Thread creation

AMTEC®

Secure and stress-free anchoring of thread inserts. With AMTEC® high-strength thread inserts for plastic parts.

Embedding in plastic

AMTEC® stands for “After Moulding TEChnology” and refers to the installation of thread inserts in plastic components after moulding.

Today the world of lightweight construction can no longer be imagined without plastics, and they are conquering ever more sectors. Their great flexibility in terms of processing and component design leads to an increasing replacement of metallic materials by plastics. Due to their outstanding mechanical properties, low weight and attractive manufacturing costs, plastics are a fundamental part of industry today. AMTEC® thread inserts make it possible to achieve the advantageous synergy effects resulting from high-strength metals in combination with plastics.


Method / principle

AMTEC® thread inserts have been specifically designed for after moulding installation. The result: a wear-free, high-strength thread in your high-quality plastic components.

Applications

AMTEC® thread inserts are suitable for installation in moulded parts made of thermoset / thermoplastic materials and FCP or CFRP. They are used in an enormous range of sectors, for example in air bags, automotive interiors and air-conditioning systems, in addition to office furniture.

Benefits
  • Shorter injection cycles
  • No risk of damaging the injection mould
  • No stress cracks
  • Secure, stress-free anchoring
  • Reduction in relaxation effects
  • Multi-release joining points

Product benefits

There are many good reasons for using our products.

Strength and options.
Point by point.

Shorter injection cycles

No time wasting. Injection moulding takes place automatically and without inserting metal parts.

No damage to the injection mould

Reliable manufacturing. Without metal parts that could fall out.

Secure, low-stress anchoring

High pull-out and torsion values. Based on the use of heat, a tight fit with low stress during cooling results.

Reduction in manufacturing costs

Top quality despite cost savings. Thread inserts from AMTEC® have been specifically designed for after moulding installation. The result: a wear-free, high-strength thread in your high-quality plastic components.

Detailed description

 

AMTEC® installation procedure – Heat element welding (HEW)

Heat element welding is a tried and tested joining technique to embed metal thread inserts into thermoplastic mouldings. During the single-phase process, contact heat is transferred to the joining zone of the plastic via the metal insert. Joining takes place on fusion of the plastic at the contact surface. During this process, the plasticised mass is forced into specific recessed areas and undercuts to produce a form-closed joint.

AMTEC® installation procedure – Electromagnetic resistance welding (ERW)

ERW (electromagnetic resistance welding) is a technique developed by KVT Bielefeld for the joining of metal and thermoplastics. An electromagnetic AC field heats the thread insert without contact and the contact surface of the plastic component is plasticised. During the simultaneous joining process, the melted material is forced into recessed areas and undercuts.
Metal elements of any size are heated up extremely quickly (approx. 2 – 6 s). After switching off the power supply, accelerated cooling of the melt takes place, allowing an installation accuracy of up to 0.05 mm.

AMTEC® installation procedure – Ultrasonic welding (USW)

USW is a process that was originally developed for joining thermoplastic parts. Within a very short time, the plastic material is plasticised by boundary-layer friction and vibration absorption of the parts to be joined. This is followed by the joining process. The necessary energy is generated as alternating voltage in the ultrasonic generator, converted into mechanical vibration (20 – 40 kHz) and then introduced with a sonotrode. With the embedding of thread inserts (metallic M 2 – M 6) in the thermoplastic material, the melted material is forced into recessed areas and undercuts.
