

This sub-assembly consists of a CNC turned shaft laser welded to a CNC Milled and Ground head. Note the 3 tiers of spring fingers.

The spring finger’s configuration result in the device lodging safely and firmly into the animal’s dorsal fin without pulling out. The spring fingers were laser cut and then formed in several CNC press brake operations. The entire system is comprised of bio-compatible materials common to medical devices.

The assembly consists of 7 custom components and a handful of off the shelf screws. The fabrication process list was as follows:

  • CNC Laser Cutting
  • CNC Press Brake Forming
  • CNC Swiss Screw Machining
  • CNC Laser Tube Cutting
  • CNC Milling
  • Form Grinding
  • Laser Welding
  • Mask and Beadblast

Prior to discovering Peridot this client had as many as five separate sub-contractors involved for each order and had to assemble in house. Often the components would not fit together properly and required rework to facilitate assembly. Delays in a single component resulted in our customer being unable to ship final product to the end user, the field biologist. Peridot’s complete supply chain solution took the pain and hassle out of the production of this device.
