Laser technology will accelerate the optimization of the structure of the precision mold industry.

2018-06-28

The development and growth of the mold industry is in line with economic development. Currently, the production technology of China's mold industry is relatively unbalanced at various levels, and many high-end product production technologies are constrained by foreign technologies. There is a need for strong support to develop and achieve synchronization with the international market, and these deficiencies need to be compensated by laser technology.Laser technologyOnly with the advantages of laser technology can China's mold production technology quickly achieve parity with international standards.
Laser surface hardening technology stands out in mold manufacturing.
Laser surface treatment technology can enable low-grade materials to achieve high-performance surface modification, reaching the best combination of low-cost part manufacturing and high-performance working surfaces, with considerable economic and social benefits.
The energy of the laser beam can be continuously adjusted, and there is no inertia. Combined with a numerical control system, it can perform localized hardening treatment on complex-shaped parts and other parts that are difficult to handle with conventional methods, and different laser hardening treatments can be applied to different parts of the components.
Because of the above characteristics of laser surface treatment, it is particularly suitable for surface reinforcement treatment of certain parts and their local positions that are difficult to achieve with conventional hardening treatment. Therefore, it has unique advantages in mold manufacturing:
1. It can replace high-grade mold steel with low-grade mold steel or cast iron.
2. Domestic mold steel can replace imported mold steel.
3. Enhanced repair (remanufacturing engineering) can be implemented on molds, reducing mold manufacturing costs.
4. The application of laser surface hardening technology in mold manufacturing can integrate design, material selection, mold making, inspection, repair, and other technologies, significantly shortening the design and manufacturing cycle, reducing production costs, transforming the mold manufacturing method, and ultimately integrating and enhancing the overall level of the mold industry.
These advantages, whether in terms of technology, economy, or service, are unmatched by existing traditional technologies.
Laser melting technology applied to the manufacturing of mold cores
In mold manufacturing, the increasing importance of metal laser melting is the main reason. With this process, cooling channels can be set very close to the mold profile. For some complex parts with reinforcing ribs and mesh ribs of different wall thicknesses, cooling can be performed at the locations close to the profile that require cooling. In previous years, the flow characteristics of materials during injection molding were uncontrollable, but now their controllability can be achieved.
Through cooling, not only can production time be shortened, but also the deformation of parts can be reduced, with the cross-section of the cooling channel greater than 5mm.
Therefore, the cooling channel can be placed 2-3mm close to the mold profile for optimal cooling. Additionally, unlike cooling, temperature control can be achieved through such channels.
Laser surface cleaningand cladding technology:
This is an important process for mold recycling and repair. The development cost of a set of molds can be tens of thousands or even hundreds of thousands. The ability to repair molds is an important role of laser technology. By using laser technology for rust removal and other treatments on the mold surface, the mold can be kept cleaner, preventing further corrosion and improving the quality of mold application. The loss of the mold can be filled and repaired through laser cladding, restoring it to its original state.
