Tylaska Marine 自1955年起开始生产高品质快脱卸扣，至今已经广泛使用于航海业，是世界最顶级的卸扣制造商。
Tylaska Marine is located in Mystic, Connecticut, a town historically known for sailing and whaling. Sailing has been a heritage of Mystic for hundreds of years, so it is fitting that new products for the sailing industry originate in the same location. Tylaska Marine began producing high quality snap shackles in 1995. The original shackle evolved from a need to build a quick release mechanism for detaching towed gliders from behind power boats. At the bequest of interested sailors, the design quickly transformed into its present configuration now popular with the sailing industry. Over the years, several other products followed to complement the initial snap shackle. All of the shackles and their components are made right here in Connecticut by Tylaska’s team of dedicated workers. Everything is made in the USA; Tylaska Marine is one of the last manufacturers able to make this claim.
Unlike many other manufacturers, Tylaska pursues a different product mission. Instead of looking for ways to cut corners and skimp on quality, Tylaska shackles are aimed to be the best possible product made based upon physics and not economics. Many extra and exotic processes are used differentiating the Tylaska shackle from the normal piece of hardware.
First, every structural part is run through a procedure called hipping (high isostatic pressurization), which is a process normally only reserved for spacecraft and critical aerospace parts. This consists of heating the component to near melting point in a vessel containing inert gas. The gas is then pressurized and the softened component is squeezed and compressed to seal and collapse any underlying void or imperfection. The result is a very dense and uniform material similar to a wrought or forged component, but in a shape or configuration impossible with forging.
Next, heat treating is done in vacuum furnace to eliminate any chance of contamination. Several testing processes are implemented such as zyglo and magnifluxs to identify any microscopic surface flaws or cracks that could go unseen by the unaided eye. Each component is then run through a salt corrosion test to identify any contamination or chance for staining and ultrasonically cleaned afterwards. Next, each and every snap shackle is tension pulled to 50% of its breaking strength and also released under load. This is not a random statistical process, every single snap shackle is pull tested and verified as to holding the stated working load.
After proof testing, the shackle is hand buffed and then cleaned again. Finally, one last thorough hand inspection is done on each item to verify that nothing is left unchecked. The result is a shackle that could pass as a piece of jewelry and exceeded the specifications for a part used in the space shuttle.
Tylaska shackles are not the least expensive, but they are quite possibly the best. Some people may call it overkill but we call it security and peace of mind for applications where failure is not an option.
