HUAZHUO Automation combines dedicated bumper fixtures, precision punching units, ultrasonic bracket welding, and integrated machine controls in one system. Each solution is configured around the bumper design, bracket locations, and production requirements.
Bumper Locating Fixture
Custom contoured fixtures support and locate the bumper cover for repeatable punching and welding.
Punching Units
Dedicated punch-and-die tooling creates parking sensor, camera, and other specified openings.
Radar Bracket & Sensor Holder Welding
Custom fixtures position compatible radar brackets and parking sensor holders for ultrasonic welding.
Integrated Machine Controls
Centralized controls coordinate bumper clamping, opening punching, bracket positioning, and welding.
Automotive Bumper Punching & Ultrasonic Welding Process
The integrated process combines precision punching of parking sensor and camera openings with ultrasonic welding of plastic mounting brackets, from bumper positioning through final unloading.
Load & Locate Bumper
The bumper cover is loaded into a dedicated fixture and positioned against defined locating datums.
Clamp & Secure Bumper
The fixture secures the bumper cover to maintain consistent alignment during punching and welding.
Punch Sensor & Camera Openings
Dedicated punch-and-die tooling creates parking sensor (PDC), camera, and other specified openings in the bumper cover.
Ultrasonic Bracket Welding
Custom ultrasonic tooling welds compatible radar brackets, parking sensor holders, and other plastic mounts to the inside of the bumper cover.
Release & Unload
The fixture releases the finished bumper cover for unloading at the end of the production cycle.
Punching and ultrasonic welding operations can be coordinated within a single production cycle, depending on the system configuration.
Automotive Bumper Process Control Punching & Ultrasonic Welding
HUAZHUO Automation configures punching and ultrasonic welding parameters for bumper materials, opening geometry, and bracket design. Integrated controls monitor key process conditions.
Punching Parameter Control
Punching pressure and operating speed are set based on bumper material, opening geometry, and tooling requirements.
Multi-Axis Unit Adjustment
Punching and welding units can be adjusted in position and angle to accommodate different opening locations and weld points.
Ultrasonic Welding Parameter Control
Weld time, pressure, and displacement are configured to meet the specific bracket and joint requirements.
Process Monitoring
During operation, the machine control system monitors key process conditions to help maintain consistent punching and welding performance.
