In fierce competitive markets in modern society, Brand truthworth will be planted in people heart tightly. Many commedites are marked with famous brand, on which their logos and brand patterns are printed or engraved in order to let people know that their brand commedities have high quality and enhance the truthworth to these commedities. Some business men want enlarge their brand popularity, they create their unique brand and consideration sale service for their goods in sale. Especially laser marking on zinc die castings are very popular.

We provide professional laser marking on zinc die castings and comprehensive process service to client . We also like to share our previous work experience with everyone this time. For laser marking on zinc die castings, has a general introduction to everyone with the follow steps.

Prepare zinc die castings

When client require these zinc die castings to be marked with their logos, we are all known that most of zinc die casting components are small and medium sizes dimensions. Laser marking is high efficency and cost efficiency for them. We will collect these goods and do a pre-treat ready. We must keep the surfaces of these zinc die casting components are clear, with no greases, dirts and burrs. After our QC inspectors check these goods good, these zinc die casting components are delivered to laser marking dept.

Choose Right Laser Marking Enquipment

For zinc die castings, We can select the right laser marking enquiqment to engrave custom logos and brand patterns on the surface of custom metal parts. Compare to laser marking on plastics, which is suitable for different laser machines. The follow is 3 types of ideal methods for right laser marking to choose.

Fiber Laser

It is suitable for zinc die castings, creates high precision, durabe marking on the part. It is also well-suited for engraving, etching, and deep marking.

CO2 Laser

It is typically used for both non-metal materials and metal materials. More can be used with certain coatings on zinc parts.

UV Laser

The laser marking creates extremely fine and detailed markings. Like logos or serial numbers, with minimal heat-affected zones (HAZ).

Design Marking Drawing

The laser marking machine always works with vector drawing to finish the task of laser marking. These vector files, such as  .AI, .SVG, .DXF, or .EPS. Use software like Adobe Illustrator, CorelDRAW, or AutoCAD to create the design. In accordance the dimensions on zinc die casting drawing, we scale the vector drawing appropriately on the castings drawing, and confirm the dimensions of laser marking label. Additionally the laser marking laser color required is also inverted if needed. Definitely the vector drawing is made by CAD software and until finished. At last,the vector file is saved and exported by vector file forma and stored on the USB flash drive disk.

Import Vector Files And Setting Up The Laser Machine Correctly

This step, we should import vector files into the system of the laser machine. Begin setting up the machine in accordance with the depth of marking label. Higher Speed, Lower Power for shallow engravings or surface marks. Lower Speed, Higher Power For deeper engravings. Adjust consistently parameters and testing the engraved result unitl resulting in satisfied effection.

Proceed the Laser Engraving Process

Once everything is set completely, run the engraving process on die casting components . According to the size and complexity of the design, the laser engraving can work for several seconds and minutes for each one. We can also make the reasonble jigs and clamps to attach each component one by one by manual, and ensuring a high effective production in large volume.

Post-engraving finish and reinforce engraving

After laser marking , there may be some residue or dust left on the surface of the components. We can use a soft brush or compressed air to clean residue off. For stubborn residue, Using typical isopropyl alcohol and a soft cloth. Additionally Look for any melting or discoloration caused by incorrect laser settings. Improve laser marking quality continuously until all of zinc die castings engraved acheive quality standards.
