Custom Other High Temperature Resistant Products

In the process of processing high-temperature resistant special-shaped customized parts, how can laser cutting achieve fast and accurate cutting of materials? Will heat-affected zones or deformations be generated during the cutting process?

Laser cutting technology, with its non-contact, high-precision and high-energy characteristics, has become the preferred method for processing high-temperature resistant special-shaped customized parts. This type of customized parts, due to its unique shape design and application requirements in high-temperature environments, places extremely high demands on cutting accuracy and material properties. As a leader in the field of high-temperature resistant and fireproof new materials, Ningguo Zhongdian Insulation Material Co., Ltd. not only has advanced laser cutting equipment, but also has accumulated rich practical experience and can flexibly respond to the challenges of various complex shapes and high-temperature materials.

During the processing process, the laser cutting machine achieves precise control of the laser beam position through high-precision servo motors and closed-loop control systems. Combined with CAD/CAM software, the company can automatically generate the optimal cutting path based on the three-dimensional model provided by the customer, optimize cutting efficiency, and reduce material waste. In addition, the use of high-power fiber lasers or CO₂ lasers ensures that high-speed and stable cutting efficiency can be maintained even when cutting high-temperature resistant materials with high melting points and high hardness. The application of this technology enables Ningguo Zhongdian Insulation Material Co., Ltd to maintain efficient production capacity while ensuring the accuracy of part size and shape when processing other high temperature resistant products.

Despite the many advantages of laser cutting, attention should still be paid to the heat-affected zone (HAZ) and deformation when processing high-temperature resistant materials. The heat-affected zone refers to the area where the microstructure and performance of the material change due to laser heating, while deformation is the macroscopic shape change caused by the uneven distribution of thermal stress inside the material. Ningguo Zhongdian Insulation Material Co., Ltd effectively controls these problems through the following measures:

Optimize cutting parameters: Based on long-term technical accumulation and practical experience, the company has mastered the best cutting parameters for different high-temperature resistant materials, including laser power, cutting speed, gas pressure, etc., to minimize the heat-affected zone while maintaining the smoothness and precision of the cut surface. This fine parameter adjustment ensures the efficiency of the cutting process and the high quality of the parts.
Auxiliary gas cooling: During the cutting process, the use of inert gas (such as argon) or active gas (such as oxygen) as auxiliary gas can not only promote the oxidation reaction during the cutting process (for some materials), but also effectively take away the heat generated in the cutting area, reduce the scope of the heat-affected zone, and reduce the risk of deformation. The application of this strategy further improves the reliability and stability of laser cutting technology in the processing of high-temperature resistant special-shaped customized parts.

Thermal stress management: Through reasonable cutting sequence and hierarchical design, as well as necessary preheating and post-processing measures, Ningguo Zhongdian Insulation Material Co., Ltd effectively manages the distribution of thermal stress during the cutting process. For example, for large or complex-shaped high-temperature resistant special-shaped customized parts, the use of segmented cutting or alternating cutting strategies can effectively balance thermal stress and avoid overall deformation. This sophisticated thermal stress management ensures the stability of the parts during processing and the reliability of the final product.
