PDKJ Special Machine Delivery Case

I. Customer and Project Background

• Stringent Appearance Quality Requirements: Smart IoT devices are mostly aimed at end consumers, who have extremely high demands for the aesthetic appeal and refinement of the product appearance. After welding, the galvanized door panel must not have obvious weld marks, deformations, or defects, as these would affect the overall image of the product and reduce its market competitiveness.
• Need for Improved Welding Efficiency: With the continuous growth of market demand and the increasing number of customer orders, the existing welding equipment and processes are no longer able to meet the growing production needs. There is an urgent need for an efficient and stable welding solution to shorten production cycles and increase production capacity.
• Inconvenience in Welding Large-Sized Door Panels: With the diversification of smart IoT devices, some of the galvanized door panels have increased in size. The throat depth of ordinary welding machines is insufficient to meet the welding needs of these large-sized panels, making it difficult to weld in some positions and seriously affecting production efficiency and product integrity.

II. Highlights of the Customized Welding Machine

1. Precision Welding for Quality Assurance
   Addressing the customer’s stringent requirements for welding accuracy and appearance of galvanized door panels, PDKJ’s vertical medium-frequency extended-arm projection welder precisely controls the current intensity and duration during the welding process. This ensures even heat distribution, effectively avoiding issues such as weld marks, burn-through, and deformation caused by unstable current. The resulting galvanized door panels have a smooth surface, ensuring good sealing and enhancing the overall aesthetic quality, meeting the high standards for the appearance of smart IoT devices.
2. High-Efficiency Operation to Boost Productivity
   To satisfy the growing production demands of the customer, the welder is equipped with a rapid-response welding system. With an inverter frequency of up to 1000Hz, it can quickly complete the welding action, significantly reducing the welding time for each product. Additionally, the equipment’s duty cycle has been optimized for stable operation over extended periods, minimizing downtime and effectively increasing overall production efficiency. This enables the customer to easily handle large orders and shorten delivery times.
3. Extended Throat Depth for Large-Sized Workpieces
   Considering the customer’s need to weld large-sized galvanized door panels, PDKJ extended the throat depth of the DTB-80 welder to 1000mm. This unique design allows the welder to reach various positions on the door panel for welding, including edges, corners, and deeper internal areas. Combined with the flexible adjustable electrode arm and welding head, it can adapt to different welding positions and angles, ensuring optimal welding results at every point. This design completely solves the problem of welding large-sized workpieces, providing strong support for the diverse design and production of customer products.

III. Project Outcomes

The successful delivery and application of the “Vertical Medium-Frequency Extended-Arm Projection Welder” have yielded significant results for the Hangzhou smart IoT customer in the welding of galvanized door panels for electrical control cabinets. In terms of product quality, the defect rate caused by welding appearance flaws has been virtually eliminated, and welding strength has been greatly enhanced. This not only reduces the rate of non-conforming products but also increases the reliability of the products in subsequent use, leading to a noticeable decrease in after-sales feedback issues. In terms of production efficiency, the customer’s production capacity has increased by 30%, allowing them to better seize market opportunities and take on more orders, achieving a double harvest in economic benefits and market competitiveness.

PDKJ is always committed to providing high-quality welding solutions for customers. In this cooperation, the medium-frequency inverter DC projection welder with an extended throat depth not only meets the customer’s needs for efficient and precise welding but also ensures perfect adaptation to the customer’s production process through customized services.
