Use these common questions to prepare your material, marking content and project details before requesting a quote.

What materials can be marked with laser?

Fiber, UV and CO2 laser systems can mark metal, plastic, glass, paper, carton, cable, PCB and many packaging surfaces. The suitable laser type depends on the material and the required contrast.

Can laser marking create permanent codes?

Yes. Laser marking creates durable marks without ink. On many materials, the result is permanent, clear and suitable for traceability codes, serial numbers, logos and batch information.

Can you mark QR codes and barcodes?

Yes. Zertree machines can mark text, logos, QR codes, Data Matrix codes, barcodes, batch codes and expiry dates for packaging and industrial parts.

How do I choose the right laser marking machine?

Start with the material, code content, marking size, production speed and installation method. Zertree can then recommend fiber, UV, CO2, online, desktop, handheld or enclosed equipment.

What is the difference between fiber, UV and CO2 laser marking?

Fiber laser is commonly used for metal and some hard plastics. UV laser is suitable for low-heat, high-contrast marking on plastic, glass and packaging. CO2 laser is often used for paper, carton, wood, leather and some organic materials.

Can the machine connect with a production line?

Yes. Online laser coding machines can be integrated with conveyors, sensors, fixtures and production-line control systems for continuous flying marking.

Can I send samples before purchase?

Yes. You can send material samples and marking content. Zertree will test contrast, readability, marking speed and code quality before quotation.

What information should I provide for sample testing?

Please provide material type, surface treatment, marking size, code content, expected depth or contrast, production speed and any scanning requirements.

Can you help confirm code readability?

Yes. For QR codes, barcodes and traceability marks, sample testing can confirm contrast, size, readability and repeatability before machine selection.

Do you provide technical support and after-sales service?

Yes. Zertree provides machine selection support, sample verification, remote guidance, technical service and spare parts support for industrial marking projects.

How fast can Zertree review an RFQ?

For clear project information, the team usually reviews the request quickly and can help prepare a practical recommendation within 24 hours.

What should I include when requesting a quote?

Include your material, marking content, marking area, production speed, installation space, preferred machine style and sample photos if available.

Still need help choosing a machine?

Send your material, code content, marking size and production speed. Zertree will help review the suitable laser platform and sample testing plan.
