Frequently Asked Questions
How do I choose between Dot Peen and Laser marking for my project?
It depends on your material and requirements. Dot Peen is ideal for deep, permanent marks on heavy metals and withstands harsh environments like painting or galvanizing. Fiber Laser is better for high-speed, ultra-fine precision on various metals and plastics. If you are unsure, we recommend our Free Sample Testing to find the perfect match.
What is the main difference between Pneumatic, Electric, and Battery-powered Dot Peen markers?
Pneumatic models require an air compressor and are best for high-volume stationary use. Electric models only need a power outlet, making them quieter and easier to set up. Battery-powered models offer the ultimate mobility, allowing you to mark large, immobile parts anywhere without cables or air lines.
Can your machines mark on irregular or curved surfaces?
Yes. Our Pneumatic and Electric Dot Peen markers are designed with floating pin technology to handle slight surface irregularities. For complex 3D shapes or subsurface crystal engraving, our customized&specialized laser systems provide the necessary focal depth and precision.
How do you ensure the quality of the machines since you work with different suppliers?
As a professional solution provider, we act as your quality gatekeeper. Every machine undergoes a rigorous 48-hour continuous aging test and a comprehensive QC checklist before it is approved for shipment. We only curate systems that meet strict CE and FCC international safety standards.
What happens if the machine breaks down or I need technical support?
We provide lifetime technical support for every machine we sell. In case of a breakdown, our engineering team offers remote diagnostics within 24 hours. We also provide a comprehensive one year warranty covering key components to ensure your production stays on track.
What is the typical lead time and shipping process?
Most orders are processed and tested within 3-5 business days. Shipping usually takes 5-10 business days depending on your location
