20-Ton Rectangular Transformer Core Order from Indonesia
A major Indonesian power supply manufacturer, specializing in the production of small transformers and control power supplies, whose products are widely used in local home appliances and industrial control sectors, required rectangular transformer cores that met strict specifications, offered high cost-effectiveness, and had stable delivery times.In May 2025, the client contacted us via our website and clearly outlined their procurement requirements: 20 tons of rectangular transformer cores. They required standardized dimensions, neat stacking, and good insulation, suitable for both automated and manual winding. Additionally, they demanded a high cost-performance ratio and a delivery timeframe of within 15 days to ensure the smooth operation of their production line.
After understanding the client’s needs, we promptly compiled a standard parameter sheet for rectangular transformer cores. Based on the client’s specific application, we recommended suitable silicon steel grades and specifications, providing detailed explanations of the product’s advantages, pricing, and delivery lead times. To further reassure the client, we proactively provided samples and test reports, allowing them to directly assess product quality. After evaluating the samples and comparing prices, the client concluded that our products offered excellent value for money and reliable quality, and immediately signed a purchase contract with us.
Standardized Quality Control Ensures High Cost-Effectiveness of Transformer Cores
As a professional manufacturer of transformer cores, we leverage the advantages of large-scale production to effectively reduce manufacturing costs, enabling us to provide customers with high-value rectangular transformer cores. Throughout the production process, we adhere to standardized manufacturing procedures and select premium silicon steel raw materials to ensure consistent material quality and performance compliance.We utilize automated stamping lines for core stamping, precisely controlling dimensions and accuracy to prevent issues such as dimensional deviations and burrs. During the lamination process, we employ precision laminating equipment to ensure the cores are stacked neatly and tightly, thereby enhancing magnetic permeability and reducing losses.
We have established a comprehensive quality control system. All rectangular transformer cores undergo full inspections for appearance, dimensions, and performance before leaving the factory: Appearance inspections focus on checking the core surface for scratches, burrs, deformation, and other issues; dimensional inspections utilize precision instruments to ensure the accuracy of every core’s dimensions; performance inspections focus on testing metrics such as no-load loss and load loss to ensure product performance meets customer requirements.At the same time, we have optimized our packaging process by adopting sturdy, moisture-proof packaging suitable for ocean freight. This ensures that goods remain undamaged during transit while reducing packaging costs, thereby further enhancing the product’s value for money.
