Vehicle interiors, exterior plastic-trim components and ‘under bonnet’ sub-assemblies (typically manufactured from injection moulded, vacuum formed or composite lay-ups) all require the application of Tappex® fastening solutions: Himoulds®, Triserts®, Multiserts®, steel threaded inserts for metal-alloys Trisert-3® . Additionally, Tappex also manufacture Compression Limiters which reduce the effects of ‘creep’ in thermoplastic mouldings, over time / elevated temperatures by providing ‘metal-to-metal’ contact along the axis of the bolted-joint and so resisting excessive application-tightening torques & resultant assembly joint-loads
Under bonnet thermoplastic / composite material applications: injection-moulded manifolds, covers, ECU & fluid-pump enclosures. Often these applications require higher tensile strength performance from mechanical fasteners to cope with point of vehicle assembly installation torques. Tappex solution: forged steel SplayMoulds®installed by moulding-in and specified to 8.8 grade tensile strength
OEM body-in-white / driver controls / Electro-mechanical assemblies are frequently specified with Tappex® threaded inserts for thermoplastics and, for more critical applications, patented Trisert-3® family of steel threaded inserts. Tappex® offer also to ‘vision sort’ fasteners using bespoke optical / laser-based equipment.
Aerospace
Demanding, precision-engineered solutions, from Tappex® typically as a tier-2 / 3 component supplier, for a variety of aircraft applications including: business & 1st-class seating, toilet & kitchen installations that use composite glass & increasingly carbon-fibre, laminated constructions – Tappex®Trisert-3® stainless steel threaded inserts (303 & 316 grades) in either metric or imperial threads
Bespoke customer specifications supplied also include 2D & 3D rapid prototypes, design guidance & in-house mechanical tests supporting the specification of threaded inserts even for satellite-equipment hardware applications
Consumer Goods
Sometimes referred to as ‘brown & white’ goods; typical applications for brass threaded inserts
Tappex® extensive range of brass threaded inserts for thermoplastics includes: for moulding-in HiMoulds® , self-threading Triserts® and Thermserts® for post-mould, ‘quick fit’ press-in installation
Electronics
Serving both OEM’s and their contract moulding / sub-assembly manufacturing operations
Tappex® can support low volume applications with its comprehensive range of brass thread inserts: HiMoulds®, Multiserts® or Triserts® along with bespoke Tappex® installation tooling for either manual or semi-automated placement (Electrically or Pnuematics activated)
Machine Tools
For many years Tappex® have supplied both brass female and male threaded inserts for Thermoplastics ‘compression-moulding’ whether in-mould or post-mould application
For critical industrial / hydraulics / rotating machinery applications with a background of high vibration, Tappex® Pin-Lok steel threaded inserts offer features to ensure no loosening and maximum security when installed
Parts for safety critical applications are often ‘vision sorted’ to check compliance with customer specific size / feature requirements
Tappex® Threaded inserts are specified in metric, unified and also British Standard forms i.e. BSW/BSP/BA
Marine
Whether for commercial, rescue, leisure or submersible-craft, Tappex® provide high-quality fastening solutions, backed up by comprehensive ‘in-house’ technical knowledge to meet the application demands: interiors, structure or external-mounted equipment
Specifically Trisert-3® threaded inserts in either 303, 316 grade stainless steel and now Titanium (Ti5 grade) for exterior fitments / installation; brass inserts Multiserts® for navigation buoys & boat-interiors,Foamserts®self-threading inserts for interior wooden furniture and trim items, as well as the MultiRiv® Rivetnut designed for composite-materials & GRP panels (low force/wide grip-range rivetnut)
Medical Equipment
We supply both brass & stainless steel (303 & 316 grades) press-in and self-threading brass & stainless-steel thread inserts for plastics to SMC processors, for example:
‘Body scanner’ applications
‘Ventilator equipment ‘ used for: anaesthesia delivery; airway management; suction control and oxygen therapy.
Tappex® thread inserts are specified for RIM moulding processes; both standard & customer-special threaded inserts are available as well as for 2D & 3D rapid prototyping
Motorsport
For exacting performance requirements & technical support, Tappex® serve many different motorsport categories including Formula One with threaded inserts (now including high strength / low weight variants machined from Titanium), compression limiters and special rivet nuts
Whether for composites, vacuum-form, GRP, machined thermosets, light metal alloy constructions and increasingly 2D & 3D rapid prototypes, Tappex® threaded inserts have been the professional choice for over 30 years
Rail
Composite panels and infusion moulded bespoke parts fastened with Tappex® in-mould and post mould brass threaded inserts; passenger carriage furniture is frequently specified with our brass Foamserts® thread inserts for woods and high-density foams alike
Interior packaging, passenger carriage constructions, window frames and door/access (aluminium fabrications), fastened by Tappex® thread inserts, engineered for reliability and long life including Trisert-3® thread inserts in both case hardened steel & stainless versions (metric sizes 3 – 12mm along with unified & male geometry variants)
Telecommunications
Many global customers and network’s applications served by Tappex® for injection-mouldings, aluminium die-castings, aluminium machined parts (equipment racking) as well as GRP enclosures being fastened together with our brass Triserts® & stainless steel Trisert-3® thread inserts
Both on the ground and in satellite orbit around the earth, Tappex® thread inserts are to found holding vital functional parts together in demanding & occasionally remote environments!
