Laser Marking & Engraving for Mold

In industrial production, the proportion of mold product production in the market has always occupied an important position. The marking information of hardware products mainly includes various characters, serial numbers, product numbers, barcodes, QR codes, production dates, and product identification patterns. In the past, most of them were processed by means of printing, mechanical scribing, and electric spark. However, the use of these traditional processing methods for processing, to a certain extent, will cause mechanical surface extrusion of hardware products, and may even lead to the loss of marking information. Therefore, mold manufacturers have to find another way to improve the quality of the products. With the development of laser technology, the laser marking machine and is expanding in the application range of the hardware mold industry by utilizing its excellent performance quality.

BEC laser marking and engraving systems are a fast, clean technology that are rapidly replacing older laser technologies and traditional methods of engraving. Compared with traditional embossing or jet marking methods, fiber laser technology offer various methods for permanent laser marking and engraving and can be used in many applications in the Tool & Die and Mold Making Industries. Most metals, plastics and some ceramics can be lettered, marked or permanently engraved with these systems.

In addition, the laser-marked text and graphics are not only clear and precise, but also cannot be erased or modified. It is very beneficial for the tracking for product quality and channel,  for effective expiration prevention, and for product sales and anti-counterfeiting.

Alphanumeric characters, graphics, logos, bar codes, etc. can easily be applied using laser marking machines and are widely used in industrial markets and tool manufacturing. As laser technology evolves, laser markers have become more precise and useful for an increasing number of applications on a wide range of component parts.

Laser marking and or engraving is a computer-driven, environmentally friendly alternative to mechanical engraving, chemical etching, milling, and many other costly, lower quality processes. In recent years, laser marking technology has proven to be a viable source for mold repair marking & engraving as many traditional engraving methods have failed to meet the continually growing standards for precision, depth, and quality. Alpha-numeric character sets or images are etched on various material surfaces, such as stainless steel, graphite, aluminum, and copper while providing high quality engravings.

Why choose laser marking machine for engraving molds?

Molds are tools used to make molded articles, which require precision, complex shapes, and a relatively high criterion for surface roughness and processing accuracy. Laser technology adopts to the molds due to its unique flexibility and precision, endowing the mold manufacturing process a finer texture engraving on the surface.

With a lot of advantages, including no consumables, no pollution, high precision, more clear and delicate engraving effect, laser engraving technology has surpassed the limitations of traditional texture processing, becoming more accurate, more exquisite and more high-end, which has significant advantages to the economy, ecology and design.


Advantages of laser marking machine application of mold:

Permanent. The mark will not fade due to environmental factors (touch, acid and reduced gas, high temperature, low temperature, etc.);

Anti-counterfeiting. The mark engraved by laser marking technology is not easy to imitate and change, and to a certain extent has strong anti-counterfeiting;

Wide applicability. Can perform laser processing on a variety of metal and non-metal materials;

The laser engraving information on the mold can withstand high temperature, corrosion resistance, wear resistance, etc. The engraving speed is fast, and the engraving quality is super fine.

Low operating cost. The marking efficiency is fast and the marking is formed at one time, the energy consumption is small, and the running cost is low.

Fast development. Due to the combination of laser technology and computer technology, users can realize laser printing output by programming on the computer, and can change the printing design at any time, which fundamentally replaces the traditional mold making process, and shortens the product upgrade cycle and flexibility. Production provides convenient tools.

Laser Welding for Mold

With the development of the industry, laser welding technology is constantly researched and innovated. At present, in the mechanical welding industry, the popular laser welding machine is due to its outstanding performance characteristics and shows good process characteristics during the welding process. So it can be widely used in many fields.

The mold in mold laser welding plays an extremely important role in modern industry, and its quality directly determines the quality of the product. Improving the service life and accuracy of molds and shortening the manufacturing cycle of molds are technical problems that many companies urgently need to solve. However, failure modes such as collapse, deformation, wear, and even breakage often occur during the use of molds. Therefore, laser welding repair technology is also necessary for mold repair.

Laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, and heat-affected zone. Small, small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, and easy to realize automation.

A typical example of the application of laser welding in the mold industry is the mold repair laser welding machine. This equipment is easy for operators to use, can greatly increase the speed of welding repair, and the repair effect and precision are close to beautiful, which makes the equipment It is widely used in the field of mold welding. The repair welding heat affected area of this welding machine is very small, and it does not need to be heated in advance, and the welded workpiece does not appear annealing phenomenon after work. This laser welding repair technology can not only be used to repair mold wear, but also can achieve precise welding of small and precise areas, and there will be no deformation or pores after repair.

Through the repair of the mold, the original mold can be fully used again, which greatly saves production costs and improves work efficiency.

Advantages of laser welding machine application of mold:

Non-contact processing, no external force on the welded parts.

The laser energy is highly concentrated, the thermal influence is small, and the thermal deformation is small.

It can weld metals with high melting point, refractory and difficult to weld, such as titanium alloy and aluminum alloy. It can realize welding between some dissimilar materials.

The welding process does not pollute the environment. It can be directly welded in the air, and the process is simple.

Small welding spot, narrow welding seam, neat and beautiful, no need to deal with after welding or only simple processing procedure. The weld seam has uniform structure, few pores and few defects.

The laser can be precisely controlled, the focused spot is small, and it can be positioned with high precision to realize precision processing.

It is easy to cooperate with computer numerical control system or manipulator and robot to realize automatic welding and improve production efficiency.
