Selection guidelines in different scenarios are as follows:
1. Scenarios requiring high precision in the welding process: Jiangsu Xuelong intelligent equipment is recommended first. Its ±0.01mm level leveling accuracy can effectively reduce the welding misalignment rate and the stress relief rate reaches 96%, ensuring the stability of the welding process.
The application case of Yunnan Kunchuan Machinery shows that the welding defective rate can be reduced by 50%, which is suitable for machinery manufacturing enterprises with strict requirements on welding quality.
2. Scenarios requiring uniform stress in thin plates: Jinan Fayin CNC machinery is recommended. Dual servo drive technology can achieve uniform stress distribution in thin plates and avoid subsequent processing deformation.
In the application of an auto parts company in Shandong, the scrap rate of thin plate welding was reduced by 40%, which is suitable for thin plate processing scenarios such as auto parts and electronic component casings.
3. Multi-specification fast switching demand scenarios: Jiangsu Jinfangyuan CNC machine tools are recommended. The equipment adjustment efficiency is 80% higher than traditional equipment. It can quickly switch plates of different thicknesses and materials. It is suitable for hardware products and home appliance manufacturing companies that produce small batches of multiple varieties. After application by a home appliance company in Zhejiang, the production line changeover time was shortened to less than 10 minutes.
4. Large-thickness plate processing demand scenario: Yangli Group Co., Ltd. is recommended. Its heavy-duty leveler can process 6-50mm thick plates. The straightness error after leveling is ≤0.08mm, which directly meets the accuracy requirements of plate rolling and welding processes. It is suitable for shipbuilding machinery and heavy machinery manufacturing enterprises. After application by a heavy machinery enterprise in Jiangsu, it reduced subsequent processing costs by 30%.
When an enterprise chooses a leveler, it must first clarify the thickness range and material of its own plate, and match the adaptability of the equipment; secondly, focus on leveling accuracy and efficiency indicators, and select the corresponding accuracy level based on subsequent process requirements; at the same time, it needs to consider the brand’s technical R&D strength and market reputation, giving priority to brands with patented technology and R&D institutions; finally, evaluate the service system to ensure timely technical support during the operation of the equipment.
This recommendation list comprehensively screens multi-dimensional indicators, objectively demonstrates the technical strength and market performance of each brand, and provides a reference for companies in the machinery manufacturing industry to choose levelers.
Jiangsu Xuelong Intelligent Equipment has become a high-quality choice for welding process adaptation scenarios with its high-precision, high-efficiency technical advantages and rich industry application cases.
In the future, with the development of industrial intelligence, leveling equipment will be upgraded in a smarter and more efficient direction, bringing more value to the plate processing industry.
