Our History

July 1995

Twins s.r.l. was founded this year.

The company was initially responsible for consultancy and projecting on behalf of external companies operating in the testing and assembly industry

December 1996

The "P16" unit was provided with an automatic load/unload system, which worked locally. It could be connected to assembly machines or directly inserted in a production line as a test station.

As a consequence, the production of small assemblies or operations complementary to the testing phase, such as tuning, marking, staking, screw driving, etc. was finally possible.

Some P16L units, with this particular equipment, reached the production of 1,300 pieces per hour


The A36 unit became a numerical control machine. The innovations introduced were the bench now being able to execute the change of equipment at zero time, the time needed for the rotation of the bench reduced to the least and the bench itself which could now be configured for anything between 6 and 36 stations by simply changing the program.

The project of combining the components together finally allowed for the P16L and the A36 units to be paired enabling it to create actual production lines by using the same modules at all times.


The TV16 unit, nicknamed "the television" was born. This testing unit was conceived for usage within a laboratory or to replace obsolete testing systems when a high productive performance or the fitting of additional testing units complementing the tightness tests is required.


The TFX6 model, an up-to-date TB400 base version of the old P16L machine was released.

All the components are now combined together and are fully interchangeable between the machines and the Twins units


For the last 4 years Twins srl has been adopting a process of continuous improvement whose aim is to simplify the maintenance operations, convert all parts into components available worldwide as well as train all our engineers according to clearly defined procedures.

This process has allowed us to manufacture our machines not owing to "highly qualified" staff but simply thanks to a "method of work" which can easily be reproduced, thus enabling even our clients' staff to intervene with the greatest ease on all those machine parts which require regular maintenance.

Besides this, we constantly invest in all the new technologies available which enable us to reduce the lead time and improve the competitiveness of the product.

January 1996

In 1996 the Test Station "Twins P16", nicknamed "the washing machine" for its resemblance to the well known household appliance, was produced and commercialized. It remained available on the price list until August 2000, having tested the largest variety of items, from gas regulators to water meters and pneumatic electric valves, all produced on the same unified base.

The "twin" Test System, which gained great success, allowed simultaneous testing on a station, while the other one was loaded or unloaded.


The A36 unit was born. The testing phase got more and more combined with assembly operations, thus it became necessary to utilize a robust and highly configurable machine which could successfully carry out complete assembly sequences, as well as dealing with the testing and tuning phases.

The choice to have the units fitted at the centre of the bench was an excellent move as regarded the load of the work being done as well as easy access to the whole tools set.


The "washing machine " went out of production and was replaced by the TB400 test module, better suited for the new safety and environmental directives. Being faster and more flexible during the testing phase, it is in fact capable of carrying out the testing of a different piece for every station.

The number of available stations increased to 4 and could now be equipped with all the A36 unit accessories, among which the numerically controlled handling units. The loading interface by ROBOT became a built-in standard.


In 2002 the TBR8 unit was born, a TB400 unit fitted with a fast rotating CNC bench capable of completing a rotation movement in less than 0.3 seconds, a feature that caused the unit to be nicknamed "the helicopter"

With this unit too, like the A36 model, using a rotating CNC bench allows the change of the equipment in zero time.

As for the operations of testing and turning, the TBR8 was now able to produce 2,400 pieces per hour and that was just the start of its career…

It is fitted with a load/unload system (a CNC system) which operates at a pace of 2 seconds for a piece change from the bench to the line and 1.2 seconds for a change between the feeder and the rotating bench.

Fitted with 4 stations, it may feature up to 4 pieces of equipment always available at zero change. A maximum number of 8 stations are available, with two pieces of equipment always available for the fast piece change. Alternatively, 16 stations are available without fast piece change.


The TB1 model was born, a single testing station to be combined with production machines or inserted in manual assembly lines.

It has been intentionally built without a ground basement in order to be better inserted on the work platforms.
