The FlexiArm has been designed for the rapid installation of the Tappex Trisert and Foamsert Threaded Inserts
The Tappex FlexiArm installation machine consists of a pantograph arm with a Desoutter pneumatic screwdriver attached. The screwdriver can be specified with an automatic reverse torque-clutch control at either 510 rpm or 1,100rpm, or a manual reverse torque-clutch control at 510 rpm, depending upon the size of the insert and the material into which it is being installed.
The FlexiArm provides a low-cost assembly solution for many different post-mould applications and its size allows it to be installed alongside the respective moulding machine, so that inserts can be fitted during the waiting time of a typical mould cycle. It is available with one, two or three arms (which can be fitted at a later date) to suit most multi-task assembly requirements.
A range of production drivers is available to provide an accurate method of installing the inserts at various heights and positions in the moulding (see inset), and they are available separately to suit M2 to M8 threads and also equivalent Imperial sizes.
Tappex also provide a rapid installation tray for use with the FlexiArm and suitable for parts 136, 137, 138, 170, 336, 338 and 040 in a range of sizes from M2 to M6.
Tappex have responded to market demands and developed a new and improved range of 031 Hand Installation Tools for use with the Trisert and Trisert-3 inserts in thread sizes from M2 to M10, these come complete with an alignment bush.
Press-fit tools for the Tappex Multisert range
The Tappex Heat Inserter has been specifically designed to provide reliable and efficient heat insertion of Multiserts in many thermoplastic applications. It is of rugged construction and features a variable feed-back temperature control to suit virtually all grades of thermoplastic and also a speed control to prevent the operator overriding the correct insertion cycle time. An indicator light illuminates as soon as the insert is fully installed.
It has an output of 400w and comes complete with three interchangeable heat tips, for different sizes. Other heat tips are available to order to suit most applications.
Multiserts can be successfully press fitted cold, into the softer and more elastic grades of thermoplastic material, and the Tappex Arbor press has been designed for such low volume cold press fit applications. It provides a reliable and accurate installation, provided a suitable jig is made to locate the moulding firmly in the correct orientation for the inserts.
However for harder grades of thermoplastic, press fitting needs to be assisted by either heating the insert or by using ultrasonics to prevent the plastic becoming stressed which can lead to cracking over time, particularly in thin sections or in long thin bosses.
