A professional Canadian Tier 2 automotive supplier, focusing on the production and processing of automotive plastic parts. The company mainly provides interior and exterior plastic decorations, plastic wheel arch shields and plastic wiring harness accessories for Ford and GM aftermarket markets, undertaking multi-variety, mixed-batch production orders all year round.

For a long time, the factory adopted glue bonding and hot riveting to assemble plastic components. The long curing cycle of adhesive seriously restricted production capacity and order delivery efficiency. Meanwhile, traditional thermal processing was prone to scalding and deforming thin decorative plastics, resulting in high cosmetic defect rates. In addition, large fixed ultrasonic equipment was inflexible, unable to adapt to narrow hidden welding positions and diversified small-batch production, leading to unstable product quality and high rework costs.

To solve the above problems, the customer introduced our plastic-dedicated 28kHz handheld ultrasonic welder. We configured multiple interchangeable professional plastic welding and riveting molds according to the customer’s product characteristics, and precisely adjusted welding amplitude, pressure and time parameters for automotive-grade PP, ABS and TPO plastics, matching various plastic assembly and reinforcement processes on site.

After equipment upgrading, the traditional glue curing process was completely eliminated, and the overall assembly efficiency of plastic parts increased by 42%. The cosmetic surface defect rate of finished automotive plastics dropped from 10.7% to 1.1%. One portable device replaces multiple sets of traditional processing equipment, simplifying workshop stations and reducing equipment investment costs. All plastic welded joints have passed strict OEM long-term vibration and high and low temperature cycle tests with stable performance. Satisfied with the trial production effect, the customer finally placed a bulk order to complete the overall production upgrade of the plastic parts workshop.
