Household & Consumer Goods超声波焊接
No marks on show surfaces, fast assembly - one machine for welding, insertion and staking
Appliances and household goods are high-volume consumer products: thin margins, cycle times counted in seconds, and visible surfaces that tolerate no witness marks, blush or flash. Ultrasonic welding takes seconds, adds no adhesive or screws, and keeps any mark out of sight through contoured horns and joints that hide the flash. The same machine does two more jobs with a change of horn - melting metal inserts into plastic (insertion), and forming plastic bosses into rivet heads to capture metal parts (staking) - which in appliance assembly is used even more than welding itself. Sealed parts such as water tanks, pump bodies and steam components rely on shear joints for a hermetic weld all round.
Typical Welded Parts
Common ultrasonic welding and cutting stations in this industry
Speakers and audio assemblies
A continuous ring weld between basket and grille that must not change cone compliance or the sound of the driver
Thermostats and wall controls
The weld around the panel and housing must sit flat, with no gap or step once it is mounted on the wall
Control panels and membrane switches
Membrane bonded to panel without a raised weld spot changing the feel of the key - low amplitude, short time
Vacuum hoses and couplings
A ring weld between corrugated hose and rigid fitting that must not crack or leak under repeated flexing
Vacuum nozzles and handles
Large thin-walled parts with long welds, needing a fixture that supports the whole perimeter against cracking
Threaded inserts and bushings
Metal inserts melted into plastic, where pull-out force and torque are set by the pilot hole dimensions
Swaged rotating assemblies
A metal hub swaged onto a plastic disc that must still turn freely afterwards, with no free particles generated
Dampers and shock absorbers
The ABS body is welded to its base, filled with oil, then capped - both welds must be oil- and air-tight
Sewing machine threader heads
A stainless steel stamping staked to a plastic body, where the rivet head must form fully and leave no burr
Toy parts and housing closures
Three-dimensional ABS surfaces joined; watertightness is not required, but water that gets in must drain out
Livestock ear tags with chips
A memory chip sealed inside a two-part PA housing where the weld must not spatter; PA suits years outdoors
Coin slots and vending components
Three brass threaded studs inserted into a PC/ABS panel in one shot, with consistent pull-out force
Why LINQISONIC
From joint design to line integration, we solve one thing: welds that hold and stay consistent
One machine, three jobs
A change of horn switches between welding plastic to plastic, inserting metal parts into plastic, and staking plastic bosses over metal. In appliance assembly the last two see more use than welding itself, and none of it needs another machine.
No marks on show surfaces
Visible faces tolerate no witness marks, blush or flash. Three things solve it together: a contoured horn that follows the surface, near-field welding to shorten the sound path, and a tongue-and-groove joint that traps the flash. This is what separates consumer parts from industrial ones.
Cycle times in seconds
A weld typically takes one to three seconds with no curing wait, so the part moves straight to the next station. On high-volume consumer goods the saving is in cycle time and work-in-progress, not just in materials.
Hermetic seals all round
Water tanks, pump bodies and steam components that must pass a leak test use a shear joint to form a continuous fused band down the wall, controlled in energy mode for part-to-part consistency.
No adhesive, no screws
No curing wait, no solvent smell, and no screws or clips taking up space. The part stays single-material, which keeps recycling and disassembly simple and the assembly station clean.
Weld trials before commitment
Send us the part or the drawing. We weld samples first and run pull and leak tests, then fix the joint design, horn, fixture and machine configuration.
