Machined springs overcome wound limitations
For those engineers familiar with the traditional wound spring format, Abssac is offering a new way of looking at reliability, performance and attachment by use of a machined spring.
Electrodeposited metal bellows come to the UK
Abssac now supports the full range of unique electrodeposited metal bellows and electroformed products available from the Servometer Corp as its newly appointed sole UK distributor.
The insert is available in two grades of stainless steel and also in case hardened steel with an electro-plate finish.
The standard Trisert range includes double-ended, reduced-headed and regular-headed variants.
These suit most applications in thermoset and thermoplastic grades, including the latest engineering plastics.
The Trisert design provides a reliable and efficient post-mould process, where the installation torque can be controlled and monitored for greater reliability.
As the internal thread is used to install the Trisert, every insert is automatically checked in the moulding for the existence of a good thread.
Trisert-3 has three features that provide more balanced cutting forces and therefore reduced installation torque compared to the many cross-slot designs available, whichonly have two cutting features.
The Trisert-3 has complete cylinder design, providing a stronger body, size for size, than the slotted design and allowing it to be used in pull-through applications without any problems due to increased assembly torque associated with slotted inserts.
Trisert-3 is available in two lengths - regular and long - and is based upon the Trisert reduced-headed design.
This provides an increased bearing surface that not only higher tightening torques to be applied and provides more support to softer mating components.
The head diameter is designed to exactly fit the counter bore in the moulded hole and thus presents a neat, flush-fit finish.
Trisert-3 is offered in two grades of Stainless Steel (303 and 316) and also in case hardened steel with a zinc nickel, trivalent passivated finish.
The new Trisert-3 can be rapidly and reliably installed using Tappex' FlexiArm machine, which consists of a pantograph arm with a pneumatic screwdriver attached.
It is available with one, two, or three arms to suit most multitask assembly requirements.
