You ask, we answer
Find answers to common questions about our ultrasonic metal welding equipment, sample testing process, custom lead times, and global technical support.
You send us your material specifications, drawings, or physical samples. Our engineering team performs trial welding in our Wuxi lab and provides a detailed test report—including tensile test results and cross-section analysis—before you place an order.
Standard equipment is delivered within 14 to 45 business days. For non-standard or customized equipment, the lead time is determined based on project complexity and mutual agreement between both parties.
We provide a standard 12-month warranty covering major components, along with lifelong technical guidance, remote video troubleshooting, and fast international shipment of replacement parts.
Yes. Our ultrasonic welding modules and digital generators are designed for easy integration into standard automated assembly lines, supporting communication with PLC and MES systems.
