Applications

Automotive

  • Vehicle Interiors,Exterior Plastic moulded parts and sub-assemblies (whether Injection moulded, Vacuum Formed or Composite layups) - Brass Thread inserts: Himoulds®,  Triserts®, Multiserts®  (M1.4 - M12 standards), Steel threaded inserts for metals (M2.5 - M30) & Compression Limiters (usually customer specified to reduce effects  of 'creep' in Thermoplastic mouldings when subject to high-tightening torque/clamp or assembly joint-load applications by providing metal-to-metal contact)
  • Under bonnet plastic / composite material applications - glass-filled thermoplastics & thermosets: injection-moulded manifolds, covers, ECU housings ofeten require higher tensile strength performance from mechanical fasteners. Tappex solution: forged steel SplayMoulds®  installed by moulding-in or heat-installed provide greater tensile strength to cope with point of assembly, higher torque levels
  • BIW / Driver Controls, electro-mechanical assemblies for OEMs globally are frequently fastened by Tappex brass threaded inserts and, for critical applications,  Trisert-3® patented steel(s) thread inserts(M3-M12 now), often specified as 'vision sorted'; Tappex have made invested in the purchase of bespoke Optical / Laser based equipment to check the compliance of the key features of their threaded inserts to suit critical applications also. Tappex 100% wash all machined components prior to packing

Aerospace

  • Demanding, precision-engineered solutions for a variety of applications including: Seating, Toilet & Kitchen installations - Tappex stainless steel Trisert-3® threaded inserts (303 & 316 grades, M2 - M12) in either Metric or Unified threads and/or special Rivet nuts are available designated MultiRiv®  with 'bulge control' performance    
  • Bespoke customer specifications achieved with prototypes, design guidance & in-house mechanical test supporting the specification of Threaded Inserts even for Satellites

Consumer Goods

  • Sometimes referred to as 'Brown & White' Goods; typically Brass threaded inserts 
  • Tappex threaded inserts for plastics with both HiMoulds® for injection moulding application and brass self-threading Triserts® inserts or Thermserts® for post-mould, 'quick fit' installation into thermoplastics

Electronics

  • Serving both OEM's and their contract moulding and sub-assembly manufacture
  • Low volume applications may specify Brass thread inserts: HiMoulds® (In-mould installations), Threaded inserts Multiserts® or Triserts®     (Post-mould / machine installations) insertion with availability of bespoke Tappex installation tooling

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' Machinary 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 Commericial, Rescue,  Leisure or submersible-craft, Tappex®provide high-quality fastening solutions, backed up by extensive & 'in-house' technical knowledge to meet the application demands for the vessels interiors, structure or external-mounted equipement used on Oceans, Rivers or Canals
  • Specifically Trisert-3 threaded inserts in 316 grade Stainless Steel for exterior fitments, Brass inserts Multiserts® for Navigation buoys, Foamserts® self-threading inserts for interior wooden furniture and trim items, as well as our MultiRiv® (Rivetnut) for Composite & GRP panels

Medical Equipment

  • We supply both Brass & Stainless Steel(303 & 316 grades) press-in and self-threading Brass & Steel thread inserts for plastics to SMC processors, for example, 'Body Scanner' applications
  • Tappex® thread inserts are specified for RIM moulding processes; both standard & customer-special threaded inserts are speciifed

Motorsport

  • For exacting performance requirements & technical support, Tappex® serve many motorsport categories including Formula 1with Threaded Inserts, Compression limiters and special RivetNuts
  • Whether for Composites, Vacuum-form, GRP, machined thermosets or light metal alloy constructions, Tappex threaded inserts are the natural 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 applications served by Tappex® for Injection mouldings, GRP, Vacuum-formed & Aluminium Die-Castings with both Brass & Stainless Steel threaded inserts to suit 'all weather' installations
  • 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!
