PDKJ shares a typical cooperation case in the Foshan household hardware industry. For a leading Foshan household hardware enterprise troubled by welding accuracy and mass-production bottlenecks in slide-rail products, PDKJ precisely supplied vertical medium-frequency inverter DC projection welding machines, paired with custom jigs tailored to slide-rail workpieces. The resulting “equipment + jig” integrated welding solution saw more than ten machines successfully delivered, efficiently resolving the customer’s production challenges.
Thanks to the equipment’s stable performance, highly adaptable custom jigs and full-cycle professional service, the customer has continued to place follow-up orders, successively purchasing additional units of the same series and other PDKJ welders. This long-term partnership testifies to the practical value of PDKJ’s solution and underscores its solid strength in the welding segment of this niche industry.
I. Project Background
In the Foshan household-hardware belt, slides are small yet mission-critical components. Their smoothness, stability and durability dictate the “hand-feel” of every piece of furniture. To make a slide both silky and long-lasting, weld quality is decisive.
The customer in this project has spent more than ten years specializing in household hardware and is now a flagship exporter with sizable capacity. Its portfolio covers slides, hinges and furniture accessories, supported by fully fledged stamping, assembly and surface-treatment lines. As orders surged, the company’s core product—the slide—had to meet two welding requirements imposed by high-end cabinets, wardrobes and car seats:
-
Absolute “zero cold-weld” to guarantee lifelong smoothness and load-bearing strength (≥ 100 000 push-pull cycles without loosening);
-
Compatibility with a daily output of several thousand sets, eliminating the throughput bottleneck caused by legacy equipment.
Consequently, the customer urgently needed a new welding-equipment supplier capable of matching both its capacity expansion and its premium-quality standards.
II. Customer’s Welding Requirements
The customer’s legacy welders already suffered from low speed and poor accuracy; with orders exploding and lead-times shrinking, those machines could no longer deliver the high throughput, repeatable quality or scale-economy the business now needed:
-
Spot consistency – thin slide rails distort easily and cold-weld;
-
Positional precision – multi-point welds demand high repeatability;
-
Capacity upgrade – old equipment could not keep pace with batch orders;
-
Cosmetic finish – minimal marking and spatter.
After comparing suppliers and confirming PDKJ’s technical depth, reliability and practical track record, the customer approached PDKJ for a dedicated welding solution.
III. PDKJ Welder Highlights & Advantages
To match the customer’s slide-rail welding needs, PDKJ engineers walked the shop-floor, studied the cold-rolled and stainless sheets used for the rails, and built an “equipment + jig” package around the DTB-160 vertical medium-frequency inverter DC projection welder.
1. More stable spots
The vertical medium-frequency inverter DC spot welding machine uses medium-frequency inverter DC technology, resulting in cleaner welding current, more precise output, and less spatter. For thin plate structures like slide rails, it effectively avoids incomplete welds and overheating, resulting in fuller weld shapes and smoother appearances.
2. Precision that lasts
The vertical C-frame keeps ram deflection negligible; force stays constant swing-shift after swing-shift. Customer quote: “Spots look identical no matter which operator or shift.”
3. Intelligent system makes operation easier
The digital welding parameters are adjustable and storable, allowing workers to simply select the recipe for production. The system can also record the welding status and automatically alarm in case of abnormalities, greatly reducing human error.
4. Rugged, multi-material reliability
Considering the diverse range of metal materials used by our clients, including stainless steel, carbon steel, and cold-rolled steel, the equipment employs high-temperature resistant and wear-resistant chromium-zirconium-copper welding components. This allows for rapid heat dissipation during welding, reducing workpiece deformation and ensuring stable performance across all metal components after welding. Furthermore, the equipment's overall structure is durable, resulting in a low failure rate over long-term use and guaranteeing continuous production.
5. One machine, every rail style
The equipment boasts a wide welding range, not only efficiently completing slide rail welding but also perfectly adapting to the welding needs of various types and specifications of slide rail products—such as three-section ball bearing slide rails, two-section concealed rebound slide rails with pins, saddle-type drawer slide rails, and damped synchronous slide rails. A single machine can cover the welding production of multiple specifications and types of slide rails, improving the welding machine's process adaptability and single-unit capacity output.

IV. Win-Win Cooperation: Make Metal Welding Easy for the World
In this project, PDKJ delivered more than a dozen vertical medium-frequency inverter DC spot welding machines to the customer and assisted in completing the entire process of "production line planning assistance, equipment installation and placement, welding parameter optimization, and technical training guidance" in a short period of time.
One month after the equipment was put into mass production, customer feedback showed significant results: the consistency of weld points was greatly improved, the welds were uniform and full without any problems of incomplete or missing welds, the yield rate of slide rails was significantly improved, and production losses and rework costs were significantly reduced; the intelligent control system of the equipment made manual operation easier and more efficient, and a single person could manage multiple machines, while the equipment had excellent operational stability, almost zero failures, low maintenance costs, and no downtime or production interruption.
Based on the positive results of the collaboration, the customer initiated a follow-up order shortly after the initial equipment went into production, purchasing multiple spot projection welding machines and other PDKJ series welding equipment to expand new production lines and replace aging equipment. The customer representative stated, "PDKJ's welding machines not only solved our core production problems, but their subsequent technical support was also very timely. We feel very confident choosing to cooperate long-term!"
