The Tappex HiMould range of brass inserts has been designed as a technical improvement on the superseded Yardley style of threaded insert, specifically for moulding-in during the cycle of the moulding machine to provide the maximum performance.
The Tappex Multisert range of brass inserts for plastics has been developed to provide a multi purpose insert for various environments and applications. They are available in Short and Regular lengths both Unheaded and Headed.
The Microbarb incorporates all the standard features of the Multisert range but provides the designer and production engineer with a brass insert suitable for pull through applications in thin section materials. The performance offered by the larger diameter and head offsets the shorter barb length when compared to the equivalent Multisert.
Self tapping brass insert for use in Thermoplastic and Thermoset plastic materials. The concept of the Tappex Trisert design is to provide a reliable and efficient post-mould production process, where the installation torque can be controlled and monitored for increased reliability.
The Tappex Trisert-3 has three cutting features to provide a balanced cutting action and reduced installation torque. The Trisert-3 is suited for critical applications and is available in two lengths, regular and long, and is based upon the Trisert Reduced Headed design.
The Tappex Foamsert is a special version of the Trisert and has a very coarse truncated external thread form. The Foamsert threaded insert ideally suited for use in structural foam materials, laminated chipboards, medium density fibre board and certain types of glass reinforced plastics.
Threaded insert designed for cold press installation into hard and filled thermoplastic and thermoset plastic materials. Available as a Single and Double Ended brass insert.
Threaded insert designed for Ultrasonic or Heat installation into notch sensitive thermoplastics. The double ended design is easy to orientate for manual or automatic installation.
Press fit, Self Tapping or Mould-in For Plastics. Tappex offer a range of Male Inserts based upon the female equivalent, they can be supplied with a dog point to ease location of the nut and reduce the risk of cross threading.
If there is not a standard Tappex insert, which suits your application, you may well find that there is already a 'Special' Tappex insert available that is suitable.
Anti-creep spacers are designed to provide reinforced clearance holes for bolts to pass through a plastic moulding, and thus allow metal-to-metal clamping forces to be applied to an assembly without over-stressing the plastic.
Universal Fastening System. The Grooved Pin range has provided fastening solutions in a number of industry sectors including: machine building, chemical equipment, manufacture, precision engineering, automotive and electrical engineering.
Tappex are extending the range of male inserts for moulding by introducing the SplayMould® male steel insert. Often customers expect to be able to apply standard tightening torques at the point of assembly and in application to enable existing equipment and set ups to be utilised. The Tappex SplayMould® offers a high strength solution.
The Dedsert design includes two bands of helical knurling with left and right helix providing high performance.
Tappex can manufacture most Imperial thread sizes using the external features of the nearest metric equivalent product, so design information will be the same as listed. Popular sizes are available from stock; other sizes are available to order in reasonable batch quantities.
Tappex TPX screws are produced by cold forging, not machined from bar or wire and therefore have good inherent mechanical properties with minimum residual stress material into which it is being installed.
The Rivet Nut is designed with four holes to control the deformation of the body. This property enables the use of Rivet Nuts in applications and materials where they would otherwise not be suitable. They are available in a range of materials, grip ranges and in headed and reduced head styles.
Tappex offers a range of Installation Equipment for small to medium volume applications. Designed to be adjustable and flexible, with the ability to be adjusted or modified to suit a number of insert sizes and wide variety of installation conditions, the equipment will be useful beyond the application for which it was purchased.
