In many large modern injection molding plants, the number of molds and corresponding tools and components is large, even in the hundreds of thousands. In the traditional way, operators usually use cheap and conspicuous water-based markers to write numbers on the different dies of the molds. With the demand of digital production and management, since the beginning of the 21st century, many manufacturers have started to use convenient dot peen marking machines for dot-matrix QR code marking to achieve efficient tracking and management of molds.Fast: our high efficiency dot peen and scribe marking machine can mark a standardized 10*12mm QR code in less than 10 seconds;Depth: our dot peen and scribe marking machines are achieved 0.3mm depth in one marking pass, and repeatable precisely for deeper;Traceability: our dot peen and scribe marking machines are able to mark QR and Data-Matrix code without deformation, easy to scan.

In the mold and die industry, the use of lasers for marking and engraving is more widespread than with dot peen or scribe marking machines. On the one hand, the development of fiber lasers for metal processing matches the development cycle of digital and intelligent production management, and on the other hand, contactless laser marking is more convenient than with conventional dot peen or scribe marking machines and allows for higher marking contrast.Easy operation: our laser marking machines are equipped with a red position indicator, especially the small hand-held systems, which are easy to operate by front-line staff;Flexibility: our laser marking machines allow flexible engraving on the surface or inside of the mold to achieve three-dimensional graphics or text effects after injection molding; Visibility: using MOPA fiber laser annealing or quickly scanned to white after deep engraving, our laser marking machines can generate high-contrast traceability content.

Laser welding is a common method used to maintain and repair injection molds. Molds gradually wear out during injection molding, die casting, and similar processes. Therefore, it is often necessary to fill cracks and gaps in the mold with laser tungsten fusion or other welding materials. This extends the mold’s service life, ensures production yields, and reduces long-term production costs by decreasing the number of replacement molds needed and the number of defective products requiring rework. Compared to TIG welding, the thermal stresses and hot zones of the laser are much smaller, which helps to prevent secondary cracking of the mold.Easy to use: our precision YAG laser welding machines for mold and die repair usually equipped CCD microscope to allow the user to visualize the operation.Precise: our precision YAG laser welding machines for mold and die repair can reach a minimum line width of 0.01mm and a processing accuracy of ±0.02mm.Efficiency: our precision YAG laser welding machines for mold and die repair reached 30 ~ 50 mm/s processing speed, and customizable for faster.

Molds can cause other problems due to residues, affecting normal production. In recent years, with the development of pulsed fiber laser and pulsed laser cleaning machine, laser cleaning of molds has been gradually accepted by professional injection mold manufacturers. The features of non-contact cleaning, no vacuum, no consumables, and non-destructive cleaning of residues through appropriate settings are well received by customers.Efficiency: the high-energy laser beam vaporizes contaminants in a very short time with minimal damage to the workpiece.Non-consumable: laser cleaning can be operated without detergents or catalysts, a significant savings for high-volume industrial metal derusting.Non-contact: laser beam can remove residue on molds at a distance, therefore suitable to clean hard-to-touch area.
