Ultrasonic Riveting 35kHz 1000W Staking Assembly for Automotive Interior Parts
Description:
Ultrasonic welding is widely used in the automotive industry. The sonotrode is correctly dimensioned through the use of finite element analysis (FEA). Applications range from interior components (side door trim, center console) to engine compartment components (cylinder head cover, engine covers), to lighting, filters and acoustic foams. Welders can be operated immediately without heat-up time. Cycle times are short, and energy consumption is low.
Conforming to the spirit of "Service First", ALTRASONIC provides lifetime maintenance to its products for as long as they are used by customers.
Principle:
The basic principle of ultrasonic riveting is to convert
high-frequency electrical energy into high-frequency mechanical
energy acting on thermoplastics in a reciprocating longitudinal
movement, generating frictional heat at the plastic/plastic or
plastic/metal interface, forming local melting, through controlled
melting and shaping plastics. A boss or pin to lock another part.
During ultrasonic riveting, the control flow of molten plastic is
used to lock another part (usually another plastic or metal). The
preformed plastic pin passes through the hole in the part to be
locked, and the high-frequency ultrasonic vibration from the
welding head is transmitted to the upper part of the pin. The pin
is melted due to the frictional heat and fills the cavity volume of
the welding head, resulting in the locking of the spear head.
Components. The plastic pin is gradually melted under continuous
light pressure to form a rivet. The slight pressure of the horn
causes the pin head to form a specific shape (as determined by the
end structure of the horn). After the vibration stops, the plastic
solidifies and a material is consolidated.

1. Uneven asymmetrical geometries can be welded.
2. Delicate component surfaces stay mark-free.
3. Short weld cycles between 100 and 300 milliseconds.
4. Targeted energy input protects sensitive electronic elements.
5. Different types of material can be welded or bonded by embedding.
6. Smaller machine footprint compared to other joining processes.
Application:
1. Lamp plastic riveting
The application of riveting technology in the internal circuit of
the ceiling lamp in the car. The reserved studs on the plastic seat
of the ceiling lamp pass through the pre-punching holes on the
metal sheet, and then the metal plate conductors are riveted by the
hemispherical round caps, and the parallelly placed metal pieces
are separated by the vertical ribs to make them insulated and
shackled. This can effectively prevent the vibration of the metal
piece conductor from falling off, and fundamentally eliminate the
short circuit phenomenon.
2. Door trim riveting
The trim panel skin component that is riveted to the press-formed
wood fiber door frame uses an air core riveting column (tubular hot
pile) for the outer flange riveting process. Due to the large
contact area of the eversion edge and the high connection strength,
the loosening, falling off or tearing caused by long-term vibration
can be effectively avoided, so that the whole component can more
effectively realize the functions of sound absorption, noise
reduction and thermal insulation. Effectively improved the interior
environment. In the narrow part near the edge, the vertical rib
riveting process is adopted to increase the contact area of the
rivet cap, and the phenomenon of tearing and falling off when the
force is applied at the edge is prevented, thereby effectively
overcoming the shortcoming of the poor stretching effect of the
wood fiber board. , and finally combined with plastic parts into a
structure.
