Mexican Client Requests Quote for 40-Ton Rectangular Transformer Core
A major Mexican industrial equipment manufacturer, long dedicated to the R&D, production, and sales of industrial power supplies and power distribution equipment, has products widely used in local industrial production and infrastructure construction. The company maintains a large and stable demand for rectangular transformer cores.In January 2025, the client contacted us through our official website with a specific procurement request: 40 tons of standard-specification rectangular transformer cores. The material must be high-quality silicon steel sheets to ensure material consistency and compliance with no-load and load loss standards. Additionally, the client required delivery within 20 days to maintain 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 commonly used specifications, we provided detailed explanations of key information such as material, dimensions, loss values, and magnetic flux density, and proactively offered samples for the client’s testing. To give the client a more intuitive understanding of our product quality, we also sent relevant materials such as production process videos and quality inspection reports, allowing the client to fully grasp our production capabilities and quality control standards.After receiving the samples and documentation, the client conducted professional testing and confirmed that the products met their usage standards, promptly signing a purchase contract with us.
Standardized Production and Quality Inspection Ensure the Quality of Rectangular Transformer Cores
As a professional manufacturer of transformer cores, JINMA Transformer Core operates a mature production line for rectangular transformer cores, enabling large-scale, standardized production and effectively ensuring batch consistency.During production, we utilize automated stamping lines for core stamping, precisely controlling dimensions and accuracy to prevent issues such as dimensional deviations and burrs. In the laminating stage, we employ precision laminating equipment to ensure the core is stacked neatly and compactly, thereby enhancing magnetic permeability and reducing losses.
To ensure product quality meets standards, we have established a comprehensive quality inspection system. All rectangular transformer cores undergo thorough testing before shipment: loss testing ensures that no-load and load losses meet customer requirements; dimensional inspection uses precision instruments to ensure the outer diameter, inner diameter, and stack thickness of each core are accurate; insulation testing ensures good insulation performance to prevent safety hazards such as electrical leakage during use;A full visual inspection focuses on checking the core surface for scratches, burrs, deformation, and other issues, ensuring the product’s appearance is clean and intact. Each batch of products comes with a complete inspection report, giving customers greater peace of mind during procurement.
Transformer Cores Approved by Mexican Purchasing Client
In accordance with the contract, we completed the production, inspection, and packaging of 40 tons of rectangular transformer cores within 20 days. As these were export goods, we employed moisture-proof and shock-resistant packaging compliant with international maritime shipping standards, effectively preventing moisture damage and breakage during long-distance transport. Additionally, we assigned a dedicated international trade team to handle customs clearance, logistics, and related matters, tracking the shipment’s progress throughout the process to ensure the goods arrived safely at the port in Mexico.
Upon receiving the shipment, the client immediately unpacked and inspected the goods. After comprehensive testing and on-site assembly trials, they provided the following feedback: “The product quality exceeded our expectations; consistency was excellent, assembly efficiency was high, and operation was stable with no abnormalities—fully meeting our production requirements.” The client expressed high recognition of our production capabilities, quality control, and international trade service processes, and placed a follow-up batch order on the spot.With our well-established export procedures and extensive experience in overseas delivery, we support various trade terms such as FOB and CIF, and provide customs clearance, logistics, and clearance support to help overseas clients efficiently procure rectangular transformer cores. Moving forward, we will continue to optimize our products and services to provide global customers with core solutions that offer even better value for money.
