Hebei Jinlongyu Import And Export Trade Co., Ltd. proudly presents our latest Automatic Curved Top Fence Welding Machine, engineered to handle wire diameters from 4 mm to 12 mm with precision and speed. This machine is designed for manufacturers who demand high-quality fence panels with consistent curved tops, essential for security and decorative fencing in residential, commercial, and agricultural applications. Built with a robust safety guard system, it ensures operator protection while delivering uninterrupted production. Our factory, located in Hengshui, Hebei, China, combines years of welding technology expertise with rigorous quality control to offer you a reliable, cost-effective solution for your fencing production line.
This fully automatic welding machine integrates advanced PLC control, servo-driven feeding mechanisms, and a pneumatically pressurized welding head to achieve up to 60 panels per hour (depending on size and wire gauge). The curved top forming unit is seamlessly synchronized with the welding process, eliminating the need for secondary bending operations. Whether you are producing standard panels or custom designs, our machine provides the flexibility and consistency needed to meet diverse market demands. Backed by our experienced technical team, we offer installation, training, and after-sales support to ensure you get the maximum return on your investment.

Frequently Asked Questions
Q1: What types of wire can this machine weld?
It can weld solid steel wire, pre-galvanized wire, and stainless steel wire (304/316) within the 4-12mm diameter range. For special alloys, please consult our technical team.
Q2: How long does it take to change over from one panel size to another?
The adjustable tooling allows size changes in approximately 10–15 minutes. Width and height adjustments are motorized and controlled via the touch screen.
Q3: Does the safety guard comply with international standards?
Yes, the full enclosure with interlocked doors and dual emergency stops is designed according to common international machinery safety guidelines (e.g., EN 953, ANSI B11). Specific certifications can be provided upon request.
Q4: What is the power consumption per panel?
Average power consumption is about 1.3–1.8 kWh per panel (for standard 2400×1200mm panel with 6mm wire). Actual consumption varies with wire diameter and welding parameters.
Q5: Do you provide installation and training at my factory?
Yes, we can send a technical engineer for on-site installation and training. Alternatively, we offer online video guidance for experienced technicians. Travel and accommodation costs are quoted separately.
Q6: What is the typical lead time for this machine?
Standard lead time is 30–45 days after receipt of deposit, depending on current production schedule. Customized machines may require 50–60 days.
Q7: Can I produce curved top panels with different radii?
Yes, the curved forming module is adjustable to produce radii from 50 mm to 500 mm. Custom dies can be made for very specific curves.
Q8: What is the warranty period?
We offer a 12-month warranty from the date of shipment against manufacturing defects. Optional extended warranty packages are available.
