Under extreme working temperature, fast feeding and stripping operation and excessive mold gap conditions, glass mold punches are prone to material loss on the punch surface, forming pits and pits, which eventually lead to the punch being unable to be used normally. At present, many mold manufacturers on the market are highly dependent on imported punches to meet production needs, but with the vigorous development of the domestic market and the sharp increase in demand, the supply capacity of foreign punches is gradually stretched. Therefore, it is imperative to explore and apply new processes to replace traditional plasma or spraying technology.

Based on the fine structure of glass mold punches and the customized needs of laser cladding, our company has innovatively launched a special machine for laser cladding of glass mold punches with its deep accumulation in this field. This special machine integrates high-end configuration and cutting-edge technology, is equipped with self-developed intelligent software, and is equipped with core components such as dedicated laser heads, nozzles, and powder feeders to ensure accuracy and efficiency. The five-axis automated CNC platform flexibly responds to punches of various specifications, and the supporting processes are accurately matched to achieve stable and fully automated operations under working conditions, demonstrating our company’s technical strength and innovative achievements.

Advantages of laser cladding process

Laser cladding process can significantly improve the hardness, strength, wear resistance and corrosion resistance of the punch, ensuring that the punch can still show excellent performance in harsh working environments. By optimizing the production process and technological innovation, the high performance requirements of the punch can be achieved at a lower cost, thereby effectively replacing imported punches, not only alleviating supply chain pressure, but also further enhancing the market competitiveness of the domestic mold manufacturing industry.

1. Excellent wear and corrosion resistance: With its precise control ability, laser cladding technology accurately constructs a layer of ultra-hard ceramic coating and a highly dense corrosion-resistant barrier on the surface of the punch, greatly enhancing the wear and corrosion resistance of the punch under extreme working conditions, ensuring continuous and efficient operation, and significantly extending the service life of the punch.
2. Precise repair and performance optimization: This technology has completely revolutionized the field of punch surface strengthening and repair, and achieved fine repair of surface defects; at the same time, surface strengthening or modification can be performed directly on the punch surface, greatly shortening the manufacturing cycle, reducing costs, and improving overall production efficiency.
3. Excellent material bonding performance: The laser cladding layer forms a strong metallurgical bond with the substrate, and the dilution rate of the cladding layer is as low as 5%-8%, which effectively prevents the common peeling problem in traditional coating processes and ensures the long-term stability and reliability of the cladding layer.
4. Wide material adaptability: The laser cladding process is compatible with a variety of materials, and the most suitable cladding material can be selected according to different production needs and punch performance requirements.
5. Low heat input and small deformation: The heat input of laser cladding is relatively low, and the heat-affected zone is small, which is conducive to maintaining the accuracy and performance of the mold punch.
6. High production efficiency: Laser cladding has the characteristics of high solidification speed, which makes the cladding process faster and more efficient, and does not require additional front and back heat treatment processes.

Equipment advantages

1. Efficient processing and high-precision repair: high-energy laser beam focusing is used to accurately control the thickness and shape of the cladding layer, and the metal powder is quickly melted to form a metallurgical bond with the substrate, ensuring that the precision of the repaired mold punch meets the design requirements.
2. Excellent coating performance: alloy coatings with excellent wear resistance, corrosion resistance, high-temperature oxidation resistance and other properties are clad on the surface of the mold punch, which significantly improves the service life of the mold punch.
3. Wide applicability: It is suitable for surface strengthening and repair of punches of various materials, including common glass mold materials such as cast iron and copper alloy; at the same time, it is also suitable for repairing punches of different shapes and sizes.
4. Intelligent and visual operation: equipped with advanced automatic control system and intelligent operation interface, it can realize automatic operation and remote monitoring of the equipment; at the same time, it also has the function of visualizing the repair process. By real-time display of key parameters such as temperature, speed, thickness, etc. during the cladding process, the operator can adjust the process parameters in time to ensure the best repair effect.
5. Customized service: We can provide customized laser cladding solutions according to the specific needs of customers, including customized services in equipment configuration, process parameter adjustment, cladding material selection, etc., to ensure that customers obtain the best repair effect and economic benefits.
