Customer Case Study – Vietnam Automotive Industry

Vietnam Automotive Manufacturer Upgrades with Huazhuo’s Front & Rear Bumper Ultrasonic Punching and Welding Equipment

In 2024, a leading automotive parts manufacturer in Vietnam purchased two customized ultrasonic punching and welding all-in-one machines from Suzhou Huazhuo Automation Equipment Co., Ltd. — one for front bumpers and one for rear bumpers.

This investment was driven by Vietnam’s fast-growing automotive industry and the region’s increasing demand for high-quality, cost-effective plastic bumper assembly solutions.

Market Needs in Vietnam & Southeast Asia

Vietnam and other Southeast Asian countries are becoming key hubs for automotive manufacturing. However, the industry faces unique challenges:

• Hot and humid tropical climate requires equipment with stable heat dissipation and continuous operation capability.

• High-volume production for both domestic and export markets, demanding 24/7 reliable automation equipment.

• Customer requirements from global OEMs for stronger welding strength, defect reduction, and international quality compliance.

• Cost reduction & efficiency improvement, as labor costs in the region continue to rise.

Our Solution: Ultrasonic Punching & Welding All-in-One Equipment

Huazhuo delivered two durable 380V ultrasonic punching and welding automation machines tailored for front and rear bumpers:

• Welding & Punching Integration: Radar hole punching and radar bracket ultrasonic welding completed in one cycle.

• High Stability in Hot Climates: Optimized cooling system ensures stable ultrasonic frequency and power output, suitable for Vietnam’s high-temperature environment.

• Precision & Quality: Ultrasonic punching achieves clean, burr-free holes without damaging the paint surface. Radar brackets are welded firmly without bulging on the bumper’s backside.

• 24-Hour Continuous Production: Designed for uninterrupted operation, with PLC control, real-time monitoring, and multiple protection features (light grid, abnormal alarm, data recording).

• Durability & Reliability: Built with stainless steel base plates, forged copper molds, and high-temperature resistant components to ensure long life and consistent performance.

After installation and stable mass production, the Vietnamese customer reported:

• High output and high utilization, supporting large-volume production.

• Improved welding strength and consistency, fully meeting international automotive standards.

• Substantial cost savings from shorter welding cycles, reduced labor, and lower defect/rework rates.

• Estimated payback period of just one year, thanks to efficiency gains and material savings.

• Reliable performance under tropical conditions, ensuring continuous operation without overheating.
