Embedding in plastic

AMTEC® stands for "After Moulding TEChnology". If refers to the after-moulding insertion of thread inserts into plastic components.
Get an overview of our insertion solutions.

Characteristics

After-moulding insertion into plastic parts bears many benefits:

AMTEC® After Moulding Technology
  • Shorter injection cycles and thus lower manufacturing costs for plastic components
  • Safe, stress-free anchorage
  • High pull-out and torsion values
  • Any repeated screwing as opposed to self-forming screws

Installation procedures

Hot plate welding

Hot plate welding is an approved joining process for inserting metal thread inserts into thermoplastic moulded parts. In the single-phase process, contact heat is transferred via the metal insert to the joining zone of the plastic. During fusion of the plastic in the area of the contact surface, joining is carried out. Upon this process, the plasticized mass is displaced into defined recesses and interlocks. That is how a form-closed joint is built.

Thermal-inductive insertion (ERW)

Thermal installation by electromagnetic resistance welding (ERW) of metal thread inserts

ERW (electromagnetic resistance welding) is a joining process developed by KVT Bielefeld GmbH (Germany) for joints of metal and thermoplastic components. An electromagnetic field heats the thread insert without contact and the contact surface of the plastic component is plasticized. In the simultaneous joining process, the fused material is displaced into recesses and interlocks. Heating of metal elements of any size is executed within a very short time (approx. 2 - 6 sec.). After switching off energy, accelerated cooling of the melt takes place allowing an installation accuracy of up to 0.05 mm.

Ultrasonic installation (USW)

Ultrasonic installation of metal thread inserts or K' in 'K plastic thread inserts

Ultrasonic installation (USW - ultrasonic welding) is a process which had originally been developed for joining thermoplastic components. Within a very short time, the plastic material is plasticized by boundary-layer friction and vibration absorption of the parts to be joined. After that, joining is executed. The energy required is generated as alternating voltage in the ultrasonic generator, converted into mechanical vibration (20 - 40 kHz) and then introduced with a sonotrode. Upon the installation of thread inserts (metallic M 2 - M 6) into thermoplastic components, the fused material is displaced into recesses and interlocks.
