Recently, the desktop AC precision spot welding machine delivered by PDKJ has been successfully installed at the workshop of an electronics and electrical appliance customer, specifically for spot welding of power strip copper terminals. The equipment operates stably with outstanding welding quality, effectively helping the Ningbo-based enterprise optimize its production process, reduce manufacturing costs, and create immediate production value upon installation.
I. Project Background
Customer Overview
The customer in this cooperation is an enterprise specializing in the R&D and manufacturing of core electronic and electrical components. Its main products include various safety sockets, industrial power strips, and matching copper terminals and components. These products are widely used in household appliances, office equipment, industrial control systems, and other fields, where strict standards are required for conductivity, safety, and production consistency of internal copper connections.
Project Origin
With the growth in market orders and product upgrades, the customer’s original welding equipment could no longer meet the precision welding requirements of power strip copper terminals. The customer urgently needed a dedicated precision spot welding machine to solve production challenges, improve product quality, and enhance production efficiency, which became the key reason for this cooperation with PDKJ.
II. Customer Pain Points & Core Requirements
As an essential consumer electrical product, power strips rely on copper terminals as their core conductive components. Due to copper’s high thermal conductivity and the small size of the workpieces, welding such terminals requires extremely high equipment precision and stable current output.
Before upgrading the equipment, the customer was still using traditional outdated welding machines for copper terminal processing. During mass production, several process shortcomings became apparent, mainly including the following three problems:
1. Poor Welding Stability
The old equipment had unstable current output, causing weak welds and false welding on copper terminals, resulting in inconsistent product qualification rates.
2. Rough Weld Appearance
Uncontrolled heat generation during welding easily caused blackening of the workpieces and obvious indentation marks, affecting product appearance and assembly quality.
3. Complicated Changeover & Adjustment
When switching production between different terminal specifications, the setup and adjustment procedures were complicated and time-consuming.
Customer Requirements
Firm welds with stable conductivity
High consistency in batch welding production
Simple and convenient equipment adjustment
III. Core Advantages of the PDKJ Welding Machine
In response to the customer’s welding pain points for power strip copper terminals, the PDKJ technical team conducted detailed communication with the customer and performed welding sample tests using the original copper terminal workpieces. Ultimately, the DN-25T Desktop AC Precision Spot Welding Machine was selected.
Focused on precision welding, stable efficiency, and strong adaptability, the machine offers the following practical production advantages:
1、Precision Current Control Eliminates Welding Defects
Equipped with a new-generation microcomputer controller, the machine provides highly precise current control and allows accurate adjustment of welding current, welding time, and other parameters. It perfectly meets the welding requirements of copper terminals, effectively solving the challenges of copper’s rapid heat conduction and easy oxidation. The weld nugget is uniform, eliminating weak welds and false welding while ensuring terminal conductivity and safety.
2、Rigid Machine Body + Direct Pressure Mechanism for Maximum Consistency
The machine adopts a high-strength rigid structure combined with a direct pressure mechanism. The guide components feature excellent follow-up performance and stable pressure application without slipping, effectively preventing electrode displacement. This ensures highly consistent weld strength and appearance during batch production while significantly reducing rework rates.
3、Compact Desktop Design Suitable for Workshop Layouts
Its compact desktop structure occupies minimal space, making it especially suitable for precision workpiece welding and assembly line production. Equipped with a high-performance pneumatic system, the pressure speed can be adjusted freely. The machine is easy to operate and lowers the skill threshold for workers.
The machine is equipped with a circulating water-cooling system that provides excellent heat dissipation, extends electrode service life, and reduces consumable replacement costs. With low overall energy consumption, stable operation, and low failure rates, the equipment minimizes downtime and maintenance, helping customers achieve cost reduction and efficiency improvement.
IV. Delivery Results: Stable Production Creates Value
After the equipment selection was finalized, PDKJ provided one-stop services including equipment delivery, installation, commissioning, and operator training, enabling the machine to be quickly integrated into the customer’s production line.
Currently, the equipment is operating stably for long-term terminal spot welding production, with excellent customer feedback:
Strong welds without blackening and stable electrical conductivity, significantly improving batch production qualification rates
Simple product changeover and adjustment, compatible with multi-specification product manufacturing
Reduced electrode consumable loss, effectively lowering production costs
Stable and cost-effective production performance highly recognized by the customer
