Frangibolt®

TiNi’s Frangibolt actuators are a simple and effective way to support and release loads up to 20,000 lbf. The operation process is simple as a Shape Memory Alloy (SMA) cylinder elongates to fracture a bolt or stud, thereby achieving separation of two or more components. Standard Fastener sizes range from # 4 size screws to ½″ bolts.

Pinpuller

TiNi’s Pinpullers are fast acting and suitable for a wide variety of Aerospace applications. Pin retraction is achieved by coupling the recovery characteristics of Shape Memory Alloys with TiNi’s patented trigger mechanism. Pinpuller retraction force ranges from 5 to 1,000 lbf with five standard sizes offered as COTS (Commercial Off the Shelf) items.

Ejector

TiNi’s Ejector Release Mechanism (ERM) is a uniquely simple and effective device which offers both high load holding capability and fast actuation time. The Actuator “Coupler” acts as a detachable Nut and can be used to support and release loads up to 4,000 lbf.

Cryogenic Valve

TiNi’s Cryogenic Valve uses a high force piston that is operable at pressures up to 10,000 psi. This may be configured in either a “Normally Open” or “Normally Closed” embodiment. The sealing mechanism is designed to operate with both gas or liquid at temperatures down to -200 degrees Celsius.

Optical Shutter

TiNi’s Optical Shutter was first developed for SwRI (Southwest Research Institute) for the New Horizons mission to Pluto. It provides a simple and effective means to let light into sensitive instruments. The aperture cover is opened on command and can be manually reset to support ground testing.

Shackle Release

TiNi’s Shackle Release was developed for Subsea rigging applications which require support and release of critical payloads remotely. The release function is achieved by using one of TiNi’s subsea Frangibolts coupled to powerful jaws which provide a leveraging mechanism, similar to a pair of pliers. Scalable design allows hold down and release of loads in excess of 100,000 lbf.

Thermal Trigger

TiNi’s Thermal Trigger may be used in a variety of fire safety applications. The enabling technology is the use of TiNi’s SCSMA (Single Crystal Shape Memory Alloy) material which makes it possible to set the trigger temperature at much higher values than is possible with commercially available SMAs.

Cable Cutter

TiNi’s Cable Cutter uses powerful Bellville springs in conjunction with a specially designed blade and anvil to sever high strength stainless steel cables. This is an effective means to release payloads in emergency applications such as Search & Rescue. As with all TiNi products, it is fully resettable and offered in a variety of sizes and embodiments.

Frangivalve

TiNi’s FrangiValve is a “Normally Closed” isolation valve that is capable of supporting pressures up to 10,000 psi. It is hermetically sealed using an all stainless steel valve body with a variety of orifice sizes. Actuation is achieved by using a Frangibolt Actuator to break an internal barrier which bridges the inlet hole to the outlet port. The design is inherently scalable and available in a variety of embodiments and flow rates.

Micro Latch

TiNi’s Micro Latch was developed specifically for “New Space” applications such as hold down and release of Cubesats. It is small in size, fast acting, and a cost effective way to support and release preloads up to 50 lbf.

Auto-Reset Pinpuller

TiNi’s Auto Resetable Pinpullers were born out of space constrained applications where the Actuator is buried deep within a complex instrument. This makes it difficult or impossible to perform a manual reset. Auto reset is achieved by incorporating a secondary SMA actuator which can re-extend the Pin on command and yet not interfere with normal actuation. This is done using a custom flexure made from our patented SCSMA material.

Mini-Frangibolt®

TiNi’s mini Frangibolt is based on a #4 size screw and we believe is the smallest, simplest, and most powerful Actuator (considering its size) available in the world today. Once again, the enabling technology is our SCSMA material which provides 3x the stroke of commercially available SMAs. TiNi has been manufacturing these FD04 size Actuators for Cubesat and other applications since 2005 and can readily scale production to meet commercial demand.

Subsea Ejector (ERM)

TiNi’s Subsea Ejector Release Mechanism (ERM) includes a Pressure Balanced and Oil Filled (PBOF) enclosure such that it can operate directly in Sea water at high pressure. It has been successfully used in many deep ocean applications to deploy critical instruments from various manned and unmanned submarines.

Learn More

Subsea Frangibolt®

TiNi’s Subsea Frangibolts use a polyurethane outer jacket and sealed cable such that they may be used directly in sea water and at very high pressure. As in space applications, the Frangibolt offers a uniquely simple and effective means to release deployables remotely in hostile environments. Standard size Actuators are available for bolts up to ½” which can support and release loads in excess of 10,000 lbf.

Subsea Pinpuller

TiNi’s Subsea Pinpullers have been used in many oceanic projects. Typical applications include deployment of ballasts, buoys, cables, and other items from a wide array of AUVs. Much like our ERMs they include a Pressure Balanced and Oil Filled (PBOF) enclosure such that they can be used directly in sea water at high pressure.

2 Way Optical Shutter

TiNi’s 2 Way Actuator is used as a generic means to push and pull an output Pin in opposite directions. This may be used for functions ranging from Optical Shutters which can Open and Close on demand, to Fail Safe Actuators that require input to enable (or disable) a mechanical system.

Learn More

Gas Cylinder Penetrator

TiNi’s Gas Cylinder Penetrator (GCP) is a simple means to open high pressure cylinders for a variety of applications ranging from venting to emergency inflation to release of breathing air. The Actuator is fully resettable and uses the same mechanism as our high reliability release devices. Our GCP can be configured with a variety of mounting methods, puncture pin profiles, and manifold assemblies.

SCSMA Components

SCSMA raw materials and components are routinely manufactured to support R&D projects. Basic “as drawn” forms include wire, leaf, tube and rod. These may be subsequently machined into more complicated shapes that provide a broad range of functions. These are available in small manufacturing lots with a transition temperature ranging from -150C to +200C.
